Enershare WTS Power battery with intelligent BMS 5.52KWH - up to 13.80KWH

It is a battery built from modules that stack one on top of the other, like drawers, over a base unit with the supervision electronics. You start with two modules and add others later, as consumption or budget grows, without changing what you have already bought. The "Power" version is designed for situations where you need a lot of power for a short time — starting a heat pump, a motor or a charging station — not necessarily for long autonomy.

The minimum configuration is 5.52 kWh and, by adding modules of 2.76 kWh, you can reach 8.28, 11.04 or 13.80 kWh, with effectively usable energy between 5.36 and 13.40 kWh. The maximum current is 25 A continuous, with a peak of 50 A for 5 seconds, exactly what loads that start hard require; the round-trip efficiency is a minimum of 96%, so the losses are small. The battery also grows physically with the number of modules: from 625 x 650 x 260 mm and about 90 kg at 5.52 kWh, up to 1150 x 650 x 260 mm and about 195 kg at 13.80 kWh, so a solid wall or floor area must be provided. The aluminium enclosure has IP65 protection and works between -10 and 55 °C, so it also accepts a garage or an unheated outbuilding. If later you need much more capacity, up to 6 stacks can be connected in parallel, that is approximately 80.4 kWh usable, with a 10-year warranty.

LiFePO4 modules of 2.76 kWh, configurations of 2 to 5 modules: 204.8 V nominal (range 172.8-233.6 V) at 5.52 kWh, up to 512 V nominal (range 432-584 V) at 13.80 kWh. Maximum output current 25 A continuous, peak 50 A / 5 s, round-trip efficiency minimum 96%. Integrated BMS with voltage and temperature monitoring at cell level, balancing and communication with the inverter for limiting the currents and reporting the state of charge. On-grid, on-grid with backup (EPS) and off-grid regimes; VDE 2510-50, IEC 62619, CEC, CE and UN 38.3 certifications.

Who it suits

Suited to a house with a high-voltage hybrid inverter and loads that start hard (heat pump, booster pump, charging station), where peak power matters more than long autonomy.

Terms explained

• High voltage (HV): The battery works at a few hundred volts and connects only to hybrid inverters designed for this type of battery; it is not compatible with 48 V inverters.
• Peak current: The additional power the battery can give for a few seconds, needed at the moment of starting motors and compressors.
• EPS (backup): The function through which, when the grid goes down, the battery keeps supplying the important circuits in the house.

Technical specifications

Recommended applications

• High-voltage residential storage coupled to HV hybrid inverters
• Applications with high, short-duration power peaks (heat pumps, motor starting)
• Backup systems with island operation for homes
• Staged expansion of the storage capacity, module by module, without replacing the installation

Warranty

10 years

Technical details

Specifications confirmed from the manufacturer's datasheet

Enershare WTS Power is a modular high-voltage battery, built from LiFePO4 modules of 2.76 kWh that stack vertically over a base unit with a BMS. The minimum configuration is 2 modules, that is 5.52 kWh at 204.8 V nominal, and by adding modules you reach 8.28 kWh, 11.04 kWh and 13.80 kWh, the last version working at 512 V nominal. Each step has its own voltage range, from 172.8-233.6 V for the base configuration up to 432-584 V for the maximum configuration.

The usable energy goes from 5.36 kWh to 13.40 kWh, depending on the number of modules. The maximum output current is 25 A in continuous operation, with a peak of 50 A for 5 seconds, which makes the Power version suitable for short and intense loads (motor starting, heat pumps, charging stations). The round-trip efficiency is a minimum of 96%.

The integrated BMS monitors the voltage and the temperature on each cell, manages the balancing and communicates with the inverter for limiting the currents and reporting the state of charge. The aluminium enclosure has IP65 protection rating and an operating range of -10...55 degrees C, so it also withstands mounting in unheated spaces. The dimensions grow with the number of modules, from 625 x 650 x 260 mm and about 90 kg for 5.52 kWh, up to 1150 x 650 x 260 mm and about 195 kg for 13.80 kWh.

The system can be expanded up to 6 stacks in parallel, that is up to approximately 80.4 kWh of usable energy. It is certified VDE 2510-50, IEC 62619, CEC, CE and UN 38.3 and works in on-grid, on-grid with backup (EPS) and off-grid regimes, with a 10-year warranty.
