Our system solutions
When considering going with solar, the very first decision to make is what capabilities you expect from your system. System capabilities and its functioning is determined by the typical type of inverter the system is designed around. Get this wrong and your system will never meet your expectations or be able to serve your needs. There are five main systems, with differentiating capabilities we will advise you on and design around.
Grid-tied System with no energy back up
This type of solar system must be connected to the utility grid by way of the inverter to function. It does not allow for battery power input but allows for a bidirectional flow of power between the solar system and the utility grid. The principal operation of this type of system is to reverse excess power generated during sunlight periods into the utility grid for credit and utilising grid power again during non-irradiance periods. However, if the grid fails the system shuts down.
Grid-tied hybrid system with bi-directional input for energy back up
This full hybrid type system has the capacity to be coupled to a battery bank and/or generator as additional power sources and can also be connected to the grid for bi-directional operations but will immediately disconnect from the grid when it fails and continue to function as an independent system.
Off-grid system with energy back-up capability
A basic off-grid system must be coupled to a battery bank as an integral part of the system and cannot interact with the grid for bi-directional operations. The system can charge and/or draw power from the battery bank but can however not be coupled to multiple standby power sources.
Hybrid off-grid system with multiple inputs
Hybrid off-grid systems have the capacity to be coupled to a battery bank as a standby power source to solar, but these systems can also not interact with the grid for bi-directional operations. The system can however have the grid coupled as an incoming power source to supply power directly to loads or to charge up the coupled batteries when no solar power is available. Depending on the type of inverter, these systems can often also be coupled to other standby power sources like wind power.
Variable frequency drive hybrid inverters for specific load application
Variable Frequency Drive (VFD) are mostly applied in the manufacturing and agricultural sectors. They are specific purpose type controller inverters that has been designed to drive standard 3-phase industrial motors (and pumps) through efficiently converting DC power from Solar PV into 3-phase AC Power of either 230V or 380V and have input for utility power to be able to switch between solar power and utility power sources.
POWER BACK-UP SYSTEMS FOR RESIDENTIAL, AGRICULTURAL AND COMMERCIAL USE.
Our Range of Battery Backup Power Systems, will ensure that you are protected from the consequences of ongoing power outages and provide you with backup power when you need it most
The way it works Battery Backup Systems work is quite simple and straightforward. The Batteries are charged with Eskom power when it is available. Then when there is a power outage or load shedding, the inverter will automatically switch over and supply your house, farm, or commercial operation with the energy stored in the batteries. Then, when Eskom’s power comes back on, the batteries will be charged again with Eskom power, so you are ready for the next power interruption.
Some of the man Benefits Backup Power Systems compared to Generators are:
- Much quieter than generators=
- Does not produce any air pollution
- Requires zero maintenance
- Can use Solar or Eskom power to charge batteries
- Instant Power Supply when there is a power failure
- Provides Clean safe power for expensive sensitive equipment (medical devices and electronics)

Energy Security Notice
Current Photovoltaic Solar system technology does not constitute or provide complete Energy Security even when over-designed and coupled to large capacity battery banks. Prolonged rainy/cloudy weather will eventually have the result of depleting stored energy which will result in the shutdown of the system. Where Energy Continuity and Security is important, an Off-grid system should be designed and configured to have a power source coupled to the system as a failsafe standby power alternative. – Utility or Standby Generator,
