DESCRIPTION
The boiler is primarily powered by-
photovoltaic current. If no solar energy
is available, the integrated mains current
reheating function can optionally be used
to heat the water to the set minimum
temperature on the rotary knob.
Via the MC4 contact plugs, a battery can
also be connected. As soon as the connec-
ted battery reaches a voltage of 13.5 V, the
excess energy is used to power the boiler.
This happens while the battery is being
charged.
Via the MC4 contact plugs, a battery can
also be connected. As soon as the connec-
ted battery reaches a voltage of 27 V, the
excess energy is used to power the boiler.
This happens while the battery is being
charged.
