Density Beyond the Grid

by Arkadiusz Klimczyk, Head of Product Delivery R&D, ex. InPost

In an autonomous locker, connectivity, locks, sensors, interface and lighting all draw on one limited energy budget. That makes off-grid a different hardware architecture — not a locker without a cable.

  • Why density should follow demand, not the nearest power connection
  • What it takes to engineer a locker around an energy budget
  • How to match power models to locations instead of going off-grid everywhere

Which lockerfits your needs?

Different locations need different power models. All three run on the same 7-Module Software Suite — here is how they compare.
