Hello,
I'm using a Victron MPPT 75/15 with three 100W panels and a 100AH lithium battery. I've checked all wires and fuses multiple times, and everything appears to be in order. However, I'm experiencing fluctuations in the MPPT voltage, and I can't seem to get more than 0 to 0.1A output. To confirm, I tested the battery with a 10A lithium charger, and it charges properly and swiftly through different stages. I let the battery rest until it reached 13.33V, then retested it with the solar setup and MPPT, yet encountered the same output issue. I've used two different multimeters to test every wire, and the voltage is accurate across the battery, wires, and MPPT port. Despite this, the MPPT doesn't seem to register current or charge the battery. Could the BMS be blocking due to low current? Is it normal? I have attached a video of the mppt screen. Thank you for your assistance.
