The H1A accepts the signal from an Alternator Current Sensor and displays alternator Amps. The H1 provides an output signal that is used to control a solar panel disconnect relay, and to lock the Next Step Regulator into the absorption mode until the batteries are full. This assembly is a Form-C relay capable of 30 Amps. Since it is a Form-C contact, the solar panels can be diverted to an alternate load when not charging the batteries. Relay actuation is based on programmable setpoints.
Actuation is based on programmable setpoints.
The signal can also be used as a load disconnect output by programming the on and off capacities as desired. An optional Load Disconnect Relay is required to disconnect loads. In addition, the H1 and H1A provide remote charge references to interface to the Smart Alternator Regulator. The H2 measures voltage, current and temperature for two house banks. It does not have the solar panel control, or remote charge references.
