  • Post in thread: Bluetti AC200P directly to DC Panel?

    Thanks WSix, yes I realize that, however, being the inverter is 87% efficient, I’ve researched it’s best to use the DC output if you can. Since this unit has a 25Amp, DC output, with an available adapter I can purchase, I’d like to wire it directly in to my RV’s DC panel with a switch over...
  • Post in thread: Who’s the Boss!

    Gotcha, so the fact that the alternator and solar charge controller, (and converter/charger), are physically connected, the amperage and voltage they put out is based on the battery state of charge, and doesn’t get measured by each other? So it’s ok to have the solar charge controller on going...
  • Post in thread: Bluetti AC200P directly to DC Panel?

    I’ve decided to go with the Pecron Q3000S. More KWH for the money. I also wired my TV so I can just plug right in to the power station while keeping it inside my RV so no need to tap in to my DC panel. Although it’s very slow charging rate, when I plugged it in to my RV I didn’t even use half...
  • Post in thread: Who’s the Boss!

    I actually found this video, I follow this channel once in a while. He kinda explains it. What a system! 300 amp alternator! (Holy Cow!) I would think this is how every system should be setup, this makes more sense to me. Everything communicating with each other. Even on a cloudy day he’s...
  • Post in thread: PWM Confused, please help!

    Lol, I’m on my 3rd rig with LP/Absorption fridge, I’ve had it with them all! To finicky, can’t deal with the temperature swings, so we are Going to 12V. My wife’s scared to death of all the propane fires she occasionally hears about. She has pushed me “to the 12V side”! Recently I purchased a...
  • Post in thread: Panel calculations

    I’m also trying to figure out the best and proper location to fuse the panels; 1.Fuse them after the wiring exits my cable entry gland in my dry storage, before the solar gen? 2. Or Should each string have its own fuse? 3. Or Fuse the main line before it enters my cable gland on my roof...
  • Post in thread: I’m new, have research questions

    Spice was a TypO by auto correct I guess, it should have been all the “above” appliances. I didn’t know the furnace blower fan was DC. If this is the case than I can buy something like the jackery solar generator all in one! how do you suggest I wire my mobile router and TV to 12V DC?
  • Post in thread: PWM Confused, please help!

    I downloaded the manual to my charge controller. I noticed it does not have a grounding post on it. Should I ground the body of it to my chassis using one of the mounting holes with a cable?
  • Post in thread: Auxiliary Panel wall socket?

    If I wanted to add an additional solar wall socket to the outside of my RV, to plug in an additional, foldable, portable panel system, how do they get wired to my roof panels if I have a 15 amp, rail mounted, PV breaker after the roof panels, before my solar generator?
  • Post in thread: Connecting Solar Generator/Portable Power Supply To RV Inside the RV

    Yea, that’s an issue. Unless you use another heat source that’s isolated from your RV. I have a large, Mr. Buddy, LP potable unit. It runs on 2-1lbs LP tanks. I’ve previously used it to quickly heat up our vacation home in the winter when we arrived with the heat on low, I would quickly blast...
  • Post in thread: Panel calculations

    Hello, I am new to solar. I’ve been doing a lot of research and want to make sure I’m doing this correctly. I just purchased a power station/solar generator for my RV which has a specific specs for panels; 300w max, 30-40V range and 10amps. I found a great flex panel that’s reasonably priced...
  • Post in thread: Auxiliary Panel wall socket?

    Well, actually, I’m in a crunch, I have to go out west to settle a few things. I’m leaving in a few days and don’t have time to mount them on my roof. So I figured I’d just put a port outside, plug the panels in if I need them in a pinch. Don’t know if I’ll even need them, just want to be...
  • Post in thread: PWM Confused, please help!

    I kinda get we’re you guys are both coming from, but to be clear, for MY application, if I were to fuse in a 2S2P string, it would only be one on each of the + legs of the Parallel side? However, any system less than a 3 panel parallel string does not need fusing? Just looking for clarification.

  • Post in thread: I’m more confused, please help!

