Micro-Inverter Buyer's Guide

With increasing popularity, AC micro-inverters are transforming the world of PV solar power. Their low-cost, module-level optimization and tracking, high-performance and easy installation make them ideal for most residential and small commercial solar systems. In addition to these performance advantages, most micro-inverters have a 25 year warranty to match the long-life of today's PV modules. Inverters are also getting smaller and more adaptable, making for "plug and play" systems that just about anybody can install. This has created more choices for home owners and installers.

Here is a buyer's guide to simplify the selection of micro-inverters for your grid-tied solar project.

about Micro Inverters

A solar micro-inverter, also referred as microinverter or micro inverter, converts direct current (DC) from a single solar panel to alternating current (AC). Micro-inverters are small inverters rated to handle the output of a single panel. The electric power from several micro-inverters is combined and fed into an existing electrical grid. Micro-inverters contrast with conventional string or central inverter devices, which are connected to multiple solar panels.

Micro-inverters have several advantages over conventional central inverters. The main advantage is that, even small amounts of shading, debris or snow lines in any one solar panel, or a panel failure, does not disproportionately reduce the output of an entire array. Each micro-inverter obtains optimum power by performing maximum power point tracking for its connected panel.

Micro-inverters make is easy to assemble complete solar panel systems. Their plug-and-play installation and low voltage operation are ideal for grid-tied PV systems. Plus micro-inverter systems allow for performance monitoring and trouble-shooting at the module-level.
