GRID-CONNECTED SELF-CONSUMPTION INSTALLATION WITH STORAGE IN LLEIDA
This represents a radical power increase in an ESS installation, going from 30 to 90 kW, with a 20 kW grid backup.
The initial installation already had three 10 kW inverters in a three-phase configuration, with a 25 kW solar contribution and a 15 kW lithium battery. When expanding to include a manure management system, the main engine of this installation alone is 55 hp (approximately 40 kW), so a system capable of providing at least double this power is needed, especially for start-up. This is further complicated by the fact that the installation not only powers this system but also the operation of several farms and a regularly used single-family home.

This industrial self-consumption system is a clear example of what is known as an ESS (Energy Storage System). In other words, it’s a system for supplying and storing solar energy, combined with a grid connection. A strict and calculated operating protocol is established, where direct photovoltaic solar energy (during periods of sunlight) is the primary source. If there is sufficient photovoltaic power, the system will be powered directly by the sun. Secondly, if there is no solar energy available, or if it cannot meet the total consumption at that moment, the battery kicks in, providing the additional energy needed to cover 100% of the energy demand. Conversely, if solar production exceeds consumption, the excess energy is fed into the battery. Finally, if there is no solar production and the battery is insufficient to meet the demand, a contactor will open, switching to the grid supply. This ensures that energy consumption is always covered at the best possible price.
Installation elements:
- 150 solar panels of 600Wp.
- 9 isolated 10 kW inverters
- 3 x 25 kW grid inverters
- 6 Lithium batteries of 16.2 kW
