Fully Refurbished Sunny Boy Inverters.  Simply replace your broken unit with an exact model.


These units are fully refurbished by former SMA Technicians, and come with a 60 day limited warranty! 

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.


700U, 1100U, 1800U, and 2100U supplies limited. Order while you can!



 Use the SB 700U for small starter systems, educational, or demonstration projects. Field configurable for three output power ranges, this small inverter will allow a PV installation with as few as three solar modules. It's great to fill tight spaces, or as a solution for challenging roof topologies. Just like every other Sunny Boy Inverter the SB 700U can be configured for all of the communications options available. Which means you can combine them with any other SMA inverter and access the data in one central location. As an added advantage, the SB 700U has a new control board that allows for any remote communications option to be used simultaneously with the Sunny Boy Display! The Sunny Boy 700U was SMA’s first mass-produced string inverter and it continues to enjoy immense popularity in today’s solar market. Its compact size and economical price make it ideal for starter or demonstration systems. It is also perfectly suited for adding a bit more power to an existing solar system. Its modular design makes expansion to almost any size system easy.Three different configurable input voltage ranges make the Sunny Boy 700U a versatile choice, whatever your system configuration.

 Connect your Solar PV panel arrays to the grid for net metering applications. The Sunny Boy 1100U is rated for 1,100 watts of AC electricity to be feed back into the grid. This Sunny Boy 1,100 watt String inverter is designed suitable for smaller and medium sized Solar PV-systems. The Sunny Boy is Developed for a DC power of up to 1250 Wp the Sunny Boy 1100U is one of the compact-line inverters. Sunny Boys are designed to be safe in the field, and easy to interconnect.


Simpelest plant design and easy installation for lower Balance of Systems costs.

No DC distribution boxes are necessary, using this direct connect system.

Monitor your system with Powerline communication or data cable (RS232 or RS485) options.

Operation conditions, -25 °C to +60 °C for extreme environments and sites

Enclosure classification IP65 (NEMA 4x), suitable for outside installation, a big plus.

Connect the DC side of your Solar PV panel array with Multi-Contact snap-cable connectors, for ease of installation.

The Sunny Boy connects to the AC grid with waterproof plugs. The Sunny Boy Solar grid tie inverter 1100U for professional grid tie AC power applications. Reliable and well proven in the field, the Sunny Boy offers you robust Grid Tie inverter power and solar energy.





 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.

Sunny Boy's unsurpassed reliability and efficiency are the result of SMA's manufacturing philosophy that combines simple design with robust execution. SMA's state-of-the-art maximum power point tracking performance results in greater real-world energy capture than any other grid-tied inverter. Sunny Boy's safety and reliability record is also exceptional due, in part, to the inverter's redundant grid monitoring and built-in ground-fault detection and interruption protection. The inverter's IGBT power stage generates a nearly perfect sine wave with the lowest harmonic distortion in the industry and meets ultra-strict FCC EMC standards. SMA's unique String Inverter technology makes future system expansion simple. SMA advance communication options are available to satisfy almost any application.
