Anyone here own a solar edge system and have the solar edge battery with the backup interface? Solar edge is offering owners a free battery compatible inverter upgrade with battery purchase. The free inverter (plus new warranty) with the government subsidy is making the battery more worthwhile. Anyone have a solar edge system with solar edge battery and thoughts on it?

Thanks. Haven't had any issues like that here. I will say my first inverter only lasted 5 years but with a 12 year warranty I'm not worried. My installer hasn't had any issues with Solar Edge and while I was waiting for the new inverter they gave me a loaner to install.
The system was still working, it's just that it was underperforming, the average person wouldn't have known any different.
Towards the end of part three in this page explains it.
https://mcelectrical.com.au/blog/solaredge-inverter-optimise…Thanks. Yes, think I saw this post before when I went digging a while ago for feedback on them.
Just curious how did you end up finding out it underperformed?
The short answer is to look at your optimiser voltages, if it's maxed out (60v for standard optimisers) your panel's output is being reduced as the ones in the shade don't have enough power to match the current of the sunny ones. This occurs because a string needs to make up a set voltage and in a series circuit current is the same through the entire circuit.
My system has 3 arrays on 2 strings. North array has its own string, east and west are in series. In the morning the north panels were producing more than the east, even though the east had more sun. In the afternoon, the west panels would do the same. In the end I got 80v optimisers fitted, this allowed one array to make up the required string voltage almost on its own, with the dark side not required to do much.
I've been edging to the thought of storing solar in my battery. I guess you could call it solar edge.
I've had a SolarEdge system for about 5 years.
No issues at all.
My father also has a SolarEdge system with a 10kW battery. He's been happy with it. no issues so far.
I'm planning on getting a battery with the free inverter upgrade shortly….Thanks. Yeah my inverter died after 5 years and just discovered a DC optimiser has failed, one out of 24. Mainly interested in the battery because of the free inverter and then an entirely new warranty to go with it.
yeah, the new warranty is nice!
You may as well ditch solaredge altogether and go back to string, they have overblown the problem of string inverter for their own agenda and create another bigger problem to fix it with a bigger price tag with questionable performance so I doubt they will come up with anything more affordable and reliable. Just go with the well proven and simple system. The Chinese has won the race so there's no point sticking with the loser because it will come back biting you on the long end.
Unfortunately for my house string doesn't work or is completely terrible. Roof faces three directions and only enphase or solar edge were the best choices. I agree they are over engineered and if we ever move house provided it is oriented better I would definitely go string with a good quality brand Chinese inverter.
However, the inverter has a 12 year warranty and the DC optimisers have a 25 year warranty. That includes labour but yes I am aware a warranty is no good of solar edge doesn't exist. The installer I went through is local and has been around for a very time. So I'm not worried they'll Phoenix.
Solar edge offers a new inverter ($2100 value) with a 10kwh battery purchase. Plus the government subsidy it makes it very attractive. The only other local installer is offering a Franklin battery that obviously no new inverter because it's not solar edge and while it is 13kwh it costs 30% more even after the rebate.
Power wall V3 apparently now come with an inverter, so it seems they are all trying to lock you into their eco systems. Yes, is over engineered but it works, warranty is good and they have a great deal on battery with free inverter.
Roof faces three directions and only enphase or solar edge were the best choices.
GoodWe has/had a 3 string inverter. For me it was $700 less than SolarEdge, wish I'd gone with it after the debacle with mismatched SolarEdge strings/optimisers.
$700? Honestly I would have still gone SE then. However, at the time of install my only options through local installer were SE or Enphase.
The savings for going with goodwe or other Chinese products is a lot more $700. There is no way solaredge can compete. If you are willing to go ac couple the savings is gonna be heaps further.
having 3 roof face is not the excuse for going solaredge, if you're slightly technically minded solaredge option actually introduce further complications so it's actually a moot point.
Goodwe and sungrow hybrid and a couple of other brands actually have 4 mppt now, they have been doing 3 mppt for ages.Unfortunately at the time the options from all local installers were SE or Enphase. There were no other choices from local companies. So DC optimisers or micro inverters. Regarding battery, besides SE battery the only other local option is Franklin 13kwh AC coupled install which will cost $11k after rebate. That's more than SE 9.7kwh battery which includes a free inverter worth about $2100 which comes with another 12 year warranty.
Where do you live, neovolt is offering 30kwh ac coupled for $5-6000 for pretty much the whole nsw/qld, outside of that its not hard to find alpha ess option around the country for not much more. You have to do more homework. Franklin is just another variant of Chinese manufacturer so I wouldn't pay that much. With so much uptake from alpha ess/neovolt it's a safer bet to go with them rather than some less known brand your local installer is trying to offload for a fat margin.
NW Tas. There's no more homework to do mate. You have no idea what the solar market is like here. Limited installers and prices here are nothing like the mainland. However, this is way off topic already. Thanks for the feedback though.
@tessel: If I were you I'd just drop the idea and wait for a year or two then you'll come up with some better deal. Battery price is on the downward trajectory, it will fall in line or faster than STC so you'll end up with better tech at cheaper price. You're in Tas and there's little incentive and savings to spend that much for a measly 10kwh battery because pay back is more than 10 years, given Tas already got very stable grid and well regulated energy retail, you will not see price go crazy as SA or NSW to make the saving worthwhile.
So I found the SE batteries not competitive and it was going to be a heap of work to change it all over. I am leaving the SE PV system as is, untouched, then installing a battery only AC coupled Neovolt system.
This solution has also been forced in part by Energex policy
I have a SolarEdge inverter system with the optimisers, but I'm reluctant to go with their battery after my experience.
It needed the higher voltage optimisers, yet their customer service agent proposed installing extra panels to balance it. If I had room for extra panels I would have put them on to begin with.
In the end the installer fitted the correct optimisers at their own costs. SolarEdge refused to share any of the costs. The installer said they're no longer installing SolarEdge after this.
