    Rabbit hole of batteries, inverters, and solar panels.

    What price should I expect?

    50kwh battery
    15kw inverter
    13 to 20kw solar

  • Isn’t there a national shortage of Goodwe batteries? We’ve been waiting six months for our install as Solarhart haven’t received stock in six months here.

      • 4.1 stars is actually quite high lol, every installer will have bad reviews as they can't all go perfect.

    • Hey Arkanis50,

      Yes the previous generation Goodwe Lynx 3.2kWh Batteries were in limited supply until about a month ago plenty of stock now with all distributors.

      This offer is for the new EHA batteries that have been released last month, we have bought multiple containers and stock levels are great.

      The industry overall has seen delays due to a number of factors but coming into end of year there is plenty of stock around just limited install slots.

      Cheers,

    whatever you do, please don’t go with a <10kw inverter, especially with huge batteries, thank me later :)

    • …why..?

    • -4

      It still makes sense for low usage households that utilise free electricity hours and prefer to export for $$$

      • +3

        The problem is, if you have a small inverter, you won’t be able to import much over the course of those free hours - so you may end up wasting battery capacity.

        Even in the scenario of low usage, it makes sense to pay a few $ more for a larger inverter for future use…

      • +1

        How does it make sense? Exporting with 5kw inverter will always be less/slower than a 10kw one. Imagine joining VPP, you are basically halving your earnings during peak selling times, plus you are charging less battery during free charging hours.
        Also, even if the household doesn’t have AC, just by turning on the iron, the kettle and the oven at the same time will trigger grid usage as the huge and full battery cannot supply more than 5kw due to the inverter

        • -2

          When I'm ironing clothes I'm not boiling the kettle whilst simultaneously cooking dinner. I've only got so many hands.

          With our new hot water dispenser it takes 40 seconds to make 200ml of hot water costing 1 cent I'll live with that.

          • @mysterytal: Sorry I didn’t know you live in a-one-member household, my bad then, you probably do not even need solar/battery.
            Oh and if you use a charcoal operated iron, you won’t even need 2000w of power when you iron your clothes.
            :)
            Jokes apart, even if your usage doesn’t peak over 5kW, you will be selling excess power very slowly with a 5kW inverter

            • @GregFiona: Why would I want to sell more of it? The export limit is 5kW in our electricity distribution area so this would be ideal. We cannot export any more than that. We have a 10kW solar inverter and it's very limited. It would be nice to have a 10kW hybrid inverter and export at 10kW but Ausnet won't allow that. Family home but even still there isn't someone ironing whilst someone is cooking with someone else boiling the kettle as well.

              • @mysterytal: So you are also telling me
                that during peak hours your household usage is also
                zero, and that doesn’t affect the 5kw inverter and export limit? Again, my bad, if all households were like yours then those wouldn’t be peak hours.

                • @GregFiona: This is a targeted deal offering a 5kW inverter with a low headline rate to attract people to click on it. There is an option to upgrade to a 10kW inverter for an extra $1,000. That's not bad. That'll allow 5kW of exports and 5kW of self consumption if exporting is important to you. At the very low feed in tariff being offered I'll keep the very limited 16kWh for myself.

                  • @mysterytal: I’m happy for you, I still just think that spending money on a new solar battery system and going for a 5kw inverter is a waste of money(down the track) when, for a bit extra $$$, you can have better system that will perform better, will not bottleneck your setup, will handle better backup protection, and will speed up the payback period in case one decides to VPP it.
                    I paid $6500 8 weeks ago
                    for my 10kW inverter, 42kWh battery system DC coupled with existing solar with 2 backup circuits, in less than 2 months I have saved $900, if I had gone for a smaller inverter the savings wouldn’t have been the same for many reasons(EV charging, pump, we do cook and iron at the same time) https://imgur.com/a/YGlHkFa

                    • @GregFiona: The most this deal with a 16kWh battery and a 5kW inverter could save a household is $120 per month. It's not possible to save more than that. That's discharging at 1kW for 16 hours recharging at 2kW for 8 hours per day at an average unit rate of 25 cents per kWh. 25 cents is an easily achievable rate in Victoria the state that this deal is aimed at. The minimum time using it's maximum capacity every day to pay for itself is 4 years. Most households won't use it's maximum capacity every day. An EV battery should not be charged using another battery instead being charged direct from solar or on an EV tariff. It might be a waste of money but it's ideal for many households who don't use a high amount of electricity.

