The best price for your energy
Optimise your daily energy profile by selling, buying, using, and holding electricity without keeping an eye on the energymarket.

In the past few years, we've been on a mission to make green energy more cost-effective for its users. Our solution became the TCG-SpotPriceTracker. This fully automated product will help you optimise your energy usage by storing, selling, and buying electricity based on your preferences and current market prices.
History
From tech "nerds" in the 90's and driven by our curiosity about how things work and what we can do to make them even better. With a background in industrial automation and years of experience, we set out to create our own solutions to modern day problems.
TCG-SpotPriceTracker
Optimise your residential energy system and save costs
The TCG-SpotPriceTracker is a price-driven energy management system that automatically lowers your energy costs in many different ways.
1. The Buy/Hold/Consume/Sell profile buys extra energy into the battery when the electricity price is lowest, holds the energy in the battery while the price is still low, consumes the energy from the battery when the price is high and, finally, if the price difference is big enough, sells energy from the battery back to the grid when the price is highest.
2. The EV charge profile charges the electric vehicle when the price is below the set limit.
3. The Relay profile connects loads when the price is low (load adding) and disconnects loads when the price is high (load shedding).
4. All the above can also be triggered based on overproduction from the solar panels to prevent selling your produced energy at low price hours.
5. If the battery is full and the price is negative, the SpotPriceTracker can automatically adjust the solarpower production to only meet the needs of your house and prevent selling.
If you have any questions, don’t hesitate to contact us.
How it works
The SpotPriceTracker gets its energy price data from the cloud and generates a daily control profile for the energy storage system, EV charger and the relay outputs based on the price limits that the user has set in the web-based interface. The SpotPriceTracker continuously communicates with the solar hybrid system and the EV charger to get measurement data and send control commands. Based on price data and measurements, it sets the whole system into the correct operation mode.
Why it works
There are many different factors that have made energy prices fluctuate more and more, and this is likely to continue because of the green transition, electrification and geopolitical instability. Our TCG-SpotPriceTracker raises the self-consumption percentage of solar energy and focuses the selling of energy to high-price hours and the buying of energy to low-price hours.

Green technology elevated
A common misconception is that you need a lot of solar panels to achieve financial gain and a high energy self-sufficiency rate, but that's not true. Too many solar panels usually result in financial losses when selling overproduced electricity while the energy price is low or negative. This also leads to an expensive set-up and a long return on investment time.
When you combine our products with a modern solar hybrid system, including an energy storage system (ESS), you get the most out of your power and renewable electricity without installing too many solar panels – making green technology even greener. Our TCG-SpotPriceTracker also improves your home safety by minimising the risk of overloading the main fuses.

ABOUT US
A young company built on years of experience
Totech was established in 2022 in Forsby, Finland, but our journey began way before that. From childhood friends, we grew into business partners, taking on industrial automation projects on the side of our daytime jobs.
Fast forward 25 years, we came to a turning point where we decided to go all in and create Ab Totech Oy, our very own company, focusing on industrial automation and our own invention, born from a need to make green technology easier, more efficient and accessible for everyone.
Our four guiding principles are accuracy, inventiveness, professionalism, and honesty, allowing us to always put our customer's needs first.
