The EA10 DC monitoring system provides the perfect solution for solar string monitoring in combiner and sub-combiner boxes or other DC loads. The modular construction allows easy installation for 8 to 32 strings in a single system. Pulse Reset technology means no output drift and immunity to power spikes and surges up to 20kA.

The EA10HC1AB is the encapsulated communications board (head unit) for the EA10 DC String Monitor. Connect up to four EA10DD08B current sensing modules to one head unit to monitor up to 32 poles (or solar strings). Connect up to 63 head units on one Modbus daisy chain for full system monitoring. 24Vdc to 42Vdc control power needed for each head unit. All boards can be mounted on a standard 35mm DIN rail for easy installation.
