3. TROUBLE SHOOTING TABLE
Proceed as follows for quick detection of common faults.
DC loads must be disconnected from the batteries and the AC loads must be disconnected
from the inverter before the inverter and/ or battery charger is tested.
Consult your Victron Energy dealer if the fault cannot be resolved.

Solution
Ensure that the battery voltage
is within the correct value.
Charge the battery or check the
battery connections.
Charge the battery or check the
battery connections.
reduce the load.
reduce the load.
Place the inverter in a cool and
well-ventilated room, or reduce
the load.
Charge the batteries, reduce
the load or install batteries with
a higher capacity. Use shorter
and/ or thicker battery cables.
Check the battery cables and
terminals.
Check the battery capacity;
increase if necessary.
Install batteries with a higher
capacity. Use shorter and/ or
thicker battery cables and reset
the inverter (switch off and on
again).
Check the table for the
appropriate course of action.
