| Model | Capacity | Power | Weight | Charging time |
|---|---|---|---|---|
| ESS D 15/15 | 15 kWh | 15 kVA | 700 kg | 1.4 h |
| ESS D 15/30 | 15 kWh | 30 kVA | 850 kg | 2.4 h |
| ESS D 30/30 | 30 kWh | 30 kVA | 900 kg | 1.8 h |
Ideal for combined operation
with an ENDRESS RENTAL Line RS!
The three-phase energy storage systems can not only be used completely autonomously, but also in combination with an ENDRESS RENTAL Line RS power generator. This enables intelligent load management and reduces the operating hours of the power generator. This results in lower operating costs and fewer maintenance intervals.
There is an efficient principle behind the combined operation: when the generator is running, it supplies the connected consumers with power and simultaneously charges the batteries installed in the energy storage system.
The interconnected operating unit can be conveniently activated by remote start, so that the generator can be switched on automatically when a certain power reduction or discharge depth is reached.
ESS D 11/8 - Mobile three-phase current for professional applications
Three-phase current up to 13 kW (peak power) with a usable capacity of 8 kWh is now available for mobile use.
How does it work? With the ESS D 11/8!
The ESS D 11/8 is the ideal power source for indoor and outdoor use. Thanks to its IP65 protection rating, the device is protected against dust and water jets. A rust-proof alloy also protects the energy storage unit from external influences.
There are no restrictions when connecting consumers, as the ESS D 11/8 is equipped with both a CEE 400 V / 16 A and three standard 230 V / 16 A sockets. With a total output of over 1,000 W, you can operate one or more devices for up to 7 hours.
Once the lithium-ion batteries are empty, they can be recharged in just 2 hours by connecting them to a 400 V socket. Charging is also possible via the normal power grid or via an optional PV panel. The ESS D 11/8 is conveniently operated via touchscreen.
In short: The ESS D 11/8 is an 80 kg lightweight, mobile energy storage system with three-phase and alternating current for continuous load and high performance.
