We are attempting to charge a (non-Victron) 24V LFP Lithium battery after the BMS has turned off the battery due to deep discharge with a SmartSolar 100/30 and 1 solar panel (385Wp, 35 Vmp). There is no voltage to be measured on the poles of the battery. We also have a Victron battery monitor connected. We observe that the monitor keeps turning on, voltage going up to some 15V, the going down again and turning off again, this process takes a few seconds, after another few seconds the process repeats. This process continues and the MPPT seems to not be able to charge the battery. In one test where we had connected two panels in series it worked after a couple of minutes. Is there a way to get this to work with one panel, I am assuming with two panels the voltage ramps up quickly enough for the BMS to realize that there is a charger attempting to charge, however this is just an assumption. Does anyone have some insights or tips how to deal with this? In practice we expect this to not happen very often but when it happens its a big issue as one has to connect an alternative charging source to the battery in order to bring it back to life. Any support is greatly appreciated.
