How to chose batteries for kit solar off grid system?

     Generally speaking, there are two kinds of storage batteries in kit solar off grid system, one is lead-acid batteries, the other is AGM gel batteries.In fact, both of them belong to lead-acid batteries. The advantages of the gel battery is high temperature resistance, high capacity and low temperature characteristics. The disadvantage is that the price is higher. The lead-acid batteries has low price. The disadvantage is that the temperature resistance is not very good.

    So how to chose batteries for kit solar off grid system?Generall in kit solar off grid system, large capacity storage battery, small current charge and small current discharge are selected, so that the service life is long and the kit solar off grid system performance is stable.If the kit solar off grid system installation area has low temperature below - 10 degrees, I suggests that use the AGM gel batteries.

   Home solar energy kit is based on the principle of photovoltaic effect, using solar cells to directly convert solar energy into electrical energy.It is mainly composed of solar panels (modules), controllers and inverters. Solar cells can be protected in series to form a large area of solar cell components, and then combined with power controller and other components to form a home solar energy kit system.

   Generally speaking, the average family has a refrigerator, a TV set, plus an air conditioner of 1.5 pieces, two or three lights and so on, which takes about 2,000 watts home solar energy kit. The monthly electricity consumption is about 300KWH. If the roof area is allowed, a 3,000 watt home solar energy kit system is needed.

   Battery selection of domestic solar system generally uses large capacity storage battery, small current charge and current discharge, so that the service life is long and the domestic solar system performance is stable. If the installation area has low temperature below - 10 degrees, it is recommended to consider using domestic solar system storage battery.
