It may not be requested to have a disconnect device in some applications; however, it's still requested to have over-current protection installed. Please refer to typical amperage in the table below as required fuse or breaker size.
WARNING! All wiring must be performed by a qualified personnel.
WARNING! 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 as below.
Recommended Battery Cable Size
| Model | Wire Size | Cable (mm²) | Torque value (max) |
|---|---|---|---|
| 1.0KW 12V | 1 x 6AWG | 14 | 5 Nm |
| 1.5KW 24V | 1 x 6AWG | 14 | 5 Nm |
Steps for Battery Connection:
- Remove insulation sleeve 18 mm for positive and negative conductors.
- Suggest to put bootlace ferrules on the end of positive and negative wires with a proper crimping tool.
- Connect all battery packs as shown in the diagram below.
- Insert the battery wires flatly into the battery connectors of the inverter and make sure the bolts are tightened with a torque of 2 Nm in a clockwise direction. Make sure polarity at both the battery and the inverter/charge is correctly connected and conductors are tightly screwed into the battery terminals. Recommended tool: #2 Pozi Screwdriver.
WARNING: Shock Hazard! Installation must be performed with care due to high battery voltage in series.
CAUTION!! Before making the final DC connection or closing the DC breaker/disconnector, be sure positive (+) must be connected to positive (+) and negative (-) must be connected to negative (-).
