- With shore power applied and breaker 5 OFF there is no power to the outlets until I set the remote control switch for the inverter to ON.  

- With no shore power applied until I set the inverter remote control switch to ON then the inverter supplied power to the outlets.

Yup

Website:

This is interesting:

From specs: 

Output Power
Protected by fuse: 12A/125V Circuit Breaker

From manual:

AC Circuit Breaker

The AC output of the WF-5110R Inverter, when in Pass-Through mode, is protected by a
resettable circuit breaker (see Figure 1 below). A 16A/120 VAC breaker is located on the
upper right on the unit’s rear panel. The breaker will trip in a high current situation. Should a
breaker trip, reduce or remove the connected AC load and reset the circuit breaker. Re-start
the inverter and check for proper operation

So the inverter is plugged into a single AC outlet that is a right next to it hidden.  Is that outlet always hot when shore power is applied?  I haven't opened up the area again to get back to the inverter to check with a multimeter.

Ok, so the inverter bypass circuit is getting power via circuit breaker 5. There is a 16A (or a 12A depending on which document you read) breaker on the inverter that has to be reset if you have a fault or overload that circuit. 16A is a kinda weird cb rating. What is the current rating of cb 5, they should have the same current running through them? 

When there is no shore power and you are running in inverter mode, the output is limited to about 1000w/8A continuous. There is apparently no cb for this mode, it is internally monitored by the inverter and is reset by cycling the power button off and back on. 

Over to the 12Vdc side. The unit is supposed to be supplied with minimum 4 awg wire protected by a 100A inline fuse. Did FR install that correctly? Hopefully the fuse is at the battery where it should be??? 

BTW, the 100A looks to be the correct number based on the 1kw continuous rating and the 86% efficiency, but 4 awg is too small for 100A, it should be 2 awg. Also, I would bring a spare 100A fuse along, fuses and cb's should be sized 25% larger than the continuous load they might see to prevent nuisance tripping.
