Since most 550w panels have Voc around 48v... You'd get around 7 PV x 2 strings you'd get around 336 Voc which may be good enough for MPPT. I would suggest you the couple new ones you're gonna add, add them in one string each so the voltage remains similar on both strings generally.

We're using Tubular Lead Acid batteries. The battery is showing its voltage on the Device -> Inverter (Logger) page as you may be able to see in the screenshot. But it is not showing anything anywhere else. All SOC displays are showing --.

Hi, We did have a similar issue and then we did enable the battery by changing system type to Storage System. But now the battery is showing but the battery SOC is still not showing anywhere. It is showing as "--" everywhere ... Any idea why?
