After several years of deliberation we have recently taken delivery of a new Burstner 690g. After a couple of days getting familiarised it was apparent that there were no lights flashing on the Teleco solar controller under the passenger seat. We took the van back to the dealer who determined that the wiring was reversed. This was corrected and the leds now light up. However, the 100% light is constantly flashing and never settles. I assumed that once the battery was at 100% the led would stay steady. This happens even when the van has been on mains hook up overnight at which point the battery should be fully charged. just thought I would ask before talking to the dealer again.
