4.4 Parallel Operation
The APSWX4KP48VMPPT and APSWX6KP48VMPPT support up to nine parallel Inverter/Chargers in a single-phase or
3-Phase configuration.
4.4.1 Single-Phase Parallel Configuration
1. The Inverter/Charger should never share the same solar panel group that is connected to other sources.
2. Connect the parallel communication cables first for line and power.
3. Set the parameters for each Inverter/Charger separately.
Warning! When working in parallel modes, the settings must be the same on every Inverter/Charger.
4. Once the parameters are set, turn each inverter ON.
Warning! Each group of PV modules can only be used by one inverter. Otherwise, it may damage the other
inverters.
