ENDRESS ESS D 11/8 – mobile battery energy storage
The ENDRESS ESS D 11/8 is a professional mobile battery energy storage system with 400 V three-phase and 230 V single-phase output. Its 8 kWh usable capacity, 11 kW continuous output and up to 13 kW peak output provide quiet, locally emission-free power for tools, event technology and mobile workstations. The robust IP65 enclosure, integrated wheels and touchscreen make it practical for changing job sites.
Key specifications
Mobile battery storage with 400 V – power without a running generator
The ENDRESS ESS D 11/8 combines portable power with the output of a professional three-phase system. Providing 400 V three-phase and 230 V single-phase AC, it offers an alternative to a conventional generator where equipment needs to run without a continuously operating combustion engine. This means no combustion exhaust at the point of use and less noise – valuable for indoor work, overnight construction, events and sensitive locations.
The lithium-ion NMC battery provides 8 kWh of usable energy and powers equipment at up to 11 kW continuous output, with up to 13 kW available for peak demand. Actual operating limits depend on phase loading, inrush current and state of charge. One CEE 400 V / 16 A output and three 230 V sockets support suitable power tools, pumps, lighting and audiovisual equipment.
Recharging is designed for mobile operation: approximately 2 hours using 400 V or 5 hours using 230 V, according to the manufacturer. The touchscreen displays charge status, input and output figures and operating information. The dust-tight, water-jet-resistant IP65 enclosure, built-in wheels and extendable handle simplify movement between locations.
Benefits and technical highlights
Suitable applications
How long does one battery charge last?
Runtime depends on the actual load. As a rough calculation, divide the 8 kWh usable capacity by the average power consumption in kW to estimate hours of operation. At an average of 2 kW, this would be around 4 hours before conversion losses and reserve capacity. Inrush current, load profile, temperature and state of charge can affect the result.
Technical specifications
Frequently asked questions about the ENDRESS ESS D 11/8
Can the ENDRESS ESS D 11/8 power 400 V three-phase equipment?
Yes. It has a CEE 400 V / 16 A output and three additional 230 V / 16 A sockets. Continuous and peak output, phase loading and the equipment requirements must be checked.
How long will the mobile battery storage system run?
Runtime depends on average power consumption. At a theoretical constant 2 kW, 8 kWh corresponds to roughly 4 hours before losses and reserve capacity; actual runtime may be shorter.
How long does it take to recharge?
ENDRESS states approximately 2 hours with a suitable 400 V supply and 5 hours at 230 V, under appropriate charging conditions.
Can I use the ESS D 11/8 indoors?
Battery operation generates no combustion exhaust at the point of use. Site conditions, temperature limits, electrical protection and the manufacturer's safety instructions still apply.
Can it be charged from solar power?
ENDRESS mentions charging via a suitable balcony PV / solar arrangement. The external charging method and compatibility must be checked; a direct solar input is not guaranteed here.
Is the ESS D 11/8 a diesel generator?
No. It is a rechargeable lithium-ion NMC battery storage system that supplies power without its own combustion engine.
