Introduction

Configuring the energy profile in the Qilowatt app ensures that your system correctly calculates energy purchase, sales, and network costs. This allows the Optimizer to make accurate decisions based on your specific electricity contracts and tax setup.

Prerequisites

• Qilowatt account created → Creating a user account
• Device connected to WiFi → Connecting a device to WiFi
• Inverter added to the Qilowatt app → Module setup
• Solar plant and battery data correctly configured → Solar inverter setup

Step-by-step Guide

1. Open device information

• Log in to the Qilowatt app and from the left menu, under Dashboard or My Devices choose the programmable device (e.g., Qilowatt Modbus R2).

• On the device page, locate the Device Info section and click Edit

2. Energy profile

The Energy Profile displays the final import and export prices (buy and sell prices) as well as all price components separately. The price is calculated automatically based on the selected parameters.

For example, when selecting a fixed electricity price where daytime and nighttime prices differ, the system automatically calculates the correct price, also taking into account weekends and public holidays. Public holiday dates are displayed in the network fees section.

By clicking on the Export value, the export price components will be displayed.

By clicking on the Export value, the export price components will be displayed.

3. General settings

Price Unit
Choose how energy costs and production are displayed.
• €/MWh – euros per megawatt-hour
• €/kWh – euros per kilowatt-hour
• c/kWh – cents per kilowatt-hour

I receive renewable energy support (5.37 c/kWh)Enable this option if you receive renewable energy support. In this case, the support payment is added to the export price when the spot market price is above zero.

Include VAT (24%)
• Enable if you are a private consumer.
• Disable if you are a VAT-registered company.

Note! Margins must be entered into the energy profile without VAT. The system will calculate VAT automatically.

4. Margin settings

Disable if you are a VAT-registered company.
Select the option according to the contract you have with your electricity supplier.
• Spot + margin – if the contract is linked to the spot market price with an added fixed margin.
• Spot + percentage margin – if the contract is linked to the spot market price with an added percentage margin.
•Fixed price package – if the contract has a fixed price. Select the tariff type depending on whether the contract has the same price for the entire day or different prices for daytime and nighttime.

Export Margin (Selling to the grid)
Select the option according to the contract you have with your electricity supplier.
• Spot + margin if the contract is linked to the spot price with an added fixed margin. Enter this value as negative (with a minus sign).
• Spot + percentage margin – if the contract is linked to the spot price with an added percentage margin. Enter this value as positive.
• Fixed price package – if the contract has a fixed price. Select the tariff type depending on whether the price is the same throughout the day or differs between day and night. Enter this value as positive.

Note! Export and import margins are different. Make sure you enter the margins for selling electricity back to the grid here.

4. Network fees configuration

Provider
Select the grid operator whose service you use.

Plan
Select the network tariff package you are using.
Note! If you cannot find a suitable option in the list, please contact us.

Once all information has been entered, click the “Save” button.

Result

Your energy profile is now configured. Qilowatt uses these parameters to calculate energy costs, revenues, and optimize energy flows in real time.

If it Doesn’t Work

• If the system does not respond as expected, check the margin values.
• If sales happen at a loss, ensure that the sales margin is entered as a negative value.
• If the problem persists, contact the Qilowatt support team: support@qilowatt.eu

• Currency precision: Information can be displayed in €/kWh or c/kWh.
• Click Next.

3. Vendor and model

• Vali elektriseadme tootja ja mudel.
• Klõpsa Next.

if you choosed Solar Inverter with Batteries you will be continuing with Plant setup.

4. Plant setup

• Enter the address and drag the GPS pin to the exact location where the solar panels are installed.
• Click Next.

5. Inverter

• Inverter max power – maximum power in device operation mode.
• Main breaker size – according to the electrical connection box.
• Max export limit – according to the contract with the grid operator (e.g., for nano-producer 790 W, if no contract → 0).
• Click Next.

6. Plane

• Click + Add group.

• Installed power – plant’s total power in W.
• Angle – tilt of the panels relative to the ground in degrees
• Azimuth – orientation relative to compass direction in degrees. For easier azimuth setup click Go to SunCalc
• On the SunCalc page, you will see the address you entered earlier in step 4. Solar plant. Make sure the GPS pin is centered on the panels.
• At the top row of the browser window, you will see a time range 00:00–23:00

• Move the cursor along the timeline until the yellow line is perpendicular to the panels, as shown in the photo.
• On the left panel, the table will display your panel’s azimuth.

Cascade Solutions

Qilowatt Support — Wed, 17 Sep 2025 09:06:48 +0000

Introduction

For cascade solutions, where inverters are connected in a Master–Slave configuration, settings must be adjusted depending on what data Qilowatt reads and whether the system is connected only to the Master inverter or also to the Slave inverters.
Below is an example of Deye inverter settings. Other manufacturers may have small differences that require testing.

Prerequisites

• Qilowatt account created → Create user account
• Inverters added to Qilowatt app → Module setup
• Inverters connected in Master–Slave configuration according to manufacturer’s manual

Master–Slave settings

Settings	Qilowatt is connected to only Master	Qilowatt is connected to Master and all Slaves
Inverter Max Power	Master max power	Total power of plant
Max Export Limit	Export Limit per inverter	Total Export limit of plant
Peak Shaving	Import limit per inverter	Import limit per inverter
Battery Capacity	Battery capacity per inverter	Battery capacity of plant
Battery Max Charge Current	Charge current per inverter	Charge current per inverter
Battery Max Discharge Current	Discharge current per inverter	Discharge current per inverter

Result

Inverters operate in a Master–Slave configuration. Qilowatt applies the settings depending on whether it is connected only to the Master or to both the Master and all Slave inverters.

If it Doesn’t Work

• Check that all inverters are properly connected in Master–Slave mode.
• Make sure inverter firmware is updated.
• If the problem persists, contact the Qilowatt support team: support@qilowatt.eu
