OffGridBox - Water purification and energy supply mobile unit

OffGridBox is a rugged, mobile and modular unit that can provide clean water and solar energy to anyone, anywhere. Solar panels (3kWp) on the top and a water purification system are integrated into one system.

The stand-alone solution proves two services: access to electricity and clean water. One unit, placed near the village's water collection source provides around 400 families each with 20 liters of purified water and the recharge of a 40Wh battery pack, for $0.18 per recharge.The solar array on top can fast-charge (appr. 3 hrs) up to 300 individual battery packs which are brought back and forth by customers to recharge. The battery pack has a nominal capacity of about 10.000 mAh. The battery pack provides Tier 1 electricity, i.e. 3 LED lamps for 4 hours. Alternatively, the clients can use part of the electricity in the battery pack to charge their phone or a head light, play a radio, or even charge a hair cutter if they want to set up a barber shop or similar small business. The existing contaminated water is pumped or poured into the OffGridBox, the solar energy powered water purification system purifies the water and kills 99% of all bacteria. The modular unit can (and has been) equipped with desalination systems if the setting requires this process. This centralized unit can serve whole communities.
