1 MWp solar · 2.4 MWh batteries · 1 MW grid connection · one day in about a minute














Why it matters
At noon, when every solar plant exports at once, a kilowatt-hour costs about €0.035. In the evening it climbs to €0.17 — almost five times more. A battery that only covers your own consumption misses that difference every single day.
A model day, the same one the scene above plays. The real prices of 23 September 2026 are in the next section.
Real market prices
Day-ahead prices on the three markets we work in. The gap between noon and the evening peak is the money a battery earns.

How it works
Inverters, batteries and the grid meter — live, every few seconds, over Modbus or the vendor's API.
Day-ahead and intraday prices, plus the weather forecast for tomorrow's solar production.
When to charge, when to hold, when to sell — within the reserve, cycle and export limits you set.
Sends the setpoints to your inverters and writes down every command with its reason.
See it live
The numbers below follow the same day as the scene above.
What you get
PV, battery, grid and prices for every site, updated every few seconds.
Charge, hold, sell — sent to the inverters on site, within your limits.
Ask why. Get the numbers behind every decision, not a black box.
All sites on one screen: state, current action, revenue, alerts.
Telegram, e-mail or SMS only when a person is needed.
A monthly PDF: revenue, uplift vs. no optimization, cycles used.
Wear cost in every plan. Cycles tracked against the warranty budget.
If the connection drops, the site follows the last plan, then falls back to safe mode.
AI diagnostics
The same data stream that drives the dispatch is checked every few minutes for things that cost you money quietly.
Every finding is logged with the measurements behind it, so you can verify it on site.
Compares every string against its neighbours and the expected value for the irradiance. A string that drifts is flagged before it fails.
Inverter error codes, tripped breakers, lost communication, a stuck relay — with the likely cause and what to check first.
A row producing less than the rows next to it: soiling, shading, a broken module or a loose connector.
Cell imbalance, temperature outliers, capacity fade against the warranty curve.
Telegram or e-mail with the site, the device, the string number and the suggested next step — no dashboard hunting.
Alerts & journal
Faults, string anomalies, price events and the daily result go where you actually read them: Telegram, e-mail or SMS. Everything else lands in the journal, not in your inbox.
Inverter 3, string 7: 612 V — 12 % below its neighbours since 10:40. Insulation resistance 1.8 MΩ, normal — so not a ground fault, most likely a shaded or failed module. Check the connectors on row 2. Lost so far: 4 kWh.
Notes stay with the site and go into the monthly report.
AI assistant
Technology
No new inverters, no new batteries. We connect through whatever your site already offers, and add a small gateway only where local access is missing.
Huawei SDongle and SmartLogger, SolarEdge, SMA Data Manager, Fronius Datamanager — read locally over Modbus TCP.
An industrial mini-PC or Raspberry Pi in the switchboard: polls the devices every few seconds and keeps working offline.
Direct read-out and control of inverters and battery systems: setpoints, limits, modes.
Standard register maps across vendors — one integration for many inverter models.
Victron GX, gateways and meters that publish over MQTT — and the channel we use for cloud sync.
FusionSolar, SolarEdge Monitoring, SEMS, iSolarCloud, Solarman — monitoring where there is no local access.
Janitza, Carlo Gavazzi and the DSO smart meter: the export the market actually pays for.
For sites without wired internet: a managed router with a fallback SIM.
The result
Turnkey
We connect your equipment, set the system up and support it. You pay once — the revenue stays with you.
The app carries your name and colours. Your clients see you, not us.
Runs on your infrastructure or a hosting of your choice. Your data stays with you.
Delivered with the code and documentation. No vendor lock-in.
One price for the project and an optional support plan. Aggregators take a share every month — we don't.
We're ready to develop the system individually for you: we come to your site, inspect the equipment and work out a solution that fits it — not a template.
Next step
We'll show the system live on your equipment and come back with an estimate of what your battery can earn.
