Hi, last night my SI6048 shut down abruptly with W212 (high battery temperature warning) F206 (battery over-temperature) warnings - restarted it and it did it again (x3). Finally, after using an IR thermometer to make sure my battery wasn't really hot (72.4 degrees F) I disconnected the battery temperature sensor. Now I get W723 (cable break on battery temperature sensor) errors so fast I can't clear them (looks like 6 times a minute perhaps) but at least we're still making power - with thousands of W723 errors.
I had the W723 (cable break on battery temperature sensor) and W722 (short circuit on battery temperature sensor) error last year (that somehow managed to correct itself while I was waiting on a response from SMA) and had requested a new Battery Temp Sensor unit (was willing to pay for it) but they wanted to do the drag-ass warranty thing with me sending in operating files and all that jazz. It started working ok, so I dropped the ball.
I'm trying to find another temp sensor that will work - apparently SMA doesn't sell them in this country, and when I contacted the UK they didn't want to ship one to the US. SMA called it a KTY type sensor.
Ideas?