                      • @mysterytal: “an EV battery should not be charged using another battery”You have got this so wrong mate that I give up!
                        Who told you that you shouldn’t charge your EV using solar battery?
                        And you believed them!

                        Also, if you think that you will be discharging a 16kWh battery to zero(16hours x 1kW) something tells
                        me that you have never heard
                        of the term “minimum SoC”.
                        Another thing that you missed is that electricity tariffs are always going up.
                        I will keep advising my friends and family on how to invest their money smarter(Better ROI, save on multiple levels) and you can keep on promoting a 5kW inverter (or better, advise to buy a cheaper, 2kW inverter, that’s plenty according to your calculations)as a good option for families that don’t cook & iron at the same time!
                        This deal is far from ideal, but I’m not wasting any more time, I gave you real data, you seem too narrow minded to grasp my point.

                        • @GregFiona: Being in the Ausnet area with an existing 10kW solar Inverter the maximum we can have is a 5kW inverter.

                          The battery is actually an 8.3kW module. The minimum SOC has been taken into account.

  • Good day Matt,

    Any deals for existing customers? I had previously installed REC panels and GoodWe inverter(9.7KW panels and 10KW inverter) with you guys at Doreen(excellent experience by the way) and hoping to join the solar-battery bandwagon.
    Hoping to get this to have the essential-ckt backed-up(blackout protection) and possibly replace my existing 10KW with a new 10KW inverter and 24KW battery

    • +1

      Hey 4frodo,

      Good to hear from you mate and glad the system is doing well.

      I have sent you a Direct Message on OZB happy to quote up based on your needs.

      Definitely recommend replacing current inverter and going DC as we have done the initial install will be straightforward.

      Cheers,

      Matt
      Cerium Energy

      • sure, replied to your DM and happy to work with you guys on a ideal-setup.. :)

  • How does this compare to Sigenegry and can the Goodwe do full home backup (inc ducted aircon)?

    • +1

      Hey Captainballbag3,

      Great question mate, Sigenegry is more of a premium product with the price point to match.

      Goodwe technically can do full house backup however we don't recommend it due to its inverter limitations and output during a blackout (similar across most mid range brands). Depending on your needs and battery capacity most customer wont be using refrigerated aircons or ovens during a blackout to ensure they have enough left in the battery to last the length of the blackout.

      You can set a reserve level in the battery to ensure it does not discharge below that, this ensures that in case of a unplanned blackout you have a set level of battery power available.

      As we cant predict when a blackout will happen it hard to know how much power you will have in the battery, thats why the reserve level is a good feature, that being said you don't want to keep a large reserve as you want to use your battery in normal day to day use.

      Now if we DC couple the battery system (solar panels directly connected to the battery inverter) in case of a blackout these panels will continue to product power and charge the battery. This is great if the blackout is at a time the sun is out or lasts over multiple days and you have the opportunity to charge the battery from the panels.

      Considering all the above we recommend to not have major appliances like refrigerated aircons, Ovens, EV chargers etc on backup to ensure you dont exceed the inverter limit and/or drain the battery very quickly. That being said the inverter limit for backup is 63A maximum so our sparkies can work with you on install to wire up extra circuits at an added cost with the disclaimer and understanding of how the backup works and how to ensure you dont exceed these limits.

      As you can see its a case by case basis and each customer has slightly different needs so we work with you to work out what is important to you and ensure you get the best possible setup for your needs within a reasonable budget.

      Sigenenergy on the other hand can do full house back up, especially for customers with 3 phase power backup. Its a great product which can incorporate smart loads, EV chargers and has a lot of great finionality.

