Hi all,
I've just installed a Multiplus II 48/3000 in my kitchen and while it works as advertised, the transformer hum is pretty loud. The inverter is silent when inverting, I've also verified that it's not the charger responsible for this hum. There are reports online of others suffering from this but I have yet to find a solution, I'm wondering if anyone here may have found a workaround before I relocate this inverter to the garage.
Thanks
