Luxpower Inverter Configuration (Closed Loop Without LYNK II)

The HELIOS ESS supports closed-loop communication with the Luxpower inverters
listed in the Closed-Loop Communication with Inverters table in the HELIOS ESS Closed-Loop Communication topic.
To enable communication between the inverter and batteries:

Connect a CAT6 or higher straight cable from the HELIOS ESS COM2 port to the
CAN port of the Luxpower inverter-charger.

Luxpower CAN Connection

Configure the Inverter-Charger
1. If using multiple inverters, configure the Luxpower inverters to operate in parallel
  before setting the battery operation parameters.
2. When connecting communication cables for multiple Luxpower inverters that
  operate in parallel, set the CAN communication pins to ON for the first and last
  inverters. For details on connecting multiple inverters in parallel, refer to the inverter
  manual.

Pin Settings for Multiple Luxpower Inverters

Using the inverter touch screen interface, touch the Gear icon to set the properties as indicated in the following tables.
Touch the Up and Down buttons to scroll through screens.
Touch the Set button to save changes on a screen.

NOTE

When the Luxpower inverter is configured in a closed loop with Discover Lithium batteries and the communication breaks between the batteries and inverter, after about a minute, the inverter safely stops operation and displays an alarm. If communication is re-established, the Luxpower inverter resumes closed-loop operation within seconds.
If communication cannot be reestablished and you need to resume operation, you may have to manually convert the Luxpower inverter to an open-loop configuration. For instructions on configuring open loop, refer to Luxpower Inverter Configuration (Open Loop).

NOTE
Depending on your system and particular use case, there may be other settings that require configuration. Refer to the inverter manual for information on these settings.
