I have a customer who is a little concerned about EMF radiation from her SMA SB7000US inverter.
It has a radio piggyback card and antenna installed which communicates with a Sunny Beam (tabletop display unit) wirelessly.
(Perhaps some of you remember this nifty little device. It has a built in mini solar panel!)
The inverter is on the exterior of her (stucco) bedroom wall, while the Sunny Beam is in the house on the other side of her bedroom.
I dug up the manual for the Sunny Beam.
I found this:
868 MHz acc. to ETSI EN 300 220 Duty Cycle < 1 %
What does "Duty Cycle < 1 %" mean?
How would this compare to a standard household Wi Fi router?
How would the net energy emitted compare?
Is it safe to assume it emits nothing at night (no solar energy)?
