Solar-Powered Container House — Mining Project in Shandong, China
A mining project in Shandong Province, China needed a self-contained modular building that could be delivered quickly, kept simple to maintain, and run reliably in a location where grid power is not always dependable. The brief called for three rooms and a lobby under one roof, with on-site work kept to a minimum.
The project drawings specified prefabricated container units on a client-prepared foundation, a zinc-aluminium roof carrying solar panels, and full services: lighting, 13 A socket outlets, distribution boards, CCTV, emergency call points, fire protection and split air-conditioning. FONZE HOUSE engineered the quick-built modular house around these drawings: a factory-welded galvanized steel frame with insulated panels, a PV-ready roof, and an off-grid power package — solar array, inverter and LiFePO4 battery — with mains backup.

Case Study
Factory-built, solar-powered, ready on site
The house is built as factory container modules on a hot-dip galvanized steel frame, with roof trusses from hollow sections and a zinc-aluminium pitched roof fitted with a galvanized solar mounting frame. All exposed metal is treated to the drawing note — cleaned, primed with two coats of zinc phosphate and finished with two coats of enamel.
Energy comes from the roof. For each unit, the solar system comprises five 600 Wp PV panels (2,294 × 1,134 mm), a 6 kW off-grid inverter, a hot-dip galvanized mounting frame and a custom distribution board, storing power in a 5 kWh LiFePO4 battery (51.2 V, 100 Ah) housed in a Power Cube cabinet. The unit runs on solar and battery first, and switches to mains supply when needed — it can also be wired to run on mains only.
Inside, each room is fitted with a 9000 BTU wall-mount split air-conditioner, 5 W LED luminaires, 13 A socket outlets and a fire-protection set with 2 kg CO2 extinguishers. The electrical design follows a three-phase layout from the incoming board to lighting, socket and A/C distribution boards, with CCTV (including ceiling fisheye cameras), emergency call switches and network points.

Power package
Each unit stores energy in a 5 kWh LiFePO4 battery (51.2 V, 100 Ah) housed in a Power Cube cabinet, paired with a 6 kW off-grid inverter and five 600 Wp roof panels. The system runs on solar and battery first and switches to mains backup when needed — and can also be wired to run on mains only.
