Grid Tie, Xantrex Technology Grid Tie, From The Sun To Your Utility Meter
OkSolar.com offers two mutually exclusive
types of grid tie inverters systems from
Xantrex:
Grid Tie: A grid tie inverter maximizes power production from a
solar array for running your meter backward. Read more…
Grid Tie with Battery Backup: A grid tie inverter operating with a battery
bank sends power to the grid and provides back-up power during a power
outage. Read more…
Grid Tie
A grid tie inverter changes DC to AC and safely sends your renewable
energy back to the utility company. In this type of system, the utility
grid acts as an infinitely large battery bank storing your generated power
for use by someone else down the line. The following illustration shows
how the typical solar electrical system is configured to send power to the
grid:
Grid Tie with Backup Power (battery based)
Grid tie systems may also include batteries, providing back-up power
during grid outages. A battery-based inverter allows you to send power
back to the utility and protects your home or business against power
outages! The additional cost of a battery based system offers reliable
power during a grid power outage.

This system consists of a solar array and the grid tie inverter. The main
service entrance to the building and the Net kWh Meter are already
installed on existing buildings if utility power is present. A
user-friendly inverter includes all components necessary to make a grid
connect system installation simple and code compliant. The Trace™ ST
Series inverters include the balance of system components for ease of
installation. Read more on the ST Series here.
How it Works
Grid tie inverter systems convert a direct current (DC) energy source
(such as photovoltaic power) into an alternating current (AC). The
inverter sends the power back to the utility grid. In many cases the
electrical generation will be used as it is instantly produced. However,
when the home or business is vacant and energy use is low, the excess
power may be sent (i.e. your energy meter spins "backwards") back to the
utility company and ultimately credits your energy bill. This method of
exchanging power bi-directionally is called net metering and is
increasingly becoming acceptable worldwide. Be sure to contact your
utility company about their co-generation requirements.

This inverter works with larger solar arrays
on the home. It does not have the option to store excess power in
batteries.
- Available in 5, 10, 15 and
20 kW configurations.
The process begins with the sun shining on
solar panels, creating DC electricity which flows to the Trace inverter.
The
inverter processes the power into household electricity and the
electricity goes first into your home to power electric devices. When more
electricity is created than your home can use, the extra electricity flows
to the utility grid (where
allowed, check with your local utility for details), and in essence turns
your electrical meter backward! -- saving you
money. Everybody wins.
