When the batteries are full, we still have PV power available, but our grid operator doesn't allow feeding or we have an off-grid system, that power is lost. We could use that power and send it to a boiler or something similar. For this we are using a device from My PV called AC-Thor.

The schematic for the ESS system looks like this:

First setup:

Ac-Thor device must be connected on the AC output of the Multi/Quattro.

Must be in the same LAN network as Color GX or Venus GX, with DHCP enable (default).

Using the device touch screen, select Information menu and go to the third screen to find the current IP address.
