Hello!
I have a client with two parallel multi II 5000, a variety of MPPT:s with Victron lead carbon batteries monitored through a 500A smartshunt. The system is entirely off grid. About 6000w of installed solar (east, west, south)
The client doesn’t reach float or absorption even though the SOC reaches 100%.
Is this a problem for the calibration of the smartshunt?
Client is worried about the accuracy of SOC.
Thanks.
Id be worried too.
Are you sure 6kWp is enough for 10kVA of inverters? How big is the battery bank, what chemistry? My first guess is that the panels just barely manage to recharge what is being used throughout the day, so the MPPTs will stay in bulk all the time
Id check the settings of both MPPTs and the Shunt, and maybe go over the PV sizing calculation again, just to be sure that the math doesn't go negative
Essentially this situation

Does the system reach target voltage?
Does the system then drop to float voltage?
Ignore soc figures for now if you think they are inaccurate.
Everything can be evaluated using graphing in vrm advanced.
Is DVCC enabled?
