Solar Battery Charge Controllers



The Electrisol-SA solar charge controller provides intelligent battery management and charging circuitry to optimise the solar power that is stored in the battery bank. It protects the batteries against under or over charging and also prevent the battery bank from damage caused by deep cycle discharges. These features protects your investment battery bank to ensure maximum performance without compromising its lifespan.

High Performance Charge Controllers


The Studer VarioTrack High Performance Solar Charger is a Swiss product that is fully configurable and comes in two models, VT-65 and VT-80, in 65 or 80 A with up to 150 V input PV voltage range for battery voltages of 12, 24 or 48V. This regulator is optimally used in an Xtender system with synchronized battery management but also independently with other devices in any other PV system. With its excellent MPPT algorithm that automatically tracks the maximum power point and offering high efficiency, the VarioTrack provides a real added value to any solar installation

Village Solar Systems

To meet the growing demand for larger and more complex rural electrification systems, Electrilabs offers a new concept for micro-grids.

This concept brings a very robust solution, which is simple to implement while providing flexibility in both its design and management. A standard hybrid unit is at the core of the system and decentralized units can provide redundancy, storage service, power assistance, and interface with other renewable sources to the micro-grid.

This concept offers the following advantages :

  • Independence Each decentralized unit is independent from the rest of the system and can supply its own load in case of non-availability of the central unit. Each decentralized unit is also protected against the mal-functioning of other participants of the system if they have excessive energy consumption.

  • Energy and power allocations can be managed for each distributed group.

  • Flexibility Each decentralized unit can add its own power to what is allocated from the central unit.

  • Sharing Each distributed system with its own energy source can share the excess with other participants of the mini-grid on a “share the excess, keep the essential” principle. It also has a given quota of energy available from the mini-grid.

Anti-Islanding of grid-tied and/or Hybrid Solar Power Systems


Please note that legislation dictates that any system that is grid-tied and still capable of generating power when the grid power has failed, MUST present power from being pushed back into the grid while the grid has failed.

Many countries (including South Africa) have adapted the international standard DIN VDE 0126-1-1 in terms of the isolation of embedded power plants (grid-tied power generation systems) to prevent the islanding effect.
