INSTALLATION SHEET 1 INSTALLATION SHEET 2
SITUATION
Solar panel.
PROBLEM
A solar panel with 36 cells
produces maximum power at
about 17V. Many regulator
reduce the voltage by “bur-
ning off” energy.
SOLUTION
The D250S DUAL searches for
the Maximum Power Point and
charges the battery perfectly
with very high efficiency.
TIP 1
Mount the temperature sensor
on the Service battery.
Boat: All installation should
be done in accordance with
ISO10133.
SITUATION
Onealternatorfeedinga
Starter battery and a small
Service battery.
PROBLEM
The Service battery will take a
very long time to recharge due
to low alternator voltage. Due
to this, the battery will under-
perform and die prematurely.
SOLUTION
The D250S DUAL charges the
Service battery quickly and
very efficiently. The battery
will be fully charged, produce
more and last significantly
longer.
TIP 2
Refer to Tip 1.
Alternators with voltage sensor
cables should connect this on
the Starter battery
3. Caravan/trailer: For
13-pole contact, connect
D250S DUAL alternator bat-
tery + to pin #9. Connect pin
#13 to D250S DUAL vehicle
