The Intelligent protection against reverse polarity, overcharging, short-circuit, and reverse current. Again we use the same calculation dividing power in watts by the voltage in volts to find amps. Charging your battery at 12 volts and 20 amps will take five hours to charge a 100 amp hour battery. They also have a faster rate of charge. In doing so, it ensures that you maintain optimal power output every moment that your solar panel is in operation. Do NOT let the positive (+) and negative (-) terminals of the battery touch each other. 200 Watt 12 Volt Solar Starter Kit w/ MPPT Charge Controller. Some of Renogys premium starter kits include a battery, making them more reliable kits for homes. This is due to the special ability of the MPPT controller to lower the voltage to the battery bank voltage and then increase the current to make up for lost power. Charging cycles are slower on cloudy days. Therefore, an oversized solar array will not operate at peak power. A grid-tied system simply means the solar installation connects to the electrical grid. Charge controllers are sized depending on your solar array's current and the solar systems voltage. But by doing some simple math, properly calculating your energy needs, and learning a bit about the different battery options available to you, youll be well on your way to a battery bank to fit you and your households needs. Charge controllers also prevent your batteries from being overcharged by reducing the flow of energy to the battery once it reaches a specific voltage. After connecting the battery to the charge controller, the controller will turn on automatically. Lets say you have 4 x 100 Watt panels in series, each with an open-circuit voltage of 22.5V.
