Solar PV charge controllers take the uncertain voltage from a solar panel and condition it to safely charge lead acid batteries. These solar PV charge controllers use pulse width modulation (PWM), and a 3 stage charging method, bulk, absorption, and float (maintenance) charge. They also protect the panels from the batteries after the sun goes down. Solar charge controllers are necessary to protect your PV investment.

The SBC-6112 is the economy version solar PV charge controller. It regulates the power from the solar panels and controls the charge of the batteries. It also cuts out the batteries from the load when the lead acid batteries are depleted to prevent damage to the battery. It has an LED bar readout to show the status of the solar charging system and batteries. The manual for the SBC-6112 solar PV charge controller can be read by clicking on the link below.

The SBC-7112 solar PV charge controller has several features that the SBC6112 controller does not have. It has a liquid crystal panel, which gives more system information, and it has adjustable fill and float charging voltages for the battery charger. The manual for the SBC-7112 solar PV charge regulator can be read by clicking on the link below.

Both solar PV charge controllers have the capability of temperature compensation of the battery charging algorithm with a thermistor that can be put on the battery.

These solar charge controllers also have system functions, for example dusk detection which can be used to turn on the DC output when the sun goes down. They have very low quiescent current draw, which means that when the solar panels are not producing enough power to charge, and when the battery current is not called for, the system can sleep without draining the batteries.
