1.What is a solar charge controller?
1)A charge controller, also known as regulator, is an integral part of most solar systems over 15 watts. 2)The 42 Amp Charge Controller will prevent solar panels of 500 watts or less from overcharging your battery. 3)Solar panel connects to charge controller then to your 12V battery unit or 12VDC appliance. 4)For AC appliances or different voltages, need to buy separate inverter or adaptors! 2. What is MPPT? Intelligent Chip - Squeeze 30% more juice out of PV!!
possible. In colder temperature, panel produces more power. The conventional charge controller can not deliver this extra power to the battery. If using a MPPT charge controller in a system, the PV module can generate more power by neglecting battery voltage, and it can deliver the maximum power. Typically, in the MPPT charge controller, the generated voltage step down, and at the same time current step up at the same ratio. The MPPT regulators are useful in the winter months, in the cloudy or hazy days or when the battery is deeply discharged. 3.Features:1) For solar panels generating up to 500W/42A of current (12V)Suited for solar panels up to a maximum of 500 watts2) Intelligent MPPT charge control ensures batteries reach max capacity!Idled PV power, temperature of the battery will be monitored by the microprocessor!Squeeze every juicy out of PV,converted to different voltages or amps to charge up the battery!With this device, you can charge a 12V battery from a higher voltage PV panel. 3)LED Digital display - Indicate battery's voltage and charging current.When Red Float LED light is on - The battery reached it's factory pre-set float voltage 14.1 V!Charging current of the battery will drop slightly to maintain this float voltage! When a yellow LED light is on - DC load is turned on and is drawing power from the battery. 4)Battery Temperature sensorFeedback to the microchip to properly maintain power charging.When the battery is warm,the float voltage will drop and current increase!
