Solar plant monitoring and automation
Monitoring, automation and energy management. Keep your battery in check, prepare for outages, and control charging and grid export by day-ahead market prices.
Locally on your mini PC or through a separate cloud. Alongside the official app or independently of it.
DEYE today. Other equipment can be integrated on request.
Day-ahead market scenarios are for users with an active consumer contract and energy storage.
Smart automation
You choose what matters most, and the automation adjusts the battery, charging and selling every day to match. It takes your home, the weather, outage schedules and prices into account.
For those who want power at all times.
The home runs on sun and battery; the grid only steps in when your own energy runs out. Nothing is sold to the grid.
For those with a feed-in («green») tariff.
Solar goes to your home and battery first; the surplus is sold to the grid at the feed-in tariff. The battery is never sold — it is your reserve.
For those with an active-consumer contract.
Every day the system makes a plan: charge the battery when energy is cheap, sell when it is expensive. Your outage reserve is never sold.
At first the system only advises. Then it acts with one tap from you. Once you are sure it does the right thing, you can hand it over completely. The goal can be changed at any time.
Independence and the feed-in tariff are part of the «Autopilot» package, the market is part of «RDN». The feed-in tariff and the market need the matching contracts. What is available depends on the equipment; the outage reserve is an estimate, not a guarantee.
Deployment
Choose how you want to work. We check compatibility and available features for your equipment.
Your system. Your data.
The app and its own database run on the plant’s network. Local monitoring and history do not depend on the internet, the manufacturer’s servers or the solar.cordteh.com servers.
Condition. The mini PC needs power and a local connection. New external data, Telegram and remote access require internet.
Reach your plant over the internet.
The plant sends data to a separate cloud server, independent of the manufacturer’s official cloud. You can keep the official app or work without it.
Condition. Requires internet. The provider, hosting country, connection method and storage terms are stated in the proposal.
Keep both running side by side or use solar.cordteh.com independently of the official service. We verify the connection for your specific configuration.
Pricing is agreed once the equipment, deployment and integrations are clear.
Deviation control
The Watchdog analyses the grid, strings, battery and the link to your equipment. It compares output with the typical behaviour of your own plant and notifies you about deviations. In the evening you get a daily summary.
Comparisons depend on history and available weather data. Telegram delivery requires internet.

A string is producing less than its usual range for current conditions. Check its readings and the deviation history.
Demo data
Schedule and forecast
The outage schedule for a supported group, your consumption profile, battery capacity and the solar forecast — in one scenario. The system estimates your energy reserve and helps you prepare the plant for the planned window.
Preparation on your command or through an automatic scenario you enable. For supported schedules you are notified when the schedule is published and 30 minutes before a planned outage.
The generation forecast is tuned on your plant’s history. The forecast horizon takes the estimated autonomy into account.
Estimated reserve for the window
≈ 6 h
Charge at window start ≈ 72% · capacity 30 kWh · average consumption 2.9 kW · solar forecast until 14:00
Clicking changes only this example on the page and sends no commands to any equipment.
The reserve is an estimate, not a guarantee. Emergency outages, schedule changes, weather and consumption affect the result.

ModeSummer
Values are for demonstration and are not a recommendation for your equipment. The demo works only on this page and sends nothing to any equipment.
Battery and modes
Set the lower discharge limit and the upper charge limit right on the battery bar. Switch between summer, winter, reserve and other quick scenarios without hunting for settings.
The buffer ceiling holds the set charge level and keeps spare capacity for the plant to work with variable generation.
Also in the app: immediate charging from the grid, exporting stored energy to the grid and charge current — depending on the equipment.
Scenarios depend on equipment and settings. Software control does not replace the built-in protections of the inverter and BMS.
For active consumers in Ukraine
solar.cordteh.com controls battery charging and grid export by the published prices of the Ukrainian day-ahead market. Your electricity supplier handles the settlements.
Requires an appropriate active consumer contract, energy storage and compatible equipment. Specific scenarios depend on the connection and contract terms.
The day-ahead price is not automatically your net selling price. Financial results are not guaranteed.
Plant plan — example. A planned time does not mean that charging or export has already happened.
Demo scenario. Not a trading signal or an income forecast.
On request, the package can be extended with an integration that submits trade orders to your supplier or aggregator. The exchange format and available operations are agreed before connection.
What the app does
Readings, history and control in one interface. The list of parameters depends on the model, firmware and configuration.
Data for the plant and every inverter: solar per string, home, grid per phase, battery and available BMS readings.
Day, week, month and year, export to a spreadsheet and your own database without a forced 90‑day limit on local history.
Modes, time slots, charge and discharge currents, grid export, time sync and available service parameters according to permissions.
Inverter error and warning codes, system state and a log of important events.
Feed-in tariff calculation with the National Bank of Ukraine exchange rate and configured taxes, net balance, month forecast and report. A calculation is not a received payment.
Add it to your phone’s home screen, share temporary revocable view links and a QR code, and keep a log of changes.
History depth and detail depend on storage. Migrating existing data is agreed separately.
Pricing
The cloud and standard control are free for every connected station. Everything else comes in packages for a monthly fee per station. Prices are stated without a payment method: terms are agreed after your request.

The station tells you when something is off.
Everything in “Cloud” plus:
$6 / month per station
The dashboard prepares the station for outages and does the money.
Everything in “Watcher” plus:
$9 / month per station
Trading on the day-ahead market by a daily plan.
Everything in “Autopilot” plus:
A lower package never erases settings — features are only switched off. Terms for a second and further stations of the same owner are agreed separately.
Remote access is for authorised users. Guests can get a view-only link with an expiry date; you can revoke access and share a QR code.
Changes made through the app are logged with the user and time. Changes made outside the app are marked separately: their author may be unknown.
The system currently works with DEYE equipment. Before connecting, we check the model, firmware, data logger and available features. For other equipment we can develop an integration after a technical assessment.
solar.cordteh.com is an independent product. Manufacturer names indicate compatibility, not an official partnership.
Tell us about the equipment, how you want to work and the features you need.
We check compatibility, the set of components and connection terms.
We demonstrate the agreed scenarios and how to use them.
In the local option, the mini PC receives data and stores history on your network. It needs power and a local connection. Telegram, new forecasts, schedules, exchange rates, day-ahead prices and remote access require internet.
It is the local polling interval for your equipment. The update rate of individual parameters, history recording and data delivery to the cloud may differ.
No. You can keep both running side by side or use solar.cordteh.com independently of the official cloud. The connection method is verified for your equipment.
A separate server is used, not the manufacturer’s official cloud. The hosting country, provider and data access terms are stated in the proposal.
We check this based on the data source you have. In our own installation the cloud history has already been migrated; this does not guarantee import of any format or period.
The system estimates the reserve from consumption history, capacity and the forecast. The actual duration depends on load, weather and outage conditions.
It controls charging and grid export by published prices. Your supplier handles the settlements. It requires an appropriate contract, energy storage and a compatible configuration.
It is a separate package option. Whether integration is possible, the exchange format and the available operations are agreed with your supplier or aggregator.
Yes. On a supported phone you can add the web interface to the home screen. No separate native apps in app stores are claimed here.
Yes. There is a guest view by link with an expiry date, revocation and a QR code. Guest view does not allow controlling the plant.
Pricing is agreed once the equipment, deployment option and required integrations are clear. Send a request to receive a proposal.
