SMA offers greater support for 100 amp services
SMA is taking customer feedback and making proactive changes in their product line to serve customers even better. Recently the company modified their Sunyboy SB4000US inverter to be compatible with 100amp residential electric services. The current output on the SB4000US grid tie inverter has been reduced to 16 amps to comply with the NEC (national electric code) to provide more flexibility to installers to work on a 100 amp service.
Most homes in the U.S. have at least a 200amp service, although many older homes are stuck with a 100 amp service which can be costly and time consuming to upgrade. Having a 100 amp service can create a barrier to install a solar array between 3 or 4 kilowatts. With the modifications made by SMA to the SB4000US grid tie inverter, customers on a 100 amp service now have greater options on the size of solar array they can install using a SMA inverters.
The modified SB4000US inverters compatible with 100 amp services have to be special ordered since they are modified when the order has been placed.
