PV charging not working on ESS system

Hi guys,

Not sure what's happening but the PV charging has stopped working for some time now. ESS system works extremely well but somehow PV is not there. The voltage is correct but the current doesn't reach MPPT.

There are no errors or any indication of the issue. I understand its winter in the UK but even when its sunny I always have at least 10W from solar. Now its total 0.

Any ideas where to look?

Found it... MPPT got the temperature set to 6 degrees below which MPPT stopped working/ charging.
