  • Post in thread: Top Balancing...Do I need to go to 3.650V?

    Ok, last night I ran to HD and got a DC light bulb. It only pulls 8.8W, which is about the best I could find. I also hooked up my air compressor that barely sputters along at 3.5V, but it's something. I turned on the charger and within a few minutes, here is where I am already. It's as if I...
  • Post in thread: Top Balancing...Do I need to go to 3.650V?

    Hello everyone, Thank you all for your insight and help! I decided to go ahead and charge the pack in series until one of the cells hit 3.650 and then switched over to parallel. I took them up to 3.650 and then cut the power until they dropped down to 3.550 or so. Then I reapplied power to...

    Sounds good. These are new, so hopefully that'll take a little variance out. These are 80"x40" and cost $160/ea. So a little over $.05/inch. I'm going to swing by there tomorrow to check things out. I'm not sure how to test the things you mention, but there's YouTube! Hahaha.

    Yes sir
  • Post in thread: RV Energy Audit Results...Seriously?!?!?!

    Thank you grizzzman, that's kinda what I was thinking. Put as much solar on the roof as I'm willing to do so, then get a larger battery bank so when I do have to run the generator, I have more storage for the energy. Then maybe I'll only have to run it for 30-60 minutes once a day.
  • Post in thread: Transfer switch issues after solar install

    Couldn’t sleep, lol! After @time2roll’s comment, I remembered I had shut off the breakers when I was monkeying around with trying to get the battery situation figured out. Sure enough, I had the two 30A breakers off. Everything is working now. Stupid.
  • Post in thread: RV Energy Audit Results...Seriously?!?!?!

    Thanks Will. I'm really enjoying your videos as I try to learn this stuff!
  • Post in thread: Will be testing and providing a full report on Eve 280ah from Dongguan Lightning New Energy Technology

    Hello, I found Hayley on Alibaba and she forwarded me this thread. When did you order your cells? I’ve been caught up in that group buy debacle and paid nearly $2000 back in February. I’m still without cells. ?‍?
  • Post in thread: RV Energy Audit Results...Seriously?!?!?!

    Speaking of thieves, judging by your handle, you’ll understand. I had an Aprilia RSV Mille stolen right out of my garage. It was one of five in Arizona the first year they started importing to the US. Not cool.
  • Post in thread: Top Balancing...Do I need to go to 3.650V?

    Ok, I had them in parallel at 3.615 and all settled overnight disconnected and are reading in the 3.440 range. This was on the first batch, so the second one I'll stop at 3.550. I understand that this is only for the initial top balance. Once I start hooking everything up, then I'll start diving...
  • Post in thread: 280AH vs. 304AH EVE Grade A - Which one?

    I don't trust anyone in this business. That is why I'll be driving to Houston and picking up the batteries in person from the warehouse. I've been waiting since February for cells and finally pulled the plug (no pun intended) and will do this all in person if I can. I will test the voltage of...
  • Post in thread: RV Energy Audit Results...Seriously?!?!?!

    Hello @BlueFox, I am just reading labels. The monitor is a 34" Curved LG. So yeah, it's big. I have the laptops at 2hrs/day since they can run off their batteries. Being Apple, they last most of the day on a single charge. There could be some savings on the brightness levels though. The sounder...
  • Post in thread: Top Balancing...Do I need to go to 3.650V?

    I'm using an Overkill.
  • Post in thread: BMS Needs?

    I think I was wanting to go for the last option, the 2P8S setup. Would this yield a 560ah system if I used 280ah cells?
  • Post in thread: RV Energy Audit Results...Seriously?!?!?!

    Only problem @smoothJoey, we sold our house and live off grid 100%. Not really a problem, but you get what I mean. I just ordered a meter for individual items. In the mean time, I'll research solar panels and layouts.
  • Post in thread: Top Balancing...Do I need to go to 3.650V?

    Good to know! LOL! I did something right. I'll take the readings off my first set and post them here in a minute.
  • Post in thread: LiFePo4 Batteries not charging to capacity

    System - 24v 560Ah total - MPP Lv2424 - 1620W of panels Hello everyone, I just plugged into shore at 50A and my Overkill BMS is showing that the batteries aren’t charging to the full 280Ah/each. Any idea why this would happen? I also noticed that my Delta is way out of whack compared to what...
  • Post in thread: Top Balancing...Do I need to go to 3.650V?

    I got them from Amy Zheng at their Houston warehouse. I was in TX and had such a bad experience here in the group buy, that I drove to their facility so I could inspect them with my own eyes. They look great, no dents, QR intact, etc.
  • Post in thread: RV Energy Audit Results...Seriously?!?!?!

    Yes, we live in the RV and boondock 100% of the time. So we are just using the generator at this time.
  • Post in thread: RV Energy Audit Results...Seriously?!?!?!

    So I made a trip into Phoenix and went to SanTan Solar. Wasn’t really planning on purchasing anything as I feel like I’m still learning. However, I ended up purchasing four 405W Jinko panels. We tested them at the showroom and output looked great. So off to the next component. I have the battery...
  • Post in thread: Circuit Breaker / Fuse between AC In and Inverter?

