An off-grid solar system permits electricity to be harnessed by solar panels and stored inside a battery without direct connection to the utility grid, providing an independent power supply to your home or business.
Off Grid Solar Power System Working Principle
1. Solar Panels (PV array). Solar panels are set either on your rooftop or in an open yard or property space. The Sunlight is
soaked up by the solar panels and transferred to the charge controllers.
2. MPPT/PWM Solar Charge Controllers. The charge controller is the “delivery man” between the solar panels, the inverters, and the
battery bank. Charge controllers also act as a regulator, ensuring that the amount of power received through the solar panels does
not overload the battery, instead keep the battery fully charged and top it off when needed. The charge controllers either deliver
the energy directly as DC power to your lights or to the inverters to be converted into AC power for household appliances and all
excess energy goes to battery bank.
3. Solar Battery Bank. With the charge controllers feeding energy to the batteries, the battery bank acts as the heart of the
off-grid solar system, as it stores up excess energy for cloudy days and nights, when needed it pumps electricity to inverter and
power your house.
4. Off grid solar Inverters. Lastly, inverters convert the DC (direct current) power into AC power which is passed on to be
digested by your electronics or appliances as DC power and allows you to switch on the TV or fry up an egg.
