How do you deal with Inverter heat?

If I could, I would just hook the fans up to the DC from the panels.

 

No electricity from the panels and they are on.

 

No electricity from the panels and they're off, but there's no real heat anyways. 

 

I've tried that in the past with my original micro-inverters. The net result was that the MPPTs wouldn't start at all 😞 

 

I never investigated why, just used a mains power supply, current fans run off a 12V regulator from the battery packs.

Can you give me the PCB and thermostar order details please?

Also the details of the installed fans please.

Huh, that's good to know.

pcb has 2 channels . i bought it in case i have second inverter in the future. splitter is used to divide power to 3 fans so only one channel is used. whole enclosure is DIY connected with piece of aluminium  and wood

I think that is going to be a problem for me also as I have 2 3 phase multi-point water heaters. From memory I think one draws 11 A / phase when on the 'hot' setting. That would be 22A per phase if both units are on plus anything else.

Maybe best to route the heaters wiring only from the grid, but for my place, a difficult wiring modification.

It is not a problem as long as there is grid power, the Deye inverter  will take the additionally needed power from the grid. The inverter rating is what the inverter can produce from pv and/or battery.

Can I contact you to find out more about your inverter as this is someone else's thread?

Yes but please open a new thread for it so we can discuss it there to the benefit of other readers who also can contribute with their knowledge.
