Storage Solution RS Hybrid Three-Phase with Riello Solartech batteries which combines intelligent energy management and energy storage with constant monitoring of photovoltaic production in a single product.

The RS Hybrid Three-Phase hybrid storage system 8.0 (ESS – Energy Storage System) is designed to continuously supply energy to the loads connected to it using, depending on the different power supply situations, photovoltaic energy, mains power and/or energy accumulated in dedicated battery modules. In the event of a lack of sunlight, high energy demand or blackouts, the energy stored in the system can be used to meet energy needs at no additional cost. Furthermore, the energy storage system helps to pursue the goal of energy self-consumption and energy independence.

The three-phase hybrid solution is designed mainly for commercial and industrial projects but can also be used in residential applications.

RS Hybrid 8.0 three-phase, has a design that combines aesthetics with safety, installation functionality and maintenance. These inverters are high-performance and reach a maximum European efficiency close to 98%.

If used in combination with Riello Solartech batteries of the appropriate size, reduces minimum withdrawal from the networkensuring economic savings in a short time and the improvement of the degree of autonomy from one’s network manager. Therefore, in environmental sustainability, make the most of system means reducing energy withdrawals from traditional fuels to a minimum, consequently reducing CO2 emissions.

Batteries require an HV-RS BOX battery management unit to coordinate the energy in the battery to flow to and from the inverter.
