and battery neither charges nor discharges. For abnormal battery charging and discharging, the following troubleshooting work is required: 1. Check whether the air switch between the battery and the energy storage inverter is closed (it is recommended to use a multimeter to test the battery voltage on the inverter side.
Check, if the battery does not discharge only at night, analyse the load power (as in Fig.1). When the load takes more than 150W from the power grid, the battery is allowed to discharge, otherwise the inverter will not discharge. This is to prevent that the inverter losses become comparable to the house load. 8.
The module will monitor the voltage of the battery as its being consumed by the circuit (load). When it goes below the critical value (3.7V) the module will automatically disconnect your battery form the load and protect your battery from over discharge.
If your battery control module is not functioning properly, you may need to send it in for repair. Some common symptoms of a BCM that are not properly programmed include reduced run time, reduced capacity, and even full discharge of the battery pack.
As we know a lithium battery should not be overcharged or over discharged, hence this module will monitor the voltage level of the battery during charging and discharging. If the values go beyond critical value the module will automatically disconnect the circuit and protect your battery.
Problems related to battery charging and discharging of SHxxRS and SHxxRT and the guidance of troubleshooting Battery charging and discharging problems can occur in residential energy storage inverters. There are mainly three cases: battery does not discharge, battery does not charge, and battery neither charges nor discharges.
