Sierra Maria Project is a grid connected PV Plant that was designed with a triple purpose: 

-To inject the energy coming from the PV Fields into the grid during the day (conventional operation) 

-To inject the energy coming from the batteries during peak hours (BESS system- load leveling applications) 

-To supply with voltage the town of Sierra Maria and surroundings in case of a long grid absence (UPS System) 

The equipments- supplied by ENERTRON- that make up the PCU (Power Conditioning Unit) are:

-120 kW Three Phase Inverters, with dual operation, both as a Current Source as well as a Voltage Source, a special series of the ACEF-SOLAR. 

-Rectifiers for the battery charging during the night with the energy from the grid.
