Ingeteam and BYD have tested and certified at their respective R&D laboratories the compatibility of BYD’s high voltage Battery-Box H 5.1 and 6.4, and Ingeteam’s INGECON® SUN STORAGE 1Play hybrid solar-plus-storage inverter.

The coupling of Ingeteam’s inverter and BYD’s batteries is a complete hybrid system to capture and maximize the use of the solar resource. The versatility of the Ingeteam hybrid inverter in combination with BYD’s HV battery, permits to operate in stand-alone mode, back-up (UPS) mode or self-consumption mode. Thus, on-grid systems can store the solar energy during the day to consume it at night without risk of a power outage in case of a grid blackout, prioritizing the maximum self-consumption ratio at the same time.

During the certification process, BYD implemented a new battery capacity calibration system to improve the measuring and control of the state of charge of the battery. This newest feature was also implemented and certified within the Ingeteam inverter.

BYD’s LiFePO4 high voltage battery, with its 5.1 kWh and 6.4 kWh of capacity -depending on the model-, has been conceived for residential and commercial use, storing the electric energy and optimizing the installation’s energy efficiency thanks to the stabilization of the power supplied.

For its part, the Ingeteam hybrid inverter makes it possible to connect a PV array and a battery bank to the same unit, thereby reducing the cost of the system as a whole. This is a 3 or 6 kW single-phase transformerless inverter, to address residential and commercial installations.
