Didisolar Mppt solar charge Regulator is a Maximum Power Point Tracker (MPPT) charge controller designed to harvest the maximum available energy from the PV array and deliver it to the batteries. The didisolar MPPT algorithm finds the maximum power point of the array ，and operates at this point while regulating the output current and battery voltage to fully charge the battery.
The difference between PWM and MPPT controller
Simple PWM, or pulse width modulation solar charge controllers have a direct connection from the solar array to the battery, and use a basic rapid switch to modulate or control the battery charging. The switch (transistor) is open until the battery reaches the absorption charge voltage. Then the switch starts to open and close rapidly (hundreds of time per second) to reduce the current and maintain a constant battery voltage. This works ok, but the problem is the solar panel voltage is pulled down to match the battery voltage. This in turn pulls the panel voltage away from its optimum operating voltage (Vmp) and reduces efficiency.
MPPT or ‘maximum power point tracking’ controllers are far more advanced than PWM controllers and enable the solar panel to operate at its optimum voltage for maximum power output. Using this clever technology, MPPT solar charge controllers can be up to 30% more efficient, depending on the battery voltage and type of solar panel connected. The reasons for the increased efficiency and how to correctly size an MPPT charge controller is explained in detail below. As a general rule MPPT charge controllers should be used on all higher power system with 2 or more panels, or whenever the panel voltage is much higher than the battery voltage
