The C252h 25A Current Sensor Module is one of the Modbus-compatible modules that can be used to measure bidirectional DC currents up to 25A and is ideal for off-grid setups. Using one channel to measure solar current and one channel for load current, it is possible to create a coulomb counting based algorithm to accurately estimate battery capacity.

The current transformers are a bidirectional, hall effect device based on the measuring principle of the hall effect, with a galvanic isolation between primary and secondary circuit. It provides accurate electronic measurement of DC currents in the range of 0—±25. The loop hole size is 8 mm.

It can be configured and controlled by any Modbus RTU master device over RS-485.

The C252h Module can be used for any application in monitoring DC Current, such as:

• Battery Monitoring - Measure charge/discharge current for batteries
• Panel Monitoring - Measure current output of solar panels
• Pump Monitoring - Measure current output of pump VFD
