Perific Max with 3x32mm clamp-on current sensors

Perific Max monitors your property’s real-time power draw and dynamically adjusts EV charging output so you never trip the main fuse, even when the car, the kitchen, and the heat pump are all pulling power at once. Instead of requiring a HAN/P1 port on your electricity meter, it clamps onto your existing wiring with three Rogowski coil current sensors — no meter replacement, no cutting power, and installation stays simple even in older buildings.

Beyond load balancing, Perific Max also measures and optimizes solar production, tracks electricity spot prices for cost-aware charging, supports scheduling, and buffers data locally if your connection drops so nothing is lost. It’s built for villas and holiday homes as well as housing associations and commercial properties, regardless of the site’s main fuse size. Manufactured in Sweden and managed through the Perific app, it works with nearly every EV charger brand on the market, with full native integration for Zaptec, Wallbox, and Easee.
