How to distinguish the capacity of off-grid solar generator systems

Off-grid solar generator systems are made of solar cell panels, battery , controller and inverter etc. But two most important parts are solar cell panels and inverter. They are interworked together to decide all systems’ function directly what kinds of electric appliance can be loaded. So, when descript the capacity of off-grid solar generator systems, that is according to the solar panels and inverter’s rated output capacity. While you are choosing and purchasing off grid system, must composite these two factors.

The capacity of solar cells is the total wattage of solar panels , it decide that solar generator systems can generate how much electric .For example , 300W solar cell panels, it can be one pieces of 300W panel, also two pieces of 150W panels, that representative under the standard lighting conditions one hour can generate 300WH electronic ( equip to 0.3 degree), which also means 300W solar power systems generate electronic per hour.

The rated of inverter output capacity is the Maximum power which can be output, on behalf of the power to drive a certain electrical. For example, a inverter which rated output power is 1000W, drive the electric appliance power must be less than 1000W. in generally, the electric appliance power can not more than 80% rated power of inverter. If the driven electrical appliances are inductive appliances which instantaneous power are more than  rated power several times , such as electromotor, refrigerator, air-conditioner and washing machine etc, the inverter’rated power must be more than electronic appliance’s about 5-8 times. Therefore, a solar generator kit with 1000W inverter, the driven electronic appliance power must be less 1000W.That is why the home solar power generator system need to pay attention to the type of appliance.

For the set of off-grid solar generator systems capacity, we usually means solar cells panels capacity, sometimes also means the rated output capacity of inverter. A set is equipped with 200W solar panels and 500W inverter power generators, which often called 200W solar power system, or 500W off grid solar system. So, when we purchase , had better to think about these two factors.
