Manufacturer · Guzhen, Zhongshan · China
GOFA has built luminaires in Guzhen since 2015. ranneen builds lithium storage in the same town. Same ownership, same export desk, one order, one container.
Two manufacturers, one owner
Outdoor solar and mains LED for streets, façades, gardens and industrial interiors — 144 product families across the 2024 indoor and 2025 outdoor catalogues.
LFP batteries, hybrid inverters and all-in-one systems from 2 kWh to 80 kW, built around grade-A cells with a TDT smart BMS and app monitoring.
Why buy from the factory
Private-label on both lines: your logo, casing colour, screen languages, packaging and manual. A new brand competes with the trust your name already carries; a factory behind your label doesn't.
Portable units, 25.6 V and 51.2 V batteries, hybrid inverters and cabinets up to 80 kW — one product family, one comms set. A home backup and a commercial install ship on one order.
The BMS communicates over CAN and RS485, selectable on the app, PC or touch screen — so ranneen fits the inverters already on your shelf rather than forcing a change.
Sustainability
Every ranneen system can replace a diesel generator or a lead-acid bank with clean, long-life lithium — helping your customers cut fuel, emissions and running cost.
Trade & private-label
We sell through the trade, not around it. Your brand on both lines, factory-direct pricing on request, and one export desk for lighting and storage together.
