Decide when your energy moves.

Batteries, with or without PV

A battery is worth exactly what its charge and discharge decisions are worth. Storage is the layer that makes them: it reads the site — production, consumption, meter, state of charge — and controls when the battery charges, when it discharges, and by how much. PV on site is optional. Storage runs on GPweb-Remote, the same controller that already talks to your inverters, your MV protection relay, and third parties like DEDDIE or Fo.S.E.

• Charge and discharge control driven by live site measurement
• Dispatch against tariff periods, load and available production
• Works with or without PV — battery-only sites are a first-class case
• The same controller as the rest of the plant, no second vendor in the system

Your battery, whatever it is

Battery brands turn over faster than inverter brands, and the one you specify this year may not be the one you install next. So the promise is the same one we make on every device in the system: whatever is in your system, if it speaks a documented protocol, we write the driver for it — at no charge. So far, we have not met one we could not do.

The engine behind EMS

EMS is the commercial layer. Storage is the engine underneath it, and we say that plainly because it changes what you buy. The same control that answers "the tariff changes at eight" is the control that answers "hold the battery, we have just been capped." Take EMS and this engine comes with it. Need battery control on its own, with no netting scheme involved? Take it on its own.

Grid commands outrank the battery

In Greece a battery controller does not get the last word, and ours is built that way. GPweb-Remote already resolves competing orders on a plant in a fixed order: the safety cap first, then the grid operator, then the market, then energy management. Battery dispatch enters that order as one more source.

But the system is built to decide the best course of action before something happens. It estimates the risk of a curtailment from the grid operator and keeps that much battery space free for when it comes; it can run several charge/discharge cycles a day, or take an existing energy-sales contract into account.
