Sanhe provide a complete product portfolio from 5kWh residential storage to 30MWh+ containerized systems, serving industrial, commercial, and utility-scale applications worldwide.

Sanhe full-stack approach covers the entire value chain: design, manufacturing, system integration, and cloud-based energy management – ensuring seamless compatibility, higher efficiency, and single-point accountability for our customers.

Power Quality - Harmonic Filtering – we deliver active and passive harmonic filters (APF, AHF, Tuned Filters) that reduce THDi to below 3% and THDv to below 5%, ensuring compliance with IEEE 519 and IEC 61000 standards.

Sanhe provides dynamic reactive power compensation solutions (SVG, capacitor banks, and hybrid systems) that improve power factor to ≥0.95, eliminating utility penalties and reducing energy losses across your facility.

Three-Phase Unbalance Regulator – Unbalance <3%, neutral current elimination, millisecond response, grid code compliance.

Sanhe provides softstarters to protect loads and deliver dynamic voltage restoration solutions (DVR) that protect sensitive equipment from voltage sags, swells, and interruptions, maintaining load-side voltage within ±3% of nominal within milliseconds.
