Standard Features:
Sun TieUtility interactive inverter, 240 VAC 60
Hz output. Includes factory installed DC and AC
input/output breakers, combination DC and AC
lightning arrestor.
Options:
STRSProtective rain shield, required for out door
installation of ST Series inverters
Certifications:
UL ListedThe Sun Tie is UL Listed to UL 1741
and cUL Listed to CSA 22.2 No. 107.1-95. The ST is
designed to comply with IEEE 929.
Note:
ST1000 and ST2000 models do not include PV
ground fault interrupters and PV combiner boards.
Trace offers a PV ground fault interrupter (PVGFP)
which requires an enclosure (not included) and a UL
Listed 10 circuit combiner box (TCB10). Both of
these items can be ordered separately.
Connecting The Sun To Your Utility Meter
Introducing the Sun Tie
All-in-One Design
All NEC (U.S. National Electrical Code) required DC input and
AC output connections, disconnects and circuit breakers are
housed within the Sun Ties compact case. A built in LCD panel
provides easy-to-read system status and daily cumulative power
production information.
Works With Any Type of PV Technology
The ST is designed to optimize the output from all types of solar
electric technologies. The open circuit voltage window of the
Sun Tie ranges up to 125 VDC so both conventional Crystalline
and newer Thin Film PV modules can be used.
Maximum Power Point Tracking
The Sun Tie uses sophisticated software to track and adjust the
output of the PV array. Our Maximum Power Point Tracking
(MPPT) software, which samples once a minute, ensures complete
harvest of the suns energy all day long.
Expandable
Multiple ST inverters can be connected to a utility grid so that
additional generating capacity may be added in a fully modular
manner.
High Efficiency, Long Life Design
The high frequency, solid state design of the ST inverter is
extremely efficient. The inverter efficiency is over 90%, with
peak efficiencies of 94%. Built and designed in the U.S.A. by
Trace Engineering, makers of the worlds most reliable inverters,
the Sun Tie is sure to provide many years of trouble free service
and carries a two year warranty.
* The Sun Tie is shown with optional protective rain shield which is
required for outdoor installation of the inverter.
T
race Engineerings new Sun Tie (ST) solar electric inverters are designed, built and priced to make the benefits of
site-generated PV power easy for anyone to attain. The Sun Tie operates interactively with the utility, without the
use of batteries. Made specifically for new, small-scale, independent power producers, the ST is a perfect choice for
anyone interested in participating in the emerging Green Power market. The ST is
available in four models with output capacity of 1.0, 1.5, 2.0 and 2.5 kVA.
Distributed generation, using the power of the sun, is a win - win choice for the
environment, utility companies and consumers alike. With this form of electrical
distribution, solar PV power is generated and inverted at the location where its used.
Solar electricity helps reduce the need for new large-scaleand often environmentally
harmfulgenerating stations and distribution lines.
Consumers can have lower electricity bills because any PV power they generate is either
used in their home or business or, when there is excess, sold to the utility company. Net
Metering is one way electricity is exchanged between the power grid and solar generators.
Net Metering programs are available from many utility companies, contact your local
electricity provider for details.
Utilities benefit from increased solar generation by gaining the ability to resell the PV
power they purchase to environmentally conscious customers at premium Green Power
rates. Consumer generated, solar electricity can also help utility companies meet their
growth requirements at lower capital costs.
