SOLAR PANEL
SITUATION
One alternator and a Solar panel feed-
ing 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. The Solar panel is difficult to
synchronize with the alternator. Due to
these issues, the battery will underper-
form and die prematurely.
INSTALLATION ShEET 4
SOLUTION
The D250S Dual charges the Service
battery quickly and very efficiently
from both the Alternator and the Solar
panel. The Solar panel produces at its
maximum power point when the engine
is off. When both the Solar panel and
the Alternator are on, the Solar panel
adjusts to the Alternator. The battery will
be fully charged, produce more and last
significantly longer.
