Solar photovoltaic system or Solar power system is one of renewable energy system which uses PV modules to convert sunlight into electricity. The electricity generated can be either stored or used directly, fed back into grid line or combined with one or more other electricity generators or more renewable energy source. Solar PV system is very reliable and clean source of electricity that can suit a wide range of applications such as residence, industry, agriculture, livestock, etc.
Solar PV system includes different components that should be selected according to your system type, site location and applications.
Major system components
• PV module – converts sunlight into DC electricity.
• Solar charge controller – regulates the voltage and current coming from the PV panels going to
battery and prevents battery overcharging and prolongs the battery life.
• Inverter – converts DC output of PV panels or wind turbine into a clean AC current for AC
appliances or fed back into grid line.
• Battery – stores energy for supplying to electrical appliances when there is a demand.
• Load – is electrical appliances that connected to solar PV system such as lights, radio, TV, computer, pump,refrigerator, etc.
• Auxiliary energy sources - is diesel generator or other renewable energy sources.

Solar Off grid inverter
1. Toroidal transformer of light weight, small size, high conversion efficiency, low power consumption, good load capacity and load adaptability, etc.
2. AC input automatic voltage regulator (AVR), input voltage range of 145V ~ 275V.
3. Liquid crystal (LCD) display, backlight power saving mode. The main display real-time battery voltage, battery capacity, input and output voltage, output frequency, duty ratio, etc. Automatically switch the display according to different working conditions.
4. Having overload, battery overcharge, over discharge, output short circuit, over-temperature protection features.
5. Full SMD modular structure, stable performance, easy maintenance.
Off grid solar charge controller
Solar panels may make power at very high voltage and current. If all that is fed directly to the battery then it may get overcharged or blast (in extreme cases).
A solar charge controller prevents this from happening. It is is placed in between the solar panels and the battery bank to regulate the charging (current and voltage) of the batteries through solar.
Basically, without a charge controller it is not possible to safely use solar energy for charging batteries.
