Whywe produced theGTI-L --- It isin response to theoverwhelmingclamorfromour
customersfora product that can controltheamount ofpowerthat thegridtie inverters
(GTI)cangenerate sothat theamountofexcess powerproduced bythe solarpanels
are
reducedtoinsignificantlevels, if not eliminated---because in somecountries,
theproducerpaysfortheexcesspoweritgivestothe distributiongrid. This
is becausethe electric powermeters(theone providedbytheelectricityproviderinthe
area)arenot aware ofthedirection ofpowerflow.Inotherwordsitonlyaddseven if
poweris exported to the grid,thus, the consumerswill be chargedforpowereven if itis
given to thegrid,andthisistheproblem
This isthe 2nd generationGTIL ofMasspower.The first generationGTIL mustbe used
withan additionallimitermodule,wealsoadd answitchbuttontoenablethe inverter
eithercanwork
at limit mode orat normalgrid tiemode. With the 2nd generation GTIL,we integrated the
limit functioninsidethe GTI-We callthisinternallimiter.In this way,Noadditionallimiter
moduleis needed,reduced customer scost,more easierforinstallation.Butin case
customerinstall inverterfarawayfromthe main circuitbreaker,wealso enable the 2nd
GTILworkwithstand-alone limiter,we callthis-externallimiter.Forsure,the invertercan
workundernormalGridtie-nolimitmode,just setontheniceLCD andsaveyoursetting.
