+263 78 922 2847Learn to Decode MUST Inverter Error Codes, Troubleshoot Battery and Power Issues, and Restore Your Solar System Efficiently
Most inverter errors are related to the battery, making proper battery maintenance and monitoring crucial for reliable solar system performance. On MUST inverters, some of the most common battery-related issues include Error 04: Battery Voltage Too Low and Warning 64: Low Battery. Error 04 occurs when the battery voltage drops below the minimum safe level, which can happen due to depleted batteries, a faulty cell, or loose and corroded terminals.
Common Battery-Related Errors
Meaning: The battery voltage has dropped below the minimum safe level. The inverter shuts down to protect the battery from deep discharge damage.
Cause: Depleted batteries, a faulty cell, loose or corroded terminals, or an overloaded system.
Meaning: The DC voltage from the battery is higher than the inverter's limit.
Cause: Incorrect charging settings (e.g., for the wrong battery type), or a malfunctioning charging source like a generator or solar charge controller.
Meaning: The inverter does not detect a proper connection to the battery bank.
Cause: A loose terminal, a blown DC fuse between the battery and inverter, or a completely disconnected cable.
System & Component Faults
Error 01: Fan is locked. The cooling fan is obstructed or has failed.
Error 02: Inverter transformer over temperature. The transformer has exceeded its safe operating temperature.
Error 27: Inverter radiator over temperature. The heatsink is too hot. All these errors are typically caused by prolonged heavy loads or poor ventilation.
Error 05: Output short circuited. A critical shutdown caused by faulty wiring or a malfunctioning appliance.
Error 06 / 58: Output voltage is high / low. The AC output voltage is outside the acceptable range, likely due to an internal failure.
Error 07: Overload time out. The inverter has supplied more power than its rated capacity for too long. Reduce the number of connected appliances.
Error 08: Inverter bus voltage is too high. The internal DC bus voltage has exceeded its safe limit.
Common Warning Codes
Warning 63: Battery is over-charged. The battery voltage has exceeded the safe limit. The inverter will stop charging to protect the batteries.
Warning 64: Low battery. A pre-emptive alert that your battery is low on charge. Reduce your load to prolong runtime.
Warning 67: Overload. The power being drawn exceeds the inverter's capacity. The inverter will beep before shutting down with Error 07.
Warning 70: Output power derating. The inverter is reducing its power output to prevent overheating, typically due to heavy loads or high ambient temperatures.
Frequently Asked Questions
Press and hold the "ENTER" button for 3 seconds. Use the "UP" and "DOWN" arrows to navigate through the program numbers, "ENTER" to select a program, the arrows to change its value, and "ENTER" again to confirm. Press "ESC" to exit.
For a soft reset, turn off all power inputs (Grid and PV), then turn off the inverter. Wait one minute for the screen to go blank. Turn the inverter back on, followed by the PV and Grid inputs. For a full factory reset, you can find the reset option in the settings menu (consult your user manual).
Still Having Trouble?
If you're facing a persistent error code or are unsure about a fault, it's best to seek professional help. Contact the Sona Solar Zimbabwe technical team for expert support and service.
