MEGA 6/8/10/12 kW single-phase hybrid inverter — inverter fault
Beve 07 error code
Overload: the inverter has been running above its rating (102% in the manual's note) until the overload time expired.
Likely causes
- Connected load greater than the inverter's rated output
- Motor, pump or compressor start-up surge
- Too many appliances on the backup output
- Load left on the smaller sub-load output beyond its rating
Checks to run, in order
- 1Add up the running wattage of everything on the backup output
- 2Check the start-up surge of motors and compressors
- 3Confirm which loads are on the main and sub-load outputs
- 4Check the history error page for repeated overload events
Fixes
- Reduce the connected load by switching off some equipment (manual)
- Stagger the starting of heavy appliances
- Move part of the load to another output or to the grid
When to escalate
The manual warns that after three overload alarms the machine may not start again; if it stays locked, the distributor must reset or service it.
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.

When should I escalate Beve 07?
The manual warns that after three overload alarms the machine may not start again; if it stays locked, the distributor must reset or service it.
Can I reset Beve 07 myself?
Only after isolating the AC and DC sides and running the checks above. If Beve 07 returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show Beve 07?
Beve 07 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.
