How to configure a maintenance-free lead-acid battery for solar panels

- Jan 11, 2019-

The reduced lead acid relies on the battery to reduce the liquid during use. This is because the front of the fine frame will dye the front plate on the negative plate, which reduces the battery and the electric potential in the battery after full charge. The decomposition of the water is decomposed, and the gas on the positive and negative plates is released from the positive and negative plates to reduce the electrolyte.


Solar panels are devices that directly or indirectly convert solar radiation into electrical energy through photoelectric or photochemical effects by absorbing sunlight. The main material of most solar panels is “silicon”, but the cost of production is relatively high. So large that it has some limitations in its widespread use. Compared with ordinary batteries and rechargeable batteries, solar panels are greener products that are more energy-efficient and environmentally friendly.


Therefore, it is necessary to replenish the electrolyte regularly, which increases the maintenance workload. The maintenance-free lead-acid battery adopts the lead-calcium alloy grid. The water decomposition generated during charging is the least, the gasification speed of the wave body is reduced. The evaporation of water is low, and the positive electrode plate is charged. The oxygen generated on the surface is reduced to water on the negative plate by the recombination reaction, and it is not necessary to add water for maintenance during the life of the specified float. In addition, some other measures are taken, such as the sealed structure of the outer casing, the labyrinth chamber in the structure, the specially designed gas plastic rubber porous breathable valve, and the rich liquid design scheme, which is more than the general lead-acid battery. 20% acid solution, using porous low-resistance PE separator, the acid group is filled around the pole group and the tank body, has a large heat capacity and good heat dissipation, does not generate heat accumulation and thermal runaway, is subject to temperature The effect is smaller than that of a general battery, thus eliminating the dryness failure of the lead-acid battery. The maintenance-free sealed lead-acid battery has less sulfuric acid gas released, so it has no need to add any liquid compared with the traditional battery, and it has less corrosion on the wiring of the terminal pile head, good internal low temperature and low temperature start performance, and resistance to no electricity. Strong, high starting current, long battery life, no leakage of acid transportation and convenient maintenance, etc., has been widely used in small and medium-sized photovoltaic systems.
