Optimized Energy Management: Utilizing time-of-use and demand charge structures, these inverters minimize grid reliance and reduce electricity bills. UPS Functionality: Fast switching (<10ms) ensures continuous power to critical loads, with up to 150% peak output in backup mode. Enhanced Safety: Built-in AFCI and rapid shutdown provide superior system protection.
Inductor external:Temperature inside of the box is effectively reduced by isolating the main heat source,which significantly improves the reliability and lifetime of inverter. All aluminum chassis design:Light and compact with premium whole body cooling. Surface treated by anodic oxidation, which enhances high strength, effective antioxidation and corrosion resistance from acid and alkali. External WIFI/485/GPRS option:Enable customers to get to know inverter operation status easily. Touch button:High reliability and more responsive.
