4.3 Battery Connection
Before connecting to a battery, please install a separate DC breaker (120A) between the inverter and the 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 an electric arc occurs when connecting a battery to the inverter without the use of a DC breaker.
●
It's very important for system safety and efficient operation to use an appropriate cable for the battery connection. To reduce the
risk of injury, please use the correct recommended cable size. Refer to Figure 4.3-1.
●
●
Suggestion: The battery should be installed with the correct distance between each battery unit, for details please refer to the
battery manufacturer's user manual.
●
The number of battery cells used will be determined by the customer depending on the required capacity, however the choice will
be limited to a total series voltage array of 48 V.
Please follow the steps below to implement battery connection:
(
1
)
Check the nominal voltage of batteries. The nominal output voltage should meet Zeus Appollo Solar product Spec.
(
2
)
Disconnect DC breaker between the inverter and the battery.
(
3
)
Disconnect the screw cap from the insulator.
(
4
)
Disconnect the waterproof ring from the 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 using an appropriate tool and screw down the screw cap slightly. Refer to Figure 4.3-3, Figure 4.3-4.
(
7
)
Insert the battery terminals into the corresponding apertures and fasten them with a screwdriver and a spanner, then fasten the
battery cover with the pan head screws provided in the accessory bag. Refer to Figure 4.3-5, Figure 4.3-6, Figure 4.3-7.
(
8
)
Screw down the screw cap again.
(
9
)
An earth wire terminal is set on the left side of the inverter. If necessary, it can be connected to earth wire. Refer to Figure
