Usage and features
Energy without compromise
The MyBox AC Sensor for dynamic load management of charging stations optimizes electricity consumption during EV charging. This smart sensor monitors the current consumption of a household or business and automatically adjusts the charging station power to prevent electrical grid overload.
As a result, charging becomes more efficient and safer, because the sensor ensures that the charger uses exactly as much energy as is currently available without limiting other electrical appliances.
Solar management
Maximum solar energy utilization
The MyBox AC Sensor in household and business solar management serves to maximize solar energy utilization. This smart sensor monitors how much energy your solar panels are currently producing and how much other devices are consuming.
Based on this information, it automatically adjusts the charging station power for electric vehicles to efficiently use available solar energy and minimize grid electricity consumption. This helps reduce energy costs and increases energy self-sufficiency.
Cost savings
Saves your wallet
The MyBox AC Sensor helps reduce energy costs: with photovoltaics it charges from the PV surplus, and it always makes sure charging does not overload the main circuit breaker. That often means you do not have to increase the breaker rating, or the regular capacity charges that go with it, and you do not have to limit other appliances.
The result is lower energy bills, bringing long-term financial savings and increasing the energy efficiency of your household or business.

Frequently Asked Questions
01How does AC Sensor measure consumption and adjust charging power?
AC Sensor continuously monitors the total electrical consumption of the building using current transformers. Based on real-time measurements, it calculates the available grid capacity and automatically adjusts the charging station power so that total consumption never exceeds the main circuit breaker limit.
02Where is AC Sensor installed and what is its power supply?
AC Sensor is installed in the building's electrical distribution panel, where it connects to current transformers on the main supply line. The module has compact dimensions of 90 × 65 × 28 mm and is powered by 12 V DC. With IP20 protection rating, it is designed for installation inside the panel at operating temperatures from -25 to 85 °C.
03How many charging stations can be connected to one AC Sensor?
One MyBox AC Sensor can connect and dynamically manage up to 8 charging points simultaneously. This covers the needs of most family homes, smaller apartment buildings, and company parking lots. For installations exceeding 8 charging points, we recommend the MyBox Arm Unit control unit.
04Can AC Sensor be used for solar excess charging?
Yes, AC Sensor supports full solar management. The module measures the total power draw at the main circuit breaker and detects solar energy surplus. When the PV system produces more than the household consumes, AC Sensor automatically directs the excess to the charging station. You can set charging to pure surplus mode, or a combined mode supplementing solar energy with grid electricity.
05How does AC Sensor communicate with the charging station via WiFi?
AC Sensor uses wireless WiFi connectivity standard IEEE 802.11 b/g/n. Once connected to the local network, it communicates with charging stations and the MyBox cloud platform via secure HTTPS and MQTT protocols. The WiFi signal range is sufficient for typical home and business installations.
06Is AC Sensor suitable for a family home with one charging station?
Absolutely. Even with a single charging station, AC Sensor ensures that charging does not overload the house's main circuit breaker – it automatically reduces charging power when you turn on demanding appliances like a heat pump, oven, or dryer. It also enables priority charging from solar surplus if you have photovoltaics.
