Why use a Grid Tie System
When a house with solar
power is linked to the utility grid it is called
a grid-tie system. A simple grid tie system allows
the user to subsadise daytime use of electricity
used in appliances like fridges, kettles and lights
using solar power. All power generated by the
solar system is either supplied into the house
or back onto the distributed grid (in case of
excess). Grid tie is a growing an common occurance
in Europe and set to become a world wide norm.
We at Take 2/ Technique offer the best technology
currently available suppled by SMA Germany.

What
does a grid tie system consist of
A basic Grid Tie system consists of a Grid Tie
inverter called Sunny Boys from SMA these connect
directly from solar panels onto the household
AC system. This concept is called AC coupling
and is different in that it does not need battaries.
Without battaries the system is much cheaper and
much more efficient
 
Why
Use SMA Technology
SMA has developed a whole range of complementary
product around their Grid-Tie systems. These include
the options of adding SMA Sunny Island battery
inverters into the system as either backup power
or total offgrid capability. Other capabilities
include wireless transmission of data to GSM networks
or publishing history onto the web.
In addation the Sunny Family
of products allow for endless expandability without
the loss of your initial investment. For example
going from single phase to 3 phase; adding more
power capability; or moving to a hybrid generator
system just means adding more equipment in parallel
with no replacement of sytems.
SMA Grid Tie inverters are installed into the
largest Grid Tie systems in the world some of
several Mega Watts in capacity.
