HOKO at SNEC: Precision Tech Empowers Smart Energy

From June 3 to 5, the 19th SNEC International Photovoltaic Power Generation and Smart Energy Exhibition concluded successfully in Shanghai. As a holding subsidiary of Liangxin Electric, Guangzhou HOKO Electric made a brilliant appearance under the theme of "Precision Measurement & Intelligent Control, Energy Saving & Carbon Reduction". Co-presenting alongside Liangxin, HOKO showcased the group's end-to-end solutions integrating "low-voltage distribution + metering, measurement, control and protection", and jointly explored new opportunities in PV-storage-charging integration.

During this exhibition, as an important part of Liangxin's new energy ecosystem, HOKO Electric's metering, measurement, control and protection products formed deep scenario complementarity and technical synergy with Liangxin's core low-voltage electrical products. Together, they provide customers with one-stop supporting services from "core switching devices" to "intelligent monitoring and control", further strengthening the group's overall competitiveness in the new energy sector.

Highlights of Star Exhibits

HPM-96 / HPM-120Q Power Quality Analyzers

Adopting 1024-point FFT algorithm and fast half-cycle update technology, these analyzers accurately measure harmonics, interharmonics, flicker and three-phase unbalance, and capture transient load changes in real time, providing reliable monitoring support for PV grid connection.

HKXB-600 Skid-mounted Substation Protection & Control Device

Featuring a four-processor parallel architecture and DSP high-speed processing, it ensures no false tripping and no refusal to trip. It operates stably over a wide temperature range of -40°C to +85°C, supports fault recording and event logging, and is suitable for skid-mounted substation applications in various harsh environments.

HK-4K4P Distributed PV "Four-Function" Device (Observable, Measurable, Controllable, Adjustable)

It integrates AGC/AVC automatic regulation, is compatible with multiple power protocols, and supports WEB configuration. It enables one-stop data acquisition from inverters, weather stations and meters, and realizes inverter data collection and coordinated control. With a fault tolerance mechanism, it ensures more stable operation and safer grid connection.
