1St SteP: connect tHe bAtteRy
- Label the battery connection cables as a plus cable (A+) and a minus
cable (A–).
- Lay the battery cables in parallel between the solar charge controller and the
battery.
- Connect the battery connection cable with the correct polarity to the middle pair of
terminals on the solar charge controller (with the battery symbol).
- remove any external 40A fuse in battery connection cable A+.
- Connect battery connection cable A+ with 40A fuse to the Positive pole of
the battery.
- Connect battery connection cable A– to the Negative pole of the battery.
- replace the external fuse in the battery connection cable A+.
- If the connection polarity is correct, the info LeD illuminates green.
2nD SteP: connect tHe SoLAR MoDULe
- ensure that the solar module is protected from incident light.
- ensure that the solar module does not exceed the maximum permissible
input current.
- Label the solar module connection cables as a plus cable (M+) and a minus
cable (M–).
- Lay both solar module connection cables in parallel between the solar module and
the solar charge controller.
- first connect the M+ solar module connection cable to the correct pole of the left
pair of terminals on the solar charge controller (with the solar module symbol), then
connect the M– cable.
- remove the covering from the solar module.
3RD SteP: connect LoADS
notes:
- Deep Discharge Protection (also called Low Voltage Disconnect or
LVD) is only provided for loads < 20A that are connected to the Load
Terminals (5).
- Critical loads like emergency lights, radios, etc. that require un-interrupted power
source are connected directly to the battery through fuse – close to the battery to
protect battery cables against short circuit.
- Loads drawing > 20A should be connected directly to the battery, preferably through
separate Low Voltage Disconnect (LVD). Appropriate fuse should be used close to the
battery to protect battery cables against short circuit.
- other loads drawing < 20A should be connected to the Load Terminals (5) as follows:
- Label the load connection cables as a plus cable (L+) and a minus cable (L–).
- Lay the load connection cables in parallel between the solar charge controller and the load
- first connect the L+ load cable to the correct pole of the right pair of terminals on the solar
