MEGA 6/8/10/12 kW single-phase hybrid inverter — inverter fault

Beve 17 error code

LLC resonant converter short-circuit fault.

Likely causes

  • Power-stage component failure in the LLC converter
  • Output short or over-current event damaging the power stage
  • Internal gate driver fault

Checks to run, in order

  1. 1Isolate the output and restart once
  2. 2Check the output for a short before restarting
  3. 3Note whether the code appears immediately at start-up or only under load

Fixes

  • Restart only after any output short is cleared
  • Return the unit to the repair centre; an LLC fault is an internal power-stage failure

When to escalate

Code 17 should not be cleared by repeated restarts; the distributor must test the LLC power 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.
