Victron Quattro Combined With BYD B Box goes into passthru

Hi,

We have setup a Victron 10KVA Quattro with BYD B-Box 13.8.

The inverter goes into passthru as soon as PV drops off in the evening.

The battery sometimes discharges for a brief period, about 30 minutes or so.

Hi @jonjex,

Have you investigated the causes of passthru here in Q4 of the CCGX Manual FAQ?

From your description, it sounds like it could be the BYD is setting a discharge current limit of 0A for some reason.

Can you please check to confirm this by going into the BYD battery -> Parameters in the menu of GX device while in passthru?

Hi Guy,
