Solar battery is the application of "battery" in solar photovoltaic power system. The currently widely used solar storage battery is GEL solar battery. It has excellent cycle performance and overdischarge recovery ability. Its unique pole group structure and process design enable the battery to release higher energy, adopt gas recombination technology, and do not need to add water for maintenance during use. High-purity raw materials are meticulously crafted to ensure that the self-discharge rate is extremely small; the design life is as long as 12 years.
1. The working principle of GEL solar battery
Sunlight shines on the solar modules during the day, so that the solar modules generate a certain range of DC voltage, convert the light energy into electric energy, and then transmit it to the intelligent controller. After the intelligent controller’s overcharge protection, the electric energy from the solar modules is transferred. It is transported to storage battery for storage; storage requires storage battery. The so-called storage battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.
2. The following mainly introduces the characteristics of GEL solar batteries:
①Use in colloidal state: 100% sealing efficiency.
②Long-term discharge characteristics, small self-discharge electrode: It can be stored for up to two years (20℃) with electricity for a long time, and the storage period is 4 times that of the adsorption battery. It can be put into use immediately without supplementary power.
③Low water loss rate: The water loss rate is only 1/2 of that of the adsorption battery, which effectively alleviates the early drying of the electrolyte.
④Long service life: The gel battery has a design life of more than 12 years, which saves money.
⑤Excellent performance in deep discharge cycle: It is especially suitable for cyclic use. The 100% deep discharge cycle and life span exceed 500 times, which is much higher than that of the adsorption battery, which effectively improves the reliability of the system.
⑥Excellent recovery performance after over-discharge: over-discharge to "0"V, it can still recover well, after 21 days of 1CA discharge, the battery's recovery capacity reaches 100%.
⑦Wide application environment: It can be used in the temperature range of -40℃~60℃, and its performance greatly exceeds the adsorption battery. To
⑧The particle size of fumed silica is small and the specific surface area is large.
With the widespread use of solar photovoltaic power generation systems, more and more people pay more and more attention to batteries as a supporting battery. When purchasing solar batteries, you can refer to the characteristics of GEL colloidal solar batteries to understand the electrical performance of the batteries, including product design parameters for appropriate selection.
