Combination With Other Energy Sources - EFOY Pro 12000 Duo Operation And Installation Manual

4.6.2

Combination with other energy sources

The EFOY Pro can be combined with other energy sources, which then
charge the battery together. The EFOY Pro is often used in combination
with a photovoltaic system.
CAUTION!
The EFOY Pro 12000 Duo needs power to measure the battery voltage as
well as to start.
Take care that the EFOY Pro fuel cell is connected directly to the
batteries and there is no load throw-off in between.
CAUTION!
When connecting a charge controller with temperature compensation
please consider the maximum battery voltage of the EFOY Pro fuel cell
(see chapter 3.3 "Specifications" on page 18).
INFO:
In the case of a combination with other energy sources it is
recommended to adjust the switch-on thresholds of the EFOY Pro so
that the device only switches on if solar alone does not provide enough
energy (e.g. in winter)
