Battery energy storage designed around demand, operating priorities and the way your site actually uses energy.
Understand the solution ↓A Battery Energy Storage System (BESS) stores electricity for use at another time. A complete system combines batteries, power conversion, protection, controls and monitoring. It must be designed around a specific job: using more solar energy on site, managing peaks, shifting energy between tariff periods or supporting selected loads during an outage.
Two ratings matter. Power, expressed in kW, indicates how much load the system can serve at a moment. Energy, expressed in kWh, indicates how much electricity it can store. A battery with enough stored energy may still be unable to start a demanding load if its power capability is insufficient.
Storage does not create extra energy. Conversion losses, usable capacity, reserve settings and ageing affect what is available to the site. A useful assessment therefore starts with measured demand and operating priorities, rather than selecting a battery from a monthly electricity bill alone.
Backup duration and economic viability depend on sizing, tariffs, usage, system design and operating conditions. Battery benefits are not assumed in our preliminary PV calculator.
Commercial and industrial sites, renewable-energy integration and appropriately designed backup or microgrid applications.
Storage can retain surplus daytime generation for later use. The review checks whether there is a regular surplus to charge from, how much evening demand exists and whether the equipment can coordinate safely with the solar system.
For suitable commercial and industrial sites, controlled discharge may help reduce short demand peaks or shift purchased electricity. The opportunity depends on the tariff structure, load profile, charging cost and cycle life.
Backup must be explicitly designed, including isolation from the grid, transfer arrangements and the circuits to be supported. Starting currents, outage duration and required reserve capacity are assessed; a battery connection alone does not guarantee uninterrupted power.
Agree whether the priority is solar self-use, peak management or backup. Where priorities conflict, establish which duty takes precedence.
Use interval demand data where available to assess power, usable energy, charging windows, losses and likely cycling. Review tariffs and replacement assumptions.
Review location, access, ventilation or cooling, fire-safety requirements, protections and control interfaces. Final scope depends on equipment and site-specific engineering.
The final engagement is tailored to your site and agreed requirements.