    Hello everyone, I'm wondering what folks use for a circuit breaker/fuse between the 120VAC In and an MPP LV2424 Inverter/Controller? I can't seem to find a good solution on Amazon for AC, only DC. I wasn't wanting to install an actual circuit breaker panel for one circuit. Also, what amperage...
  • Post in thread: RV Energy Audit Results...Seriously?!?!?!

    @Will Prowse, Just watched your review of the ET Bifacial. What do you think about those on an RV if I could rig up a tilting system that could tilt both directions? Thinking that I could have them tilted towards the morning sun, drop flat at 11am, tilt towards the evening sun at 2pm...approx...

  • Post in thread: RV Energy Audit Results...Seriously?!?!?!

    I just ordered a Kuman meter from Amazon for the individual items in my RV. I think that'll get me close enough. I'll just get as much solar as I feel comfortable with on the roof and spend some money on more battery cells. Hopefully that'll get us close to actual usage. Thank you for looking...
  • Post in thread: 40A MPP LV2424 Input vs. 50A RV Grid Rating

    There is an automatic transfer switch currently to switch between the 50A shore and the generator. Where would the manual switch be placed?
  • Post in thread: Renogy 2000W Inverter and Xantrex PROwatt Xfer Switch

    Hello Everyone, Ran into problems with my Magnum-Dimensions inverter and switch. Just ordered the Renogy 2000w inverter along with a Xantrex auto transfer switch. Anyone have input on either of these items either positive or negative? Just curious about the reliability. This is a temporary fix...
  • Post in thread: Two 8s Overkills?

    Hey everyone, Just fired up my system. I have two 24v 280Ah Eve packs built with Overkill 8s BMS’s attached. So my total system has 16 cells (8s2p) for a 24v 560Ah system. I’m running an MPP Hybrid LV2424. My question is this…how do the two packs work together? It seems like one was pulling...
  • Post in thread: 40A MPP LV2424 Input vs. 50A RV Grid Rating

    I already own the MPP, so I'd prefer to find a solution using what I have. I'm not attempting to run the A/C with the solar. I've understood that I need to be on shore or run the generator if I want A/C. With that being the case, do you think I can accomplish this without the Victron unit?
  • Post in thread: 40A MPP LV2424 Input vs. 50A RV Grid Rating

    I'll keep digging on this site trying to find a solution. Just haven't come upon it yet.
  • Post in thread: Overkill BMS issues…

    Hello, I have two BMS’s that are each hooked up to an 8s lithium bank. Total system is 8s2p for a total of 24v and 560Ah setup. I’m having issues when checking on the state of charge that the software keeps showing 0A and 0%. I open up the settings, change the battery size from 280000mAh to...
  • Post in thread: Top Balancing...Do I need to go to 3.650V?

    Hello All, I am finally putting together my batteries for my full time RV set-up. I am setting this up as an 8S2P system with a total of 16 280AH Eve Cells Using two Overkill BMS's I've charged my first set of eight cells in series with one of the BMS's to 280Ah and the total charge resting is...
  • Post in thread: RV Energy Audit Results...Seriously?!?!?!

    Ok. Being in AZ, is there anything at SanTan Solar you’d recommend? I was looking at those Hyundai’s, but can’t find any reviews. It would be very cost effective to just pick them up locally vs. shipping costs.
  • Post in thread: RV Energy Audit Results...Seriously?!?!?!

    Nice, I was wanting the 381M until this Cyclone 4214 popped up. Wife loved the front living and I still got my 14' garage for a 4 seater side by side. Wow, you have one heck of a build out. With all three A/C's running consistently, do you have any hearing left? LOL!
  • Post in thread: 80A Solenoid on 24V System?

    Anyone have some guidance for me?
  • Post in thread: Circuit Breaker / Fuse between AC In and Inverter?

    It’s the 120 that comes in from shore power, goes through the transfer switch, and hits the MPP.
  • Post in thread: Two 8s Overkills?

    No. Both positives go to a bus bar and likewise with the negatives. They are both discharging at the moment. However, yesterday A-H was discharging 14-15v while I-P was charging by the same amount. So I wasn’t sure what the heck was going on.
  • Post in thread: Two 8s Overkills?

    Yeah, I was thinking that. I’m still trying to get the shore and generator wired into the system via the transfer switch. Problem is that I’m leaving for Bible camp in a few hours and will be gone a week. ?
  • Post in thread: Top Balancing...Do I need to go to 3.650V?

    I've got one on order. Should be delivered tomorrow and I'll pick it up on Sunday.
  • Post in thread: Top Balancing...Do I need to go to 3.650V?

    I made the changes you mentioned. However, I don't see in the settings on where to change the boost/absorption nor the float. I am using the app on an iPhone if that matters.
  • Post in thread: Top Balancing...Do I need to go to 3.650V?

    No, I didn't. I'll do that now. Do I need to use oxguard/noalox? If so, is that found on Amazon or...?
  • Post in thread: Two 8s Overkills?

    Ok. Let me finish pouring my coffee and then I’ll jump in there.
