Charger Power Insufficient for Charging Time

Fronius · Perfect Charging

What does 213 mean?

The charger's power output is not sufficient to charge the connected battery within the desired or configured charging time. This is primarily a planning or sizing issue rather than an immediate hardware fault, leading to prolonged charge cycles.

Common Causes

  • The desired charging time is too short for the battery's capacity and the charger's rated power output.
  • The charger is operating at a reduced output power, either intentionally or due to internal conditions.
  • The actual battery capacity is larger than estimated or configured, requiring more energy to fully charge.
