Note: Cable size quoted is one way from battery to device, however suggested cable size is calculated with return run.
1) Note: If solar panels are wired in Series (increased voltage), then typically 1 x 4mm

cable run per series string
is suitable.
2) Based on 3% voltage drop.
Recommended Fuse Protection
From Alternator Battery
12V Alternator = 70amp Fuse or Circuit Breaker
24V Alternator = 40amp Fuse or Circuit Breaker
*No greater than 20cm from source battery.
PLEASE NOTE: Automatic re-settable circuit breakers are
NOT recommended.
From Solar Panels
Fusing recommended no greater than 20cm from input to DC2DC
24V Charger. Typically 15amps per solar panel (consult your panel
specications for further details).
Primary Battery
Connection
40amp Fuse or Circuit Breaker.
Standard Temperature Sensor Connection
• To install the temperature sensor, simply connect the RJ12 plug from the sensor to the
RJ12 Temperature Sensor Port located next to the Remote Port.
•
On the temperature sensor end, simply connect the ring terminals to the negative terminal
of the main house battery bank.
PLEASE NOTE: For lithium installations, the standard supplied temperature sensor is not
required to be installed for these applications.
