Grid Tied Systems
Our Solar grid-tie PV power systems are designed for use on residential and small commercial buildings. They consist of high quality Evergreen, REC, SolarWorld or Mitsubishi photovoltaic (PV) modules, a Fronius, SMA, PV Powered or Xantrex inverter, array wiring, DC and AC disconnects, Unirac mounting structures to secure modules on the roof, electrical drawings, data sheets, warranties and instructions.
Some Xantrex and SMA inverters have integrated DC disconnects. Systems that list “ST7000” as the inverter use the new SMA Sunny Tower 42 kW tower that consists of 6 SMA SB7000US inverters, pre-assembled on a stainless steel structure.
Wiring from the array to the DC disconnect, array ground wiring, and wiring from the AC disconnect to the main panel and all conduit must be supplied by professional installers (your specific installation or utility may require additional AC disconnects). Contact us to obtain these essential resources and expert advice on your system installation.
All components comply with the 2005 National Electrical Code (NEC-2005); IEEE Std 929-2000, Institute of Electrical and Electronics Engineers Recommended Practices for Utility Interface of Photovoltaic (PV) Systems; UL 1741-Underwriters Laboratories Standard for Safety; and the ICBO 2000 International Building Code. The arrays and inverters are matched for maximum efficiency.
These modular systems can be combined to form larger systems to meet your requirements. It is economical to put these systems together for use in 30 kilowatt or smaller systems. For larger systems, please ask us for a quote.
Select a pre-packaged system that meets your needs from the accompanying table. California Energy Commission bases rebates on the system CEC rating in column 4 of the table. CEC’s calculation takes into account module output in normal operating conditions and inverter efficiency.
