The La Marche Solar Charge Controller is available in two models, the SCM (Solar Charge Controller – MPPT Technology) and SCP (Solar Charge Controller – PWM Technology). Both models regulate the voltage and current from the solar modules to properly charge the battery and supply the load. In order to maximize the power that can be extracted from the solar modules, the SCM Controller utilizes Maximum Power Point Tracking (MPPT) algorithm. For a simplified version, the SCP controller regulates the charging power using Pulse Width Modulation (PWM).
The Solar Charge Controller is available in 10A and 20A versions with 12/24V auto-select output. Both controller models feature built-in protection for solar modules, batteries and load connections. Additional features include Low Voltage Load Disconnect, Status LEDs, USB connection for diagnostic parameters and an extra set of output terminals for additional loads.
