SMA 5000US which, when it wakes up every morning, removes the date and time from the programming in the customers' Monitor brand kerosene heater. They have to re-enter it daily, which is annoying enough, but when they go out of town, they have to leave the inverter off to avoid coming home to a cold house. So far SMA has had us move the breaker as far as possible from the heater breaker, to no avail. They had no other suggestions. I used a Panamax plug-in power conditioner with 50 dB of EMI filtering on the heater outlet, which has reduced the frequency of the problem to once a day, when it wakes up, from a few times a day. Trying a different heater is out of the question due to cost, so I'm stumped as how to avoid an unhappy customer, unless the answer is experimenting with more robust power conditioners.
