Ok, I’m perplexed. I have had system set up for awhile without any real power draws but lately I have been using it regularly on my off grid property. System is 180 amp lifepo4 battery with 60 amp cells in 4s3p configuration. I’m using a Daly 4S 100 amp BMS with a separate port for charging. I’m charging with a Rich Solar 40 amp MPPT with 4-100 watt panels. Max load is about 100 watts out of a 400 watt inverter.
lt seems like the charging port on the BMS is turning off and then not turning back on. This causes the battery to completely drain since nothing is going in. It has done this a few times but until today just unhooking the load got it working again. Today I actually had to charge the battery through the common port until the voltage came up enough and then the charging port started working.
It just seems like a faulty charging port on my BMS. I know I could bypass it and charge directly according to Will. But is there something else I should be aware of? Is there other reasons why the charging port would just stop working?.
