Load balancing in three levels
We call our load balancing for NANOGRID™. It’s a smart power solution for overload protection over the power grid. With our system, you do not have to worry about getting the main fuse tripping. We have three different types of load balancing depending on your needs.
NANOGRID™
CTEK Grid Central (CGC)
With our external CTEK Grid Central cabinet, the load balancing system can also take other important consumers into account such as lifts, ventilation, lighting, etc. The system keeps track of other consumers via transformer measurement. Our Grid Central is a compact device cabinet that contains a charge control unit, energy meter and transformer measurement equipment.
NANOGRID™
Local
Our local load balancing is managed directly from the charge control unit into a selected “master device”. All devices are connected with ethernet cables to a common switch. The load balancing can then be set as desired and against a given value or main fuse. Our local load balancing works without an internet connection.
NANOGRID™
Home
With our popular load balancing for home use, you never have to worry about the main fuse tripping. An additional energy meter is mounted at the incoming mains, which then “talks” via modbus communication to the wallbox. We set the main fuse data into our charge control unit, the charging is then dynamically adjusted and the house always has priority.
Load Balancing Products
Load balancing with external device cabinet, NANOGRID™ – CTEK GRID CENTRAL (CGC)
CTEK GRID CENTRAL is a long-term investment that enables reliable and carefree electric car charging. CTEK GRID CENTRAL is a separate device that contains all load balancing technologies. This box manages charging stations and also external loads such as lighting, ventilation, elevator and more. With our unique load balancing system, important electrical equipment in the parking environment can be prioritized and the power grid is protected from overload. When several electric cars are charging simultaneously, overload in the mains can occur. In some cases, the fuses will trip. With CTEK GRID CENTRAL, a costly redevelopment of existing power grids is avoided.
The system measures the service that enters the property and controls the power outlets in the charging stations. The size of the main fuse is fed against the grid control board. This is all our system needs to ensure the stability of the property network.To install charging stations as well as CTEK GRID CENTRAL, a qualified and trained electrician is required.
NANOGRID™ – CTEK GRID CENTRAL, perfect for:
Parking lot, shopping centres, real estate, industries, etc.
“We have increased the number of EV charging points every year. Mainly due to the increase in the number of electric cars, but also we always try to be one step ahead, to meet future demand. CTEK was selected because we felt they could deliver a solid and reliable charging solution, with high technological performance standards.”
- Karl-Johan Wall, Hufvudstaden, NK parking, Stockholm
Load balancing – between several devices, NANOGRID™ – Local
When several electric cars charge at the same time, load balancing can be required to avoid overload. In case of overload, the system automatically adjusts the power of the charging stations or alternatively turns off them completely. With load balancing enabled, the electric car charge will be limited to the maximum allowable current. If the power is controlled, charging will take a little longer, but no fuse will trip.
The load balancing function is based on Ethernet communication between the wallboxes. To each device, power and Ethernet cable is connected at the time of installation. The stations are connected in a common switch. The system does not need to be connected to the internet to work, local communication between the devices is sufficient for full functionality.
NANOGRID™ – Local, perfect for:
Tenant, company, parking etc.
"Stockholm Parkering has confirmed that all new developments will install EV charge points in 100 percent of the total parking spaces, with the remaining parking spaces being ‘EV ready’. The CTEK solution is fully scalable, enabling Stockholm Parkering to lay down the foundations for further growth and expansion over time."

Load balancing at home, NANOGRID™ – Home
With our load balancing for your home to CHARGESTORM CONNECTED, you not have to worry that the main fuse will trip. The power of the charger will automatically be set at no risk for overload. With CHARGESTORM CONNECTED, you can make an option with a load balancing feature at home. The solution means that an additional energy meter is mounted on incoming feed. This energy meter is wired to the charging station’s control board.
When the load balancing is activated, it automatically works and the car’s charge is adjusted and optimized all the time, depending on how much power the house draws. Our load balancing solution protects your home’s power grid from overload while providing efficient charging.
NANOGRID™ – Home, perfect for:
Villa, summerhouse, guesthouse etc.
“The first EV charging products we always talk about are CTEK products. And that is because when we recommend CTEK, we know we are delivering our customers technology that they can have confidence in. They have great products and deliver excellent technical support.”

How load balancing works
Electric car load balancing is a vital component of the new infrastructure. It allows charging stations to share available power supply among charging cars, ensuring charge even when the charging station has limited available power supply.
Load balancing provides smart charging, which sets and regulates charging management across charging stations to maximize efficiency while avoiding overload or increasing power supply costs. It guarantees that an electric car in a family, restaurant, or company fleet is prepared for each day's problems in the same way that traditional gasoline and diesel-powered vehicles are.
CTEK’s NANOGRID, an advanced load balancing solution
NANOGRID-Load Balancing system is one of the many great innovations provided by CTEK. Its function is the smart power distribution from a cluster of electric vehicle charging points when they are being accessed by not only one but several electric vehicles, intending to ensure the total incoming supply capacity is not exceeded.
When used in a cluster, CTEK's NANOGRID provides scalable load balancing to guarantee that the incoming electrical supply is not overburdened due to excessive charger use. No matter if it is at your home, office, or commercial property, NANOGRID provides you smart overload protection with adjusted and optimized power availability. To provide efficient charging, NANOGRID comes in three different modules, to make efficient your home, office, and commercial EV charging requirements.
Unique architechture
NANOGRID's architecture is unique in that it automatically analyses available capacity and determines how much power a vehicle requires. Following the completion of the analysis, the charging units will distribute electricity based on the maximum capacity of the connection. Electric cars may always be charged using this technology, even if the installation has limited capacity.
The load balancing method is based on the wall boxes communicating over Ethernet. When the system is set up, each device is given power and an Ethernet cable. A shared switch connects the stations. The system does not need to be linked to the internet to function because local communication between the devices is sufficient.
The system monitors and manages the power outlets in the charging stations as well as the grid that enters the property. The primary fuse size is fed into the grid control board. This is all our system needs to assure electricity stability throughout the property network.
