Hi, we have strange issue. We have installed many Multiplus II's but never experienced this. The multi is AC output1 is connected to a backup circuit via a changeover switch. The AC1 input is connected to a breaker on the main board. What is happening every now and then is the AC main board is shutting down for a few minutes. This turns off all appliances which are not on the backup circuit. It must be an issue with the inverter because when we turn the inverter off, this doesn't happen. Has anyone else had this issue and found a solution?
Thanks,
Greg
