Automatic Load Management
An overview on Automatic Load Management (ALM) and how it works.
Active Load Management (ALM) prevents your electrical supply from being overloaded by dynamically adjusting the charger’s power usage.
It uses CT clamps to monitor your property’s total demand and reduces charging power when required.
How ALM Works
All UK homes have a maximum power rating. Your Hypervolt can be configured to match your property’s fuse limit directly within the device.
ALM continuously monitors the total electrical load in your property. When demand increases (e.g. appliances switching on), the charger will:
-
Reduce charging power
-
Pause charging if necessary
When demand decreases, charging will automatically increase again.
CT Placement
CT1 must be installed on the incoming live tail to accurately measure total property load. The arrow on the clamp must point in the direction of normal current flow to ensure correct readings.
For more information, see CT Setup and Configuration.
CT1 is required under UK wiring regulations to support Automatic Load Management. If it is not installed, or installed incorrectly, charger performance may be affected and the warranty may be invalidated.
FAQs
Q: Will my charger work with solar panels if I don’t have a CT clamp?
CT1 is essential for solar charging; without it, your Hypervolt can’t detect surplus solar energy. If your CT clamp wasn’t installed and you wish to use solar charging, please notify Hypervolt and the installer as soon as possible.
Q: Do I need two CT clamps?
CT2 is only supported by the Hypervolt Home 3.0 or later generations, and only required if you have an AC-coupled ESS.
