Examples of Lead Acid Battery Charge Voltage
Bulk 14.4V
Absorb 13.8V
Float 13.3V
Equalization 15V
| x 2 for 24 V x 4 for 48V |
By understanding the different voltages you can effectively manage your storage cells and the energy flow from the PV array to the load. This understanding should increase the lifespan of your batteries.
Flow and lithium batteries do not use the same principles as lead acids. These batteries generally come in 48V format and have standard charging voltages. The difference between these technologies is indicated in the graphs below.
