Solar System

Simplicity - AT9312111

Drawing AT9312111 shows how simply a remote solar system can be assembled using the Energy Monitor II, H1. Solar panels charge the house bank under control of the EMON II. The solar panels are controlled by a relay that connects and disconnects the solar panels according to limits programmed into the EMON II.

Load Control

The EMON II also controls load devices, disconnecting and connecting them at programmed capacity limits. For instance, an irrigation pump can be turned off at a selected low capacity remaining and back on again when the battery capacity returns to a selected value.

Temperature Compensation

Since the EMON II is fully programmable, and includes temperature compensation for voltage and battery capacity, a superior control system results. Normal solar panels controllers and load disconnect devices sense voltage only, not capacity. They normally don't have temperature compensation either.
