Two product lines: module-level safety on the generation side, system-level safety on the storage side

Both product lines share LDSW national-standard communication, in-house SOC silicon and TinyML edge intelligence — for the customer that means one supplier, one interface and one safety record.

HiSRSD · PV module-level safety system

Three layers from field to cloud: shutdown device, controller and platform. Component data flows to the cloud in full, with module-level rapid shutdown, module-level monitoring and AI-driven O&M in one system.

Module-level safety≤25s down to ≤1V

LDSW Smart Shutdown Device

The module-level rapid shutdown actuator for fire, electric shock, maintenance and remote-stop scenarios.

  • String voltage down to ≤1V within 25s, better than NEC 690.12’s 30s→80V
  • MC4 plug-in installation; IP68; 25-year design life
  • Offline autonomy via TinyML edge intelligence

Hisolarmate smart network controller
Control hub≥512 nodes

Smart Network Controller

The on-site control hub with a built-in LDSW gateway module, handling addressing, strategy broadcast, alarm linkage and edge aggregation.

  • ≥512 concurrent nodes per gateway
  • 300m+ effective coverage on complex sites
  • Emergency stop button with fire-interlock testing

Hisolarmate PV safety cloud platform
PlatformAI O&M

PV Safety Cloud Platform

Site overview, module monitoring, root-cause alarm analysis and remote control in one place; large-model assistance moves fault location from days to seconds.

  • Full module records: voltage, current, temperature and conduction state
  • Array heat map with second-level fault location
  • Five AI functions: soiling, hot spot and arc detection

CS-500 · Liquid-nitrogen cryogenic suppression system

A fully automated suppression unit using liquid nitrogen at −196°C, integrating storage, pressurisation, detection and discharge. It interrupts thermal runaway at the earliest stage, before deflagration.

CS-500 liquid-nitrogen suppression system
Storage-side safety−196°C liquid nitrogen

CS-500 Liquid-Nitrogen Suppression System

Oxygen displacement, deep cooling and explosion control acting together to break the thermal runaway chain at source.

  • ~696× expansion ratio; chamber oxygen ≤10% after suppression
  • 500 L liquid nitrogen capacity; 0.01s device response
  • Combined temperature, smoke and gas detection with two-parameter confirmation

How the two lines divide the work

  • HiSRSD handles generation: DC high-voltage shock and string arcing; down to ≤1V within 25s
  • CS-500 handles storage: lithium thermal runaway, flammable gas and in-cabinet deflagration
  • Shared base: LDSW national-standard communication + in-house SOC + TinyML edge intelligence + one O&M entry point

Either line can be purchased alone, or delivered together as a turnkey site package.
