Technical FAQs 4

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”.

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.

What is a microgreen containerized energy storage solution?

The core technology used in Microgreen containerized energy storage solutions are top quality Lithium Ferrous Phosphate (LFP) cells from CATL. CATL ’s 280Ah LiFePO4 (LFP) cell is the safest and most stable chemistry among all types of lithium ion batteries, while achieving 6,000 charging cycles or more. CATL serves global automotive OEMs.

What is the capacity of a CATL battery?

CATL serves global automotive OEMs. It is the global volume leader among Tier 1 lithium battery suppliers with plant capacity of 77 GWh (year-end 2019 data). Range of MWh: we offer 20, 30 and 40-foot container sizes to provide an energy capacity range of 1.0 – 2.9 MWh per container to meet all levels of energy storage demands.
