How does the state of charge affect a battery?

The state of charge influences a battery's ability to provide energy or ancillary services to the grid at any given time. Round-trip eficiency, measured as a percentage, is a ratio of the energy charged to the battery to the energy discharged from the battery.

How does a battery charging system work?

Customers can set an upper limit for charging and discharging power. During the charging period, the system prioritizes charging the battery first from PV, then from the power grid until the cut-off SOC is reached. After reaching the cut-off SOC, the battery will not discharge, and the photovoltaic output will also be normal.

How does a battery pack work?
