4.3 Battery Connection
Before connecting to battery, please install a separate DC breaker (60A for Replus 3648ME and 120A for
) between
inverter and battery. This will ensure the inverter can be securely disconnected during maintenance.
●
Be aware of electric shock and chemical hazards!
●
It is a normal phenomenon that electric arc occurs when connecting battery to the inverter without use a DC breaker.
●
It's very important for system safety and efficient operation to use appropriate cable for battery connection. To reduce risk of
injury, please use the proper recommended cable size. Refer to Figure 4.3-1.

Suggestion: Batteries
must be installed with a distance to each other, details please refer to battery manufacture's user manual.
●
As
for the number of cells used, it will be decided by customer's choice, the choice must
comply with the followed requirement:
the rated voltage is 48V.
Please follow below steps to implement battery connection:
(
1
)
Check the nominal voltage of batteries. The nominal output voltage should meet ReneSola product Spec.
(
2
)
Disconnect DC breaker between inverter and battery.
(
3
)
Disconnect screw cap from insulator.
(
4
)
Disconnect waterproof ring from insulator.
(
5
)
Put the cable through the components in this order: screw cap, waterproof ring, insulator, battery cover and battery terminal.
Refer to Figure 4.3-2.
(
6
)
Compress the terminal head by professional tool and screw down screw cap slight. Refer to Figure 4.3-3, Figure 4.3-4.
(
7
)
Put battery terminals into the corresponding holes and fasten them by screwdriver and spanner
(
recommended torsion:50~70Kg-
f.cm), then fasten battery cover with pan head screws in accessory bag. Refer to Figure 4.3-5, Figure 4.3-6, Figure 4.3-7.
(
8
)
Screw down screw cap again.
