Using PV Forecast

Qilowatt Support — Tue, 13 Jan 2026 09:12:04 +0000

Introduction

A new setting called “Use PV forecast” has been added under the Qilowatt Optimizer.
This setting allows you to decide whether the Optimizer should take solar production forecasts into account when making its calculations.
While this option is very useful in normal conditions, it requires special attention during the winter period.

Why is this setting important?

When Use PV forecast is enabled, the Optimizer includes solar energy production forecasts in its decision-making process.

During winter, situations may occur where:
• solar panels are covered with snow,
• panels are not cleaned regularly,
• actual production is significantly lower than the forecast.
In these cases, the forecast may not match reality and can negatively affect the Optimizer’s performance.

If your solar panels are covered with snow during winter or are not cleaned regularly, we recommend disabling the PV forecast.
See muudab Optimizeri töö täpsemaks, stabiilsemaks ja Teie jaoks kasulikumaks.

Step-by-step Guide

How to find and change the PV forecast setting
1. Open Qilowatt App.
2. From the left-hand menu, select “Addons” and klick “Optimizer”.
The Optimizer view will open:

3. Find the section “Solar panels”.

4. Enable or disable Use PV forecast as needed.
5. Klick “Save”.

Result

After saving, the Optimizer will:
• use solar production forecasts when the setting is enabled, or
• rely only on actual measured data when the setting is disabled.
Disabling the PV forecast during winter helps avoid inaccurate decisions and ensures reliable Optimizer performance.

Flexibility Market – Report Information

Qilowatt Support — Tue, 02 Dec 2025 09:01:00 +0000

Introduction

Flexibility market revenue can be viewed in detail using the report Balancing Service Revenue Details. Below is an explanation of all fields shown in the report and what they mean.

Field Descriptions

Trader
– Flexibility market service provider, in this example KratTrade.
Start
– Start time of the regulation signal.
End
– End time of the regulation signal.
BRP Compensation
– Compensation (BRP Comp) used to cover the balance provider’s cost caused by the customer participating in the flexibility market.
👉 Detailed explanation in the section What is BRP Compensation?
UP Regulated Energy
– Measured energy volume during upward regulation (selling direction).
Only the change is counted:
A baseline value (zero point) is calculated 4 minutes before the signal starts, and the payable energy is measured from this baseline.
UP Revenue
– Total revenue from upward regulation (selling direction).
UP Revenue – BRP
– BRP Compensation deducted from upward regulation revenue (paid to the balance provider).
DOWN Regulated Energy
– Measured energy volume during downward regulation (buying direction).
Only the change is counted from the baseline determined 4 minutes before the signal.
DOWN Revenue
– Total revenue from downward regulation.
DOWN Revenue + BRP
– BRP Compensation added to downward regulation revenue (paid to the customer).
During DOWN signals the customer consumes more or produces less, which stabilises the system and reduces the BRP’s balancing cost.
For this reason, BRP Comp is positive for DOWN direction.
Total Regulated Energy
– Total volume of regulated energy.
Total Revenue
– Total revenue.
Total Revenue BRP
– Total revenue including BRP Compensation.
Revenue %
– Customer’s contractual revenue percentage.
Total Revenue Share
– Customer’s share of the total earned revenue.

What is BRP Compensation?

Every electricity supplier (e.g., Alexela, Enefit, etc.) must forecast daily how much electricity their customers will consume or produce the following day. Based on this forecast, electricity is bought or sold on the Nord Pool market.

When a customer participates in the Flexibility Market, their battery or other device follows Elering’s frequency regulation signal, meaning it consumes or produces exactly what the system requires — not what the balance provider predicted.

This creates a deviation from the forecast, called imbalance energy. The balance provider must later buy or sell this energy on the balancing market. Balancing market prices differ from Nord Pool prices and can be more expensive for the balance provider.

To ensure the balance provider does not incur losses because the customer participates in the flexibility market, BRP Compensation is used: it is a small portion of the customer’s flexibility market revenue that is automatically redirected to the balance provider to cover imbalance costs.

This is fully automatic for the customer — KratTrade handles BRP Compensation payments directly to the balance provider. The customer receives the rest of the flexibility market revenue.

Solis S6

Qilowatt Support — Thu, 18 Sep 2025 11:54:07 +0000

Introduction

Solis S6 inverters can be connected to the Qilowatt system via Modbus communication. This guide explains the necessary preparations, RS485 wiring, inverter settings, and operating modes.

Prerequisites

• Inverter and battery firmware are updated (latest version must be used)
• A Modbus module is available
• Required tools and a communication cable (CAT5 or CAT6)
• A Qilowatt account has been created and the app is ready for adding devices → Creating a user account

Step-by-step Guide

1. Preparation

• Update the inverter and battery firmware before connecting.
• Ensure the device has the latest firmware, since Qilowatt always relies on the newest Modbus protocol.

2. RS485 connections

↓ Solis S6 3-10kW HV; Solis S6 8-15kW LV ↓

↓ Solis S6 12-20kW HV ↓

Solis S6 30-125 kW tuleb ühendada EMS porti, mitte RS485. (Juhul kui akuks on Dyness BF100, tuleb Qilowatti kontroller ühendada EMS porti, Aku BMS kaabel BMS porti ja aku EMS kaabel RS485 porti.)

3. Inverter firmware and SolisCloud settings

It is critical to update the inverter firmware after installation.
All firware components must be updated: DSP firmware, HMI firmware, Major firmware and all other inverter firmware components.

All SolisCloud control functions must be turned OFF.
If any of the following functions are enabled in SolisCloud, it is not possible to control the inverter.

