MEGA 6/8/10/12 kW single-phase hybrid inverter — inverter fault
Beve 01 error code
Cooling fan is locked and not turning while the inverter is switched on.
Likely causes
- Fan blade obstructed by dust, debris or a foreign object
- Fan connector loose or disconnected from the control board
- Fan motor seized or worn out
- Fan cable damaged
Checks to run, in order
- 1Isolate the unit and inspect the fan intake and blades for obstruction
- 2Power the unit and watch whether the fan starts when it should run
- 3Check the fan connector on the control board
- 4Confirm the heatsink and airflow path are clear
Fixes
- Clear dust and debris from the fan and heatsink
- Reseat the fan connector
- Replace the fan; the manual's remedy for code 01 is to replace the fan
When to escalate
If a new fan still does not run or code 01 returns, the fan drive circuit needs distributor service.
Fix it with the right tools
Check the system around the fault before replacing parts: load, battery bank, PV string and commissioning settings. If you need a second opinion, send the code and your inverter model to our team.
Before you open the inverter
- Isolate both the AC and DC sides, then confirm the display is dead before touching terminals.
- Use insulated tools and one hand where possible. DC arcs do not self-extinguish like AC.
- If you see burnt terminals, swollen cells, leaking electrolyte or a burning smell, stop and escalate instead of resetting the fault.
