What is this box?

I'd like to be more specific but I don't know how to search for something I don't have a name for. I am looking for a way to route my solar panel wires and when I pulled out the bottom drawer under the stove, came upon this object.

Looks like a simple junction box.  Take the cover off and see what's inside?

Something else going on inside. Not just a junction box.

Some kind of solenoid switch?  Can you see where the wires coming in at the "bottom" of your photo terminate?

It just goes into the wiring loom. But I did what I should have done in the first place, started activating switches. I got the click when the electric heat for the Aqua Hot was activated. I have never been on hook ups or I might have heard it before. Question solved and if I ever have a failure on AH electric I will know where to start.

Yup, it is the 12v controlled 120v relay for the AquaHot heater supply.  It took me a long time to figure it out too.

I moved mine over to make room for a second small inverter that powers the refrigerator and the front end electronics.

That is probably what I will do also, the refrigerator power is right there. Not so sure how to get the tv, dvd player and audio on a separate inverter.

Chuck,

I believe Roger grabbed all front end in the picture and powers if fully with this small inverter. He will confirm I'm sure.  We took the exact same 800w Victron inverter and mounted it in coach battery bay adjacent to coach batteries and ran 120 output directly up into compartment above driver left (left of main Tv) and feeding a four outlet box with a on/off switch. This compartment feeds chargers for our phones and iPads and satellite antenna tuner.  From this outlet we also run a power strip across the front overhead compartments feeding main tv, Apple TV, HP mini computer, DVD player and satellite tuner.

All run well below this inverters capacity. And, with Victron's Bluetooth module on the inverter and our BMV700 monitor we can watch coach batteries and see load on them from this second inverter.

Not the only way...just what we did.

The U320 40' must be different as from my battery box going up would be behind the sofa. I was just there today and fishing a cable forward would be a problem. Getting from the floor up would be easy. I have thought about putting the inverter under the bed and running the circuit breaker output to the front through it.

That's what I did. Put a plug on it so could plug into inverter or regular sp/gen receptacle. Normally leave on inverter, when plugged in, batteries are being charged anyway. Mounted on fwd wall of under bed compartment, 12 volt from house side of isolator or 12 volt fuse panel.

We ran up at the rear end of the sofa into the overhead compartment and ran the 120v line under the "floor" of the overhead compartments to the front compartment over the driver left.

Our coach batteries are in the second bay driver side.

Every coach is different.  In mine I split one of the three inverter powered circuits that goes up to the front end.  The branch that goes to the front end and new outlets to power the refrigerator is hooked up to run off either inverter.  It took some doing to figure out which of the romex cables do what.  Once isolated the rest was pretty simple.

Don't forget a 120v circuit breaker for the small inverter powered circuit.
