Set the INPUT LIMIT (P-03)

The current available to the Invertek depends on the source of the AC input supply,

i.e. motor generator, limited grid supply in a caravan park or shore power. The

value of the “INPUT LIMIT” P-03 adjustment must be lower or equal to the current

available from the AC Input source. For example if you have a generator of 2kW

you must adjust the “Input limit” to approximately 8.5A. To calculate this, divide the

nominal power of the AC input source (2000W) by the voltage (230V). If the circuit

breaker before the Invertek is lower than this value, then you must set the “Input

Limit” to the value of the circuit breaker.

Generator power Current (230V)

500W 2A

900W 4A

1500W 6,5A

2000W 8,5A

3000W 13A

G.1.4 Set the charging current (P-02):

The maximum charging current or the battery can be adjusted the Parameters P-02

. The charging current should be set to approximately 10-15% of the battery

capacity (at C10). This means that the charging current for a battery with 300Ah

should be set between 30-45A. The charging current is displayed on the

“multi-display” or “CURRENT MONITOR” on the front panel

G.1.5 Battery Condition:

The built in microprocessor features a specially developed algorithm (formulae)

which calculates the actual state of charge (SOC) of the battery and displays it on

LED-8. The Equalize LED-7 is lit when the system is performing an equalization

charge. The SOC displayed should be used as a guide only, for batteries which

are not sealed, use a hydrometer to determine the exact SOC.

For Safety reasons. You must get the recommended charge voltage and charge

current from your battery supplier. The voltage levels and charge characteristics

can be changed through “Parameters P-12,P-13,P-14,P-15 and P-16”. The correct

charging levels are critical for safe functioning and long life of the battery.
