  • Post in thread: Neutral ground bond totally off grid w generator and reliable inverter

    What other details would you like? When doing the continuity test on the generator 30a plug, I did not know which was hot and which was neutral, so I put the black probe in ground, then put the red probe in both of the other spots, and got continuity on both. It makes sense that I did not...
  • Post in thread: 2x 12v 100ah in series different voltages

    I disconnected everything and using a thinner gauge wire, I got them all to 13.48, and connected them all in parallel and let sit for 30 minutes. They all where at 13.48v, so I disconnected everything again, and wired them in 2s2p. Outside left is + and outside right is -. Hooked it back up to...
  • Post in thread: 3.2 volt packs arrived with low voltage

    That is what I was thinking. Even if they take a charge, they will likely never have the capacity that they should.
  • Post in thread: 3.2 volt packs arrived with low voltage

    They where all still in the boxes that they shipped in. Two of the orders, were in my RV, and two orders where in my enclosed trailer. It has been over 90 degrees where I live, but my enclosed trailer has decent ventilation, and is usually cooler inside than out. My RV has been plugged in and...
  • Post in thread: Low bat voltage conundrum

    Awesome! Thanks for your help, crisis avoided. I just remembered I have another option of a 10 amp variable dc power supply, that I used when I built the batteries. I might set it to 25-26 volts and 9 or so amps, and see if that wakes up the bms. I think it should. If not, I can move to the rc...
  • Post in thread: 3.2 volt packs arrived with low voltage

    No qr code, or manufacture date. They are 3.2v 100ah packs of 32640 cells.
  • Post in thread: Show me your battery bank pics with battery hookup 100ah

    I guess I was looking for, more specifically, battery banks that have 2 or more of the 100ah packs from battery hookup.
  • Post in thread: Over paneling

    Right, I don't want to mix and match. I have two other charge controllers, that I can use the 100w panels on. I am basically setting up different outbuildings on a small farm with their own solar setups. So, in the end, I will have 5 or 6 independent solar setups.
  • Post in thread: Neutral ground bond totally off grid w generator and reliable inverter

    Awesome! Thanks for the info! I will check out my inverter and see if I need to swap the red and black cables. By disconnecting those ground wires on your white inverter, you have disconnected the neutral ground connection at the inverter, so that you can bond them at the breaker box, correct...
  • Post in thread: Mpp lv2424 auto start generator

    I have an mpp solar hv2424, and a Westinghouse igen4500df generator. I remember seeing somewhere that you can wire the lv2424 to start a generator, but I can't find it now. On the lv2424 there is the plug marked nc c no, and that would be the relay to tell the generator to start once battery...
  • Post in thread: Aims 12/24v charger green sticker stating 12v only

    Exactly. Yes it was ebay. eBay and that other site named after a river in South America where the only places that had it available. I am starting to think they had a bad run, that will not charge 24v batteries, and that is why there are none available from reputable sites.
  • Post in thread: 2x 12v 100ah in series different voltages

    The sun is down now, so no power going in, and now all 4 batteries show 13.2v. Was there nothing wrong to begin with, and only showing higher voltage on the outside two batteries because they are the ones connected to the scc?
  • Post in thread: Milk crate solar generator questions

    Hello all. My first post here. I am wanting to build a solar generator based on Will's milk crate 2.0. Would it be okay to run three of these 12v 20ah batteries in parallel, instead of the one 12v 50ah battery in the video...
  • Post in thread: 3.2 volt packs arrived with low voltage

    So, the place that I ordered them from should replace them, correct?
  • Post in thread: Low bat voltage conundrum

    I have a situation that I am unsure how to resolve. I have 2 mpp solar lv2424 all in one charge controller, inverters, and a victron 75/10 charge controller, all connected through buss bars to 3 24v 100ah lifepo4 batteries. This setup has been up and running for almost a year. Now, none of the...

  • Post in thread: Reliable 24v 3000 watt inverter fans running

    I just received a reliable brand 24v 3000 watt inverter, and the fans are constantly turning on and off. On for 26 seconds, off for 10 seconds and repeats that. My current load is a midea u ac, that is pulling less than 600 watts, and a mini fridge that pulls 100 watts, so ~700 watt load on a...
  • Post in thread: 3.2 volt packs arrived with low voltage

    I did not. In hindsight, I should have.
  • Post in thread: Low bat voltage conundrum

    I have some extra panels that I could rig something like that up with. I have some 100 watt panels that have 22.6 open circuit voltage, and I have some 230 watt panels that are 37 open circuit voltage. Or, I just remembered I have a couple rc car/truck chargers. Maybe I could set one up to...
  • Post in thread: Ballance or top charge first

    I bought two of these packages from battery hookup to make a 24v 100ah 4s2p battery. Should I hook all of the packs up in parallel to let them ballance for a couple days, or should I top charge them? I have seen Will use an adjustable dc power supply to top charge, but I don't have one. Should I...
  • Post in thread: Ballance or top charge first

    Oops, I meant 4p2s to make 24v 100ah.
  • Post in thread: 3.2 volt packs arrived with low voltage

    I ordered a bunch of 3.2v cells. I ordered them at different times, as I could afford them. Now I am ready to assemble them in 24 volt batteries, so I put a voltage meter on them, before I top balance them. Below are the voltage readings. .009 .035 .046 .233 .259 1.463 2.033 2.538 2.656 2.938...
  • Post in thread: 3.2 volt packs arrived with low voltage

    These are not prismatic cells. No qr code. Here is a pic from when I was top balancing some of the good ones.
  • Post in thread: 2x 12v 100ah in series different voltages

    I have 4x 12v 100ah batteries in 2s2p for 24v. Today my inverter set off an alert, so I checked the battery voltages, and putting a volt meter on each battery, the voltage is different. On both of the 2s batteries that make the 24v one is 14.1 and the other is 13.3. How is that even possible...
  • Post in thread: 2x 12v 100ah in series different voltages

  • Post in thread: Mazava/powmr ha02 equalizer questions

    I have read and seen in videos, Will included say that there can be problems with over three batteries in parallel.
  • Post in thread: 2x 12v 100ah in series different voltages

    I may try that. Yes, there was power coming in from the scc and going out through the inverter when testing the voltage.
  • Post in thread: Lv2424 (green box) fault code 07

    I have an lv2424 with 2) 24v 100ah batteries in parallel. 9 230 watt solar panels wired in 3s3p. Each solar panel has a ocv of 37, so that puts it at 111 ocv, which is under the max voltage of the lv2424. I also have a 4550 watt inverter generator, that I run to the ac input on the lv2424, and...
  • Post in thread: Over paneling

    I have an mpp brand 1012lv-ms. It has a max voltage of 102, and max watts of 500. I have watched many of Will's videos, including the one in the beginners resources link on this page, where he mentions over paneling, but I am not sure how much I can go over the rated max watts. I found some...
  • Post in thread: Mpp 1012lv display voltage

    How so? Disconnecting one of the pv cables made the screen show the correct battery voltage, and voltage from the terminal on the mpp was within .02 volts of the voltage on the battery terminal. Sounds to me that the discrepancy is in the mpp unit when it is getting power from pv, the screen...
