Works: tested and measured on real hardware.

GridZeno reads the inverter and the battery but doesn't control anything yet.

The battery

The state of charge is shown, but SolaX' third generation has no remote control, so the battery runs by the inverter's own settings.

Stop selling at negative prices

Coming later. The dongle can't read the inverter's rated power yet.

Solar and consumption

Requires a meter on the solar inverter you already have.

The serial number starts with XAC: SolaX' third generation, AC-coupled.

The connection

115200 baud.

The battery

The charge level and the power are read in 0x16 and 0x1C. The third generation has no remote control.

Solar and consumption

Only through meter 2 on the solar inverter you already have.

How it differs from its neighbours

• SolaX X1-Fit: The X1-Fit G4 is fourth generation, so the battery can be controlled by the plan.

From the dongle's firmware and our notes on each inverter, not from the datasheet.

Network cable with RJ45 plug. Approx. 25 minutes.

Port

485

Pin

A at pin 4 (485A), B at pin 5 (485B), GND at pin 3 (GND)

Where

On the underside of the inverter, in the bottom row by the earth screw and the BMS port. The energy meter has its own port, Meter, in the top row.
