Qilowatt is a smart energy management platform that automatically optimizes how your home energy system works. We buy and use electricity when it’s cheap, and sell it back when it’s expensive — or participate in the flexibility market – all automatically, 24/7.

Simply put: we make your battery and home energy usage smart and profitable.

– Households with solar panels + battery
– People on spot-price electricity plans
– Those who want to maximize their battery usage
– Homeowners who want to earn passive income from the flexibility market

Qilowatt offers:

✅ Fully automated optimization 24/7
✅ Real-time spot prices, updated every 15 minutes
✅ Flexibility market participation
✅ AI Optimizer – predicts price and consumption ahead of time 

It depends on what you want to do:

OPTION A: Smart control for an existing system
(You already have solar panels + a battery)

You’ll need:
✅ Solar inverter
✅ Home battery
✅ Spot-price electricity contract
✅ Internet connection
✅ Qilowatt device (Shop – Qilowatt)

→ We connect the Qilowatt device to your existing system
→ The software starts optimizing automatically
→ Flexibility market participation becomes available

OPTION B: Starting from scratch / expanding your system
(You don’t yet have solar panels or a battery)

We do NOT sell or install:
❌ Solar panels
❌ Batteries
❌ Inverters

But we can recommend trusted partners:
→ The partner installs the system and connects the Qilowatt device
→ Optimization begins automatically 

Yes! Qilowatt automates inverter and battery management, helping you buy low and sell high.

You can:
– Stop exporting when prices are low
– Charge your battery during cheap hours
– Sell energy when the price peaks

You can also connect your batteries to the flexibility market, earning extra income from grid balancing — completely automatically.Solar panels increase your savings and profit potential, but they are not required. 

– Monthly fee: €3.5 / month *
– One-time device purchase: Shop – Qilowatt 

* The monthly fee of €3.5 applies per control relay.
A control relay = one output channel used for managing devices.
For example, if you use two relays on your Qilowatt device →
your monthly fee is 2 × €3.5 = €7 / month. 

At app.qilowatt.it you can see real-time data, including:
– Total energy consumed
– Average purchase price
– Amount saved during the period
– Income from the flexibility market

Everything is transparent and verifiable — you can see exactly what’s happening. 

No. There are no hidden or additional fees.

You only pay for:
– The monthly subscription, and
– The Qilowatt device itself. 

Based on real user data (example from July):

8 kW inverter + 20 kWh battery → 450 € / per month
10 kW inverter + 30 kWh battery → 570 € / per month
15 kW inverter + 60 kWh battery → 940 € / per month

No, you don’t!

Yes — all settings are open and fully customizable, but you no longer need to configure anything manually.

The Qilowatt Optimizer (AI-based control system) does all the complex decision-making for you. You simply choose your goal — maximize profit or keep more energy for self-use — and Optimizer takes care of the rest. It analyzes market prices, storage levels, and consumption patterns, predicts upcoming price changes, and automatically routes energy in the most efficient way.

Everything works quietly in the background — and you just enjoy the results. 

The flexibility market is one of the key balancing mechanisms of Estonia’s electricity system, through which the system operator Elering keeps grid frequency stable at 50 Hz. By participating in the market, the consumption or production of devices is adjusted in real time to support the grid. Participants receive financial compensation in return.

Both households and businesses can join the flexibility market. When your system is connected via Qilowatt, your battery (or another controllable load) can automatically receive mFRR signals:

– mFRR UP – the grid needs to add energy → the battery discharges to the grid / load decreases.
– mFRR DOWN – the grid needs to remove energy → the battery charges from the grid / load increases.

These signals arise according to the grid situation and usually last up to 15 minutes. After an activation, the device automatically returns to your normal mode, and you can use your battery and other devices fully according to your own preferences — for example:

– charge/switch based on Nord Pool hourly prices,
– prioritize self-consumption,
– keep a reserve for backup power.

The Qilowatt Optimizer handles control automatically within the limits you set, so that your comfort is maintained and earning revenue is as smooth as possible. 

👉🏻 More information about the Flexibility Market can be found here. 

1. Qilowatt registers your battery on the national flexibility market.
2. The grid operator (Elering) sends a signal: “Need more / less power.”
3. Qilowatt forwards this signal to your battery, which reacts automatically.
4. You earn €€€.
