EasySolar-II GX - Product Manual

Problem

Cause

Solution

No output voltage on AC-out-2, even after waiting.

in inverter mode

AC input is not connecting. Follow steps in MultiPlus generator FAQ.

Unit will not 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 fuse/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'

The battery voltage is low.

Charge the battery or check the battery connections.

'Low battery' (Shutdown)

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

Charge the battery or check the battery connections.

Overload

The converter load is higher than the nominal load.

Reduce the load.

'Overload' (Shutdown)

The converter is switched off due to excessively high load.

Reduce the load.

'Over Temperature'

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 Bat V Overload' (Shutdown)

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.

'High DC Ripple'

Ripple voltage on the DC connection exceeds 1,5Vrms.

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

'DC Ripple Shutdown'

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).

The charger does not operate.

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

Ensure that the AC input is between 185VAC and 265VAC, and that the frequency is within the range set (default setting 45-65 Hz).

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 settings WeakAC and dynamic current limiter on.

The charger does not operate. 'Bulk Protection' shown.

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. 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.

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.

Defective battery temperature sensor

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

The battery is over-heated (+50°C)

Install the battery in a cooler environment

Reduce the charging current

Check whether one of the battery cells has an internal short circuit

1

Device is switched off because one of the other phases in the system has switched off.

Check the failing phase.

3

Not all, or more than, the expected devices were found in the system.

The system is not properly configured. Reconfigure the system. If the error persists, possible communication cable error. Check the cables and switch all equipment off, and then on again.

4

No other device whatsoever detected.

Check the failing unit. Check the communication cables.

5

Overvoltage on AC-out.

Check the AC cables.

10

System time synchronisation problem occurred.

Should not occur in correctly installed equipment. Check the communication cables.

14

Device cannot transmit data.

Check the communication cables (there may be a short circuit).

17

One of the devices has assumed 'master' status because the original master failed.

Check the failing unit. Check the communication cables.

18

Overvoltage has occurred.

Check AC cables.

22

This device cannot function as 'slave'.

This device is an obsolete and unsuitable model. It should be replaced.

24

Switch-over system protection initiated.

Should not occur in correctly installed equipment. Switch all equipment off, and then on again. If the problem recurs, check the installation. Possible solution: increase lower limit of AC input voltage to 210 VAC (factory setting is 180 VAC)

25

Firmware incompatibility. The firmware of one the connected devices is not sufficiently up to date to operate in conjunction with this device.

1) Switch all equipment off. 2) Switch the device returning this error message on. 3) Switch on all other devices one by one until the error message reoccurs. 4) Update the firmware in the last device that was switched on.

26

Internal error.

Should not occur. Switch all equipment off, and then on again. Contact Victron Energy if the problem persists.
