Built by a Director of Product Engineering, 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 worked in energy and product since 2010, and in battery energy storage since 2020, 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.