      We understand everyone has varying needs and budgets and we work within them to quote the most appropriate product.

      Happy to discuss your specific needs and go from there.

      Cheers,

      Matt

  • Paid about that in Vic for 10kw inverter & 42kwh Fox ESS battery, was torn between Fox ESS and Goodwe but I am liking the Fox much more than my existing Goodwe inverter/app.

    Was speaking to my installer and I think the price for the Fox ESS battery has gone up to $7000 now since they are installing in January now and rebates will drop a bit, but much bigger capacity battery makes more sense imo. Benefit over my existing goodwe for me is the ability to control it all locally via modbus (get data updated every 10 seconds rather than waiting for cloud to update)

    • Do you mind sharing your installer details?

      • Sure, send me a message and I can refer you

  • Hey Everyone,

    Just thought I would put an update re Goodwe App and monitoring. Goodwe has just released their new Sems + AU/NZ app which looks great at first look and has a lot more detailed info with much better UI and data available.

    Link to app here: https://apps.apple.com/au/app/sems-au-nz/id6755710856

    Extract of app here: https://files.ozbargain.com.au/upload/361730/125973/goodwe_s…

    Goodwe is a quality brand that has listened to customer and installer feedback and made a product that's easy to install and commission as well as easy to manager for end users at a great price point.

    A few of our customers have started the new app and reported back a positive experience, much better than the previous app.

    Cheers,

    Matt
    Cerium Energy

    • The new app is really good. Modern UI. But functions are very similar. The charts have made a bigger improvement.

  • Hey Matt, saw some reviews that the new ESA product has been hitting chamber temps of over 50 degrees.

    Considering it isn't even peak summer yet and given that the inverter sits in the same stack as the battery, would that potentially be a concern for battery longevity or even system shutdown on the hottest days? I think I read that it uses a fanless system and relies on passive airflow?

    Could I get your thoughts on this please?

    • How do you check chamber temps ? As per app mine was 35c yesterday. Garage install.

    • Hey Kazer,

      Cheers for a great question.

      So yes battery temps can get high especially if sitting in direct sunlight, the key here is to install is a area which does not get a lot of direct sunlight (North facing or west facing is normally a no go).

      After a certain temp the batterie start to derate (meaning produce less power until it cools down again), normally 40 Degrees plus, this is cell temp not outside temp.

      We haven't seen a lot of 40 to 50 plus temps, if installed property with good ventilation should not be an issue.

      Now garages can also get really hot in summer so we suggest a small pedestal fan for airflow and/or cracking the garage door or backdoor some good airflow.

      Key is keep out of direct sunlight (same for inverters). We can add a canopy cover but it wont cover the whole thing so best to keep it out of direct sun as much as possible.

      Through the quote process we will discuss battery placement and work with you to sort out the best location for the battery.

      Cheers,

    Just had a Sig install from Cerium, all went well and everything done in a neat and tidy way as we requested with a fair price.

  • Are Longi 370w LR4-60HPH off the CEC list now? Wanting DC over AC coupled and would rather not have to bin the panels

    • +1

      Hey Lolitsjoel,

      No issues with these panels we can DC couple, we just need to make sure the installation is up to current electrical code, this can include earthing each panel, adding DC cables in conduit, adding Disconnection Points (DP) on the roof instead of DC isolators.

      Requirements can vary based on when your system was installed and what components are on it.

      Best to get in touch and can advise accordingly.

          • @mattcerium: Cheers mate. Had a phone call to a seller the other day and they said they're not on the CEC list anymore and cannot do it without removing the panels.

  • If we already have a Tesla battery can we get one of these as well?

    • Hey 1Kenobi,

      Unfortunately wont work too well as there will be 2 batteries that wont speak to each other and cause a number of issues. In these cases we would remove the Tesla and add a new battery.

      Depending on which Tesla you have, the PW2 has been discontinued and no stock left anymore so cant expand (quiet frustrating for many Tesla customers). We have removed a few PW1's and replaced with various battery systems under the new rebates.

