SDM230 single-phase Modbus Meter for Solax Chargers 100A Direct Connection
Eastron SDM230 single-phase Modbus Meter for Solax Chargers 100A Direct Connection
SDM230 single-phase Modbus Meter for Solax Chargers 100A Direct Connection
Eastron SDM230 Modbus meter — 100 A direct, bi-directional, Modbus — two modules on the rail.
This is the meter SolaX chargers and several of their inverter ranges read the property from. It is a direct-connected 100 A single-phase meter, so the tails pass through it rather than through a CT.
About the Eastron SDM230 Modbus meter
Measurement is bi-directional, which is the point on a PV site: import and export are both recorded, and the meter reports kWh, kvarh, kW, kvar, kVA, power factor, frequency, demand, volts, amps and more over Modbus.
It carries two pulse outputs and a blue backlit LCD, mounts on DIN rail in two modules at 36 mm wide, and measures to Class 1.0 accuracy.
Specified for the SolaX X1, X1-AC, X1-FIT and G4 ranges.
What does this fit?
This is the single-phase Modbus meter a SolaX charger or inverter measures the property with.
100 A direct connection, single phase, for the SolaX X1, X1-AC, X1-FIT and G4 ranges. Direct connection means the tails pass through the meter — there are no CTs.

What the job needs
The details that decide whether this suits the system:
- 100 A direct connection — the tails pass through the meter. There are no CTs.
- Single phase, Class 1.0 accuracy, bi-directional import and export.
- Measures kWh, kvarh, kW, kvar, kVA, power factor, frequency, demand, volts and amps.
- Two pulse outputs, blue backlit LCD, DIN rail mounted, 36 mm wide (2 modules).
- For SolaX X1, X1-AC, X1-FIT and G4 ranges.
- Above 100 A of service, a CT meter is the right part instead.
Where this earns its place
