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 EA10DD08B is an encapsulated DC current sensing board. Each EA10DD08B can monitor eight channels (or solar strings) with a current range of 0.1A to 20A (+20% over) per channel. Four current sensing modules can connect serially to one EA10HC1AB communication board (head unit) for a total of 32 monitoring nodes. All boards can be mounted on a standard 35mm DIN rail for easy installation.
