Why choose a home battery?

Save on your energy bill

Our goal is to make energy affordable for everyone and to manage it in a smart way.

Dynamic Energy Rate

Smart batteries can be programmed to store energy when electricity prices are low and use it when prices are high. This allows you to take advantage of cheaper electricity and lower your energy costs without having to do anything yourself.

Trading on the imbalance market

The imbalance market offers opportunities to earn money with your home battery. By making your battery available, you help keep the grid in balance. Grid operators pay a fee for this, which provides you with an additional source of income without requiring any action on your part.

Alpha ESS Smile G3 T10

The ideal home battery for anyone who wants to maximize savings on energy costs and use solar energy wisely. Thanks to smart control, you can take advantage of dynamic energy rates, avoid peak consumption, and even trade on the imbalance market.

10,000 cycles

This corresponds to a service life of 30 years.

1C charging speed

This battery can be fully charged or discharged in 1 hour.

Why choose
smart control?

Always the most affordable energy prices

With smart control, your battery can respond to both the imbalance market and dynamic energy prices, allowing you to get the most out of your energy storage.

Avoid peak consumption and capacity charges

With the capacity rate, your grid fee is determined by your highest peak consumption. A smart battery can smooth out peaks by supplying additional power when your consumption is high.

Synchronize your battery with your smart devices

Do you have an electric car, a heat pump, or an air conditioner? A smart control system ensures that your battery supplies or stores energy at the right time.

Frequently Asked Questions

Can I also use the air conditioner to heat the room?

That's right! Many air conditioning systems are actually air-to-air heat pumps. To heat a space, the outdoor unit extracts heat from the outside air and sends it to the indoor units. Portable air conditioners can only cool.

Is it possible to ventilate using air conditioning?

Some air conditioners can also ventilate your home, but not all of them. At EnergyKing, you’ve definitely come to the right place. Feel free to ask our experts about a model that can also ventilate.

How much energy does an air conditioner use?

The type of air conditioner, the size of the room to be cooled, the capacity of your air conditioner, … These are all factors that affect your air conditioner’s energy consumption. On average, an air conditioner uses 0.5 to 2.5 kWh per hour to cool a room. That’s comparable to a washing machine or oven, depending on the type.

Want to reduce your energy consumption? Then consider connecting your air conditioner to solar panels.

Can I install an air conditioner myself?

You can easily install a portable air conditioner yourself. Are you opting for a permanent system?

In that case, you’ll have to have the installation done by a certified installer anyway. One of the EnergyKing installers, for example 😉
