How To Estimate The Battery Soc; Battery Management System - Renogy Pro Benutzerhandbuch

How to Estimate the Battery SOC?

The SOC values listed below are estimated based on the resting voltage (open-circuit voltage at rest)
when the battery is at rest for 30 minutes, not in charging or discharging state.
SOC
100%
99%
90%
70%
40%
The table above is for reference only because slight variations in battery voltage may occur
among different batteries.

Battery Management System

This smart battery management system has more than 60 fault alarms and protections to fully
protect your battery safety. Below we list some common faults and protections for reference.