      Mixing battery brands and tech doesnt work too well as they cant communicate with each other and both will work against each other to charge and discharge.

      Happy to discuss more feel free to give us a call or email on info@ceriumenergy.com.au.

      • so far we've got 6, 2 were quoting the old lynx batteries, 2 were for foxess, 2 were for over 15k for 20kw goodwe esa's

        I'm like pretty sure I could give you guys tickets to fly to adelaide and back and still get it done cheaper :|

        Will keep looking…

  • I've now been told several times not to "waste" my money on this. I wonder what a cheaper alternative would be. Our distributor limit is 5kW battery inverter and this is 5kW so can't go any bigger unless we replace the whole lot so that obviously must be the path to go down.

    I was about to jump on this deal but the comments earlier have put me right off spending anything.

      • We've already got a solar inverter. This would be added to the existing system.

    • +1

      Hey mysterytal,

      Totally appreciate where you are coming from.

      Assuming you are in the Ausnet area, and yes they have a 5kW battery Inverter limit. To get around this we can remove your current inverter and DC couple the current panels directly into the Goodwe Battery Hybrid Inverter. This allows you to have a total 10kW inverter on single phase which is connected to both panels and battery.

      Now I can appreciate that means your current becomes effectively useless not much use for it, some customers sell them second hand (not worth much).

      Happy to chat mate see what your needs are and see if we can help you out.

      Feel free to reach out.

      Cheers,

      Matt
      Cerium Energy

      • Thanks Matt,

        Yes in the Ausnet area and I've got a quote from you just trying to get someone else to support me with this offer. I'm sure it's a very good deal but others are very sceptical which is making me nervous. They're saying it's just too small at 16kWh and not worth wasting a rebate on even though usage has never exceeded 10kWh per day.

        The house has solar panels which are well over 15 years old and connecting them to a new inverter wouldn't be worth it. Replacing it all with a 10kW inverter and new panels would all cost way too much. The current panels have no value.

        • +1

          Hey Mate,

          Right that makes sense, yep being that old definitely not keen to try to DC them. It would almost be better of ripping it off and adding a new system.

          Larger battery system definitely makes more sense since only $500 per module. All comes down to how you are going to utilise the battery and if grid charging or relying just on the existing solar, thats where the inverter size matters.

          Send through your NMI and meter number and we can run a quick pre approval to see how we go with Ausnet no harm in checking.

          In terms of waste of money thats a very subjective term, batteries save money thats a fact and its about designing the right system that works for you within a reasonable cost. Goodwe hits the nail on the head with this, stackable and priced extremely well for the solution they offer.

          Feel free to give me a buzz mate happy to run through the pros and cons, no sales talk just some facts and a chat you can make the call how it suits you. There have been a few times where I have myself told potential customers that a battery isn't worth it for them and to rethink it later.

          At the end of the day you get 1 shot at the rebate so you want to se it wisely.

  • Hi Matt, at what age does solar become not worth it / too costly / too much risk & hassle to DC connect? My system is 7 years old, 6.6kw panels, for example. Thanks

    • Hey Mate,

      Really depends on how good the install was when it was done. To put a number on it within the last 3 years = Easy minimal issues. 3 to 5 years = decent have to upgrade a few things. 5 years or more can cause some headaches. 7 to 10 years or older = no go.

  • Just requested for a quote. Hoping there's still stock. Also will be adding some some panels and DC couple the new and existing panels.

  • Has anyone had any updates from Cerium after accepting their quote? I accepted the quote and sent the email with the requested information on 16th December and I haven't heard anything back since.

    • Hey Mate,

      Appologies for not getting back to you immediately. Our Christmas New Year shut down has just started as of 18th Dec however we will be avaliable over emails throughout the break.

      Once accepted your job is secured and we will process accordingly.

      Your install has been allocted to the calender. This offer has been very popular and we are scheduling installs based on acceptance date and will be in touch in Jan with dates and go from there.

      Wishing yourself and every one on the Ozb community a Maerry Christmas and Happy New Year.
