The combined use of both devices allows for the creation of hybrid systems that combine photovoltaic generation and energy storage, without the need for additional photovoltaic inverters. Furthermore, the Ingeteam hybrid inverter, in combination with the BYD battery, enables operation in off-grid mode, backup (UPS) mode, and self-consumption mode. Thus, in grid-connected installations, it becomes possible to store the solar energy generated during the day for consumption at night, achieving the highest possible self-consumption rates without the risk of power outages during grid failures, thanks to the backup (UPS) mode capability.
During the certification process, BYD implemented a novel battery capacity calibration system, which allows for more precise and controlled monitoring of the battery's state of charge. Both companies took this opportunity to incorporate this functionality into the Ingeteam inverter and verify that the system works perfectly.
BYD's high-voltage lithium iron phosphate (LiFePO4) battery, with capacities of 5.1 kWh and 6.4 kWh (depending on the model), is designed for residential and commercial use. It stores electrical energy and optimizes energy efficiency in the installation by stabilizing the power supply.
Meanwhile, Ingeteam's inverter allows both a photovoltaic array and a battery bank to be connected to a single unit, reducing the overall system cost. This single-phase inverter, available in 3 or 6 kW versions, is transformerless and designed for residential and commercial installations.
