1800 inverter
Ok so I've read different opinions on leaving the inverter on when connected to shore or generator. Some say you must turn off and others say it's passes thru the inverter with no harm. This is on a 2018 model Windsport . A lot easier to leave it on all the time.

Leave it on, it is designed to be left on.

As Laco said - designed to be left on - the question is do you want the inverter to start supplying power if the AC fails?
If so - leave it on...
If not - turn it off.

Our 1800 watt inverter has never been turned of in three years. The only problem will be the fan. Unless they are using some kind of super long life fan. The bearings will start squeeling.

May not be a problem. Not sure the make and model of the Inverter, but the fan may not run all the time. It may only run based on temperature or load?

On ours the fan will only run intermittently, when the temp sensor calls for it. All that I know of work that way.

True fan only runs at some set temp and above. But it is in enclosed compartment so all heat the inverter generates stays in the compartment causing fan to fun more. High probability that fan will fail before any electronic component and then inverter design will matter. Hopefully there is a fan monitoring circuit and it will shut the system down with a fan fail code. I spent a good part of my life in computer repair and fan failure was most often cause of other more serious failures. So should you leave inverter on when not being used - NO. Shutting it off during periods of storage will improve odds of not having a failure.

I'm a retired IS director, so have some knowledge of circuits etc. too. I doubt there is a fan sensor, but I would bet there is a thermal protect circuit that will shut the invertor off should it overheat. Mine too is in a compartment, but even in warm weather the fan probably does not run more then between 50 to 60% of the time. Its nothing I am going to spend any time worrying about, mine stay on all the time, which is the way its most convenient for me to run it. If it fails I will deal with it, until then I wil use it.

Speaking of inverters...
If you've got a 1000 watt unit in your rig: is there any advantage to be had in upgrading to an 1800 watt version?

Would give you an additional 800 watts of available 120 volt AC power. If you need it, yes it would be worth upgrading, if the 1000 watt inverter is sufficient for the way you use it, no reason to. That additional 800 watts, though useful if you need it, if you use it, will drain your batteries faster.

Thank you; I hadn't figured on draining the batteries faster.
