Solatainer Off-grid Power Generator
Overview
The Prolectric Solatainer® provides dependable, solar-generated electricity that can be used as the primary source of off-grid power on site compounds in the construction, rail and infrastructure sectors.
The Solatainer is a stand-alone generator that achieves a huge reduction in diesel usage compared to conventional generators. Fuel and manpower costs are therefore dramatically reduced, normal running is silent, and emissions are minimal.
A standard Solatainer can be used as a direct replacement for a diesel generator for power demands up to 25 kW. The Solatainer is also scalable up to 100 kW, by increasing the size of the photovoltaic array and the battery capacity.
Modelled on a standard 20ft shipping container, the Solatainer’s array of photovoltaic (PV) solar panels harvests energy during the day to charge on-board lithium ion or deep-cycle lead acid battery storage.
A standard Solatainer comprises of a 4kWp PV array, 15 kWh battery pack and a 15kVA or 25 kVA stand-by generator, however every Solartainer can be configured to meet the power needs of your site.
Available for hire or cross-hire, the Solatainer is the UK's first autonomous solar-powered off-grid generator with a proven track record in hundreds of projects sites in the rail and construction sectors nationwide.

Reliable, Renewable Power
The Solatainer is the UK's first autonomous solar-powered off-grid generator with a proven track record in hundreds of projects sites in the rail and construction sectors nationwide.
Diesel Savings
Fuel usage is typically reduced by 80% compared to a conventional diesel generator.
Configurable
A standard Solatainer can be used as a direct replacement for a diesel generator for power demands up to 25 kW. The Solatainer is also scalable up to 100 kW.
Complete Energy Security
The Solatainer’s automated system is programmed to demand power from the standby diesel generator when the batteries are depleted below a set limit, or to respond to a spike in demand.
Remote Control and Monitoring
Each Solatainer is equipped with a micro-controller and GPS tracking, so it can be switched on and off remotely, and key data such as power generated/consumed can be monitored and recorded. You can change the settings without attending on site – or we can do it for you.
Regular reports can be provided to track performance and carbon saved compared to conventional alternatives.
Electrical Certification
The Solatainer is delivered fully-charged and set up for you on site with a full distribution board by the Prolectric team. Our fully-qualified electricians hand over a certified system to you that’s immediately ready to operate.
