Off-Grid Power, One Module at a Time — 400 W / 500 Wh
A compact, self-contained solar power module for off-grid use — combining solar generation, battery storage and power conversion in a single sealed unit. Start small and expand as your needs grow, without replacing what you already have.

🌿 Chemistry
LiFePO₄
The Techedge Modular Solar Unit brings solar generation, LiFePO₄ battery storage and a pure-sine inverter together in one sealed, weather-ready enclosure. It is designed to be installed and powered on without a specialist electrician for basic setup.
Its defining idea is modularity: begin with a single 500 Wh unit, clip on a second battery pack for more autonomy, and combine multiple units where more total power is needed — a clean path from one household to a larger off-grid system.
All values are design targets and subject to change.
Every unit ships with a 500 Wh base pack. For longer cloudy spells or higher nightly usage, an optional second 500 Wh pack clips on underneath the main unit — no rewiring, no tools, sealed against dust and rain.
500 Wh
For standard off-grid lighting needs and light loads.
1000 Wh
For areas with less predictable sunlight, or where backup depth matters more than upfront cost.
A single 400 W unit is designed to operate independently. Where more power is needed, additional units combine to increase total available capacity — supporting a path from a single household installation to a larger, multi-unit off-grid system, without replacing the original unit.
Lighting, fans, mobile charging and small appliances where grid power is unreliable or unavailable.
Dependable off-grid or backup power for shops, kiosks and shared community facilities.
Locations without practical access to grid infrastructure — deploy and power on.
Fast-to-deploy, identical units that scale by simply adding more — no custom sizing or specialist installation.
Current development focuses on lighting and light-load applications first, with higher-power loads (such as fans) planned as a subsequent phase of testing.
Designed for install-and-power-on operation, without requiring a specialist electrician for basic setup. Full installation guidelines will be published alongside the production release.
The Techedge Modular Solar Unit is in active development. We'd love to hear from technical and manufacturing partners, organisations interested in pilot or bulk deployment, and investors who want to back a scalable off-grid energy-access product.
