I am considering mounting two SmartSolar controllers in my engine room to get them as close to the batteries as possible. With the engines running, it may get as hot as 105 degrees in the ER. However, when the engines are running the controller will not be charging the batteries because each engine has a 150 amp alternator.
So I have two questions. First, Will the engine room operating environment harm the controllers? Second, can I use the VictronConnect app to disable charging and effectively turn off the controller when I am underway and won’t need the solar?
