Solution
The charger is not
functioning
The AC input voltage or frequency
is out of range.
Ensure that the input voltage is
between 185 Vac and 265 Vac,
and that the frequency matches
the setting.
The thermal circuit breaker has
tripped.
Reset the 16 A thermal circuit
breaker.
The battery is not
being charged fully.
Incorrect charging current.
Set the charging current at
between 0.1 and 0.2x battery
capacity.
A defective battery connection.
Check the battery terminals.
The absorption voltage has been
set to an incorrect value.
Adjust the absorption voltage to
the correct value.
The float voltage has been set to
an incorrect value.
Adjust the float voltage to the

The internal DC fuse is defective.
Inverter is damaged.
The battery is
overcharged.
The absorption voltage has been
set to an incorrect value.
Adjust the absorption voltage to
the correct value.
The float voltage has been set to

A defective battery.
Replace the battery.
The battery is too small.
Reduce the charging current or
use a battery with a higher
capacity.
The battery is too hot.
Connect a temperature sensor.
Battery charge
current drops to 0
when the absorption
voltage is reached
Alt. 1: Battery overtemperature
(> 50°C)
- Allow battery to cool down
- Place battery in a cool
environment
- Check for shorted cells
Alt 2: Battery temperature sensor
faulty
Unplug battery temperature
sensor from the MultiPlus.
Reset the MultiPlus by switching
it off, then wait for 4 seconds and
switch it on again
If the MultiPlus now charges
normally, the battery temperature
sensor is faulty and needs to be
replaced
