MultiPlus 230V

No output voltage on AC-out-2.

Operating in inverter mode

Connect the inverter/charger to an AC source, and after a 2-minute delay, the AC-out-2 should become live.

Unable to switch over to generator or mains operation.

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

Remove overload or short circuit on AC-out-1 or AC-out-2, and reset the fuse or circuit breaker.

Inverter operation not initiated when switched on

The battery voltage is excessively high or too low. No voltage on DC connection.

Ensure that the battery voltage is within the correct range.

‘Low battery’ LED flashes

The battery voltage is low.

Charge the battery or check the battery connections.

Low battery’ LED lights.

The converter switches off because the battery voltage is too low.

Charge the battery or check the battery connections.

‘Overload’ LED flashes.

The converter load is higher than the nominal load.

Reduce the load.

‘Overload’ LED lights

The converter is switched off due to excessively high load.

Reduce the load.

‘Temperature’ LED flashes or lights.

The environmental temperature is high, or the load is too high.

Install the converter in cool and well-ventilated environment, or reduce the load.

‘Low battery’ and ‘overload’ LEDs flash intermittently.

Low battery voltage and excessively high load.

Charge the batteries, disconnect or reduce the load, or install higher capacity batteries. Fit shorter and/or thicker battery cables.

‘Low battery’ and ‘overload’ LEDs flash simultaneously.

Ripple voltage on the DC connection exceeds 1.5 Vrms.

Check the battery cables and battery connections. Check whether battery capacity is sufficiently high, and increase this if necessary.

‘Low battery’ and ‘overload’ LEDs light.

The inverter is switched off due to an excessively high ripple voltage on the input.

Install batteries with a larger capacity. Fit shorter and/or thicker battery cables, and reset the inverter (switch off, and then on again).

One alarm LED lights and the second flashes.

The inverter is switched off due to alarm activation by the lighted LED. The flashing LED indicates that the inverter was about to switch off due to the related alarm.

Check this table for appropriate measures in regard to this alarm state.

The charger does not operate.

The AC input voltage or frequency is not within the range set.

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

Remove overload or short circuit on AC-out-1 or AC-out-2, and reset fuse/breaker.

The battery fuse has blown.

Replace the battery fuse.

The distortion or the AC input voltage is too large (generally generator supply).

Turn the "Weak AC" and "Dynamic current limiter" settings on.

The charger does not operate.

‘Bulk’ LED flashes and ‘Mains on’ LED illuminates

Charger is in ‘Bulk protection’ mode thus, the maximum bulk charging time of 10 hours is exceeded.

Such a long charging time could indicate a system error (e.g. a battery cell short-circuit).

Check your batteries.

In the standard factory settings the ’Bulk protection’ mode is enabled. The ‘Bulk protection’ mode can be switched off with the help of VEConfigure only.

The battery is not completely charged.

Charging current excessively high, causing premature absorption phase.

Set the charging current to a level between 0.1 and 0.2 times the battery capacity.

Poor battery connection.

Check the battery connections.

The absorption voltage has been set to an incorrect level (too low).

Set the absorption voltage to the correct level.

The float voltage has been set to an incorrect level (too low).

Set the float voltage to the correct level.

The available charging time is too short to fully charge the battery.

Select a longer charging time or higher charging current.

The absorption time is too short. For adaptive charging this can be caused by an extremely high charging current with respect to battery capacity, so that bulk time is insufficient.

Reduce the charging current or select the ‘fixed’ charging characteristics.

The battery is overcharged.

The absorption voltage is set to an incorrect level (too high).

Set the absorption voltage to the correct level.

The float voltage is set to an incorrect level (too high).

Set the float voltage to the correct level.

Poor battery condition.

Replace the battery.

The battery temperature is too high (due to poor ventilation, excessively high environmental temperature, or excessively high charging current).

Improve ventilation, install batteries in a cooler environment, reduce the charging current, and connect the temperature sensor.

The charging current drops to 0 as soon as the absorption phase initiates.

The battery is over-heated (>50°C)

Defective battery temperature sensor

Disconnect the temperature sensor. If charging functions correctly after approximately 1 minute, the temperature sensor should be replaced.

‘Mains on’ flashes and there is no output voltage

The device is in ‘charger only’ operation and mains supply is present. The device rejects the mains supply or is still synchronising.

Bulk and absorption LEDs flash synchronously (simultaneously).

Voltage sense error. The voltage measured at the voltage sense connection deviates too much (more than 7V) from the voltage on the positive and negative connection of the device. There is probably a connection error.

The device will remain in normal operation.

Absorption and float LEDs flash synchronously (simultaneously).

The battery temperature, as measured, has an extremely unlikely value. The sensor is probably defective or has been incorrectly connected. The device will remain in normal operation.
