Introduction
Welcome to the growing family of high performance LS600 microinverter system owners. The LeadSolar
Microinverter System is among the most advanced inverter systems for use in utility-interactive photovoltaic
applications. This system is highly reliable, highly efficient, and easy to install. The three key elements of a
LeadSolar Microinverter System include:
• LeadSolar Microinverter
• LeadSolar Link™ Communications Gateway
• LeadSolar Management™ web-based monitoring and analysis software
For most of the PV applications, the LeadSolar microinverter system will benefit the system owner from the
initial system design throughout to the entire lifetime of the system.
2.1 LeadSolar Smart Solar: More Flexibility, More Productivity
Microinverters are what make a distributed solar system possible. Conventional solar grids string numerous
solar panels together and connect them all to a single, central grid-tied inverter. This works well if all panels
are under uniform conditions, but efficiency is lost when some of the panels are shaded by cloud, trees, or
chimneys. Particularly for roof-top residential and commercial PV applications, the output power from a
central inverter architecture is usually not maximized, no matter how advanced PV modules or inverter
technologies are used.

In the LeadSolar microinverter system, PV modules will not be connected to a central inverter. Instead, each
PV module has its own inverter to feed the harvested energy from PV module to electric grid. The maximum
power point tracking (MPPT) controller embedded in the microinverter will monitor the operation of the PV
module in real time and maintain a maximum power point. If one or several PV modules in the system are
shaded, the output power of these modules will drop but the other modules will not be affected and continue to
output at their maximum power level. LeadSolar’s smart solar power system can typically harvest 15% - 25%
more electric energy than a traditional system with one central inverter.
