The solar charge controller (optional)

With the built-in solar charge controller, the XP-COMPACT is a complete solar-power-center. In a
solar installation this controller ensures that the batteries are charged correctly. With the XP-
COMPACT, batteries can be charged with a generator and with the solar modules at the same
time. The charging of batteries with both energy sources is carried out fully automatically.
2.2.5

Remote control

As an option, a remote control can be connected to XP-COMPACT. Extra display and program-
ming possibilities are available on the remote control (see Chap.5). The remote control is supplied
with a 20m long cable. This cable can go to 40m long. On the remote control output power and
charging current are also monitored.

2.3 Battery connections

Lead-acid batteries are normally available in blocks of 2V, 6V or 12V. In most cases, to generate
the necessary operating voltage and the capacity of the batteries for the XP-COMPACT many bat-
teries have to be connected together in parallel and or in series. Following three examples are
shown:
