I’ve just fitted a 75/15 to my boat. It’s a 24 v system. I have two 150W panels in series. I’ve triple checked the polarity. The green and yellow Leds are flashing and it’s not charging. I’ve tried disconnecting both pv panels then the battery And re connecting. No difference. The panels are putting in about 45 volts. I have 24 V at the battery and on the battery connectioon on the MPPT, hoping for some help please?
Mppt manual, led status.
Charger or panel overvoltage??
Disconnect the PV first, then the battery.
Connect the battery first, then the PV panels.
Is your Mppt a smart version?
I’ve tried that. It is a smart one but I’ve not managed to connect, it wants to pair with the phone and asks me to enter the number on the MPPT but I’ve not found the right number yet.
The default PIN is 000000 (six zero) and you have to use VictronConnect..
OK I tried again, I found the right code, it connects, the firmware updated. I tried disconnecting the pv panels again then the battery, then waited 10 mins, re connected. Just the same .
