Your Solar Power Solution to a Brighter and Greener World
Grid Tie Inverters
A grid-tie inverter (GTI) is also known as “synchronous inverter” or its technical name “grid-interactive inverter”. It cannot be used in standalone applications where utility power is not available.
This is a special type of power inverter, that converts direct current (DC) electricity from the solar panels into alternating current (AC) and feeds it into an existing electrical grid.
It works by regulating the amount of voltage and current that is received from the direct current solar panels (or other renewable energy/DC sources).
. During a period of overproduction from the solar generating system, power is routed into the power grid, thereby being sold to the local utility provider.
. During insufficient power production from the solar generating system, it allows for power to be purchased from the local utility provider.
How is a grid tie inverter different from other inverters?
The main difference between an inverter and a grid-tie inverter is that the latter also ensures that the power supplied will be in phase / in sync with the grid power.
This allows residences and businesses with surplus solar power to sell the power back to the utility. This is sometimes called “spinning the meter backwards” as that is what literally happens.
“Net metering”, is where the entity that owns the renewable energy power source receives compensation from the utility for its net outflow of power.
