Technical FAQs 4

What is a retrofit inverter in a photovoltaic system?

The retrofit inverters only manage the storage systems and are mainly used in existing photovoltaic systems to keep the system configuration unchanged. In this case, the retrofit inverter of the storage system and the photovoltaic inverter are two distinct machines where the power of the storage is added to the power of the photovoltaic.

What is solar retrofit?

Solar retrofit is the process of upgrading existing solar energy systems to improve their efficiency, functionality, or capacity. This can involve modifications such as adding new solar panels, power optimisers or inverters to meet increased energy demands or enhance system performance.
