spotity Posted June 30, 2023 Share Posted June 30, 2023 Can we get some more info? What inverter? Quote Link to comment Share on other sites More sharing options...
Proff72 Posted June 30, 2023 Share Posted June 30, 2023 It really depens on which inverter you have. I have the Kodak Hybrid off grid 7.2kW and it cannot start without a battery. Friend of mine has an older Goodwe 6kW grid tied inverter and it can start without a battery. gryphon25 1 Quote Link to comment Share on other sites More sharing options...

gryphon25 Posted July 6, 2023 Author Share Posted July 6, 2023 Sorry for little info before. It's a SUN 2kva inverter. It didn't work without the battery connection Quote Link to comment Share on other sites More sharing options...
gryphon25 Posted July 6, 2023 Author Share Posted July 6, 2023 Does anyone have any info about these inverters? The fan on mine just keeps running even when it's on AC bypass. Quote Link to comment Share on other sites More sharing options...
Scorp007 Posted July 6, 2023 Share Posted July 6, 2023 I think an inverters core function is to produce 220V AC either from battery or from PV. True hybrids do it from either/both. Quote Link to comment Share on other sites More sharing options...

Some always stay on and ramp up. Budgetish ones tend to be louder-er permanently gryphon25 1 Quote Link to comment Share on other sites More sharing options...

I can't cope. I have it in the living room at the moment and was planning to mount it in my office. Guess I'll just have to keep my noise cancelling headphones on PsyWulf 1 Quote Link to comment Share on other sites More sharing options...

The Kodak 7. 2 actually can power up from grid only, or pv only. So it does not insist on battery power being available. gryphon25 1 Quote Link to comment Share on other sites More sharing options...
WannabeSolarSparky Posted July 8, 2023 Share Posted July 8, 2023 (edited) growattspf5000es runs perfectly without a battery but you need to decent solar panels and NO clouds. Not really recommended/ideal to run like this. You would rather run a grid-tie inverter if you do not have batteries.
