Energy Storage Self Consumption

VOLTASOL - Self Consumption Energy System - Complete 10kWh Package

The all in one energy storage system with inverter, batteries and charger in one compact metalic cabinet. Aesthetically pleasant white cabinet that will stand out even inside the house, utility room, garage or the warehouse. 

The system stores energy in batteries, feeds power directly to the consumer unit reducing the dependence on the grid power. It uses the stored energy peak hours when the demand in high in the house.

More information will be added here shortly as this a brand new product, if you need to get more details please contact [email protected] (quoting in the subject the reference EES-Voltacon)


  • 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 10kWh, 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 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.

This energy storage system can provide power to connected loads by utilizing PV power, utility power and battery power and store surplus energy generated from PV solar modules for use when needed. When the sun has set, energy demand is high, or there is a black-out, you can use the energy stored in this system to meet your energy needs at no extra cost. In addition, this energy storage system helps you pursue the goal of energy self-consumption and ultimately energy independence.

Depending on different power situations, this energy storage system is designed to generate continuous power from PV solar modules (solar panels), batteries, and the utility. When the MPP input voltage of PV modules is within an acceptable range this energy storage system is able to generate power to feed the grid (utility) and charge the batteries. This energy storage system is only compatible with PV module types of monocrystalline and polycrystalline. Do not connect any PV array types other than these two types of PV modules to the energy storage system. Do not connect the positive or negative terminal of the solar panel to the ground.
