Voltacon All-In-One Energy Storage System with Photovoltaic for Your Home

Homegrown Energy in One Sleek Package 5kWh

Our sleek, all-in-one EES-Voltacon Storage System makes powering your home both easy on the wallet and easy on the eyes. This advanced self-consumption unit is a smooth and safe way to reduce your dependence on the grid, combining a 5.5kW inverter, charger, and 10kWh lithium battery in one compact metallic white cabinet.

Economically, solar power works when you replace the energy you would have purchased from the grid when demand is high in the house. Our system’s 10kWh lithium-ion residential battery storage lets you stock up on electricity generated by your solar power system and use the stored surplus when the sun goes down or whenever demand is high – plus provides peace of mind for emergencies if the grid goes out. The unit is scalable and can cascade more batteries to the existing inverter, cranking up the stored energy from 5kWh to 40kWh. For properties without solar panels, batteries can charge during off-peak hours using the low-cost tariff.

This state-of-the-art complete energy storage unit is ready to connect to the consumer unit of your house with simple plug and play installation, and takes up less than one square meter of floor space. Designed to generate continuous power from PV solar modules, batteries, and your utility, it charges the batteries and feeds back to the grid. With programmable multi-operation modes and user-adjustable battery charging, you are in control.

Compatible exclusively with monocrystalline and polycrystalline solar panels, the EES-Voltacon Storage System is your next step towards the ultimate goal of energy independence.


  1. Off-grid but with the grid as a back 
  2. Hybrid mode works with the grid in parallel, the inverter and grid will feed the AC loads.
  3. It exports energy back to the grid but this is adjustable from 0Watt to 5500Watt
  4. It can supply the AC loads connected to the grid and critical loads off-grid, combined capacity 5.5kW
  5. Timer Chargers. The ac charger is available for charging from the utility on demand when the tariff is cheaper


  • Self-consumption and feed back to the grid
  • Programmable supply priority for PV, battery or grid
  • User-adjustable battery charging, including timer
  • Programmable multiple operation modes, grid-tie, off grid, grid tie with back up 
  • Built-in time for various mode of on/off operation
  • Multiple communication for USB, rs232, Modbus, SNMP, GPRS and Wi-Fi
  • Monitoring software for real-time status and control
  • Enhance AC & Solar Charger up to 100Amps
  • Scalable Li-Ion battery, standard 5kWh, expandable 50kWh
  • Lithium ion batteries with over 8,000 cycles 
  • High surge discharge current uo to 3C
  • IP20 indoor use  only

For this system an array of the solar panel is required but it is not compulsory. For properties without solar panels, it is advisable to use the low-cost tariff to charge the batteries off-peak hours.
