Hi, i have a 250 ah Lithium , a multiplus compact 800 va , an Orion 30 A monitored with a BMV 702.
I dont have any solar panel on my RV yet.
The problem is according to the bmv , i have 60 % of energy left but the battery is almost at 10 V and the bms is shutting down. I was running a fridge (150W) for 4hours , a router (20W), a few lights(20W), a computer(30W) for an average maximum of 200W. The problem appereared when i started to put the fridge on the 220V inverter to save some propane.
After a few hours , with that fridge on i was on alarm with 10v.
I think there is a problem with the bmv synchonisation but still i dont get it.
Maybe it is because of the way voltage drops with lithium , and the fridge is killing the battery too fast. I dont know.
Maybe i was fooled by the BMV. i will try to charge the battery to 100 % and the SYnc the bmv manually.
if someone sees something that i dont see.
