Sony Energy Storage Systems

Sony Energy Storage Systems

Sony's Fortelion Olivine Energy Storage Systems are highly scalable due to their modular design. The decisive advantages compared with conventional batteries is 3 to 5 times longer service life, high cycle durability, 95% efficiency and an extremely compact design.

The Energy Storage Systems (ESS) are compatible SMA Sunny Island 6.0H, 8.0H, SMA Sunny Boy and Neap Power Router. A microprocessor supervises all relevant parameters and communicates alarms to the controller. In case of malfunction, it can enforce a system shutdown. This Lithium-Iron-Phosphate Energy Storage System is designed for long cycle life and lifetime.


  • Energy storage for PV system installed homes and buildings to maximize onsite consumption
  • Peak shift for commercial / industrial daily energy operations
  • Community level or micro-grid applications
  • Backup power source for wireless base stations, data centers
  • Peak power supply for e-mobility charging stations

Energy Storage Systems

Energy Storage Systems supplied and installed by Solenttech use modular lithium-ion energy storage technology, solar power generated and stored in battery modules for immediate use or for future energy consumption requirements.

Energy can either be fed into the grid by an inverter (Nedap or SMA) when suitable or can be accumulated in the energy storage system. The energy is available when required: in the evening, at night and on days with less sunshine.

As a producer of solar energy using an Energy Storage System (ESS) the user is more independent and not reliant upon the grid and therefore use energy when they need it.

The systems we supply and install are approved by and compatible with Nedap and SMA grid inverters.

The grid is changing with levels of renewable generation predicted to rapidly increase and loads such as plug in electric cars predicted for the following reasons:

  • Power system integrity, reliability and quality will become critical considerations when considering the connection of new generation and loads.
  • Innovative new power electronic grid support solutions will become available allowing higher levels of renewables grid penetration than previously thought possible.
  • New methods for peak load levelling, providing spinning reserve and system frequency control will become available.


  • Powered by Sony’s iron phosphate cells, “Fortelion”

  • A built-in self-monitoring function detects any abnormality within the module itself

  • Multiple modules can easily be connected either in series or in parallel

System Scalability:

Small Energy Storage - 1 to 10 kWh - Residential Use, Charging Stations

Purpose: Increase local consumption of electricity from decentralized PS, off-grid solutions, emergency PS.

Middle Size Systems - 10kWh to 1MWh - Buildings, commercial facilities, communities, Base Transceiver Stations

Purpose: load levelling, peak shift, solution for non-electrified regions etc.

Large Systems - Above 1MWh - Large power plants including renewable e.g. Mega-Solar, Wind, etc.

Purpose: load levelling, peak shift, optimization of energy generation, ancillary services and so on.
