Technical FAQs 4

What is a mobile solar PV container?

High-efficiency Mobile Solar PV Container with foldable solar panels, advanced lithium battery storage (100-500kWh) and smart energy management. Ideal for remote areas, emergency rescue and commercial applications. Fast deployment in all climates.

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 is HJ mobile solar container?

The HJ Mobile Solar Container comprises a wide range of portable containerized solar power systems with highly efficient folding solar modules, advanced lithium battery storage, and smart energy management.

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.
