ENDRESS ESS 3/3 – portable 2.5 kWh battery system
The ENDRESS ESS 3/3 is a compact portable 230 V battery storage system with a 2.5 kWh lithium-ion NMC battery and 2.5 kW continuous output. Brief output up to 3.6 kW, two 230 V sockets, a rugged IP65 enclosure and a weight of just 25 kg make it suitable for mobile work, events and quiet power without a continuously running engine.
Key specifications
ENDRESS ESS 3/3: compact portable 230 V power
For trade work, filming, events or temporary use without a nearby socket, the ESS 3/3 supplies 230 V AC from a rechargeable lithium-ion battery. With 2.5 kW continuous output it can power suitable tools, lighting and equipment; the 3.6 kW peak is only available briefly.
The compact unit weighs approximately 25 kg, with a robust tubular frame, carrying handles and durable housing. The product specification lists IP65 protection. Battery operation generates no local engine exhaust and needs no continuously running generator, although equipment fans or electrical noise may still be audible.
A 2.5 kWh NMC lithium-ion battery supplies the outlets. According to the SEV product data, recharging takes approximately 2.5 hours. Battery energy and actual loads together determine runtime. The ESS 3/3 is a single-phase compact unit, not a 400 V three-phase energy storage system.
Benefits and technical highlights
230 V supply for compatible devices and power tools.
Output reserve for suitable brief surges, not continuous power.
Rechargeable lithium-ion storage for temporary applications.
Dust-tight and water-jet-resistant when used as specified.
25 kg with robust carrying handles.
Power suitable loads without fixed mains access.
Battery operation without a running petrol or diesel engine.
Charge display and battery protection management.
Features for real-world operation
Stored energy is different from output power
The 2.5 kWh figure represents stored energy. The system supplies up to 2.5 kW continuously within operating limits. The 3.6 kW peak is short-term only. Check motor starting currents before selection.
Quiet energy for sensitive environments
The ESS 3/3 powers suitable loads without an engine operating on site. It can help during indoor work, night construction, film shoots and smaller events. It is not automatically an uninterrupted UPS system.
Robust transportable enclosure
Its IP65-rated housing and tubular frame support professional mobile use. Despite the protection rating, plugs and charging connections must remain within their specified conditions.
Charging and operating schedules
A charging time of approximately 2.5 hours can support planning between sessions. Longer shifts require an accurate average load calculation. Automatic generator-hybrid features are not confirmed as standard on this compact model.
Safe AC supply
Use only compatible equipment. Earthing, supply configuration and any required residual-current protection must be checked for the intended operating situation.
Typical applications
Power for suitable tools and work lights.
Quieter supply for smaller professional loads.
Portable power for testing and assembly equipment.
Locally emission-free battery operation in suitable workplaces.
Energy for compatible mobile service equipment.
Short-duration use away from fixed mains connections.
How long will 2.5 kWh last?
At an average 500 W load, the simplified theoretical duration is about 5 hours; at 1 kW, about 2.5 hours – both before conversion losses and battery reserves. Actual runtime depends on use, charge level and temperature.
Technical specifications
Frequently asked questions about ENDRESS ESS 3/3
Which devices can the ESS 3/3 power?
Compatible 230 V equipment within a combined 2.5 kW continuous output. Consider starting current and total demand.
How long does one charge last?
At 500 W average draw, theoretical runtime is about five hours before losses; at 1 kW, about 2.5 hours.
Does the ESS 3/3 provide 400 V three-phase power?
No. The ESS 3/3 is a single-phase 230 V device.
Can it serve as an uninterrupted UPS?
UPS operation is not guaranteed. Critical loads require a suitable power and protection strategy.
Is indoor use possible?
Battery power creates no local combustion exhaust. Electrical safety, ventilation and environmental limits must still be observed.
How quickly can I recharge it?
The product specification gives about 2.5 hours under suitable charging conditions.
How does it differ from larger ESS D systems?
The ESS 3/3 is compact and single-phase. ESS D units provide larger capacities, three-phase output and options for generator hybrid integration.
Need higher power or three-phase output?
For higher demand, 400 V three-phase loads and generator hybrid applications, explore the larger ENDRESS ESS D battery systems. The ESS D 11/8 is a mobile three-phase solution, while ESS D 15/15, 15/30 and 30/30 serve larger sites.
