Static vs dynamic load management: what's the difference?
Static shares power to a fixed ceiling; dynamic flexes against the whole site's demand in real time, squeezing out every spare kilowatt.

Not all load management is equal. The distinction between static and dynamic systems decides how much of your connection you can safely use — and it’s worth understanding before you buy.
Static load management
A static system shares power between chargers up to a fixed ceiling that you set — say, a limit that leaves safe headroom below your connection capacity. It’s simple and effective, and it stops the chargers collectively exceeding that ceiling. The trade-off is that the ceiling is conservative: it doesn’t know what the rest of the site is doing, so it leaves a margin unused to be safe.
Dynamic load management
A dynamic system goes further. It measures the whole site’s demand in real time — including lighting, workshops, offices and everything else — and gives the chargers whatever capacity is left under your connection at that moment. When the rest of the site quietens down overnight, the chargers get more; when a workshop fires up, they ease back. It squeezes out every spare kilowatt without ever risking the limit.
Which should you choose?
For a small or simple site, static may be all you need. For any depot where charging is a large share of demand, or where other site loads vary through the day, dynamic pays for itself by letting you charge more on the same connection — often deferring or avoiding a grid upgrade. It’s the difference between designing for the worst case and responding to the actual case.
The practical advice: ask suppliers whether their smart-charging system is truly dynamic and measures total site demand, not just the chargers. On a busy depot, that capability is where the savings live.
