Hi all, this is a new installation by me, using 2nd hand parts. Quattro 1000/48, two MPPT 150/60s and a Color Control GX. Plus three Pylontech 2000W batteries and 2 x 2400W PV strings.
At the moment, even in full sun, the system is running the load from the grid. Batteries are showing 100%, PVs are showing good voltage, but the Quattro isn't using them.
Yesterday I tried switching it to Inverter only, it dropped the supply completely then rebooted, after a few minutes it came back up using the PVs.
But when evening came, it did not switch to batteries, it went directly to grid. And then this morning again its stuck on grid.
Anyone any ideas what could be causing this please? Maybe I have some settings incorrect.
Help appreciated.
