MEGA 6/8/10/12 kW single-phase hybrid inverter — inverter fault
Beve 06 error code
Inverter output voltage is above the acceptable window; the manual's troubleshooting table puts this above 260 Vac.
Likely causes
- Output voltage setting too high for the installation
- Large load switched off suddenly, causing a voltage overshoot
- Output voltage regulation fault
Checks to run, in order
- 1Measure the output with a true-RMS meter at no load and with load
- 2Check the output voltage setting against 220/230/240 Vac
- 3Reduce the connected load and observe whether the voltage settles (manual)
Fixes
- Reduce the connected load
- Set the output voltage to the correct nominal value
- If the voltage stays high with no load, return the unit to the repair centre
When to escalate
If output voltage remains above the window at no load after the setting is corrected, the distributor should inspect the output stage.
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.
Questions installers ask
What does Beve 06 mean?
Inverter output voltage is above the acceptable window; the manual's troubleshooting table puts this above 260 Vac.
How do I fix Beve 06?
Reduce the connected load Set the output voltage to the correct nominal value If the voltage stays high with no load, return the unit to the repair centre
When should I escalate Beve 06?
If output voltage remains above the window at no load after the setting is corrected, the distributor should inspect the output stage.
Can I reset Beve 06 myself?
Only after isolating the AC and DC sides and running the checks above. If Beve 06 returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show Beve 06?
Beve 06 is documented for MEGA 6/8/10/12 kW single-phase hybrid inverter — inverter fault. Confirm the code on your own unit's display or manual before ordering parts.
