13. Error Indications

With the procedures below, most errors can be quickly identified. If an error cannot be resolved, please refer to your Victron Ener-
gy supplier.

'Low battery' The battery voltage is low.
'Low battery' (Shutdown) The converter switches off because the battery voltage is too
low.
'Overload' The converter load is higher than the nominal load.
'Overload' (Shutdown) The converter is switched off due to excessively high load.
'Over Temperature' The environmental temperature is high, or the load is too high.

'High DC Ripple' Ripple voltage on the DC connection exceeds 1,5Vrms.
'DC Ripple Shutdown' The inverter is switched off due to an excessively high ripple

Circuit breaker or fuse in the AC-in input is open as a result of
overload.
The battery fuse has blown.

indicate a system error (e.g. a battery cell short-circuit).
The battery is not complete- Charging current excessively high, causing premature absorp-
ly charged. tion phase.
Poor battery connection.
The absorption voltage has been set to an incorrect level (too
low).
The float voltage has been set to an incorrect level (too low).
The available charging time is too short to fully charge the bat-
tery.
The absorption time is too short. For adaptive charging this
can be caused by an extremely high charging current with re-
spect to battery capacity, so that bulk time is insufficient.
The battery is overcharged. The absorption voltage is set to an incorrect level (too high).
Poor battery connection.
The float voltage is set to an incorrect level (too high).
Poor battery condition.
The battery temperature is too high (due to poor ventilation,
excessively high environmental temperature, or excessively
high charging current).
The charging current drops Defective battery temperature sensor
to 0 as soon as the absorp-
tion phase initiates.
The battery is over-heated (+50°C)

Cause
Remove overload or short circuit on AC-out-1 or AC-out-2, and
reset fuse/breaker.
Ensure that the battery voltage is within the correct range.
Charge the battery or check the battery connections.
Charge the battery or check the battery connections.
Reduce the load.
Reduce the load.
Install the converter in cool and well-ventilated environment, or
reduce the load.
Charge the batteries, disconnect or reduce the load, or install
higher capacity batteries. Fit shorter and/or thicker battery ca-
bles.
Check the battery cables and battery connections. Check
whether battery capacity is sufficiently high, and increase this if
necessary.
Install batteries with a larger capacity. Fit shorter and/or thicker
battery cables, and reset the inverter (switch off, and then on
again).
Ensure that the AC input is between 185VAC and 265VAC,
and that the frequency is within the range set (default setting
45-65 Hz).
Remove overload or short circuit on AC-out-1 or AC-out-2, and
reset fuse/breaker.
Replace the battery fuse.
Turn the settings WeakAC and dynamic current limiter on.
Check your batteries. NOTE: You can reset the error mode by
switching off and back on the . The standard factory setting of
the 'Bulk protection' mode is switched on. The 'Bulk protection'
mode can be switched off with help of VEConfigure only.
Set the charging current to a level between 0.1 and 0.2 times
the battery capacity.
Check the battery connections.
Set the absorption voltage to the correct level.
Set the float voltage to the correct level.
Select a longer charging time or higher charging current.
Reduce the charging current or select the 'fixed' charging char-
acteristics.
Set the absorption voltage to the correct level.
Check the battery connections.
Set the float voltage to the correct level.
Replace the battery.
Improve ventilation, install batteries in a cooler environment,
reduce the charging current, and connect the temperature
sensor.
Disconnect the temperature sensor plug in the . If charging
functions correctly after approximately 1 minute, the tempera-
ture sensor should be replaced.
Install the battery in a cooler environment
Reduce the charging current
Check whether one of the battery cells has an internal short
circuit
