Smart Solar MPPT 150/45 Error 38 and 39

Hi All,

As topic says having error 38 and 39 come up as soon as the panels are reconnected. Checked wiring, battery voltages, shutdown for 3min both battery and panels removed ve.direct cable. Removed all isolators/relays from system and hooked direct to battery with a test set of breakers.

Has been working perfectly, have had no over voltages or spikes, firmware all up to date. Quattro charges no problem at all from Ac Input 1. Had just performed a battery capacity test aswell so voltage has been taken down quite low 42.8v.

System is 51.2V LifePo4. Quattro 8kVa, Venus GX, MPPT 150/45

Thanks Andrew

Hi @Andrew P

Can you please check battery voltage settings in the MPPT?

And is the system online so we can look into it? (if so: what is the VRM id?)
