Built by a Product Director, not a textbook author.

BESS.courses is built from the chair of a working product engineer in the battery storage industry — not a lecture hall. Every lesson is grounded in projects I have helped deliver.

The instructor

Sergey Syrvachev

I've spent 15+ years in energy and product, including the last 5 in clean energy, building BESS, inverter, and EMS product lines from cell chemistry to grid integration.

I build these courses the way I build products — structured, practical, and grounded in real projects, not theory. The focus is grid-scale BESS: cell chemistry, enclosures, power conversion, controls, fire safety, project finance, and how a battery actually makes money.

If a course helps you make one better project decision, it has done its job.

Everything on this site traces back to a real person working in grid-scale storage. Here's where to check the work and reach me directly.

Where to start

Learn BESS the way it actually gets built.

The complete Grid-Scale BESS course covers the full system end to end — from cell chemistry to grid revenue — and the learning path shows how everything fits together.
