What powers true self‑consumption and reliable zero‑export control? High‑quality energy data.

PROJOY PEEM Series smart meters connect PV generation, battery storage, and site consumption — feeding real‑time metrics to inverters and EMS platforms.
🔹 Dual‑channel metering — one meter, two measurement points, simplified wiring🔹 Bidirectional measurement — tracks PV output, grid import & export
🔹 High accuracy — Class 0.5 (V/A/P), Class 1 (energy)
🔹 50 ms refresh rate — stable zero‑export & anti‑backflow control
🔹 Broad connectivity — WiFi + RS485/Modbus‑RTU; optional LoRa, 4G, Sub‑1G
🔹 External CT support — 80A / 120A / 200A, DIN‑rail mounting
🔹 Single & three‑phase — PEEM‑S01 / PEEM‑T01 for residential & C&I

From rooftops to industrial sites, PEEM turns raw kilowatt data into actionable energy management.