1) Solis AI, Peak Valley Arbitrage, Solis EMS and other automatic control functions must be turned OFF.

2) Storage Mode → Charge & Discharge time slots must be turned OFF.

3) We recommend turning OFF Battery Saving, located under Battery Settings. This setting limits battery usage and reduces charging and discharging power.

4) We recommend turning OFF Battery ECO Function, located under Settings -> Function Settings. With some battery systems, it is not possible to charge the battery when it is empty and no PV production is available.

Result

Solis S6 inverter is successfully configured and connected to the Qilowatt system. The module transmits data and enables inverter control and energy optimization.

If it Doesn’t Work

• If communication does not work, check the RS485 connections
• If the issue persists, contact our team: support@qilowatt.eu

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

Custom Control Logic Adjustable Parameters

Qilowatt Support — Wed, 17 Sep 2025 07:46:13 +0000

Introduction

The Custom control logic allows users to modify detailed parameters that directly influence how the inverter and battery operate. This provides flexibility but also requires a solid understanding of how the system works. Incorrect configuration may reduce profitability or cause unexpected behavior.

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 inverter configured → Solar Inverter Setup
• Control logic set to Custom → Control Logics

Step-by-step Guide

1. Charging and discharging losses

• Low-voltage batteries (<100 V): typically 14–20% loss per cycle.
• High-voltage batteries: typically 8–14% loss per cycle.
• Adjust values according to your battery’s voltage. The higher the voltage, the lower the current → less heat and lower losses.

2. Charging and discharging degradation cost

• Every kWh charged into or discharged from the battery shortens its lifespan.
• Manufacturers usually guarantee a lifetime of ~6000 cycles. Based on battery cost, capacity, and expected cycles, you can calculate LCOS (Levelized Cost of Storage), which shows the cost per kWh of using the battery.
• LCOS should be split equally between charging and discharging degradation costs.

3. Minimum state of charge for selling (Sell Min SOC)

• Defines how much energy must remain in the battery after a sell command finishes.
• Example: if Min SOC = 15% and Sell Min SOC = 20%, then 5% remains in the battery after selling.
• Each percent left unsold reduces profitability but may be useful in specific cases.

4. Minimum state of charge for PV Sell (PV Sell Min SOC)

• Defines the minimum SOC required before PV Sell mode can activate.
• PV Sell starts in the morning when PV forecast ≥ historical average consumption.
• For fluctuating loads, it’s wise to store some energy in the battery before PV Sell to avoid covering consumption from the grid.

⚠️ Recommended: 2–5% higher than Min SOC. If set too high, expensive morning energy will be stored in the battery, reducing profitability.

5. Enable PV Sell

• Should be disabled if the inverter has no PV input or for specific models (e.g., Deye, Sungrow) where the export limit is more than 2× lower than the total PV capacity.
• If PV input and export work normally, keep this enabled.

6. Planned battery state of charge (end of period)

• The “end of period” = the last hour for which day-ahead market prices are available.
• This setting controls the target battery SOC at the end of that period.
• Recommendation: set around 60% SOC.

7. Buy price

• Minimum extra revenue required for charging the battery.
• Not recommended — no practical use case has been identified.

8. Sell price

• Minimum extra revenue required when discharging from the battery.
• Example: if set to 0.10 €, the system will only sell if it earns 10 cents per kWh in addition to covering losses and degradation costs.

Result

The Custom control logic enables detailed fine-tuning of inverter and battery behavior. With correct settings, the system can be adapted to very specific use cases. However, incorrect values may lead to lower profitability.

If it Doesn’t Work

• If the system does not behave as expected, review all parameters carefully and compare with your battery manufacturer’s specifications.
• If the outcome is unsatisfactory, restore default logic → Maximum Profit or Self-consumption.

⚠️ Qilowatt support does not provide assistance with Custom settings or troubleshooting. Responsibility for Custom configuration lies entirely with the user.

Control logics

Qilowatt Support — Wed, 17 Sep 2025 06:49:04 +0000

Introduction

The Optimizer uses different control logics to decide how to manage the battery and solar energy usage. Choosing the right logic directly impacts profitability and energy efficiency.

Prerequisites

Step-by-step Guide

1. Maximum Profit

• Purpose: use the battery primarily for generating revenue.
• The system automatically finds the best times to charge and discharge the battery.
• Higher-value solar energy is sold directly to the grid.
• Only the required amount of energy is stored for later sales or self-consumption.

2. Self-consumption

• PV production is stored in the battery exclusively for local use.
• Energy is only sold from the battery to the grid when prices are very high.
• If the user has no agreement to sell energy to the grid, this logic must be used.

3. Custom

• Allows manual adjustment of parameters and control logic.
• Before making changes, we recommend clarifying how a particular parameter affects the system → Custom Control Logic Adjustable Parameters
• A working configuration can always be restored by selecting Maximum Profit or Self-consumption.

⚠️ The user takes full responsibility for incorrect settings when using Custom. Qilowatt support does not provide recommendations for parameter values and will not troubleshoot issues caused by Custom settings.

4. Note

While Self-consumption logic is available, we recommend using Maximum Profit. Battery technology is becoming cheaper every year, and in about 10 years, current batteries will be obsolete. New batteries will cost the same (or less) but have 2–3 times higher capacity.

Result

By choosing the correct control logic, Qilowatt Optimizer will manage your inverter and battery in the most efficient way to match your goals.

If it Doesn’t Work

• If the inverter does not behave as expected, ensure that Maximum Profit or Self-consumption is selected.
• If you changed parameters in Custom mode, try restoring the default settings.
• If the issue persists, contact our team: support@qilowatt.eu
