The answer is of course. Solar energy is the most abundant energy available to human being. It can be used on-site without transportation problems. With more and more serious environmental pollution today, the development and utilization of solar energy is becoming more and more important. The solar panel can convert the sun’s light energy into electrical energy, then the output direct current is stored in the battery. If you use a solar panel, it can definitely charge the battery. Because solar panels are greatly affected by light. Shadows and changes in the angle of the sun’s rays make the output voltage of the solar panel unstable. Generally speaking, we need to connect a stable voltage and voltage charge controller between the solar panel and the battery, also called solar regulators. It can not only stabilize the current, but also automatic protection functions such as overcharge, over discharge, overload, anti-reverse connection and short circuit. GEL battery GEL battery is the moderate price deep cycle battery. It is more popular for use in household solar system batteries. When the depth of discharge of GEL battery reaches 80%, the cycle life of GEL battery reaches 800 times. And it is also the maintenance free battery. OPzV battery OPzV battery is tubular plate GEL battery. The design of the special structure makes the self-discharge rate of the battery extremely low, which is especially suitable for the renewable energy storage system where the temperature difference and the grid is unstable or in a long-term power deficit. When the depth of discharge of OPzV battery reaches 80%, the cycle life of OPzV battery reaches 2100 times. And you don’t need to maintain the battery. OPzS battery OPzS battery is tubular plate flooded battery. It need to be maintained regularly. But OPzS has the longest cycle life. When the depth of discharge of OPzS battery reaches 80%, the cycle life of OPzS battery reaches 2300 times. Customer can decide the deep cycle according to their own actual situation. No matter which deep cycle battery you choose, VELA can provide you with high-quality, reliable batteries.
