Understanding on-site storage

Glossary
BESS, EMS, LFP, OCPP, peak shaving, aggregation. The vocabulary of the trade, in plain language, without needless jargon.
It all starts with a consumption reading. Everything else follows from it.
The house rule
What we do not know, we say so
Throughout this site, every specification shows where it comes from: from the manufacturer's documentation, or from a European distributor's. What is not published is not estimated on the manufacturer's behalf, and no figure is calculated by us from another.
It is more demanding than a site that quotes percentages, and it is the only way to hold up in front of your company's technical director and finance director, who will carry those figures forward.
