Why we recommend buy MPPT Solar Controller?
MPPT circuit solar controllers are considerably more elaborate than PWM. The voltage of the solar panel changes with time of day and temperature. The optimum voltage for battery charging changes as the state of charge of the battery. The MPPT charge controller matches these voltages and can result in 30% more efficient transfer of power. This means good MPPT solar charge controllers can reduce the number of solar panels needed by up to 30%- a tremendous benefit. Even if the excess panels are purchased, benefits are realized in a Grid Tie system because more electricity can be sold back to the grid. While only a small part of system price, a MPPT solar panel charge controller can leverage the rest of the system to better performance.

Specifications: Solar panel:Polycrystalline 11V 30W Battery:Lithium battery,7.4V 13AH Light source:2x2W LED+2x3W LED Functionality: THE PANEL OF THE SYSTEM: Chagre:The red indicator light will turn on when connect to solar panel and there is a input power from solar panel. Load:The indicator light will turn on once any of the five outlets has been connect to load and there is a output of power. BATERY VOLTAGE:(1)Yellow area :low level of power stored in battery,the protection of over discharge function initiates ; (2)Green area :medium level of power,this area shows the battery works in normal condition. (3)Red area :high level of power,the protection of over charge function initiates. POWER :the switch for the whole system (1)When turn on this switch,all five outlets are ready to export power.The battery voltage needle points to Green area and shows how much power is stored in the battery. (2)When turn off this switch,all five outlets stop to export power.The battery voltage needle points to zero. IN CHARGE :connect to solar panel to charge the battery.The solar panel will charge the battery no matter the switch is being Turned ON or OFF.When the solar panel is connected to IN CHARGE and the switch is Turned ON,the CHARGE indicator will be lit up and the BATTERY VOLTAGE shows how much power the battery stores.The system can be charged and export power at the same time. NOTE:Except solar panel,this system can be charged by AC or DC power.Recommend to use transformer: AC :100V-240Vwith a power output DC :9V 2A.

Key Component of a Solar System Over 15 Watts A charge controller is a very important feature of a solar system and must be used on all systems over 15 Watts. A charge controller protects your batteries from overcharge and discharge. Charge controllers are the maintenance free protection of your solar panel and batteries. A charge controller monitors the batteryâ€™s state-of-charge to insure that when the battery needs change-current, it gets it, and also insures the battery isnâ€™t overcharged. Connecting a solar panel to a battery without a regulator seriously risks damaging the battery and potentially causing a safety concern. Charge controllers are rated based on the amount of amperage they can process from a solar array.
