The use of both items of equipment together makes it possible to create hybrid systems that combine PV power generation with energy storage, with no need to add additional solar PV inverters. Moreover, Ingeteam's hybrid inverter, in combination with the BYD batteries, allows for operation in off-grid, back-up (UPS) and self-consumption modes. Thus, for grid-connected systems, the solar energy generated during the day can be stored for night-time consumption, giving the highest possible self-consumption ratios and, thanks to the possibility of operating in backup mode (UPS), the power supply is maintained in the event of a grid outage.
The BYD high-voltage lithium iron phosphate (LFP) batteries, with capacities ranging from 5.1 kWh to 22.1 kWh (depending on the model) are designed for residential and commercial use. Their patented modular plug-in design makes it possible to connect the different battery modules with no need for wiring, making installation incredibly quick and easy. Specifically, the following BYD battery models are compatible with the Ingeteam hybrid inverter: HVS (5.1, 7.7 and 10.2) and HVM (8.3, 11.0, 13.8, 16.6, 19.3 and 22.1).

For its part, the Ingeteam inverter makes it possible to connect a battery bank and two PV arrays to the same unit, thereby reducing the overall cost of the system. It features two PV inputs, each of which has its own maximum power point tracking system (MPPT), allowing it to manage up to 11.5 kW of power from the solar panels which can be roof-mounted with two orientations. This 3 or 6 kW single-phase transformer-less inverter has been designed for use in residential and commercial installations alike. Moreover, this inverter is supplied with the EMS control system as standard, allowing it to deploy advanced functionalities with no need to add another device for additional control.

The monitoring of the hybrid system is carried out easily and intuitively thanks to the software developed by Ingeteam: Ingecon Sun Monitor, which allows access to all the data of the photovoltaic installation, the batteries, etc., so that the user has total control over his/her electricity consumption.
