Growatt Installation Circuit Breakers

Depending on the type of Growatt inverter used, the correct installation circuit breaker must be chosen. Below you will find an overview of the suitable installation circuit breakers for the hybrid inverter series MIN, MOD and MID series from Growatt.

Suitable Installation Circuit Breakers for Growatt Inverters with Backup Functionality

Are you working with the Growatt WIT4-15K-HU or an inverter from the MOD-HU series? Then it is important to carefully consider the correct installation circuit breaker. The correct choice depends on how the system is configured.

Two scenarios, two tables
To keep it clear, we have created two tables:

1. Without using the backup output
   This table shows the maximum AC current on the regular grid connection (AC grid side).

2. Using the backup output
   Here you see the maximum output on the backup load connection. (this applies to both on and off-grid)

Note: the configuration of your installation ultimately determines which installation circuit breaker is suitable. Always match the protection carefully to the intended use of the inverter.
