1. Solar panel
INSTALLATION EXAMPLES
PREREQUISITES
Solar panel capable of charging a 40–300Ah
service battery. The D250SA uses MPPT
(Maximum Power Point Tracker) to maximise the
power from a solar panel.
TIP 1
Do not connect two solar panels in series. Max.
input voltage 23V.
PREREQUISITES
A dual battery system where the D250SA
charges a 40–300Ah service battery from a
generator which also charges a starter battery.
It is advantageous to use this installation when:
• The alternator is unable to deliver the desired
charging voltage.
TIP 2
If the alternator has external voltage detection
for the service battery, the voltage detection
wiring must be connected to the starter battery.
TIP 3
Complement the D250SA with a
SMARTPASS 120 if the service battery capacity
is greater than 100Ah or has parallel consump-
tion while charging is in progress. This reduces
the charging time.
