01

HOW SOLGEN WORKS

Smart, Self-Contained Hybrid Power

SolGen combines solar, battery storage and a Stage V HVO generator into one compact, mobile unit. Engineered for off-grid reliability, it's ideal for construction, rail, events, and infrastructure—where fuel savings, renewable energy sources, and clean energy efficiency matter most.
Solar panels auto-deploy on arrival, and LiFePO4 battery storage keeps power flowing even overnight or in low sunlight. Smart controls and a remote monitoring portal give you live visibility of fuel savings, battery status and generator activity from anywhere.

02

HOW SOLGEN WORKS

Only Runs When You Need It

Unlike traditional diesel generators that burn fuel 24/7, SolGen solar power works on demand. Power is drawn from clean solar energy — directly or via batteries. The generator kicks in only when needed, cutting fuel use by up to 90% and slashing emissions, ensuring a continuous power supply.
The backup generator is Stage V compliant and HVO-ready, so even the fuel it does use produces significantly lower emissions than standard diesel. Quiet hours can be programmed to keep the generator silent overnight — ideal for residential, ULEZ or noise-sensitive sites.

03

HOW SOLGEN WORKS

Seamless Power. Simple Setup.

The hybrid system automatically switches between solar energy, battery and generator power. Just plug it in and go. SolGen hybrid solar-powered units are available in both mobile and static options, making them the smartest off-grid solution on the market.
Every unit is designed and manufactured here in the UK, with GPS tracking for added security and full setup support included. Whether you need a unit for a few weeks or a multi-year project, SolGen is available to buy or hire to suit your timeline.

CASE STUDIES

THE STUDY

A 63kVa Static SolGen powered the Cambridge high usage site with 3 offices units, a toilet block , a dry room and water browser. On a 24 Hours, Mon to Sun site. Initially without any power management controls, power was being consumed 24/7. The SolGen was able to eliminate this with the inbuild controls and to supply the power to this setup over 52 Days while using 493L of fuel.
