Inverter Settings - Weco HeSU 4K4-R19/4 Product Manual

WeCo - HeSU 4K4 Low Voltage UNIVERSAL STACKABLE MODEL
NON COMMUNICATION INVERTER SETTINGS
WeCO HeSU has a special Chemical Lithium Iron Phosphate.
After the charging period the total voltage may drop from 54/55 V to 53/52V, this is a normal behavior.
Do not insist with continuous recharge once the High Voltage or Cut Off (SOC 100%) has been reached.
In case of single cell overvoltage, the relay will open the circuit and the inverter will shut down
In this case press the RUN button and shut down the battery,
The BMS allow a self restart 4 times every 4 minutes.
In case the current or voltage limit has been passed for 4 time consecutively the operator must wait 30
minutes before press RUN once again.
A reduction of the charging current and new set up of the voltage is mandatory.
