MEGA 6/8/10/12 kW single-phase hybrid inverter — inverter fault
Beve 02 error code
Inverter temperature has exceeded its protection point.
Likely causes
- Airflow through the unit is blocked
- Ambient temperature at the installation is too high
- Cooling fan not running
- Dust-clogged heatsink
- Sustained overload heating the power stage
Checks to run, in order
- 1Check whether the airflow of the unit is blocked or the ambient temperature is too high (manual)
- 2Confirm the fan runs while the unit is hot
- 3Compare the connected load with the inverter rating
- 4Check clearances around the mounting position
Fixes
- Clear the airflow path and remove dust from the heatsink
- Improve ventilation or shade the installation
- Reduce connected load and let the unit cool before restarting
When to escalate
If the alarm trips with clear airflow, a running fan and normal ambient temperature, the temperature sensor or power stage needs distributor inspection.
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 02 mean?
Inverter temperature has exceeded its protection point.
How do I fix Beve 02?
Clear the airflow path and remove dust from the heatsink Improve ventilation or shade the installation Reduce connected load and let the unit cool before restarting
When should I escalate Beve 02?
If the alarm trips with clear airflow, a running fan and normal ambient temperature, the temperature sensor or power stage needs distributor inspection.
Can I reset Beve 02 myself?
Only after isolating the AC and DC sides and running the checks above. If Beve 02 returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show Beve 02?
Beve 02 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.
More Beve error codes
- Beve 01Cooling fan is locked and not turning while the inverter is switched on.
- Beve 03Battery voltage is above the inverter's high battery cut-off.
- Beve 05Output short circuit detected on the inverter AC output.
- Beve 06Inverter output voltage is above the acceptable window; the manual's troubleshooting table puts this above 260 Vac.
- Beve 07Overload: the inverter has been running above its rating (102% in the manual's note) until the overload time expired.
- Beve 08Internal DC bus voltage is above its limit.
