1. Disconnect the starter battery from the circuit
2. Double check the alternator voltage does not
exceed 16.5V.

The panel is producing voltage higher than the
25V operating voltage of the DC-DC MPPT.

1.
Contact support if overvoltage condition continues
and the operating voltage is under 24.5V
3.
Double check your connections and make sure
you’re not exceeding 25.5Volts open. Use a
multimeter to measure the panel leads and
confirm not over voltage.

1. Disconnect the starter battery from the circuit
2.
Check on the alternator charging rating to
ensure not over the 30A|50A limit.

Your battery poles are reversed.
2.
1.
Fix the connection to continue normal operation.
4.
Assuming correct polarity from the Multimeter,
negative readings on the multi-meter indicate
reverse polarity.
3.
Fix the connection to resume normal working
mode. Use a multi-meter to measure the correct
polarity before connecting to the DC-DC MPPT
and ensure proper connection.
