Customer experiences
We successfully use the emost Butler S in a residential area where strict noise regulations and the lack of 63A/400V connections pose a challenge. This mobile battery generator reliably and quietly powers our mobile crane. With 25 kWh of capacity it provides a full working day of energy in island (off-grid) operation.
As an employee at JoLa Rent, I can report with great enthusiasm how successfully the emost Butler S has been integrated into our film and TV equipment fleet. It powered not only a wide range of vehicles for hair, make-up and wardrobe, but also our generators, mobile toilet units, Sprinter vans and the diverse needs of our film crew.
The emost Butler S has revolutionised our construction projects. As a building contractor I was sceptical at first, but after using it on several construction sites I am completely convinced. No noise, no exhaust fumes and always a reliable power supply – these are just some of the benefits.
