Contador de energia monofásico Solplanet SDM230 com Modbus RTU, medição direta 100A, montagem em calha DIN

Single-phase energy meter engineered for precise monitoring of Solplanet inverter systems. Directly measures up to 100A with Class 1 accuracy, delivering real-time data on voltage, current, power, and energy via Modbus RTU over RS485. The backlit LCD and DIN rail mounting make it a practical addition to any solar installation.

Advantages

Self-supplied power eliminates the need for an external source, while the 3000% overload capacity ensures resilience against current spikes. The IP51 front protection guards against dust and moisture, and the 2-year warranty provides long-term reliability.
