Solis Energy Storage Inverters

For the inverter compatibility list, see FlexiO compatible inverters & charging stations.

Solis Firmware Requirements

IMPORTANT: When using the Solis DataLogger S2-WL-ST (not sold by LIFEPOWR), upgrade the datalogger to firmware version 100.121.CF

Solis inverters give the best curtailment behaviour with the Remote Dispatch interface. Solis added this interface in a firmware update. Without this update, curtailment is not consistent and can fail on some models.

Our recommendation: ask your Solis contact to update every Solis inverter to the latest available firmware, for both the HMI and the DSP. The table below gives the minimum HMI firmware version per model.

Solis Install Instructions

In this section you’ll find instructions on how to integrate FlexiO with Solis Energy Storage Inverters.

This guideline provides instructions for connecting the FlexiObox and configuring FlexiO.
For detailed hardware instructions, see the individual battery and inverter manuals of the manufacturer.

Following inverters are supported by FlexiO:

The Solis RAI inverters are not being sold anymore in Belgium. Lifepowr has also decided not to support any new installations with this Solis RAI inverters.


Solis AI - Disable EMS steering

Solis AI should be disabled on any solis installation with FlexiO. The 2 diffferent Energy Management Systems can not work simultaneously and will cause errors in the FlexiO steering.

Make sure Solis EMS is always OFF
