Quiet, and mostly invisible
For LV and HV stackable home batteries. The EMS fills the battery when energy is cheap — from the roof or from the grid at night — powers the house through the expensive hours, and takes over automatically when the grid goes down.
Four jobs, no settings to learn
The household never configures any of this. It is set at installation and monitored remotely by our team.
Self-consumption
Roof generation used in the house first and stored second, instead of being exported for a low tariff.
Cheap-hour charging
Charging from the grid in the cheapest hours so the expensive evening block is covered by the battery.
Automatic backup
When the grid fails the battery takes over. Most families only find out there was an outage when the neighbours mention it.
App and monitoring
The app shows what was saved and when the battery was earning. We watch the system remotely and service it when needed.
One screen, on the phone you already have
The CROSTORION app is live on both iOS and Android. It is the only part of the system a household ever touches — and most weeks they open it out of curiosity rather than need.
- Energy flow, live — generation, consumption, charge and discharge and state of charge, updating as it happens.
- What it has produced — today, this year and cumulative, without digging for it.
- Works with the inverter you have — interfaces for the mainstream brands are built in, so the app is not tied to one manufacturer's ecosystem.
- Nothing to configure — the operating strategy is set at installation and looked after by our team; the app reports, it does not ask questions.
Search CROSTORION on the App Store or Google Play.

The battery earns while it waits
When the house does not need it, the battery can work for the grid through the market layer — helping keep the system stable, and earning while it waits.
Where the rules and the supplier allow it, that is an extra return on a battery the household already owns. At home it stays simple — a smaller bill, month after month.
