This embedded generation system in Johannesburg, Gauteng is connected to the Eskom grid. 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 SolarEdge inverter:

(source SolarEdge)

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability.

The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage, regardless of the number of modules in a string or environmental conditions.

A proprietary data monitoring receiver has been integrated into the single phase solar inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge monitoring portal for performance analysis, fault detection and troubleshooting of PV systems.

The single phase inverter can be fitted with a seamlessly attachable cabling duct for managing the installation wiring. The inverters are lightweight and can be installed by a single person on a supplied bracket.

 Single Phase Inverter Feature highlights:

  • Solar inverters specifically designed to work with power optimizers
  • Superior efficiency (>97%)
  • Excellent reliability with standard 12 year warranty (extendable to 20 or 25 years)
  • Small, lightweight and easy to install
  • Built-in module-level monitoring receiver
  • Communication to internet via broadband or wireless ZigBee
  • IP65 / NEMA 3R – Outdoor and indoor installation
