    EPEVER, WiFi dongle AND MT50 monitor??

    Any EPEVER experts about.....The EPEVER ATN solar charge controller only has one RJ45 jack, currently occupied by the MT50 panel mount monitor. I want to add the EPEVER WiFi 2.4 dongle for remote monitoring. Is there some type of Y-adapter that will let both units work off the one RJ45?

    How Is This Possible???

    NEVERMIND!!!! After I sent this post, I thought, could the DVM be bad?.....I pulled out another meter all is perfect! Seems that Greenlee meter if the battery is low will give all kinds of false readings......Man, do I feel good now! I just couldn't understand how I was creating a couple more...

    How Is This Possible???

    How is this possible?....Here are a few pictures of the just completed solar/12v system in my truck camper.....As you can see, the battery monitor, the solar charge controller and its monitor and the readout on the batteries are all showing 13.3v and 97%SOC. It is night time when these pictures...

    Two batteries to one inverter

    I was just told by a service person at an inverter company that when using two 12V batteries in parallel you should connect the inverter to only one of the batteries, and not 12V+ to one battery and negative to the other......In every system I've installed I've always connected the two batteries...

    4 panels ...Series/Parallel??

    100aH / 12V batteries X 2......Parallel = 200aH @ 12V

    4 panels ...Series/Parallel??

    Looking for advise. I have four EcoWorthy 100w panels and a 40A EPEver solar charge controller feeding two 100aH Lithium batteries. Should I use Series or Parallel or a Series/Parallel configuration on the panels? Please educate me as to why one configuration might be better than the other...

    Thanks! I'd rather not disclose the battery make as the "Cheerio Pissers" will go crazy as to why I shouldn't buy this brand.....:giggle:

    Blue Tooth Battery Fun

    Blue Tooth fun.....I have two, Blue Tooth capable, 12v, 100aH, Lithium batteries in parallel in my travel trailer. One stopped connecting to Blue Tooth on my phone and tablet. I called the manufacturer and they wanted me to send the battery back soi they could decide if it needed to be replaced...

    Two 100aH/24v batteries?????

    Are two 24v, 100aH batteries in parallel the same as four 12v batteries in parallel? IE 400aH?

    Confused..aH at 12v or 24v?????

    Thank You…. But Im considering an All In One s unit that has Solar CC, inverter and battery charger. The only heavy wires will be between the battery and the All In One….from there it will be 120v wiring and a converter from “X” volts (24v?) to 12v for 12v devices in the trailer. Solar panels...

    Confused..aH at 12v or 24v?????

    I currently have two 100 aH 12v batteries in parallel running a 1000w Xantrax 12v inverter in my travel trailer. So my system now is 200aH. Im looking at “ All In One” 3000w, charger / converter and a server rack mount battery system for my next camper. Choices are 12v, 24v, and 48v….I...

    Renogy DC to DC charger...interesting

    Update on my original post here.....I just returned from a two month, 7700 mile cross country trip from Massachusetts to Arizona and back...Great trip BTW!.....I had reason to use the Renogy DC to DC charger a couple times while on the road. This time batteries (Two, 100aH Renogy Lithium in...

    Strange BT Readings???

    All this solar battery stuff is so strange sometimes.....I'm sitting here in the trailer, the heater is running and the fan is blowing. All of a sudden the fan upshifts to a higher speed........Yup, the other battery kicked in and now it is showing amp output and reduced voltage......This stuff...

    Strange BT Readings???

    I have two 100ah/12v Lithium batteries in parallel. Both have BlueTooth reading capability. One battery is showing 100% SOC/13.7v and 0amp draw. The other battery is showing 93.5% SOC/13.2v and 4.99amp draw.......Looks like the first battery BMS shut it down?

    How to lower charge voltage

    POWER MAX....Darn! Why didn't you tell me about this unit before!!! :) This looks like EXACTLY what I need and a direct replacement for the WFCO module. Strange I never stumbled upon it two years ago when I was doing this conversion. THANK YOU!

    How to lower charge voltage

    Yes it does......But that would be a three or four phase charge profile.........I actually removed the LED charger/converter module and replaced it with the Li version.....Maybe I should have just let it be?

    How to lower charge voltage

    Thinking about this a bit more....I'd love to rewire this whole thing with all Victron...But space and money...and time...limit that option. I already have a good Inverter....What I need is a charger / CONVERTER....Charge the batteries and run the trailer on 120V when plugged in. I have a...

    How to lower charge voltage

    Anyway to lower voltage?.....My camper has a WFCO converter/charger. It is set up for Lithium but it outputs 14.6v. I spoke with my Li battery manufacturer and they said not to charge the two 12v/100ah batteries over 14.4v. Is there any way to limit the output of the charger to 14.2? I have 12v...

    Balancing two 100ah/12v Lithium batteries???

    Thank You!....One battery is at 13.85v/100% SOC and the other is at 13.59/90% SOC......before I put them into the trailer should they both be at the same SOC?

    Balancing two 100ah/12v Lithium batteries???

    Folks are suggesting that I should charge both of my 12v/100ah Li batteries to full, and then connect + to + and - to - and let it sit for 24 hours. These batteries will be used in parallel in my travel trailer. Is this accurate or necessary?

    I dont believe there are any issues with the design as it has been working great for two years.

    Two batteries rather than One...

    Why TWO smaller batteries rather than one BIG one......When I recently converted my RV to Li, I had a choice of a single 200ah battery or two 100ah batteries. I chose TWO.....Glad I did. Here I am out in the high desert of New Mexico on a two month cross country trip and one of my batteries are...
