Works: tested and measured on real hardware.

The dongle reads the inverter and never writes anything to it.

What GridZeno reads

Solar production, and grid and consumption when there's an energy meter on the inverter.

Battery

None. The inverter is a grid inverter without a battery, so there's nothing to charge or sell from.

Grid export

SolaX' protocol has no export limit on this inverter, so GridZeno can't stop the sale.

The serial number starts with XST. The dongle reads it like the X1-Mini G4, with three MPPTs.

Export limit

None in SolaX' official maps, and all writes sit behind the password in 0x600.

Rated power

No table in any document, so it isn't read.

How it differs from its neighbours

• SolaX X1-Mini and X1-Boost G4: The X1-Mini and X1-Boost G4 are read the same way, but are connected in the RJ45 port COM/CT.

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

Wires in the inverter's terminal plug. Approx. 30 minutes.

Port

COM/CT (terminal block C)

Pin

A at pin 13 (RS485 A), B at pin 14 (RS485 B), GND at pin 10 (GND)

Where

On the underside of the inverter, by the DONGLE port. The COM/CT connector from the accessory bag has two RJ45 parts, A and B, for energy meter and DRM, and a 20-pin terminal block, C. The dongle goes in the terminal block.
