Mounting the Unit
When installing multiple units, please follow below chart.
Note: For proper air circulation to dissipate heat, allow a clearance of approx. 20cm to the side and approx. 50 cm
above and below the unit. Be sure to install each unit in the same level.
Wiring Connection
The cable size of each inverter is shown as below:
Recommended battery cable and terminal size for each inverter: Ring terminal:
WARNING: Be sure the length of all battery cables is the same. Otherwise, there will be voltage difference between
inverter and battery to cause parallel inverters not working.
Recommended AC input and output cable size for each inverter:
You need to connect the cables of each inverter together. Take the battery cables for example: You need to use a
connector or bus-bar as a joint to connect the battery cables together, and then connect to the battery terminal.
The cable size used from joint to battery should be X times cable size in the tables above. “X” indicates the number
of inverters connected in parallel.
Regarding AC input and output, please also follow the same principle.
CAUTION!! Please install the breaker at the battery and AC input side. This will ensure the inverter can be
securely disconnected during maintenance and fully protected from over current of battery or AC input.
