1 PREFACE
Load guard is a sensor that is installed in the building’s electric cabinet. It
measures the electric current in the building’s installation and sends real-
time measurements to the charging station.
INCH charging station responds to received data by reducing the charging
power in order to keep the total load of installation below the installation
rated value or increasing it to utilise the remaining available power for
faster charging.
As Load Guard measures electric current in both directions, it is capable
of sensing the power surplus generated by local renewable energy
sources, such as photovoltaics. Green energy is used for faster and
cheaper charging, thanks to algorithms in INCH charging stations.

BENEFITS OF USING LOAD GUARD
• Optimised energy consumption of existing infrastructure.
• Reduced charging and operational costs.
• Local consumption of renewable energy sources.
• Future-proof and grid-friendly charging infrastructure.
