    Can I use this mismatched panel effectively with my current system?

    The current setup on our RV is 4x JJN 100W panels (ground deployed) running in parallel. https://www.amazon.com/gp/product/B09V558GBJ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 Vmp 20.4v Imp 4.91a I have an opportunity to get a Furrion 370w panel for free, and would like to mount it on...

    Our NEW GO-TO LiFePO4 vendor...09.20.21

    Apologies for the necro post, but the last time I was here this thread had three pages and it is now at 47; searching for the info seemed a daunting task at best. What's the general consensus these days on Doncan/Jenny Wu? I see their profile is no longer available here. I ask because I...

    LiFePO4 and auto alternator concerns...

    We've been running our 280aH lithium in parallel with the starter battery and charging all via alternator for four months now, no issues whatsoever. It's great to have charging power on tap on when solar is not an option. It's also wonderful to arrive at our destination with the house...

    another dreaded alternator charge lithium thread

    Just another data point here; been running our DIY EVE 280Ah LFP cells in parallel with starter battery on our E450 class C RV for a little while now and can report the setup is working great. Had a three hour drive last week and was able to monitor via the BMS bluetooth connection. Alternator...

    Our NEW GO-TO LiFePO4 vendor...09.20.21

    Hey all, just wanted to chime in and relay our experience with @Jenny Wu and Docan. I had initially ordered four 304Ah EVE cells for our class C RV while in deep in Michigan's Upper Peninsula (we're full timers.) There was a misunderstanding, but after coming to the realization that they were...

    LiFePO4 and auto alternator concerns...

    A thermocouple on the alternator is a great idea. Love your plan, it's far more comprehensive than my simple house battery shunt/single gauge setup and will allow you to see every step of the process. My plan is to not run the batteries down that far and keep the charge cycle between the knees...

    Our NEW GO-TO LiFePO4 vendor...09.20.21

    Agreed. I just pulled the trigger on four 304Ah cells for our class C Winnebago (delayed two weeks out of Houston because they are out of shipping boxes lol.) Thought about getting eight... but too much battery for our entry level solar system :)

    LiFePO4 and auto alternator concerns...

    @time2roll, yes, all precautions are in place, and I have fulltime monitoring capability. Think I'm gonna throw caution to the wind and go for it. Gonna be a couple weeks before the cells arrive and I can get everything set up. Hope to learn more from you guys during the downtime. Looking...

    LiFePO4 and auto alternator concerns...

    Short time lurker, first time poster... glad I found this thread :) We've got a 2010 Class C on Ford E450 chassis. From what I've been able to determine, alternator is rated at 120-140A and internally regulated by the ECU. Our "beginner" solar infrastructure is in place; 2x100W panels, 40A...
