- Perform the simplest possible system management, in order to have the maximum reliability of such system.
- Perform irrigation to extract a maximum benefit as possible from selected panels.
- Slow down the loss of water levels during the year in order to reduce the need irrigation from other sources (aggregates, etc.).
- Perform more demanding management of the extended system (higher installed power of solar panels) to utilize almost all the available energy that panels can produce.
- Perform storage of excess energy during the day in batteries and utilization of stored energy during the night, or during cloudy weather.
- Enable the use of energy by other smaller consumers other than the pump.
- Avoid the loss of water levels during the year in order to reduce the need for other sources of irrigation (aggregates, etc.).
- Use of aggregates or other sources to be required only at critical moments during the summer.
Phoenix Contact equipment was chosen because of the knowledge and positive experience of colleagues from Nabla plus d.o.o., in working with it, as well as because of the help of colleagues from Phoenix C. Croatia and their technical assistance in solving the task given to them.

After the successful selection of equipment, the realization of the system started in the previously mentioned two phases.
In the first phase:
- the system met expectations and significantly reduced the need for aggregates and other water sources in the pond.
- the decline in the water level in the pond slowed down considerably, unlike when this system did not exist.
- the system delivered approximately 20,000 m3 of water in one year, consuming approximately 2 MWh of electricity produced by the solar system.
After the successful selection of equipment, the realization of the system started in the previously mentioned two phases.
In the second phase – the solar power system was increased by about 25%.
It is possible to operate the system direct via panels and drive via batteries.
The system stores excess energy in the battery during the day when there is excess energy, as well as during the morning and evening when the power produced by the solar system is too small to start the pump.
When the batteries are full and the power of the panel is too low to start the pump directly, the system starts working through the batteries.
Complete control of the system is performed using a Phoenix contact PLC which controls the battery charging and discharging system via a Phoenix contact relay.
