Ample Energy Monitor/Controller II Model H1
The H1 measures voltage, current and temperature for the house bank, voltage for a starter bank, and has an optional auxiliary input for charge current or alternator current (H1/H1A). The auxiliary shunt can be used in the negative lead of solar panels and wind generators to measure their current and accumulate the Amp-hours returned by those charge sources. 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. To control a solar panel, an optional EM-RELAY is required. 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.
The H1 and H1A also has an output signal that can be used as generator start/stop, or as a load disconnect signal. Actuation is based on programmable setpoints. The signal is programmable to operate the generator at specific capacities, for instance "on" at 50% capacity and "off" at 90% capacity. 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. By using the references, batteries can be charged perfectly since the EMON II knows battery state-of-charge, voltage, current and temperature.
