Looking to install a 50kwh Hinen battery with 10kw inverter or 15kw inverter
on top of my 13.2kw jinko panel and 10kw sungrow inverter?
Hinen seems to have same battery life cycles of those of sungrow and sigenergy and have a slim design.
I was wondering what costs i should be expecting and if you have installed Hinen before? what cost did you get?
what is that suppose to mean?
Nothing much, it's just JV trying to get his comment count up.
Can't speak much about the Hinen batteries. The AI summary seems to be positive thought:
Hinen batteries are generally well-regarded for home energy storage, with customers praising their reliability, safety features, and long-term value. They are considered a good option for maximizing solar savings, increasing energy independence, and providing backup power during outages. While some users have reported minor issues with integration into Virtual Power Plants (VPPs), overall, Hinen batteries are seen as a solid choice for homeowners looking to enhance their solar energy systems.
jv has difficulty understanding anything made after 1995. The idea of clean energy stored silently in a battery makes him deeply uncomfortable, so he mocks it out of habit.
Maybe research the envrionmental impact of these batteries….
@jv: Maybe research the environmental impact of not having these batteries….
LIFEPO4 - so no rare earth minerals.
its more expensive to have the batteries than not have them
how so? most ROI calcs would put it at 3-4 years with rebates currently
Depends on usage, didn’t make sense for me.
My roi would’ve been 7-9 years even with 20% more usage.
So you make a blanket statement based on your personal scenario?
100% the same in my case with a 4 person household. There are ~5.7KW worth of solar panels with a 5KW inverter.
Our daily usage is 7.5kWh purchased from the grid and 13kWh sold to the grid (averaged over the past ~7 years).
Assuming an average of 35c/kWh to buy and 4c/kWh to sell… that's only ~$2.105 a day or $768.33 a year. Being a low income household (parent's place)…. we get $285 a year as part of the "Low Income Household Rebate" coupled together with the $150 yearly "National Energy Bill Relief".
That brings it down to $333.33 per year (excluding churning credits). Even if those scam battery instagram ads promoting 50kWh batteries for $5499 fully installed were real, it'll take me 16.5 years to make my ROI.
@Bignudge: a household that barely uses electricity does not see benefit from batteries to save on electricity costs. who would have thought?
My solaranalytics put ROI at 20-30yr (pre rebates ?)

solarquotes used to say 30yr, now after rebates say 8-9yr
amber seems to make it up on generic info
retailers claim 3-5yr
this really pushy co electrifying australia says 2yrs, and kept trying to word-corner me into buying
I duno who to believe.
no one. you base it on your bill and what your usage pattern is. if you have a smart meter it's easy to figure out, battery ROI depends on 1. how much you use, and 2. when you use it. you can then factor free charging/VPP aetc around it. solar quotes has a detailed calculator for those purpose
@V2L: solaranalytics IS the smart meter. So $450 ROI/yr
much does not change much with the size of the battery
Amber is making assumptions about high export earnings that is not calculated into this one
solarquotes/Amber Does not take into account the time of usage so I don't see how those can be highly accurate.
@furyou: I can see exactly how many kwh I use per hour 24hrs a day on ovo/energyaus usage. easy to figure out how much the battery will save me without using any calculators
@V2L: I can see how much I used, but a battery doesn't guarantee you don't use any of it right? It's not just that I use 18 kilowatt hours from the grid therefore if my battery is over 18 I will never use anything from the grid.
Amber could be doing something. There are negative Fit.
Anyway the Bunnings calculator says I could save $10 a month. 118 a year with their battery! 140 year pay off
@furyou: it depends on the size of the battery and capacity of the inverter and when you draw the power
for example if you want to keep ducted aircon on overnight and it draws 4-5 per hour overnight from midnight to 7am you'd need about 30kwh battery which will fully discharge - so you'll need closer to 50kwh. the other question is whether you can fill up the battery during the day - generally each kw of solar panel gives about 4kwh per day. plus any free charging from grid you might utilise for example ovo 11-2pm free window lets you charge about 30kwh in 3hrs with a 10kw inverter
and then it's a case of how much the battery costs vs how your bills would look like without it
I wouldn't do the maths based on VPP - too many variables.
