Electrical installation instructions with house battery bank, DC to DC

charger, and vehicle alternator if applicable

Once your unit is installed you will need to connect the unit and electrical
system properly.

Components required for a battery bank installation include a DC-to-DC
charger, 100 Amp Breaker or in-line fuse (not recommended), Lithium
Iron batteries, and 4-gauge wire positive and negative for connections
ample length to reach the unit and alternator.

A/  Mount  your  DC-to-DC  charger  and  Lithium  Iron  batteries  in  the
desired  location  securely.  Then  connect  your  positive  and  negative
terminals  to  the  engine  battery  or  alternator  and  run  them  to  the
positive and negative terminals of the DC-to-DC charger.

B/ From the DC-to-DC charger you will run the cables to a breaker. Ideally
that breaker will be 100 Amps to protect that circuit from potential over
voltage.

C/ You will run your wires from your breaker to the Lithium Iron
batteries.
