Hi all,

I'm a complete newbie here. I have absolutely no clue whatsoever. I have had 10 solar panels installed with Sunsynk inverter and batteries (5KW). Since it was installed I have been monitoring it and the MPPT2 (not sure what this is) is showing 0W consistently. Is it not supposed to show something as well?

Many thanks,
S

It means nothing is connected to MPPT2, the panels were connected as a single string to MPPT1. This leaves expansion at a later date.

Just a sanity check. What type of panels do you have connected to that 5kW Sunsynk inverter? To have 10 panels on only 1 MPPT sounds like a lot, but may be not if it's smaller-output panels. What readings for Watts and Volts are you seeing on the screen for MPPT1?

Hi,

I'm not really sure. I'll attach the screenshots showing readings and type of panels here:

Datasheet for those shows:
