Building on the proven Ecostatic Autosmart platform, the SolarMAX system integrates a high-efficiency solar roof, lithium battery technology, and Victron intelligent power management for continuous, self-sustaining operation.

With the ability to operate for long periods without generator use, the Ecostatic SolarMAX is the ultimate choice for companies committed to cutting fuel use, carbon emissions, and operating costs — without sacrificing performance or comfort.

Built for the Modern Worksite

Like every AJC EasyCabin welfare unit, the SolarMAX system is:

  • Designed and built for long service life
  • Fully compliant with UK and EU welfare and emissions standards
  • Built to order and available for purchase only – we don’t hire, but we can recommend a trusted hire supplier with SolarMAX units in fleet

With Ecostatic SolarMAX, your welfare units deliver next-generation efficiency and comfort — proving that sustainability and practicality can go hand in hand.

Why Choose SolarMAX?

This system delivers ultra-low emissions and exceptional fuel savings, with the ability to run generator-free during summer months due to large solar power input.

System Efficiency Comparison

System Efficiency Comparison

Startup:
Turn system ON. Generator starts/stops automatically when batteries are low.

Lithium Battery system powers ALL SYSTEMS:
Lighting, hydraulics, water pumps, USB sockets.
Hydro Heating powered by diesel tank & battery.
240v sockets, kettle & microwave.

Generator for lithium battery charging ONLY:
When batteries are low the generator is used as a battery charger. Victron systems manage the power flow.

Hydro – Hot water & heating:
Heat & hot water without the generator running.

*Based on 10 hours per day for 260 days, 80 days in winter mode and 180 days in summer mode.
Each day is a typical usage day.
Solar panels achieve maximum output in direct sunlight, but they work in normal daylight and cloudy weather too. The amount of power a solar panel or charging kit generates in cloudy weather will be lower compared to direct sunlight. Also the positioning of the cabin will affect the solar charging of the batteries i.e. under trees, etc.
This assessment doesn’t take in consideration the usage of the hydraulics. This assessment is guidance only.
