Inverter & Battery size compatability

Recommended Posts

I am looking to getting a Hybrid inverter & battery with the option to add panels at a later stage. I am now trying to work out whether I should get a 5kw or 8kw inverter. I had thought i could get away with a 5kw inverter/battery. But after looking at my appliances, etc I realise that we have a very high load in early mornings & evenings. So am leaning towards the 8kw. However, THE PRICE DIFFERENCE IS HUGE & I have limited finances. Is it possible to have an 8kw inverter with a 5kw battery? This would help reduce cost bit (the bateries being the expensive component). The system would be Sunsync.

Rather get the 8kw inverter as it allows more flexibility and yes having a 5kw battery is fine.You can usually add about 10 batteries into your system depending on the inverter etc.I have an 8kw Sunsynk and 3 x Hubble am2 which are 5.5kw each.

Thank you. Would definitely rather have more than what I need with regards to the inverter. Then when there is loadshedding be extra careful on the battery. With so much money stake, I can't afford to make a mistake!

As long as it's clear that you will not get full off-grid performance out of your 8kW inverter until you've got enough batteries connected, but the 8kW will give you greater headroom for pass-through of grid power while there's no loadshedding on.
