H1/AC1-G2 parallel set-up guide

This is a summary guide of how to parallel the H1-G2 and AC-G2 inverters. Please refer to the product manual for detailed installation guidance.

1. Define what inverter will be the master inverter (master inverter MUST have the CT/Meter connected to it).
2. Once this has been determined you will need to run a cat 5 (pin 1-8) ethernet lead between the master and 1^st slave inverter.
3. You will need to plug the RS485 plug into parallel 2 on the master inverter and the other end of the RS485 plugs into parallel 1 (follow this process to the next slave inverter).
4. You will need to set the dip switches on the master inverter, please set dip switches 1 and 2 into the on position.
5. Parallel inverter settings will also need to be set on the master inverter and slave inverters.

Inverter parallel settings:

Here you will need to set the “address” and “number”

Enter the menu on the inverter – click on settings – click on parallel

Address – relates to the parallel ID of the machine. You can set between 1-249

For master you set 1, 1^st slave you set as 2, Second slave set as 3… etc

Number – Relates to the amount of inverters in parallel. You can set between 2-8

You must set the same number for all slaves.

things to note:

• All inverters MUST be on the same firmware to eliminate compatibility issues.
• The PV strings and battery storage must be evenly distributed across all inverters.
