how to select properly, protection of PV systems in PVSol


Recommended Posts

Hi Graniti,

this kind of information can't be provided by us, I am afraid. It depends on the local requirements (i.e. what do national and local standards say).

Usually you will have at least an over voltage protection device and a circuit breaker on the DC side between PV modules and inverter, as well as a circuit breaker on the AC side between inverter and counter. For larger systems you will also have a fuse for each string on the DC side. But it really depends on the system you plan and local requirements.

Try to find an electrical engineering technician with experience of your local market and the common rules of PV system security.

Kind regards,
