A container solar power station with no grid connection
A container solar power station with no grid connection is now built by LONGi, the Chinese solar panel maker. The product, called LONGi BLOCK, packs a complete solar power plant inside a standard shipping container, ships fully wired from the factory, and needs no grid connection, no foundation and no connection paperwork. LONGi built it for mines, military bases, construction sites and remote industrial parks, anywhere a grid connection is slow or impossible to arrange, the company states. The smaller, 20 foot container produces 119.6 kilowatts, a unit of electric power. The larger, 40 foot container produces 239.2 kilowatts from 368 modules, each rated at 650 watts and 24.1% efficiency, the share of sunlight a module turns into electricity. LONGi states the unit produces zero emissions while running and stays under 30 decibels of noise, a measurement of how loud a sound is.
How fast it unfolds into a working power plant
A crew of 6 unfolds a LONGi BLOCK container into a running power plant in about 3 hours for the smaller size and about 4 hours for the larger one, pv magazine and PV Tech report. PV Tech describes the process as a single button press. Every module must level with its neighbors to within 3 centimeters, and no more than 30 centimeters across the whole site, for the system to work.
How the container holds up in wind and water
A LONGi BLOCK container is rated for wind speeds up to 21 meters a second, the standard unit for wind speed, in normal operation, rising to 56 meters a second with an optional storm reinforcement kit, pv magazine and PV Tech state. The container structure alone withstands up to 34 meters a second without the kit.
All 3 figures describe the same LONGi BLOCK container at increasing levels of reinforcement.

The container, the module and the inverter each carry a separate IP rating, a 2 digit code for how well a sealed enclosure keeps out solids and water. pv magazine states the container is rated IP54, sealed against dust and splashing water, the same tier as a sheltered outdoor control box. The solar modules carry IP68, built to survive continuous underwater immersion, 2 full tiers higher than the box that holds them, a comparison drawn from reading the rating figures against the standard definitions, since neither source states it directly. The weakest sealed part of the system is the shell, not the electronics inside it.
LONGi backs the container with a 2 year warranty. The solar modules carry a 15 year product warranty and a 30 year power output warranty, pv magazine states.
All 3 figures are warranty periods for different parts of the same LONGi BLOCK unit.

No named site is yet running one
No source checked for this article names a real site anywhere already running a LONGi BLOCK container. LONGi has shown the product at 3 trade events in 2026, SNEC in China, the Africa Energy Forum, and its European debut at Intersolar Europe in Munich, PV Tech states. A similar product from a different company already has a result to point to, 3 forty foot solar containers running at an iron ore mine in the Pilbara region of Western Australia, displacing 258,000 liters of diesel a year with a 3.2 year payback, Solar Container Kit states. That result belongs to a different product, not LONGi BLOCK, and shows what a similar system can already do, not what this container has done.
