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 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.
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 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.
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.
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.
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.To the reference
