NOTE
1. Install a DC circuit breaker between the inverter and the battery before connecting the
lead-acid battery. If lithium batteries are used, turn them off first.
2. Before the battery is connected with the inverter for first time, check the battery for the
battery type acceptable to the inverter and its charging voltage, charging current, end-off
voltage and other important parameters, which affect the battery life.
Procedure
：
1.
Check that battery polarity and voltage are normal and that the battery voltage is within the
allowable range specified in the inverter specifications (42V-58V).
2.
The battery terminals are included in the package. Strip off 5mm insulation layer of the
battery cable and route it through the waterproof cover and waterproof terminal as shown
in Fig. 6.1.1:
Fig. 6.1.1
3.
Fix the waterproof terminal on the waterproof cover. In Fig.6.1.1, route 2 through the
waterproof cover, screw with 1, and reinstall the waterproof cap 3 onto 2.
4.
Connect the battery cable section from which the insulation layer is stripped with the battery
terminal (accessory), as shown in Fig. 6.1.2, route the cable through the cable inlet at the
terminal tail, and bind up the terminal tail by an insulated rubber tape or a thermoplastics
pipe after tightening. During installation, properly complete insulation treatment, otherwise
it is possible to cause the battery short circuit.
