Residential Self-Consumption

The self-consumption installation is made up of 45 300W BENQ monocrystalline solar panels and high-efficiency PERC technology.

The conversion from direct current to alternating current is done by a SMA Tripower 12 kW three-phase grid inverter, and the battery charge and discharge management is carried out by three 4.4 SMA Sunny Island 6.0H-12 battery inverters. nominal kW each.

The solar energy generated and not self-consumed is instantly stored in 3 BYD 10 kWh lithium batteries, which store a maximum of 30 kWh useful energy, and allow the downloading of a nominal power of 13.2 kW three-phase thanks to the 3 battery inverters installed, and in periods of 30 minutes up to 18 kW three-phase instantaneous power.

The instantaneous power is added provided by the 12 kW grid inverter, which means that in times of high irradiation and with the battery full, up to 25 kW of instantaneous power can be supplied from the solar installation.

The system has the complete SMA Sunny Home Manager 2.0 monitoring system that allows you to control all the operating parameters of the system and even allows demand management with the home appliances based on the weather forecast.

At the same time, an underfloor air conditioning system consisting of two Panasonic aerothermal pumps of 8 kW thermal each has been installed. This aerothermal system allows working with a COP of 5 in most times of the year, which means that for each electrical kWh consumed we are capable of delivering up to 5 thermal kWh.

The installation offers a total energy autonomy of more than 80%.
