The Solar Charge Controller (Option) - Studer COMPACT - C 1600-12 User's And Installer's Manual

STUDER Innotec COMPACT
4.7.1 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.
4.7.2 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 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.
4.7.3 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 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.

The Solar charge controller (option)

The COMPACT also has a Solar Charge Controller built in. For charging the
batteries, Solar modules can be connected to the screw terminal SOLAR +/-. The in-
built controller is a „Shunt controller" for the maximum input current of 30A for C
1600-12 and C 2600-24 and 20A for C 4000-48. The operating voltage of solar
panels to be connected must match the actual operating voltage of the COMPACT
and never exceeds the max. rated value.
Under no circumstances should any other systems such as wind-generator be
connected at the input of the Solar Charge Controller.
The Solar Charge Controller works automatically and is always in operation. As soon
as the energy is delivered from the Solar Charge Controller, LED 3 "SOLAR
CHARGE" is lit and the batteries are being charged. The Solar Charge Controller
works even when the Battery Charger is functioning. The way of working is the
principally the same as that of the Battery Charger. The function is described in the
section on Battery Charger. The programming and the adjustments are carried out in
accordance with the same conditions. Check with your battery supplier which
adjustments must be carried out for your battery.
