Bluetti EP2000 Inverter

The Bluetti EP2000 EnergyPro 20K inverter is a high-performance three-phase hybrid inverter designed for setting up a domestic or commercial energy storage system. The model is designed for use with Bluetti B700 battery modules and enables the creation of a fully-fledged system for emergency power supply, solar power storage and the autonomous operation of a house or facility.

The Bluetti EP2000 belongs to the category of whole-house ESS solutions, i.e. energy supply systems for the entire house. It is not a portable charging station in the conventional sense, but a stationary hybrid inverter that works in conjunction with batteries, solar panels and the mains supply. Such a system is suitable for residential properties, offices, small commercial premises, technical rooms and scenarios where a reliable, high-power emergency power supply is required.

The system’s output depends on the number of B700 batteries connected. With two batteries, the system delivers 10.5 kW; with three , 15.5 kW; and with four or more batteries, up to 20 kW of output power. This capacity enables the system to power not only basic loads but also high-power domestic appliances, pumps, heating systems, ventilation systems, kitchen appliances and other essential loads.

The system operates on a three-phase mains supply of 230 V/400 V at a frequency of 50 Hz. The phase configuration is specified as 3L/N/PE; therefore, the EP2000 is specifically designed for premises with a three-phase power supply. This is important for residential and commercial properties where the load must be distributed evenly across the phases and the operation of more powerful appliances must be maintained.

B700 battery modules are used for energy storage. One module has a capacity of 7.37 kWh (7,372.8 Wh), and the system’s standard configuration with 2–7 batteries offers a total capacity of 14.7 to 51.6 kWh. This energy storage system is suitable for providing extended emergency power to the home, operating via solar panels and reducing dependence on the public electricity grid.

Scalability is provided for large-scale installations. The documentation states that, when several systems are connected in parallel, an output power of up to 40 kW or 60 kW and a capacity of up to 154.8 kWh can be achieved. This makes the EP2000 an attractive solution not only for private homes but also for larger-scale energy applications.

The solar component of the system is one of the model’s key advantages. The maximum power of the PV input per inverter is 30 kW. The MPPT voltage range is 160–850 V, the nominal value is 500 V and the maximum current per MPPT input is 30 A. There are 2 independent MPPT inputs, which enable more efficient operation with different groups of solar panels.

The inverter’s efficiency is up to 98 per cent. High efficiency is important for energy storage systems, as it reduces conversion losses and helps to extract more usable energy from the batteries and solar panels. This is particularly relevant for the day-to-day operation of the system in energy-saving mode or in off-grid mode.

The Bluetti EP2000 supports operation in both on-grid and off-grid modes. This means that the system can be operated either whilst connected to the mains supply or in stand-alone mode. In the event of a mains power failure, the inverter switches to the emergency power supply in less than 10 ms, ensuring that essential appliances continue to run without any prolonged interruption.

The system is well suited to scenarios where an emergency power supply is required for the entire house. It can maintain the operation of the fridge, lighting, router, pumps, heating system, household appliances, electronics and other critical devices. With a sufficient number of batteries and a correctly sized solar array, the EP2000 can significantly reduce dependence on the mains supply.

The inverter has an IP65 protection rating and is therefore better protected against dust and moisture than conventional indoor units. The operating temperature range is between -20 °C and +60 °C, with a noise level of up to 50 dB. This allows the system to be used in a variety of installation conditions, particularly in plant rooms or sheltered outdoor areas.

USB, Wi-Fi and Bluetooth are available for communication and control. This enables the inverter to be integrated into a modern monitoring system, as well as allowing monitoring of operating parameters, battery status, solar power generation and consumption. This feature is useful for homeowners and businesses requiring real-time monitoring of their energy system.

The inverter measures 670 × 280 × 460 mm and weighs 60 kg. These are stationary units that require professional installation, the selection of batteries and solar panels, protective devices and connection to the mains supply. For such a system, professional installation is essential, taking into account the three-phase connection and the permissible loads.

The Bluetti EP2000 EnergyPro 20K is the solution for anyone who needs a powerful, scalable and durable system for energy independence. The inverter combines an output power of up to 20 kW, a solar input of up to 30 kW, operation with B700 batteries, a three-phase connection, a switchover to backup in less than 10 ms, IP65 protection, an efficiency of up to 98 per cent and a 10-year warranty. This is a good option for homes and properties that require not just an emergency power supply, but a fully-fledged hybrid energy system.
