HQST 10 Amp PWM Duo Battery Charge Controller applied Pulse Width Modulation (PWM) technology to help regulate the power from your solar panel to battery. This duo battery solar regulator adopts the most advanced digital techniques and operates fully automatically.This PWM charge controller features duo battery charging capability making it great for RVs, caravans, and boats. With its advanced PWM charging technology, your batteries will be protected from discharging and over-charging. The PWM battery charging can greatly increase the lifetime of your battery and has various unique functions and quite easy to use features.

The main advantage of Pulse Width Modulation (PWM) is that power loss in the switching devices is very low. When a switch is off, there is practically no current. When the device is on, there is almost no voltage drop across the switch. Power loss, being the product of voltage and current, is thus in both cases close to zero. PWM also works well with digital controls, which, because of their on/off nature, can easily set to the needed duty cycle.

The Controller is Negative Grounding.

You can add a HQST Tracer Meter MT-1 to easily monitor your solar energy system. If you want to add a tracer meter, both batteries must be connected to the charge controller, otherwise there will be a default error.
