A division of Solar CowboyZ, which is now referred to as You Love Solar ( ) specializes in refurbishing out-of-warranty inverters (Gridtie SMA SunnyBoy and Offgrid Trace/Xantrex power inverters).  

You Love Solars’ inverter repair department began operation in 2013, using original in-house service technicians, trained for many years at the original manufactures facilities.  These technicians have made a career of professionally repairing and upgrading the power electronics inside these inverters, in most cases, “to better than” original factory specifications.

 With the introduction of the SB 1800U in the US, SMA now offers more flexibility for small residential customers. The 1800U's 120 Vac output is perfect for most homes and small businesses. It's lower total output power means that very affordable and low cost systems can now be achieved.

 Sunny Boy inverters are housed in a watertight stainless steel outdoor enclosure, and can operate in extreme conditions (ambient temperatures of -13ºF to +140ºF). They can even be mounted right on the roof along with the modules.

 The Sunny Boy is designed to support PV modules in series, increasing efficiency and eliminating the need for expensive DC distribution systems and cabling. The Sunny Boy inverters increase efficiency further because they run a separate MPP tracking for each single string. Each Sunny Boy inverter is equipped with a separate and autonomous grid monitoring facility that enables the user to hook up the AC output to any point within the electric distribution system of house.
