Just sitting there idle it's about 30W so not really anything to write home about. If it gets too hot it will let me know.
What coffee maker are you using? I tried mine for a minute the other day(keurig about 1400 watts) and it was a load on my gc2 Trojans

It's a Mr Coffee I got at Walmart for about 30 bucks. I measured it at right around 1000W at point of load using a Kill-A-Watt. My homemade battery handled it great. It registered a peak of 102A, which included the inverter and all the 12V stuff in the rig at the time.

I believe if you had a volt meter inside where you can monitor your batteries while using a coffee pot you might think twice about using high amps small Appliances . It freaks me out to seeing my 3 AGM 12 volt batteries hit 12.3 when using the toaster.

Just curious, the way the panels are mounted....can you angle them the other way? IF you park your trailer so your door is south its great, but what happens when your site forces you to park with your door to the north?

Yeah I saw a mainstays brand. Walmart brand probably that is 700 watts. I may try that

Pretty damn cool install.

I am hoping for some solar power in the spring. Mine will not be anywhere as neat as that!!

I will only have 4 X 100 W panels, but, they only have to keep the batteries topped up for the lights, fridge and furnace fan, charging cameras and tablets.

Yeah my victron alarm went off because of voltage drop so it kinda freaked me out. I should have been watching via Bluetooth.. keurig is just to much of a drain

When I built the battery I installed a Thornwave bluetooth module and an LCD display on the front, so I can get realtime data and history on my phone as well as a nice display for when I have the battery out for ham radio or other stuff I can use it for.

Here is what I get in the realtime display but it does show the peak current. I haven't played with the chart recording capabilities of the module but maybe I'll do that next. Generally though I designed this battery to comfortably supply 200+ amps so I'm not worried about anything the RV is going to throw at it.



And here's a picture of the display at 130A. It dropped from 13.2 to 12.9V, which isn't that much at all given the current. That comes to about 2.3 milliohms internal resistance.

Nope, unfortunately they don't swivel. So, I just have to hope I can get some sun. If I install more panels I will have to do at least one of them 90 degrees off from those and will have some on the other side of the apex too, so we'll see how it works out. If I am out boondocking somewhere I am hoping I will have some greater freedom in positioning the rig.

Really nice. I have a renogy 200 watt suitcase panel for now. I’m going to add a panel or two to the roof and use the suitcase to supplement. I’m thinking of getting the rover mppt charge controller with Bluetooth.

Thanks, love the setup. I was just thinking of doing something similar next spring but the option would be to pin one side with clevis pins and move the verticals supports to the opposite.

I need to switch these out to clevis pins as well... the thumbscrews and wingnuts are so slow and make it a real chore to set these up. Clevis pins would be much easier to deal with.

the mppt controller has some of those settings that are cool. I'm using this volt meter now that has on off switch. The camper is in a poll barn, I need to have the 4 amp charger on all the time. The aims inverter has on off switch above the meter. I leave the inverter off until I need the toaster or watch TV.
