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.

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.

Can a containerized Solar System be installed off-grid?

Off-Grid Installer have the answer with a containerized solar system from 3 kw up wards. Systems are fitted in new fully fitted containers either 20 or 40 foot depending on the size required.

Are off grid solar containers reliable?

Solar equipment is very reliable but occasionally parts may fail so there is need to monitor and solve any problems. Off Grid Solar container units guarantee security and reliability and allow the engineering team to complete installations in a few days rather than weeks.
