If you’re thinking about adding a solar battery storage system to your home or business, you may be wondering how to choose the best one. It’s not as simple as buying the biggest battery with the highest wattage—you should also consider some other factors that will ensure you get the best performance out of your battery.
A good way to start is by looking at these five points of comparison:
1、System type – It’s important to keep the kind of system you have in mind when choosing the right solar battery. Off-grid systems have higher energy demands than hybrid systems that only need a battery for backup energy.
2、Capacity – The storage capacity of batteries in kilowatt-hours (kWh) measures the total amount of energy that the battery can store.
3、Round-trip efficiency – This measurement refers to the amount of energy it takes to store a battery versus the amount of energy the battery provides. All batteries will lose some charge while storing energy, but less energy loss means greater round-trip efficiency.
4、Depth of discharge – Solar batteries cannot completely deplete without damaging them
5、Battery life – Battery efficiency will decline over time, so look for a battery with a longer life that will maintain high efficiency for a more extended period of time.
