K Series parallel set-up guide

This is a summary guide of how to parallel the KH/KA 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 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.

Inverter parallel settings:

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

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

Adress – 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.
