Because of the power outages in the Ukraine, a self-sufficient energy system with photovoltaics, a diesel generator and an XPB Basic Split with 35 kW output and 60 kWh storage capacity was installed at a farmer this winter.
The hybridization of a diesel generator with an energy storage device offers several advantages:
- Reduction of fuel consumption – especially good where it is difficult to get fuel supplies or the logistics costs of transporting them are high.
- Improved efficiency
- Improved power supply reliability
- Reduction of emissions
- Reduction of noise
- Reduction of maintenance costs
We test the complete system for 24 hours without a mains connection. The results can be seen in the graphs accompanying this article. Compared to a diesel generator that would be in continuous operation to cover the required consumption, a fuel reduction of 73 % could be achieved. Likewise, the generator was only 84% in operation
