Storage systems: connection diagrams

Storage systems can be applied both in already existing PV installations and in new ones.

Different connection diagrams are available

 

1] AC side – all in one storage system: is the connection that preserves the configuration of the existing photovoltaic plant. The distinctive factor for this storage system is that both inverter and battery are present in a unique subject, and there is only one producer who develop the product and provide guarantee for the storage installation. The inverter for the storage and the inverter for the photovoltaics are two different machines and both contribute to the maximum usable power
This type of connection is usually the most used and is the easiest to realize and, therefore, with the least impact on labor cost.

 

2] AC side storage system: is the connection that preserves the configuration of the existing photovoltaic plant. The storage system battery and the inverter are not a single product, and sometimes they are also from different producers. The inverter for the storage and the inverter for the photovoltaics are always two distinct machines.

 

 

3] DC side – all in one storage system: the storage system is fully integrated in the photovoltaic installation and there is only one producer who developed the product and provide the guarantee. The inverter that manage the storage and the photovoltaics energy production is a unique machine; and this is the reason why the efficiency of DC side – all in one storage system is higher than “AC side” systems.

 

 

4] DC side storage system: the storage system is fully integrated in the photovoltaic installation, the battery and the inverter are not a single product and sometimes they have different brands. The inverter that manages the storage and the photovoltaic energy production is a unique machine, with an advantage for efficiency.

 

 

VP Solar has published the Storage Guide that offers a wide view of the different technologies and products, which find detailed commercial proposals and price lists dedicated to resellers and installers in the website private area.
