⭐⭐⭐⭐⭐ James Wilkins - Homeowner, California
"Installed the SHCET SHQ3-63 Base Model in March 2025 to integrate my rooftop solar array with grid backup. After six months of use, including several grid outages during storm season, the automatic switching between solar and grid has been flawless. The metal housing feels rugged, and I appreciate the manual override knob—gave me peace of mind during a recent inverter fault. Setup was straightforward thanks to the labeled terminals and DIN rail compatibility."Purchase Date: March 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Elena Martinez - Plant Operations Manager, Texas
"We upgraded our backup power system in February 2025 with the Pro Model (250A) for our manufacturing line. The 3-phase 250A capacity handles our heavy machinery without issue, and the 30ms response time has prevented any downtime during generator switchover. The built-in overcurrent protection recently saved a motor control unit during a voltage spike—proving its value. Installation required an electrician, but the DIN rail mounting made panel integration clean and efficient."Purchase Date: February 2025 | Usage Period: 7 months
⭐⭐⭐⭐☆ David Park - IT Infrastructure Specialist, Virginia
"Deployed two SHCET SHQ3-63 Advanced Models (100A) in our co-location facility last November. They’re managing dual-source power for critical server racks. The 40ms switching speed is solid, though not quite as fast as our previous high-speed ATS (5ms), but the UL certification and DIN rail design made compliance and integration easier. Only downside: no remote monitoring, so we had to add external sensors. Still, the manual override and metal build make it reliable for our tier-2 redundancy setup."Purchase Date: November 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Anita Desai - Solar Project Engineer, Arizona
"Used the Base Model (63A) in a remote off-grid home project in January 2025. The dual AC/DC automatic switching works perfectly between solar battery banks and a backup generator. I was impressed by how well the steel housing withstands desert heat and dust—no corrosion after seven months of exposure. The clear labeling and manual knob made commissioning easy, even for the local technician. A durable, no-nonsense ATS that delivers on its promises."Purchase Date: January 2025 | Usage Period: 7 months
⭐⭐⭐⭐⭐ Thomas Reed - Facility Manager, Chicago
"Purchased the Advanced Model (100A) in May 2024 to protect HVAC and emergency lighting in our 12-story office building. After five months of operation—including a city-wide power blip—the switch automatically engaged the generator without a single hiccup. The overcurrent protection kicked in during a lightning surge, isolating the fault and saving downstream breakers. The metal casing feels industrial-grade, and the DIN rail mount saved space in our already crowded panel room. Worth every dollar for the reliability it brings."Purchase Date: May 2024 | Usage Period: 5 months
