The solar power battery bank stores the sunlight from the solar panel and stores it . I want to use solar power with my pump that requires AC .So I need to look for a battery bank that has an inverter to do this conversion. In this project, the role of the solar power battery bank is to provide the correct type of energy for the pump to function.
There are three kinds of batteries to choose from:
- Lead Acid
- Lithium-Ion
- Nickel Cadmium
The one I chose was Lithium-Ion (LioN). Within this, there are another 6 main types of lithium batteries. And the one that works best in this situation, is called the Lithium Iron Phosphate battery. This is a popular option for most applications because there are many benefits. The LFP batteries have a long lifespan of 2000 cycles or more. While most LFP batteries have an 80% depth of discharge, this one is rated with a 100% depth of discharge (DoD). And even after this, the battery is not harmed. This battery has excellent thermal stability. The materials are also low resistance, making the battery one of the safest even when fully charged.
The maximum possible rate that the battery bank could charge is 100 watts/hour.
Here is my Solar power battery bank charging. As you can see because of using the correct angle for my zip code the battery bank is charging at almost 90W/hr out of solar panel maximum rated power of 100W/hr.
