Dual inverters

[Sebastian G]

Hey,

I am looking to install new solar system and I have received a good proposal, the installer recommends to install 2 Inverters 1 Fox ESS 1 x KH10 to cover 3 different roofs with 6 PV on each side house and 1x FoxESS F Series 3.6kw Inverters for garage roofs.

Now i am getting bombarded with solar companies trying to get my business and some are telling me that the 2nd Inverter will not charge the battery and would also need to be a hybrid Inverter ? Installer told me that smaller F series Inverter will be sync with the hybrid and both will charge the same battery system.

I am going with 2x Fox ESS EP11 10kw batteries for the system. I think it will all be sync and should all work if installed at the same time right ? Also some are telling me that I will be fine with just 1 Inverter, because my roofs are facing the same orientation as on the house and garage ? I have attached the layout for better visualization.

So two questions really, do I need 2 Inverters and will both charge the batteries and if I can get away with just 1 Inverter (1 x KH10 ) ?

Thanks for all

Hello,

Good news, the KH10 with two EP11 will also be able to charge from surplus solar generated by your garage string only inverter. Those installers who say it won't work clearly don't know what they're talking about.

So to confirm, go with one KH hybrid with the two batteries connected and the F series string inverter for the solar only array, which WILL be able to see seen by the KH and hence charge the battery. I personally do this and have done a lot of installs with a combination of string and hybrid inverters working great.
