The price of electricity is not fixed: it moves with supply and demand. A smart home battery can respond to that by storing when electricity is cheap and feeding back when the price rises. That is trading on the electricity market, and it happens without you having to do anything for it.
On the electricity grid, supply and demand have to be in balance at every moment. If the wind blows and the sun shines while little is being used, electricity is cheap. If generation drops away at a moment when everyone is using at once, the price climbs.
Without storage you buy when you happen to consume and feed back when the sun happens to shine. With a home battery you store when the price is low and use or sell that power when it is high. Besides saving on your own consumption, that is a second way your battery delivers value.
That does not happen in one place. There are several markets on which electricity is traded, each with its own rhythm and its own purpose. Your battery can only take part if there is software behind it that follows the prices and decides in time.
FlexGrid, the energy management system behind your installation, trades on the day-ahead market, the imbalance market and local energy markets. They differ mainly in how far ahead they look.
On the EPEX Day Ahead market, electricity is traded a day in advance. Tomorrow's prices are therefore known today. So you plan ahead when the battery has to be full, when it may run down and when the car charges. That way you use the price differences and help prevent grid congestion.
The imbalance market keeps supply and demand on the grid in balance at every moment. Being able to take in or give out electricity at the right moment is valuable there. A smart home battery does that: storing when there is too much, feeding back when there is too little.
Besides the national markets, FlexGrid also trades on local energy markets, where supply and demand in the immediate surroundings are brought together. That keeps energy closer to where it is generated and relieves the grid at the points where the pressure is highest.
Trading on the imbalance market asks three things. If one of them is missing, your battery stays a buffer for your own consumption and does not take part in the market.
The prices on the imbalance market move with supply and demand. Only with a dynamic energy contract do those changing rates actually reach you. On a fixed rate you notice nothing of the difference between a cheap and an expensive hour, and the reason to shift falls away.
You need storage to hold power until it is worth more, and software that handles that by itself. The FlexVolt One is built for that: 95% of the capacity is usable and the cells are good for 7,000 cycles, so daily charging and discharging is no exception.
As a private individual you cannot go to market yourself. That takes an aggregator or an energy supplier with the right licence. They bundle the flexibility of many home batteries and offer the whole as one package on the imbalance market.
What trading returns depends on your consumption, your contract and the market prices at that moment. We make no promises about that in advance.
A single home battery is too small for the market to notice. If many are tied together, they behave as one installation that can take in and give out electricity. That is a Virtual Power Plant: not a building with turbines, but software that drives scattered batteries as a whole.
FlexGrid makes that possible. It supports more than 500 communication protocols and uses AI to forecast your consumption, solar yield, charging moments and heat demand. On that basis it decides when charging pays and when feeding back is better. Several installations can work together as one virtual power plant.
You keep sight of what happens. FlexGrid shows in real time what you generate, what you use and what goes in and out of the battery, and warns you by SMS when something goes wrong.
Dysun Energy works with suppliers of dynamic electricity contracts to get the most out of moving prices. Your battery charges automatically when energy is cheap and feeds back when the price rises. You do not have to follow tariffs or switch devices on and off; the control does that for you.
That combines three things that normally stand apart: self-consumption of your own solar energy, flexibility that the market asks for, and the yield that follows from it. A dynamic contract is the key that unlocks all of it.
Taking part in the market touches more than your energy bill. It also changes what your installation means for the grid and for the way electricity is generated.
By responding to price fluctuations you store energy during low prices and feed back at peak moments. That comes on top of what you already save by using your own solar energy yourself instead of feeding it back.
By balancing supply and demand you contribute to preventing overloading of the electricity grid. Exactly at the moments the grid is under pressure, your battery does the opposite of what causes the peak.
Smart energy storage works on its own: the system charges when prices are low and discharges at high prices. You do not have to follow the market or set anything by hand. If you do want to watch along, you see in real time what happens.
Trading on energy markets encourages the use of renewable sources such as solar and wind, because the generated electricity is stored instead of lost during a surplus. That makes it not only financially interesting but also a sustainable choice.
