Fronius
PV-Genset solution
Save fuel and energy costs with photovoltaics
The Fronius PV-Genset solution ensures optimum interaction between the photovoltaics and diesel generator. This saves fuel, lowers energy costs and ensures a stable and reliable power supply.
The advantages of the Fronius PV-Genset solution
- Coordinated solutions for every solar/diesel hybrid system
- Low energy costs
- Short payback period
- Very easy to integrate into existing systems
Fronius PV-Genset Easy
The Fronius PV-Genset Easy solution is ideal for backup applications with no more than one diesel generator. It ensures permanent stability for the entire system, making the best use of the PV power and not undershooting the minimum load of the diesel generator.
- Integrate PV systems quickly and easily into existing diesel systems
- Optimized for low-voltage applications with a diesel generator
Fronius PV-Genset advanced
With the PV-Genset Advanced solution, PV systems can be easily and quickly integrated into diesel systems in which several diesel generators are being used. The Advanced solution is primarily designed as a retrofit solution for multi-generator systems. The controller is the communication interface and assumes perfect control of the entire system. The PV system can thus relieve the workload of the diesel generators as much as possible and save costs. A striking feature of this solution is the combination and compatibility of strong partners such as ComAp, DEIF, Elum or Encombi.
- The retrofit solution for multi-generator systems
- Suitable for both low-voltage and medium-voltage applications
Fronius PV-Genset professional
The PV-Genset Professional is the fully integrated and harmonised solution for multi-generator systems. The controller is the communication interface and assumes perfect control of the entire system. This results in optimum interaction and relieves the workload from the diesel generators in the best possible way through the PV system. A striking feature of this solution is the combination and compatibility of strong partners such as ComAp or DEIF.
- The fully integrated solution for multi-generator systems
- Suitable for both low-voltage and medium-voltage applications
Maximum energy cost savings
Diesel generators are often associated with high and heavily fluctuating costs – which depend on the price of oil, transport costs and taxes. Depending on the region, the oil price is currently up to €2.5/KWh. In contrast, the cost of photovoltaics has fallen steadily in recent years and currently stands at €0.10/kWh on average worldwide.
As soon as the levelized cost of energy of a photovoltaic system undercuts those of a diesel generator, a PV-Genset system is a worthwhile investment.
The Fronius PV-Genset solution means we can make a significant contribution to saving energy costs, because every diesel kWh saved saves cash. As an installer, you can therefore impress your customers with a short payback period and low energy costs in the long term.
Intelligent control of the PV-Genset system
To ensure stable operation of the PV-Genset system, optimal control of the integrated components is essential. The Fronius PV System Controller is one of the elements responsible for this. It ensures the system runs smoothly, guarantees reliable yields and maximum energy cost savings.
The open structure also allows third-party components to be easily integrated into the system. Thanks to the Fronius Datamanager 2.0, Fronius components can be integrated into a control system with Modbus RTU or via TCP with the SunSpec Inverter Control Model.
The pV Genset solution in action
PV Genset system in Simbabwe
A tobacco factory in Zimbabwe has been using a PV system coupled with a 150 kVA diesel generator for several years. Following the completion of a capacity upgrade project, the system will ultimately be able to save up to 60 % in their previous daily fuel usage, which could work out to as much as 100 litres of fuel a day or more. The system was installed and commissioned by local Fronius System Partner James Davy, supported by OneStopSolar.
Technical data
Integrating photovoltaic systems into diesel generator-powered grids requires quick and reliable control of the entire system. The Fronius PV System Controller measures all power flows in the system, enabling it to control the PV power in the most optimum manner.
To provide additional protection for the generator, the Fronius measurement extension can be used as a quick reverse-power protection measure to perform an emergency shutdown.
The Fronius PV-Genset Advanced and Professional solutions are optimized for systems in which several diesel generators are being used. The solutions are suitable for both low-voltage and medium-voltage applications. Power outputs in the multi-megawatt range are therefore also possible.
