Rocklin, Calif.-based SMA America Inc. has introduced specially configured Sunny Boy 4000US solar inverters for use on homes with 100 amp electrical service. The solution was initiated based on customer feedback and is designed to provide installers with more flexibility on residential retrofit projects, the company says.
The electric current output of the custom Sunny Boy 4000US inverters has been factory-reduced to 16 amps to comply with National Electric Code standards while providing installers additional system sizing options.
While 200 amp service is the current standard, many older homes have a 100 amp configuration, creating array sizing challenges for systems between 3 kW and 4 kW Previously, installers were faced with upgrading a home's service to 200 amps, which can be costly and time-consuming, or restricting the solar system to 3,000 watts, SMA America.
The current-reduced Sunny Boy 4000US will come pre-configured with 16 amp current output, the upper limit for 100 amp service, and will provide installers with additional power versus the Sunny Boy 3000US. Installers can place orders for the new configuration through their current dealers and distributors.
