A power supply for your off-grid festival

The solution: Battery Swapping

There are already many sustainable solutions to get more out of an insufficient grid connection. Think of peak shaving with a battery, allowing even heavy equipment to run on a 3x80A grid connection. But in places without any grid connection, it’s still often difficult to provide a sustainable power solution. Many people still use diesel generators for this. But there’s a greener solution.

Greener has come up with something new: battery swapping. As the name suggests, this involves a solution with multiple batteries being swapped out for each other. We successfully implemented this at the Into The Great Wide Open festival. Here’s how it worked:

• We placed one battery at the remote festival location. This one served as a buffer to provide sustainable power to the entire location.
• At a nearby harbour, we charged another Greener battery using the available grid connection.
• As soon as the buffer on location started to run low, we drove the charged battery to there to discharge the charged power into the buffer.
• Then, we drove the second battery back to the harbour to recharge it.
