Terms and conditions of the Gridzilla service
Valid from 30 October 2026
1. Provider
Tekvica, s. r. o., Blatnica 492, 038 15 Blatnica, Slovakia. Company ID (IČO) 52 765 024, tax ID (DIČ) 2121155047, VAT ID SK2121155047. Registered in the Commercial Register of the District Court Žilina, section Sro, insert no. 73541/L. Brand VictronLab.
Contact: info@tekvica.com. We answer questions within two working days.
2. What we provide
Gridzilla is a service that plans and controls your battery, your solar system and, depending on the plan you choose, your heat pump, hot water, heating and EV charging by your tariff and the weather forecast. Remote setup, the overview, updates and support are included.
Gridzilla changes device settings only within the limits you set. You can switch any device to watch-only. If Gridzilla stops sending commands, the device returns to your settings (with Victron within 3 minutes).
You need compatible devices (for example a Victron Cerbo GX) and an internet connection. Before you order we check that your system is supported.
3. Conclusion of the contract
In reply to your enquiry we send you an offer by e-mail. The contract is concluded when you accept the offer and we confirm the order by e-mail. We attach these terms to the confirmation so that you have them on a durable medium.
4. Price and payment
The Home plan costs 3.90 € a month and the Large home plan 9.90 € a month, including VAT (currently 23 % Slovak VAT). There is no setup fee.
You pay the first 12 months (the minimum term) up front in one payment: 46.80 € for the Home plan, 118.80 € for the Large home plan. After that the subscription is paid monthly in advance.
A mini PC or custom work is charged separately according to the offer, and only if you order it.
5. Term and cancellation
The contract is concluded for 12 months. If you do not cancel it, it continues automatically for an indefinite period.
After the first 12 months you can cancel the subscription at any time, effective at the end of the calendar month in which we receive your cancellation. The Cancel subscription form on this website or an e-mail is enough.
One month before the end of the first 12 months we send you a reminder.
We may terminate the contract with one month's notice; we refund any subscription paid for the period after the end.
6. Savings guarantee
Every day Gridzilla compares your actual electricity costs with a calculation of what you would have paid with a normally configured battery (self-consumption without planning) under the same conditions. You see the sum of these daily savings in the overview.
If the savings in the first 12 months are lower than the amount you paid for them, we refund the difference within 30 days of the end of that period.
The guarantee applies if control was switched on and the devices were connected at least 90 % of the time, and if you told us about any change of tariff.
7. Withdrawal from the contract
You may withdraw from a contract concluded at a distance without giving a reason within 14 days of its conclusion. An unambiguous statement is enough, for example the model form below or an e-mail.
If you want us to start the setup before the 14 days have passed, we ask for your express consent and your confirmation that you have been informed: once the service has been provided in full, the right of withdrawal ends. If you withdraw after the service has started, you pay only a proportionate part of the price for the services provided up to the day of withdrawal.
We refund all payments within 14 days of receiving your withdrawal, by the same means you used to pay.
8. Your obligations
Provide access to the devices and an internet connection, and do not change the safety settings we agreed on without letting us know. Tell us about any change of tariff, devices or the way you use the house, so that the plan matches reality.
9. Defects and complaints
We are liable for defects in the service under the Slovak Civil Code. Send complaints by e-mail or through the form; we deal with them without undue delay and within 30 days at the latest.
If you are not satisfied with how a complaint was handled, you may ask us to put it right and then apply for alternative dispute resolution to the Slovak Trade Inspection (www.soi.sk) or another body on the list of the Slovak Ministry of Economy.
10. Personal data and final provisions
We process data according to the privacy policy published on this website. To provide the service we need the electricity production and consumption data of your devices.
We notify you of changes to these terms by e-mail at least one month in advance; if you do not agree, you may cancel the subscription free of charge as of the day they take effect. The contract is governed by the law of the Slovak Republic; mandatory consumer-protection rules of your country of residence remain unaffected.
