4.10 PARALLELING INFORMATION
4.10.1 PARALLEL COMMUNICATION CONNECTIONS
The EG4 6000XP inverter supports parallel connections to expand power and energy capacity to suit
different usage scenarios. Up to 16 units can be paralleled to reach a capacity of up to 96kW. The
parallel communication wiring diagrams are shown below. The manual bypass switch connects the
loads to LOAD panel as default. If the inverters fail, users can switch the loads to utility.
Remember!
Put the CAN communication PIN to ON status for the first and the last inverter and OFF for
inverters in between.
Note: Both switches in the “ON” position translates to address 1. Both switches in the “OFF” position
translates to address 0.
Please contact your inverter supplier for more detailed guidance on paralleling systems.
4.10.2 PARALLEL CONFIGURATION
Important notices for parallel system:
• If utilizing the Generator input (GEN), ensure that the generator is connected to all inverters in
parallel.
• If not possible to evenly divide solar strings per inverter, it is recommended to have more PV
strings on the master inverter.
• The values shown on the LCD of each inverter displays the individual inverter’s contribution to
the system, not the system’s total.
Before commissioning:
1. Verify that all inverters in the system are updated to the latest firmware. Please contact your
distributor to confirm you have the latest version.
2. Make sure the power cables and parallel communications cables have been wired correctly, and
verify the DIP-switch settings are correct.
3. Ensure your LOAD breakers are off (open). Ensure there is no AC voltage present with a
multimeter before proceeding to the next step.
4. Power on the inverters.
5. Navigate to setting 21 to configure phasing.
6. Starting with the inverter with battery to inverter communication cable connected, change setting
21 to 1PH for split-phase parallel. The LCD will then switch to a secondary setting, Parallel
Phase. Set the inverter to P1 for phase 1. Repeat this step for all paralleled inverters.
7. Enable “Battery Shared” on all inverters in parallel.
