SMA America Inverter Monitor

SMA America’s Sunny WebBox collects and uploads data to the Sunny Portal Web site through a wired piggyback card installed in each inverter. Weather station sensors can be added to the Sunny WebBox.

The company has recently re-engineered and reintroduced the Sunny Beam wireless device, switching from cordless-phone radio technology to a Bluetooth card in each inverter to improve the integrity of the signal. But I have found distance limitations on the signal strength when walls or ceilings are between the inverter and the Sunny Beam. An integrated solar cell can keep the monitor’s battery charged.
