Dyness 8kw inverter + 10kwh battery. Is this a good package?

Seems good to me going by specs and price.
I don't know the site so it would be good to verify that.
The brand is well known but just double check that the inverter is on your municipalities list of allowed inverters.
The 10kwh battery is nice but just be aware that you will need to upgrade at 10 kWh per upgrade.
Having the single battery limits you to 5KW battery draw so you will need to limit the amount to that during loadshedding/power outages.
 
Yes, rather get two 5kw battery they are not even more expensive then the 10KW combined

So even if you have a 8kw inverter you can only draw 5kw max?

What is the max draw from a 5kwh battery?

As the others mentioned you need to have a look at the Max C rating. You can draw more but you usually lose your warrantee then.

The inverter can blend power though so once you have your PV panels it can blend from battery, Grid and PV to get to the full inverter spec.(8+kw)
When the inverter is configured you need to tell it to never exceed the C raring of the battery then it will manage the blending for you.

Thank you for the explanation.

Another question then. If I paired my 8kw inverter with a single 5kwh battery rated at 1c, how many kw would I actually be able to use during load shedding?

(This is until I can add the second battery and then the solar panels later).

1C means the battery can be fully charged / discharged in 1 hour. So a 5kwh battery can be discharged / charged at 5kW. 0.5C means it takes 2 hrs so a 5kwh battery can be charged / discharged at 2.5kW

Maybe its better if you describe your intended use then people can make recommendations based that.

There are many ways to wire inverters so if you are wanting ovens, aircons and geysers on the essential side of the inverter its very different than just having lights TV and the odd plug.

So my 8kw inverter will then be able to supply a maximum of 5kw with a single 1c battery, is that correct?

Is that a problem for the inverter?

No it will be able to discharge whatever is needed unless it is set but discharging / charging a battery beyond its rating affects it's lifespan.

For now it will be lights, plugs and inverter aircons with 48000btu total. No geysers for now.

Occasional use of kettle, air fryer, hair dryer, toaster. Never all at once.

Later will add geyser and some other things. Hence the 8kw instead of a 5.

Dude, any heating or rapid cooling chows electricity

Stove Oven
Aircons
Kettles
Microwaves

Hence why people go with gas stoves/ovens.

Kettles - newer kettles are 2000w vs older 3000w ones.


48000 btus is 4 12000btu aircons. My 12000 btu inverter ac uses 1kw over an hour at max cooling or heating, and 500w maitaining.

So you going to run your battery flat in 1 hour.

You either buy more batteries or dont run your aircons.

OK thanks for the advice.

W.r.t. dyes or sunsynk inverters, these have the same hardware, but differrent software. Both are recognised as good choices. I have my Sunsynk running since Aug 2022, 24hrs/7days 365.

If budget is an issue, rather get 10 panels and 1 battery. During the day with 10 panels, you can be completely off grid for most months.

or don't use max cooling, just enough to take the edge off. I run my 12000btu inverter aircon and it sips at 250W off my 12V inverter.
