4.6.3 Input current repartition (Power sharing)

To manage the power available on the AC INPUT (depends on the supply use) the HP- COMPACT is equipped with a system usually called “Power sharing” or INPUT power dis- tribution. With this function it is possible to limit the AC INPUT current assigned to the charger. The more current it uses on the OUTPUT the less it gives to the charger. Priority to the OUTPUT. When the power sharing is used the LED 200% (red) is lit to point out that the charge is limited.

Caution: if the power use on the OUTPUT is higher than the value of the INPUT LIMIT (26) the HP-COMPACT cannot limit the current, then the generator means to stop or the circuit breaker means to break before.

4.6.3.1 Set the INPUT LIMIT (26)
The current available for the HP-COMPACT depends on the	Generator	Current
supply used from a motor generator, the network of a camp-	power	(230V)
ing or of a shore connection. The value of the turning knobs	500W	2A
INPUT LIMIT (26) must be adjusted lower or equal to the cur-	900W	4A
rent available from the source.	1500W	6.5A
For example if you have a generator of 2kW you must adjust
	2000W	8.5A
the turning knobs 26 to a max. 8.5A. To calculate this, one
	3000W	13A
divides the nominal power (2000W) by the voltage (230V). If
	5000W	21A

you have a circuit breaker (i.e. 6A) before the HP-COMPACT, then you set this value on the turning knobs (26) (i.e. 6A).

This adjustment can be done remotely with the optional RPS-01 (see section 3.6.7). In that case the smallest values will be taken into account.

4.6.4 Charging current

The maximum charging current for the battery can be adjusted with the Turning Knob 22 (CHARGER). The charging current of the battery should be set to approximately 10 – 20% of the battery capacity (at C10). This means that the charging current for a battery with 300Ah should be set between 30 – 60A.

The charging current is displayed on POWER MONITOR (25) of the front panel or on the Remote Control.

4.6.5 Battery Condition

Built-in microprocessor with a specially developed algorithm calculates the actual state of charge of the battery and displays it on LED 15 – 18. The LED 14 is lit when the system is carrying out a charge cycle with equalization.

Notice: the exact measure of the battery state of charge with electrical parameters is al- most impossible. The display of the state of charge is always more or less precise. The measure system built in the HP-COMPACT takes into account the battery voltage, the dis- charge and charge current as well as the undulation of the voltage. If the battery and the HP-COMPACT are used according to their technical data, the battery state of charge is displaid accurately. In the following cases of use the display can diverge:
