H3/AC3 parallel set-up guide

This is a summary guide of how to parallel the H3/AC3 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 Chint 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 all dip switches on the master inverter to the on position.
5. Parallel inverter settings will also need to be set on the master inverter and slave inverters.

Master inverter parallel settings:

Enter the menu – click on setting – click on Parallel – select master mode

Slave inverter parallel setting:

Enter the menu – click setting – click Parallel – select Free Mode.

things to note:

If you set the slave to free mode with the can cable is still connected to the master and slave inverters, the slave inverter will revert to being the slave inverter.
