Technical FAQs 4

How much solar can a 20 foot container hold?

20 foot containers can expand from 3,000W of solar up to 6,000W. 40 foot containers can expand from 3,000W up to 12,000W of solar in the future. We love the strategically placed solar panels on top of the container roof - we've accomplished this secure mounting with our field tested RPS Scalable Ground Mount.

How many watts can a RPS container hold?

RPS packages up your shipping container with all of your batteries, power components, mounting etc. safety tucked away inside the container itself. 20 foot containers can expand from 3,000W of solar up to 6,000W. 40 foot containers can expand from 3,000W up to 12,000W of solar in the future.

Which battery bank should I choose for the Instant off-grid containers?

Choose between a GEL Deep Cycle Sealed Lead Acid battery bank or a next-gen Lithium Iron bank. See below from more details and pictures. Pre-configured by RPS engineers. 370W solar panels power the Instant Off-Grid Containers. Each panel measures 69.1”×40.9”×1.4”.

What type of container does RPS use?

RPS sources “one trip” containers (used for only a single trip overseas, very little wear, newer floors) and “watertight” containers retired after 10 years (may have some dents and welds but the container is watertight with a lot of life in it!). You have the option to choose which type of sourced container you’d like.
