Advantages:
MUCH SAFER
ACPV Systems are the safest choice for generating solar rooftop power as unlike traditional DC-based string/central inverters which have a high DC voltage of up to 600V running through their DC cables, AC systems are less likely to sustain Arc faults (a major cause of PV fires) due to the internal DC voltage being only that of a single PV module.
FASTER INSTALL
Micro Inverter based systems take up to to 50% less time to install when compared to string based DC systems. As micro inverters are integrated onto the Solar modules and arrive at a job site ready to install, no DC cabling in conduit is required, significantly reducing installation cost and complexity.
MORE DEPENDABLE
The micro inverter is highly reliable as it is designed to operate from -40C to +85C, achieves a peak efficiency of 94.1% and has a 25 year life expectancy to match solar panels. Micro inverters are more dependable through the elimination of the central inverter, which typically requires replacing at least once in a system's lifetime.
MORE PERFORMANCE
Micro inverters allow each solar panel to operate independently and control the power from each with 99.6% accuracy. This results in a significant increase in the performance of the entire system over a single inverter system (see images below). You can also monitor the performance of each AC module online.
24 hours monitoring system:
By connecting micro inverters with NEP communications gateway BDG-256, Customers, distributors and installers could monitor the energy generation at any time and at any place.
