Enershare WTS Energy battery with intelligent BMS 9.9KWH - up to 26.4KWH

This is a battery for the home built from modules stacked vertically, like identical boxes placed one on top of the other. The "Energy" version is designed for autonomy, not for short power peaks: it holds the energy produced during the day by the panels and releases it slowly, over the course of the evening and the night. You can start with a small configuration and enlarge it later, adding modules, without replacing what already exists.

The capacity starts from 9.9 kWh, with 3 modules, and reaches 26.4 kWh, with 8 modules, the effectively usable energy being between 9.6 and 25.6 kWh. As a guide, a basic configuration covers the evening and night consumption of an ordinary home, and the large versions can carry the house through a whole cloudy day. The maximum current is 30 A continuous, with a peak of 50 A for 5 seconds, and the round-trip efficiency is a minimum of 96%. The dimensions grow with the capacity: from 800 x 650 x 260 mm and about 129.5 kg at 9.9 kWh, up to 1675 x 650 x 260 mm and about 312 kg at 26.4 kWh, so the space and a solid support must be planned; the modules are, however, plug and play, with a low mass per piece, mountable by a single person. The aluminium enclosure has IP65 protection and works between -10 and 55 °C, the service life exceeds 6,000 cycles, and the warranty is 10 years.

LiFePO4 modules of 3.3 kWh / 64 V; configurations from 3 modules (9.9 kWh, 192 V nominal, range 162-219 V) up to 8 modules (26.4 kWh, 512 V nominal, range 432-584 V). Maximum output current 30 A continuous, peak 50 A / 5 s, round-trip efficiency minimum 96%. Intelligent BMS with cell-level voltage and temperature supervision, active balancing and transmission of the state of charge and of the current limits to the inverter. Up to 6 stacks in parallel, that is about 153.6 kWh of total capacity; VDE 2510-50, IEC 62619, CE and UN 38.3 certifications.

Who it suits

Suitable for a house with high consumption or for a guesthouse, an office or a small commercial space, with a high-voltage hybrid inverter, which wants to fully cover the evening and night consumption.

Terms explained

• Usable energy: How much can actually be drawn from the battery; it is slightly below the nominal capacity, because a reserve always remains untouched, so that the cells last.
• Active balancing: The electronics redistribute the energy between the cells so that all are equally full, which extends the life of the pack.
• Self-consumption: Using in the house the energy produced by your own panels, instead of it being sent into the grid and bought back more expensively in the evening.

Technical specifications

Recommended applications

• Residential self-consumption with full coverage of the evening and night consumption
• Storage for guesthouses, offices and small commercial spaces on HV hybrid inverters
• Off-grid and hybrid systems with one to two days of autonomy
• Reducing the bill by charging on the night tariff and discharging at the daytime peak

Warranty

10 years

Technical details

Specifications confirmed from the manufacturer's datasheet

Enershare WTS Energy is the energy-type version of the Enershare modular high-voltage platform, built from LiFePO4 modules of 3.3 kWh with a voltage of 64 V each. The starting configuration uses 3 modules, that is 9.9 kWh at 192 V nominal, and can be extended up to 8 modules, respectively 26.4 kWh at 512 V. The voltage range varies accordingly, from 162-219 V for the minimum configuration to 432-584 V for the maximum one.

The usable energy covers the range 9.6-25.6 kWh. The maximum output current is 30 A in continuous operation, with a peak of 50 A for 5 seconds, and the round-trip efficiency is a minimum of 96%. Compared with the Power version, the Energy series is sized for long discharge cycles at moderate power, that is for maximising self-consumption and covering the night-time consumption.

The intelligent BMS supervises each cell on voltage and temperature, performs active balancing and communicates the state of charge and the current limits to the inverter. The aluminium enclosure has IP65 protection and a working range of -10...55 degrees C. The modules are plug and play, with a low mass per piece for installation by a single person. The dimensions start from 800 x 650 x 260 mm and about 129.5 kg for 9.9 kWh and reach 1675 x 650 x 260 mm and about 312 kg for 26.4 kWh.

Up to 6 stacks can be connected in parallel, which takes the total capacity up to about 153.6 kWh, enough for small commercial applications. The service life exceeds 6000 cycles, the warranty is 10 years, and the certifications include VDE 2510-50, IEC 62619, CE and UN 38.3.
