The Go Power wiring diagram shows the fuse as being between the Go Power remote start and the inverter. We do have a fuse at the positive on the batteries, but it is at the solar input. It reads 20 amps and is a bolt on. There appear to be no cracks in the fuse or holder. Our inverter gave a loud snap and has not worked since. Perhaps a fuse blowing? We just cannot locate the inverter fuse.

While there might be a fuse there (and could be the problem), it's not the main one that power for the inverter goes through. Only control signals will go between the remote switch and the inverter, not the more than one hundred amps of current required to run the inverter at full power.
What model of GoPower inverter and remote is this?

If it is 20 amps, that would be for just the output of the solar charge controller... or someone put the wrong fuse in for the inverter circuit. 20 amps is far too small for the inverter, and the wires between the solar charge controller and the battery are much thinner than the wires between the inverter and the battery.

If the sound came from the inverter itself, perhaps it was the internal fuse, or an internal component of the inverter; you won't be able to see that without opening the inverter case... and you probably shouldn't open that case.

First, I misread the fuse. It is the 200 amp fuse held between the + post, the large inverter cable and the solar cable. It is fine, the internal metal piece is solid as seen through the glass.
The inverter is the GP ISW 1500, the remote/solar controller is the Go Power Maximum. This is the stock setup installed by Escape, for the 170 Watt single solar panel, automatic transfer switch, 1500 watt inverter. Nothing has been modified, it is 6 weeks old.
The loud pop sound came from under the seat where the inverter is located. Unfortunately, we did not have that open at the time. The inverter had been working perfect until the loud snap, and we were not anticipating any problem. There was also a slight smell of warm wires. But nothing felt warm when opening the seat area, and the smell had dissipated.
Go Power is closed today as is Escape. We started searching the inverter problem Friday afternoon, Dave at Escape has never heard of an inverter problem. He referred us to Go Power. At Go Power the tech suggested the power disconnect and inspection of the fuse. We agreed to talk again Mon, but think he meant Tues.
Thanks to all on the forum about locating the fuse. We found it and it is good.

Although Escape has used Go Power products for a long time, this is a new model of inverter for them (the old one was discontinued): GP-ISW1500 - 1500 watt industrial pure sine wave inverter The only mention I could find in the manual of an internal fuse or other protective device was for input reverse polarity protection; if the pop sound came from the inverter as it failed, this looks like a non-replaceable fuse or fatal component failure. The manual for this inverter includes this statement at the end of the section about disposal at the end of the equipment's life:
Quote:
Note: The GP-ISW should only be disassembled at the end of its service life. Go Power! provides no spare parts for the GP-ISW.

I'm pretty sure that if anything has failed internally - even a fuse - it will need to be completely replaced (by Go Power under warranty), and should not be opened (so that they can open it and determine the cause of failure).
Assuming that the battery cables had not been disconnected before the failure, it cannot be a reverse polarity problem.
"Maximum" shows up on more than one Go Power solar charge controller, either as part of the functional description (maximum power point tracking or MPPT), or as part of the branding. This is presumably the same controller which Escape has used before: GP-PWM-30 - 30 amp digital solar controller This is PWM controller, and not a MPPT type; the "Maximum" is just branding for their "maximum power boost technology".
The GP-PWM-30 manual does not mention the ISW series of inverters (which are newer than that solar controller), and the ISW inverter manual does not mention compatibility with the GP-PWM-30 for remote control, which is a little disturbing - have I identified the correct solar controller/remote? Whether it is intended to be compatible or not, the connection between the two is just a modular cable (like a telephone cord) plugged into jacks on both pieces of equipment. There's no fuse in that, so what wiring diagram is this referring to?

With full light on the charge controller/ remote start you are correct. It is the GP PWN 30. The wires at the battery had never been disconnected, actually, we can say none of the wires in the trailer had never been disconnected prior to the inverter quitting. At the time of failure the batteries were at 13.6 V. The inverter manual shows a fuse on p.18 as a typical install. Guess that is only on the large + cable at the battery.
Tomorrow, we'll call both Go Power and Escape. Called a Go Power warranty provider in Fort Pierce, FL. Nasty, would be a polite description of our conversation. They do no work on Escape trailers and suggested we drive back to Chilliwack for service. All we want is a working inverter that we are willing to install ourselves.

Yes, the fuse shown in that diagram is the 200 amp fuse by the battery that you found; the cable between inverter and remote is that faint blue-grey line, with no fuse.

Contacting Go Power directly is probably the most productive approach. It seems reasonable to expect them to send a replacement, but I would expect to send the failed one to them first and to be without an inverter for a while. Page 34 of the manual gives the warranty procedure (which starts with calling Go Power), and Escape would presumably be considered the "place of purchase".

Go Power is sending a new inverter. They told us to dispose of the old one, not return it. Dave at Escape was very interested in the inverter failure, this is the first one that has failed.

Good news!
If you're curious, you can open the inverter and see what failed. If you do, be careful, because capacitors can hold a dangerous charge even after the power supply is removed.
