lit. The inverter is switched off and the battery charger switched on. This process is automatic, unless the charger mode or the transfer mode is disabled (see Chap. 5.5).
The maximum current of the Transfer switch is 16A. That means through this system, consuming devices up to a maximum of al 3700 Watt can be operated. When the Battery Charger is working, part of this power is used for charging according to the power sharing system.
The Transfer system is protected against overload with a circuit breaker on the AC Input side of the XP-COMPACT. If the system has been overloaded, the button/pin of the fuse will pop out. To put the automatic safety system back in to operating you must push this pin back.
Note: in the Inverter operation, The XP-COMPACT generates a true sinusoidal and quartz stabilized output voltage. However if the XP-COMPACT is supplied from a grid or a generator and the transfer contact is active, then you have at the output AC OUT the same voltage as that at the input. This voltage can not be modified by the XP-
COMPACT !
4.8.1 Set the transfer voltage threshold
The voltage threshold of the transfer can be adjusted between 150 to 230V with the turning knobs (23). From factory this value is 200V. Most appliances can work on this voltage. When the Input voltages reach the selected value on turning knob, the inverter switches off and the AC INPUT goes directly on the AC OUTPUT. When the voltage INPUT is less of 20V the value set, the transfer is stopped and the OUTPUT switches back on the inverter.
Note : Don’t use the turning knobs “TRANSFER” (23) to adjust the AC OUTPUT voltage ! This is only it’s only a voltage threshold level to enable or disable the transfer.
4.8.2 FAST (UPS)- MODE for the Transfer Switch
The quick and break free Transfer mode is programmed with a slide switch „Transfer De-lay“ OFF, which is on the front side (cable connections side).
The aim of the XP-COMPACT is to supply the appliance with a break-free alternating volt-age. When the incoming voltage AC IN no longer matches values which have been set with the Turning Knob 23, the inverter switches on at once. The transfer is carried out in 0.02 seconds. This quick transfer ensures a break-free function for most appliances. If you have an alternating voltage back at the input AC IN, transfer system starts up again with-out any break, and the inverter is stopped.
4.8.3 Delayed mode of the Transfer System
The delayed mode of the transfer system „Transfer Delay ON“ is programmed with the slide switch on front with the cable connections. The XP-COMPACT provides a break-free alternating voltage for the appliance. A quick transfer switch is not always sensitive nor is it always desired. For example, when the appliances are operated by a small back-up generator. An overload of a short period on such a generator, i.e. start of a vacuum cleaner etc., has the effect of decreasing the voltage for a short time. As in such cases the transfer to the Inverter is not desired, the transfer system can be programmed with a delay. When the slide switch (Transfer delay) is in the „On“ position, the transfer to the inverter takes place with a delay of 5 seconds. If the voltage falls below 100Vac, the transfer takes place without delay ! The transfer switching to the Inverter takes place without any break.
