What it means

Battery Over Voltage protectionListed under 7.1 Battery System Features 'Battery Protection': protects against over-voltage at the battery side (max charge voltage 57.6 V per spec).

Cause: Battery voltage rose above the over-voltage protection value — the charger or inverter is applying more than the pack's 57.6 V maximum charge voltage, or failed to taper off at the end of charge.

How to fix it

  1. Power down the inverter, wait 5 minutes for capacitors to discharge, then restart.
  2. If the fault recurs immediately or repeatedly, record the exact code and contact your installer or the manufacturer's service line.
