Explanations of energy and electrical engineering, without sales talk
What does kW actually mean? How many kWh suits your home? Here you'll find answers to the questions we get asked every day.
Home batteries
How many kWh of home battery suits my house?
The right capacity depends on your consumption, your solar generation and whether you have a dynamic energy contract. Here's how to reason from usage to capacity.
Read the answerCan a home battery work without solar panels?
Technically, yes. Whether it's worthwhile depends mainly on your energy contract and your usage pattern.
Read the answerWhat happens to a home battery during a power cut?
Not every home battery supplies power during an outage. Back-up functionality requires a suitable system and an adapted installation.
Read the answerCharge points
What is dynamic load balancing?
Load balancing distributes the available power so your grid connection isn't overloaded while charging.
Read the answerDo I need a three-phase connection for a charge point?
On single-phase you typically charge up to around 3.7 kW. If you want to charge faster, a three-phase connection is required.
Read the answerCan I charge my car with solar panels?
Yes, with a charge point that detects surplus from your solar panels and matches its charging power to it.

What is the difference between kW and kWh?
kW is power, kWh is energy. The difference determines what a charge point or home battery can do at any given moment, and for how long.
Read the answerWhat is an EMS (energy management system)?
An EMS coordinates generation, storage, charging and consumption, based on metering data and sometimes on energy prices.
