Lower your energy costs and keep your site running

A battery energy storage system stores electricity so your site can use it later. Teconnex Power systems combine lithium iron phosphate (LFP) batteries, an inverter and a built-in energy management system in one outdoor cabinet. They store power from the grid, solar, wind or a generator, then release it when it’s most useful to your site.

The system stores energy from the grid, solar, wind or a generator. The energy management system then decides when to use it, based on your site’s demand. If the grid fails, the static transfer switch moves your essential loads onto battery power in 15 milliseconds.

It depends on how your site uses electricity. The case is strongest for sites that generate their own power, such as solar, or that can’t afford a power cut. We look at your consumption data before recommending a system, so any savings estimate is based on your site, not a rule of thumb.

That depends on your daily consumption, how much power you need at peak times, and what you want the battery to do. Our systems range from 25kWh cabinets to 1MWh containerised units, and the modular design means you can add capacity later. Our engineers size the system from a site survey and your usage data.

The cost depends on capacity, power output, installation and grid connection work. Every system is configured for the site, so we provide a tailored quote after reviewing your requirements, with savings shown as a range for your usage.

Yes, for the loads you choose to protect. The static transfer switch moves essential loads onto battery power in 15 milliseconds, fast enough to keep sensitive equipment running. How long it lasts depends on the battery size and how much those loads draw, which we work out during design.

No. The system can charge from the grid, a generator or a wind turbine. Pairing it with solar lets you store surplus generation instead of exporting it, which usually improves the return.

Our systems use lithium iron phosphate (LFP) cells, a chemistry chosen for its thermal stability. Every system comes with multi-level battery management, climate control, and smoke, gas and heat detection with fire suppression as standard. They’re certified to IEC 62619 and UN38.3, and are G99 compliant for grid connection.

Cabinets are IP55-rated for outdoor use and operate from -20°C to +50°C. They’re designed to be moved by pallet truck or forklift. Systems carry a 5-year warranty, with an extension of a further 5 years available on an annual subscription. UK-based engineers support you from survey through commissioning and ongoing maintenance.
