Mounting the mppts on a stand off to improve rear clearance would be helpful. Also a little more space between the breaker box directly above the mppt could be an improvement. Cerbo has up to 4 temperature inputs that could trigger the fans. Mount the sensor to the mppt chassis ground on the...

RVs can be tricky. Many small RVs cant fit enough Solar to runs 48 volt system. The large ones that can, have to run 2 or 3 48/12/30 amp converters to run jacks and levelling systems. But can run panels in series make 48v work. I'm running 24 volts, easier to convert back down to 12 for jacks...

It does not have any integrated breakers or bus bars. Ill be down there next week and can grab some pictures. Has large xantrex DC panel with a breaker for inverter and flex max 60 SCC. I have been flip flopping on the 48v system idea. Need to spend some time down there and feel it out...

Waiting for a 12/24 volt version to become available. Looks great! The adjustable output is really handy.

Our dishwasher is ok, we only run it on opportune days. We feed it from a propane on demand heater which helps a lot. However, part way through the cycle it tends to turn on the heater element and start pulling around 1100 watts! hoping to pull it out and try and disconnect the heating element...

Are you running an inverter off the 48v? Would be easiest to buy a good 120/12v charger and run it off the inverter. To run the buck converter you just need to run heavy enough wire for the buck converter at the 48v side and fuse it appropriately. Math following... 20amps @ 13.6 volts is 272...

dollars and weight, RV builders worst enemies...

Your on a 48 volt system right? Looks like you'll need a 500v controller with potential for 125 amps of charging at 48 volts. The EG4 one would be slightly over paneled with the 100amp charge output. Shouldn't be the end of the world in the PNW as our sun sucks anyways. There is a Schneider...

I'm going to run two charge controllers in my truck camper to minimize shading effect. Worked great in my last trailer and two 20 amp controllers where not any more expensive than the 50 amp I would have had to run with them in parallel.

If you can't get rid of the shase...I'd put the portable array on it's own mppt. Then the portable panels are not getting nerfed by the shaded roof panels. Roof panels on parallel could help the shading up there. But 4 in parallel would require fusing I believe.

Blues seas makes a 1000 amp bus bar, 12 5/16 posts on it 6 and 6. Could run 5 batteries up from the bottom and 3 pairs of inverter cables up from the top. Leaves one extra input and has a few small studs for other connections. Not sure if its something you can get shipped in...

There are a couple switch kits for high idle, tuner not required. Can also use an upfitter switch and resistor wired into the factory harness for high idle. There's a chart to pick resistor ohms for "X" rpm. Set the shunt to DC meter if hooking up to a cerbo. If I see a good deal I'll grab a...

Yes, as long as your solar charge control input voltage limit is not breached. You could have 5 24v panel in series on a 150 volt controller for 120 volts in and it will pump out 12 volts to your panels.

Pair of SOK 24v 100AHs would work. 100amp BMS in each or a single EG4 24v 200ah but that only gets you a 100 amp BMS to run the inverter that will draw 100 amps at max load, potentially more with a surge load. This is based on my limited knowledge and recent research on running my multiplus...

Ive got a bussman 60 amp breaker((oversized breaker for engine temps) under the hood for my 12/24/15 and 6 gauge wire (ancor marine). I will add a continuous duty solenoid that is controlled by the upfitter. This way it shuts down when the truck shuts down (i didnt get the smart version...

If using 4 3.2v cells then yes 12v. I believe the original comment are around using 12v battery assemblies in 4s4p for 48v total. With proper bus bars and cabling you should be able to stack many 48v batteries in parallel. SOK has a rack for ten...really it's the bus Bars that would limit...

Going to 48 volts forces a high voltage series string for solar. This can be challenging for some RVs due to panel placement and shading issues. if you park in big open areas and have an easy roof to mount panels then it should work. In the pacific northwest this could be a challenge...arizona...

A rack of eg4s, 4 for the cabin and 2 for the RV. That would be overkill for my systems for a while.

What else is planned? inverter, size if so? lights? fan? airconditioner? That will help you make your decision

You will need to do some more panels in Series. Parrallelling that many panels is a wiring night mare...

Sad that I missed the 24v refurbs a couple weeks ago...stalking continues.

I missed that it wasnt a smart charger, not sure on that. Personally, i would use it but would have it switch controlled so it was off when i didnt need it running as it will push 9 amps all the time. The 12/12/18 is also too big. Unfortunately they cannot have the output current lowered, so...

Ive seen chatter in the marine forums about UL listed batteries being required by insurers...not sure if that matters to you, just throwing it out there.

Dam sold out of the refurbed 24v eg4s already. The V1s are on sale and tempting me...

Victron doesn't like your panels in 4s on the 250/100. Open circuit voltage could be higher than 250 in cool weather. Are they flat mounted? That definitely knocks down the output (not necessarily the voltage) to where you may never actually get the wattage. So a 100 amp controller might not...

Mine balanced up ok at the top, i did keep charging voltage low at first. Started at out 3.40 volts per cell and crept up over two weeks to 3.6 in small increments, did have quit a few high cell voltage alarms throughout that process but none since. If the battery sits for a bit they seem to...

Ill be buying a pair of 24v eg4s in october/november...where are you located?

If you are in western Canada KMS tools has 2/0 welding cable handy.

So would battery hook up be selling new, but B grade CALB cells as well? They have some odd AH sizes right now that may indicate they where supposed to be "X" capacity but fell short? I'm considering the CALB 180ah cells for mobile application.
