There are several storage technologies: Gel or AGM batteries, lithium batteries, OPzS and OPsV. It's not easy to choose the right technology for your needs. Each technology has its own characteristics (size, power, cost, number of cycles and service life, etc.). With this table, you can quickly compare the price per useful kWh over the lifetime of the batteries.
C10 = 10-hour charge/discharge test.
C24 = examination of a charge or discharge in 24 hours.
