A balcony or roof inverter that accumulates photovoltaic energy and stores it for the winter, when solar production is limited and energy consumption is higher. The storage system can be connected plug and play to balcony photovoltaics or photovoltaic shelters
A bidirectional inverter
Is called EV3600 and it is a bidirectional inverter, i.e. a device that can manage energy flows in both directions: both from direct current to alternating current, converting the energy stored in the battery and making it usable by home devices, and from alternating to direct current, allowing to charge a battery using the energy taken from other alternating current sources (and we will soon find out which ones…).
This inverter allows you to recharge in periods at a reduced rate. The company that developed it is German, it’s called Sunlitand states that the inverter supports feature extensions vehicle-to-home (V2H) e vehicle-to-grid (V2G), i.e. which can exploit the battery of electric vehicles not only to recharge them, but also as an energy resource.
Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G)
The manufacturer wants to make the technology compatible with electric vehicles. The technology V2H allows an electric vehicle to function as a storage device and directly power a home using the energy present in the vehicle’s battery. The technology V2Gon the other hand, gives the electric car the ability to return energy to the network (grid) through a bidirectional charging station.
Inverter characteristics
The inverter is small in size but offers good performance: measure 524mm x 338mm x 292mmweighs 18.8kgoperates at temperatures between -20°C and 45°Cand provides power up to 3.68 kW.
Unfortunately, the inverter only integrates with the storage systems of the same manufacturer. In fact, the company claims that the inverter is simple to install and is compatible with plug-in solar devices “BK215” and “B215” of the same company.
