Load Regulators
The main function of a charge regulator is to prevent overcharging of the batteries. The charge regulators monitor the battery voltage - when the battery is fully charged, disconnect the charge source (in this case, the solar panels) from the battery until it is needed again. Other small regulators also have the feature that prevents over-discharge of DC loads.
When choosing a home charge controller, you must first evaluate whether the Maximum Power Point Detector, which helps maximize the energy collection of the solar panels, is needed. The charge controller of the Maximum Power Point Detector also has a "voltage reducer", so it can convert high voltages (up to 600 Volts DC) to lower battery voltages (typically 24 or 48 Volt DC) . This allows more modules to be connected in series and using smaller (and less expensive) gauge cables from the modules to the controller. Having a large voltage difference between the solar panel and the battery decreases the efficiency of the charge controller, but the benefits of being able to place the panel farther away from the battery bank, reducing the size of the cables, and having smaller devices that protect Of the overhead, it may be worth it. Load controllers without the Maximum Power Point Detector still hold a large share of the market, but would generally make sense in applications of smaller systems such as boats, lighting, motor homes, and small cabins. Additional information needs to be considered when choosing a regulator, including monitoring requirements, temperature compensation, voltage and current specifications, and panel size to the battery voltage reducer.
