  1. High Bus Voltage Error on MUST 5KVA Inverter

    JLER3 replied to Sheyn's topic in Inverters
    Coulomb. No PV panels installed yet. Just want to use the system as a backup during load shedding. Switchover from Utility to Inverter very smooth. Code 08 - Bus voltage to high. What I noticed is that during while running in backup mode the frequency is only 41Hz instead of 50 Hz.

  3. High Bus Voltage Error on MUST 5KVA Inverter

    JLER3 replied to Sheyn's topic in Inverters
    Just installed a new 48V 5KVA inverter with 4x 100Ah gel batteries. Backup DB has 25A input and output breakers with 3-way bypass switch and 125A DC circuit breaker. When testing the system I switch off main switch on main DB to activate the backup system. The changeover from ESKOM to inverter is faultless BUT the lights does a short flick every 10 - 20 seconds. A typical relay click is heard from the inverter. Red light on screen shows code 08 - Bus voltage to high. How can I fix this problem. Thanks Johan.
