Ecoult UltraFlex Indoor

UltraFLEX Indoor

The king of versatility

UltraFlex excels wherever there’s a need for high power and sustained energy.

It’s big enough to be serious – punching out 20 kW – but sized for pallet-jack delivery and able to find a spot on most sites.

Paired with a diesel generator, UltraFlex saves fuel. It charges and discharges quickly and continuously. The generator either doesn’t run at all, or runs beautifully at peak rated output. It can be given predictable operating conditions and decoupled from the load while the battery handles all the vagaries and fluctuations.

Self-contained and robust, UltraFlex can also be moved from site to site – it’s proven its worth by travelling from power-hungry building sites to music festivals that pump on, using the day’s solar energy long after sunset.

UltraFlex is fully and remotely monitored, so if you want to see how the site is running, just open your browser. Alerts are sent to you – and to us if necessary – to be acted on before they become problems.

Ecoult acknowledges the support and funding received from Australian Renewable Energy Agency (ARENA) under its “Emerging Renewables” and “Advancing Renewables” programs.
