Hi folks,
I just want to make sure that I have the right idea when it comes to backup generators
At some point I'm likely to upgrade my Solar with more panels and batteries and will either have a 15kVA Quattro or 2x 8kVA ones
I'd like to setup the system for a small backup generator in case there's a severe power cut
The idea would be to get a smallish generator (around 5kW) and run it when the battery SoC is low and I'm not getting enough power from the panels. The generator would then run for a number of hours to charge up the batteries when enough power to see my through the rest of the day
From looking at the generator FAQ, I'd be significantly below the recommended generator size. But I think that is designed for a situation where the generator needs to handle the full load of the house. In my case this wouldn't really be applicable, worst case I'd be running my heating system and some lights which should be within the generator output
I understand that I would need to limit the AC1 input power to ensure the generator isn't overloaded. Any other considerations I should think of?
Also, if I'm using a Cerbo GX, do I need to use the Generator relay on the Cerbo to remote start the generator? Is there any advantage or disadvantage to using the relays on the Quattro?
