Last week we started and also completed the development of a small but very useful assistant: ‘Silence fan’.
The fans in certain models of our Multi and Quattro Inverter/Chargers can be quite noisy, especially in the dead of night in your motor home, RV or boat; very annoying, we know. And since you have all night, it isn’t necessary for the Multi to charge at maximum amperage .
I am happy to present a solution! Wire a simple on/off switch to an input of your choice: the Auxiliary input or to the Temperature sense input. And add and configure the ‘Silence fan’ assistant. The motor home owner can then enable and disable the fans with that switch. During charge, the charger will reduce its output current. Not immediately, but only after the internal temperature has increased over the threshold. And when inverting, the Multi will have a reduced maximum inverter power. It will switch off and reach the temperature alarm faster. Because many people might be OK with a reduced charge, but still like to run the coffee machine without first having to remember the switch, we have added an option to only disable the fans in charge-mode.
Many thanks to our German distributor Transwatt, for their suggestions!
