There are many different solar grid-tie inverters on the market today; all
with different features, power ranges, options and prices. The most
popular units that we sell are from Xantrex, SMA, Fronius, PV Powered &
Sharp. Regardless of which of these inverters you use, multiple inverters
can be setup for use with a large solar array and wired to your existing
AC breaker box. If you are planning to install a grid-tie PV system, the
solar array and inverter need to be carefully matched to ensure that the
inverter’s voltage and power limits are not exceeded. Please look over the
grid-tie inverters below and then give us a call so we can discuss the
details of your system. We will make sure that your proposed solar array
will fit on the space available, that the physical layout of components is
optimized to facilitate easier installation, that the system will produce
the amount of energy you are expecting and that you get all of the
incentives, rebates and/or tax credits available in your state.

SMA Sunny Boy grid-tie inverters
The Sunny Boy line of grid-tie inverters from SMA in Germany are the
most popular units in Europe and have cornered a large portion of the US
grid-tie market. With over 250,000 units installed worldwide, SMA has the
experience and know how to create rock solid, super efficient grid-tie
inverters. In the US market they offer units ranging in power output from
1800 to 6000 watts and these units are modular so you can have multiple
units operating in parallel for large solar arrays. Their SB 1800U
inverter has a 120 VAC output, peak efficiency of ~93.6% and can be
ordered with or without an LCD display. The SB 2500U is available with a
240 or 208 VAC output (maximum output is lower when connected to a 208V
3-phase system), has a peak efficiency of 94.1% and can also be ordered
with or without an LCD display. The SB 3800U is the newest addition to the
Sunny Boy line of inverters and it features a new Opticool™ airflow design
and outdoor rated NEMA 3R cast aluminum enclosure. The SB 3800U comes
standard with an LCD display, has a peak efficiency of 95.6% and can be
ordered with a 240 or 208 VAC output (lower output rating at 208V). The
largest SMA grid-tie inverter is the 6kW SB 6000U which comes with a
standard LCD display and can be used with 208, 240 or 277 VAC systems with
its automatic voltage sensing capability (lower output rating at 208V).
All of the SMA Sunny Boy inverters have built-in ground fault protection
(required by the NEC for roof mounted solar arrays), but none of them have
integral DC or AC disconnects. SMA also offers a wide range of controllers
and displays including the new Sunny eam which can remotely monitor the
performance of up to 4 Sunny Boy inverters without wires. All of the SMA
Sunny Boy inverters are covered by a 5 year warranty with an optional 10
year extended warranty available. Please check out the pricing in the
chart below and click on the links to the PDF spec sheets for more details
