MEGA 6/8/10/12 kW single-phase hybrid inverter — inverter fault
Beve 80 error code
Parallel communication failure between units.
Likely causes
- Parallel communication cable disconnected or damaged
- Cable plugged into the wrong port
- One unit powered off
- Communication board fault
Checks to run, in order
- 1Inspect the parallel communication cable between each pair of units
- 2Confirm every unit is powered on
- 3Check the cable is in the correct parallel port
- 4Reseat both ends of each cable
Fixes
- Replace the faulty communication cable
- Restart the parallel system
- If the code remains with new cables, return the affected unit to the repair centre
When to escalate
If communication still fails with known-good cables and all units powered, the distributor should test the parallel communication board.
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 80?
If communication still fails with known-good cables and all units powered, the distributor should test the parallel communication board.
Can I reset Beve 80 myself?
Only after isolating the AC and DC sides and running the checks above. If Beve 80 returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show Beve 80?
Beve 80 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.
