Installing solar panels on the roof of a private house or country cottage can almost completely solve the problem of electrification. The building will be completely non-volatile, but there is one condition. Sunlight is not always available, and stored energy must be stored. What rechargeable batteries more are optimal for accumulation, retention and return of electric current, this article will tell.
Absorbent Glass Mat
Conventional lead-acid power supplies used in automobiles are absolutely not suitable for indoor use. During normal operation, they release a gas hazardous to humans into the atmosphere. Flammable if collected in sufficient concentration. And you won't be able to use the full capacity of batteries with liquid electrolyte.
It will be much more practical to choose power supplies made using the absorbed electrolyte technology. They have been specially designed for vehicles with a start /stop motor function and are ideal as primary batteries for solar panels. The main advantages are:
- perfectly withstand deep discharge;
- capable of transferring up to 600 full cycles of discharge and subsequent charge;
- under normal load, the manufacturer guarantees their operation for 10 years;
- absolutely do not need technical inspection;
- a sealed case, in which there is no liquid electrolyte.
Disadvantages of technology
It is only one, AGM batteries do not tolerate significant temperature changes. The optimum is considered to be from -30 to +50 degrees, which is not at all difficult to organize in the conditions of even partially heated houses.
