Parallel Installation Guide
Introduction
This inverter can be used in parallel with two different operation modes.
1.
Parallel operation in single phase with up to 6 units.
2.
Maximum 6 units work together to support 3-phase equipment. Four units support one phase maximum.
Package Contents
In parallel kit, you will find the following items in the package:
Parallel communication cable Current sharing cable
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: O-type 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.
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.
