⭐⭐⭐⭐⭐ James Peterson - Homeowner, Colorado
"Installed the Base Model in March 2025 to integrate with our rooftop solar array. The WiFi connectivity and bi-directional tracking have been flawless—accurately logging both our consumption and surplus energy fed back to the grid. The digital LCD is bright and easy to read, even in direct sunlight. Remote monitoring via the app gives me peace of mind when we're away. After 5 months, not a single glitch."Purchase Date: March 2025 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Lena Park - Operations Manager, SunHarvest Energy
"We deployed 12 Advanced Models across our solar farm in rural Nevada last November. The 4G remote access and 90-day data logging have been game-changers—no more site visits for meter readings. The RS485 integration with inverters is stable, and net metering calculations are precise. CE certification gave us confidence for regulatory compliance. Eight months in, and performance remains rock-solid despite extreme desert temperatures."Purchase Date: November 2024 | Usage Period: 8 months
⭐⭐⭐⭐☆ Daniel Reeves - Site Engineer, Arctic Monitoring Station
"Chose the Pro Model for our remote monitoring station in Alaska due to its -30°C to 70°C tolerance and global 4G roaming. It’s been operational since January 2025 through brutal winter conditions. The IP65-sealed LCD hasn’t fogged or failed, and remote prepaid balance adjustments saved us multiple helicopter trips. Only downside: initial setup required technical support, but once configured, it’s been maintenance-free."Purchase Date: January 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Amina Khalid - Property Management, Texas
"We retrofitted six rental units with the Base Model in February 2025 to introduce prepaid solar billing. Tenants love the transparency—the app shows exactly how much solar energy they’re using versus pulling from the grid. The Class 1 accuracy eliminated billing disputes we had with older analog meters. Setup was straightforward, and the CE certification made city inspectors happy. Four months in, and ROI is already visible."Purchase Date: February 2025 | Usage Period: 4 months
⭐⭐⭐⭐☆ Tomas Gonzalez - Renewable Energy Coordinator, Guatemala
"Working on an off-grid solar project in mountainous regions, we needed reliable remote prepaid meters. The modular 4G/WiFi design allowed us to customize units for areas with spotty connectivity. Installation was smooth, and the bi-directional billing supports future grid-tie expansion. After 7 months, only one unit needed recalibration—far better than expected. A solid solution for developing regions."Purchase Date: June 2024 | Usage Period: 7 months