    Yea, but sometimes I do overthink things! It’s not a bad trait! I have a SCC question, while I’m here, over thinking!, my SCC settings do not have AGM as a charging profile, there only SLA, Colloidal-LA, Vented-LA, Lipho and Custom. So which should I choose? I have it on SLA right now.
  • Post in thread: Ecoflow/Bluetti Home Backup vs. EG4

    JAS, you stated that if you went with an Eg4 system you’d need to do “preferred fireproofing”. What exactly are you concerned about and what would you need to do for this fireproofing? I’m very interested in knowing if this should be a consideration in my system. Right now my biggest concern is...
  • Post in thread: Bluetti AC200P directly to DC Panel?

    Hello Everyone, after much contemplation, I’ve decided to purchase the Bluetti AC200P instead of installing a full solar system in my 30amp, 2019 class C RV. Mostly because we will be selling and upgrading to a new rig within 2 years. Having said that, I’m looking into connecting the Bluetti...
  • Post in thread: Which to choose? Between 2 150ah LifePo4 batteries

    Searching this forum and ready through this thread, I too am looking to install one Sokerdy 160Ah with a claim of a 160A BMS! As a house battery for my RV. So has anyone on this thread had experience with them? I’m concerned about enough cranking power to start my generator too. I looked at...
  • Post in thread: Should I worry about a draw on my battery from charge controller overnight?

    Thanks Redneck, Yea, I’m always careful with disconnecting PV first and reconnecting PV last, that’s why I put a 2nd breaker in my compartment for my battery, next to the PV beaker, even though I have a fuse at my battery, the battery is under my steps, a pain to get to! SCC is off right now...
  • Post in thread: Connecting Solar Generator/Portable Power Supply To RV Inside the RV

    Straight to DC is definitely more efficient. Especially if you’re going to dry camp a lot, that’s probably your best bet. But I found without using air conditioning and hardly even doing any type of conservation. I’m able to get 3 full nights out of my solar Gen without solar or any recharge...
  • Post in thread: I’m new, have research questions

    Awesome thank you
  • Post in thread: Ecoflow/Bluetti Home Backup vs. EG4

    Thanks JAS! Yes, the Eg4 looks like it’s more cost effective. I have to keep researching. I would like to take the 200amp grid power, connect it straight into an all in one device, have it go back out to feed the main panel, and be autonomous. I just watched Wills video on the Eg4 18KPV. This...
  • Post in thread: I’m more confused, please help!

    So I’ve already posted about my recent install of my SCC to complete my small 200 W solar system. And I’m all good with everything, except these other questions; I also went and purchased a new, 92 Ah AGM house battery to upgrade my 4.5 year old, 66 amp hour, lead acid one, (it was the biggest...
  • Post in thread: PWM Confused, please help!

    Great info! Now I fully understand, you explained it perfectly, Thanks. What about a fuse/breaker between the 20amp solar controller and the battery? I found through a little research it’s recommending 25 A. But I’m not sure if that’s correct?
  • Post in thread: Auxiliary Panel wall socket?

    Not a secret! Lol, 17.6V x 2=35.2V 2.80A x 3=8.4A 50W x 6=300W And I’m trying to stay around 40V, not exactly 40V, don’t want anything excessive because of solar charging specs. I just didn’t think it was necessary to include all the specs since there will be no panels on the roof while the...
  • Post in thread: PWM Confused, please help!

    Thanks, yes I am using 10 AWG and the run is under 5’, more like 4’ Thanks again for all your advice and information and help. I truly appreciate it and appreciate forms like this very much. I’m on other types of forms And try to help people with my knowledge and experience as well. I always...
  • Post in thread: Panel calculations

    yes
  • Post in thread: I’m new, have research questions

    How far from the batteries can an inverter be located?
  • Post in thread: Should I worry about a draw on my battery from charge controller overnight?

    Thanks Substate. I was at my rig today till around 12pm, the highest I pulled in was 80w and 2amps! Even with my meager 200w panels it’s worth keeping on the solar charge/controller?
