Safety When Setting the Battery Management Parameters


This section contains safety information that must be observed at all times when working on or with batteries.

To prevent personal injury or property damage and to ensure long-term operation of batteries and battery inverter, read this section carefully and observe all safety information at all times.

NOTICE

Damage to the battery due to incorrect settings

The set battery parameters influence the charging behavior of the inverter. The battery can be damaged by incorrect settings of the battery type, nominal voltage and capacity parameters.

  1. Set the correct battery type as well as the correct values for nominal voltage and battery capacity when configuring.
  2. Ensure that the values recommended by the manufacturer are set for the battery (refer to the technical data of the battery in the manufacturer documentation).

Normal behavior for new systems with lead-acid batteries

With lead-acid batteries, the Sunny Island requires several charge/discharge cycles to calculate the state of charge correctly. After commissioning, a SOC of 50% is displayed. This figure is adjusted after a few complete charging cycles.
After commissioning a system with lead-acid batteries, a complete charging cycle is started.
