Sealed Solar Battery stores energy collected from solar panels. The higher the battery capacity, the more solar energy can be stored. In order to use the battery as part of a solar device, you need a solar panel, a charge controller, and an inverter.

　　First, your solar panels need to be connected to a charge controller, which will help monitor how much energy is stored in the battery to prevent overcharging. If the battery is seriously low, the charge controller will also shut down the system. Before powering the device, your battery needs to be connected to the inverter to convert the DC energy collected from the solar panels into AC energy.

　　When using the battery of a solar panel as part of a home solar system, you can store the excess electricity generated by the solar panel without having to send the energy back to the grid. If your battery is fully charged and the panel is still producing energy, the electricity will be sent to the grid.

　　What should be considered when choosing deep-cycle batteries for solar panels?

　　When purchasing deep-cycle batteries for solar installations, there are a few different factors to consider: price, capacity, voltage, and cycle life.

　　Price: The price of the battery ranges from about $100 for the cheapest lead-acid battery to more than $1,500 for lithium-ion batteries. Be sure to consider the final service life, not just the initial cost, because you must replace the lead-acid battery before you need to replace the lithium-ion battery. You also need to do more maintenance on batteries full of lead-acid. We all know that time means money.

　　Capacity: Sealed Solar Battery capacity is important because it can measure the amount of electricity you can store. If you need to power certain devices for a long time, you need more batteries to bear the larger load. Capacity is measured in total ampere-hours.

　　Voltage: Be sure to check the voltage of the battery pack to make sure it is compatible with your panel and the rest of the system, especially with solar panels. The panel usually has 12V and 24V options. Most RVs and boats usually use 12V battery packs, so people usually stick to 12V panels. The advantage of using a higher voltage battery pack is that you can save money in the long run because you need fewer charge controllers and you can use a thinner cable to get the same amount of power. If your energy needs exceed 3KW, please choose a 48-volt system. Large off-grid houses usually use 48V.

　　Cycle life: This specifies the number of discharge and charge cycles that the battery can provide before the capacity drops below the rated capacity. There is a big difference between different technologies and is measured by the number of cycles.
