Product Description

Meta Description (SEO): Off-grid solar powered milk tea shop in a 20ft container: 15 kWp solar, 60 kWh battery storage, 600–1,000 cups per day, plug-and-play and weatherproof.

Overview

The Off-Grid Flagship 20FT is our all-in-one answer for operators who want a complete milk tea business without depending on the local power grid. Built inside a standard 20-foot shipping container, it pairs a 15 kWp solar array with 60 kWh of LiFePO4 battery storage — enough to keep refrigerators, an ice maker, POS systems and lighting running through the day and night. The unit arrives factory-fitted, connects on site in about three days, and can trade anywhere the sun shines.

Key Features

  • True off-grid operation – runs a full store on solar and stored energy, with optional grid backup for extra peace of mind.
  • 60 kWh LiFePO4 battery with smart BMS – keeps the store running through the night and across cloudy days.
  • Up to 1,000 cups per day – complete professional milk tea station: sealing machine, ice maker, refrigerators, POS and LED menu board.
  • Factory pre-installed and plug-and-play – delivered ready to trade in about 3 days on site.
  • Cloud energy management – monitor generation, storage and consumption from your phone, anywhere in the world.
  • Built for outdoor life – insulated sandwich-panel shell, weather-sealed, engineered for -20°C to +50°C.
  • Optional ground-mounted solar array – adds up to 7 kWp of generation where space allows.

Ideal Use Cases

  • City street corners and plazas without easy grid access.
  • Highway service areas, tourist spots and national parks.
  • Campuses, resorts and private land where a kiosk must be self-sufficient.
  • Operators planning a premium, energy-independent brand image.

Sustainability & Business Value

Owners typically cut store electricity bills to near zero while gaining full independence from blackouts and unstable grids. Because every kWh is generated and stored on site, the store keeps trading during outages — a real revenue advantage. The long warranty on panels and battery, combined with a steel container shell that lasts decades, makes this a durable, resellable asset rather than a temporary kiosk.

FAQ

Q: Can it really run with no grid connection at all?

A: Yes. Solar generation plus 60 kWh storage covers a full day of normal operation, with 2–3 days of autonomy on stored energy alone.

Q: What happens during several cloudy days in a row?

A: The EMS manages load automatically and the optional grid backup (or a small generator port) can be used during extended bad weather.

Q: How long does installation take?

  • A: About 3 days on site: leveling, plumbing connection or tank fill, and system commissioning. No foundation or building permit complexity of a permanent store.
