Riello Solartech: Hybrid inverters integrated with an Energy Storage system for residential applications:

• RS Hybrid 3.6 and 6.0 single-phase, coupled with Lithium-ion battery modules, allow to expand the functionality of an On Grid photovoltaic system and at the same time to realize a backup with the possibility of dedicating a preferential line to certain loads in case of grid failure.
• With an attractive design and a simple plug & play installation, the system thanks to the energy storage (storage) scalable up to 6 modules of 5.12 kWh in parallel configuration, allows to store the energy produced by the photovoltaic system and not self-consumed, in order to use it in the evening hours or in periods of low solar irradiation. The system is thus independent of the power distribution grid and promotes energy savings.
• The single-phase RS Hybrid inverters, as in the previous generation, are available in 3.6 and 6 kW ratings, are equipped with DC-side disconnect switches and batteries, have category 2 surge arresters for immediate plug-and-play installation (requiring no additional field panels) and recharge the batteries themselves.
• To ensure maximum configuration flexibility, yield optimization and extended energy production time at all times, RS Hybrid inverters feature 2 PV inputs that converge on 2 MPPT trackers. The MMPPT trackers are independent and feature self-learning technology with wide range and input voltage and a low threshold for delivery to the grid.
• Ventilation is natural convection with large and efficient heat sink to ensure maximum heat transfer and total silence
• Finally, the inverters are equipped with a built-in backup module that, in the event of a grid failure, supports the load from the battery until the grid returns (tripping time less than 10ms).
• To optimize backup, a line can be defined that supports the full rated power of the inverter. Inverter management is simple and intuitive: there are 6 LEDs on the front panel that allow you to quickly identify its operating status or signal any alarms
• There are multiple communication options with the inverter: Bluetooth, RS485 (ModBus), Wi-Fi and Ethernet (optional): all can interface with the configuration APP and monitoring software for real-time system status display and control (APP and supervision WEB portal)
• RS Hybrid inverters have an IP65 system protection rating, making it suitable for outdoor installation.

RS HYBRID inverters are available in 3.6 and 6 kW ratings, equipped with DC, AC and battery side disconnect switches and cat. 2 surge arresters for immediate plug & play installation without the need for additional field switchboards.
