Electricity for free? A few solar panels on the roof turn sun light into electricity. You don't have to pay more to Eskom than necessary.

A solar system can be either connected to the grid or off-grid. For load shedding cure you need also a pack of batteries. During load shedding you take energy from the PV panels and the batteries. All kinds of devices can be connected.

This type of system is called back-up system because it works like a Diesel generator and provides electricity during power failure. Another name is hybrid system because it combines the power of the grid with solar energy stored in batteries.

The systems does not only avoid total power failure during load shedding, it also cuts down electricity costs. Electricity costs are reduced by production of electricity by sun energy. The photovoltaic plant produces the energy for a fixed price per kWh and makes the owner more independent from Eskom and energy price increase. This kind of solar system provides cheap electricity and the sun power creates independence.

This system is a BMI 3000+  , the next bigger system is the BMI 5000+.

If you want a solar system to reduce costs only, a pure grid-tied PV system is a good alternative. By only installing the PV panels and no batteries you can save costs. The cost price of the system is lower and you save money during operation by avoiding costs for Eskom electricity. Have a look at our BMI 3000 or BMI 5000 if you are interested.

About the SMA inverter:

(source SMA)

The Sunny Island 6.0H/8.0H supports a wide range of on-grid and off-grid applications in the 3 to 25 kW range - from operation in remote off-grid areas to home energy management.

Furthermore, being a core element in the SMA Flexible Storage System for new and existing PV systems, it stores generated solar power and works with the Sunny Home Manager to manage home and commercial energy consumption intelligently.

Its high protection class, wide temperature range and exceptional overload capacity provide the kind of reliability needed for off-grid use. Intelligent load and energy management keeps the system running even in critical situations.


The Sunny Island offers flexibility in terms of combination with other equipment, which means that the system can be configured precisely to meet the applicable power requirements.

  • Choice of battery: The Sunny Island is compatible with many well-known brands of lithium-ion battery and all lead-acid batteries.
  • Can be retrofitted for single- and three-phase systems
  • Increase system size at any time with SMA multicluster technology
  • Increase system size at any time with SMA multicluster technology


In the SMA Smart Home, the Sunny Home Manager, with the Sunny Island, takes control of intelligent management between the PV system, appliances and storage systems as well as regulates all energy flows.

  • Comprehensive visualization in the Sunny Portal
  • Forecast-based charging
  • Simple planning using planning guidelines and Sunny Design
