Thanks, Don. Did you secure the plywood in any way besides the screws?

Your welcome, glad I could help. I only used the mounting screws from the Trimetric to secure the plywood.

Some observations: Escape will gladly run the wire during the build process. On my 21 I choose the area above the stove, I would have selected the same location on my 19. The cable kit is 25 feet and there is not any issues with distance of wire run. Escape will not install the meter or the shunt, however these appear to be relatively simple processes using all the wires included plus you will need a battery cable (I believe but have not confirmed Escape uses 10 gauge wire for this) to run from the new shunt to the negative on the battery. The existing wire on the negative of the battery will come off and be on the other end of the shunt. I have in my possession and plan to upgrade to a 18" length of lawn mower battery cable, it has the smaller diameter ring connector on the 6 gauge cable and will connect properly to the shunt and battery. However, I will not have the Escape 21 in my possession for another two weeks so have not installed. The shunt will be within 18" of the battery

Escape has a relationship with WeGoSolar and all the items I ordered were never put on my charge card. Instead they were added to my build sheet as a part of the total package. I liked that.

I agree with all that WestEnder has written about location. Mine will be eye level and easily observed. Escape actually selected this area so I am going on some of their experience. I believe the cables will just be laying in that upper cabinet with hole drilling and final location left up to me. Perhaps it is possible to tack the cables inside that expanse of cabinet over the sink and stove and relocate it more toward the door?

I choose the Trimetric 2025 because the 2030 had been announced but was not yet available. I was interested in the SC-2030 controller as well. I am not sure that has shipped yet. I settled on a Blue Sky 30 as a replacement.

Did you end up ordering the controller as well? I see on their install instructions that a phone cable needs to be run from the monitor to the controller. I was planning on putting the monitor on my 19 in the front passenger upper cabinet end, but would have to have Escape run a phone cable back to where the existing Gopower controller is. Did you have solar on your 19? Where do Escape locate the controller on the 19, is there room to put the battery monitor there as well so I don't have to have them run the phone cable.

To connect the Trimetric 2025 and I assume the new 2030, you need one of two cabling methods. The cable kit from Trimetric, about $30 that has some ring connectors on one end and an inline fuse installed. I believe the other option is Cat 5 wire, perhaps phone wire would work but you may need the more pairs in Cat 5 or the better twisting of the pairs. Then you would need to crimp ring connectors and purchase a fuse. Either method allows long distance runs but the Trimetric cable is 25'.

I purchased the cable and the controller with shunt from WeGoSolar.

I have to think of the best method to install in a 19, someone else may add to this discussion. With the batteries on the tongue, I think the shunt would go into the drivers side dinette. All connections from the Trimetric go to the shunt, there is not a need to connect to the GoPower controller. So your only wiring need would be the selected cable from the shunt to where you wish to locate the monitor.

In this scenario you are going to remove the negative wire from the battery and install that on the shunt. You would need a new wire from the shunt to the negative of the battery or you may well be able to use the Escape installed wire. I cannot remember if the negative from the battery goes to a connector block in that dinette seat? You could just remove it and place it on the shunt, then install a new wire from the shunt to the connector block you removed the wire from.

I am not sure what Escape is using today for gauge of wire in this location but I would consider replacing with 6 gauge wire, it is not essential, just gives better performance.

I do not know where Escape locates that GoPower monitor on a 19. You could mount the Trimetric on the dinette seat between the WFCO power converter and bathroom wall. It might be too low to read easily. If your bathroom wall was reinforced it could go there, not sure I like that either. Higher is better in my mind, I think eye level has been mentioned several times. The upper drivers side dinette storage compartment seems like a good spot.

After reading that the shunt should be installed as close to the battery as possible, I chose to mount it on the battery case with 3M tape. I figured there was plenty of ventilation since the batteries are not in an enclosed box and corrosion won't be a problem; time will tell. I replaced the ETI cable between the battery posts with 4 gauge cable, the same size as cable from the inverter as well as using 4 gauge to connect from the shunt to the battery post. My local NAPA store cut the cables to the length I asked for as well as crimping on the end connectors to the cables.

Good idea to put the shunt in the storage box. I never had the box so it falls out of my knowledge base. How hard was it to route the Trimetric wire assembly/cable kit out to the battery box, or did ETI do that for you?

I like the battery cable upgrade, it is on my list. What about the cable between the batteries? Did you install that or Escape? What about the neat labels? My 19 had a piece of masking tape with + or - on it.

Routing the wire wasn't too bad. I followed the path of the wires from the GoPower controller to get to the area under the dinette seat. I didn't want to drill another hole through the floor so I removed enough caulking around the inverter wires to snake the wire from the Trimetric through the floor. I also used the existing wiring hole to route the Trimetric wire into the storage box.
I installed the larger cable between the batteries. The labels on the cables were applied by ETI. I carefully removed them from the original cable and reinstalled them on the replacement cable.

I've asked Reece to run the Trimetic wiring harness into the battery box, with plans on installing the shunt in there like Don did. The other end I originally asked to be left in the front upper cabinet passenger side with the intention of mounting the monitor on the end facing the door, but now I think it might be better to run it into the same cabinet where the existing solar controller is, I've asked ETI if there will be room. That way if I decide to change out the controller to the Trimetic, it will be easier to connect the 2. The specs call for phone wire, but I'll verify. Wegosolar don't answer their phone.

Saying the shunt needs to be closest to the battery means that the shunt needs to be the first thing along the wire from the battery before anything else is hooked up. It doesn't have to be physically right next to the battery. In the compartment where the stuff like the inverter, charger, solar controller and associated wiring is will be fine. That will also be a lot easier than trying to get the monitor wires out to the battery box. Also, problems with corrosion of electrical connections are much greater in the battery box which argues for having as many connections as possible of stuff like shunts outside it.

The only thing that should be physically close to the battery is the catastrophe fuse. Various electrical codes specify the maximum distance from the battery for that depending on installation type but the usual feeling is the closer the better. There are a lot of folks who put them right on the battery terminal when possible.

Those are some good pointers on shunt placement. It seems that Escape front storage box with batteries is a bit of a hybrid. Does it have vent holes like the interior battery box on the Escape 21?

Regarding the catastrophe fuse, is that used on the negative ground wire between battery and shunt or is this the fuse used on the wiring harness for the Trimetric? When you state fuse, would an automotive circuit breaker provide the same protection? Any idea of a range of distances that the different codes might specify for the location of that fuse?
