System: I have 3 SmartSolar MPPT 100/30's connected individually to (3) 335W panels. They are networked together with a BMV-712 and connected to an 800ah LFP battery, with smartsolar battery setting on LFP. I just switched my battery bank to lithium from AGM, but I had the same issue with the AGMs. In the past, my shore charger was mostly charging the bank, but now I need to switch to solar and Multiplus as I will be leaving the dock soon.
Problem: Only one of the chargers is producing significant wattage (264W currently), and it seems to be charging the battery, although network total power shows 0. The other 2 chargers flicker some wattage and then back off to 0. It seems like the master controller is telling the slave controllers to not charge. In the smartsolar history, one can see that the all the chargers are working as they each have history on some past days of significant charging. I need all of the chargers to work together to charge the lithiums which are currently at 13.18v. Another anomaly is that 1 hour ago I was showing total network power of 255W. I removed each controller and the BMV from the VE network to try to reset it and then rejoined them all, BMV first. Now, total network power shows 0W, but the BMV shows positive wattage (175W) going into the batteries. Mostly, I need the chargers to all work together, instead of just 1 at a time, to bulk up the lithiums during the day. It seems like synching between controllers and the app may have glitches that prevent synchronized charging and also an issue with showing total network power.
On a sunny day this system should be pushing 900W plus into the batteries. Any suggestions?
