    Your advice has been taken to heart and followed. You can see that in the was that the rack is now wired. Thank you for all you have contributed to my effort to make this off grid work will. Only thing I can say is that the engineers of the the NOCO battery charger are most likely smarter...

    Sorry about all the words. Short and sweet: Your Solar charge controller driven by PV panels will charge your batteries when the sun is out and the batteries need charging. That charge controller is specifically made for your battery bank. Photon Sorcerer Your Solar charge controller(s) will...

    Yes, 4 groups, of 2 in series, with the groups wired in parallel. The 4 red cables in the drawing that come to an apex and then connect to the system are now 24", all equal in length. The orange are also 24". There still could be unequal charging, in that, current will find the path of least...

    I have even heard from a very knowledgeable person, on this forum, that has tested the use of a grid powered DC supply that has voltage and current characteristics that would emulate PV panels and also meet the input requirements of an MPPT Charge controller. The DC charge power supply would...

    No, the 1100 watt microwave was turned on for 3 minutes when there was NO SUN. :) Testing to see what a load would do to the bank. Also needed coffee to warm up a bit. There is a cold front coming in and snow is on the way again. That is why I wanted to get everything buttoned up so...

    Yeah, the NOCO is a professional computerized charger that senses the type of battery, the voltage, and tailors the charging rate for the battery. 25a at 24v is the max. I don't think that it will harm my battery bank of 8 100Ah Deep Cycle RV batteries wired in 2s4p. The 3 charge controllers...

    Sorry, if I were not living on SS and had a deep pocket of cash to spend, I might have money and time for hobbies. I think men should retire in their 20s when they have the money and strength to do hobbies, and then start working when they are about 30. Then, we could just work till be drop...

    Thursday Morning update: * One of the batteries read 11.7v this morning after sitting all night not connected to anything. THE CULPRIT! * I put it on the charger (NOCO GeniusPro50) for 2 hr. The battery read 13.7. I will let it sit and check it again in a bit.

    It would appear that you are trying to find where the leak of 300mils is going. The inverter is not connected to the system and was not connected all night during the test. I think the thing that I was trying to present was that even with the inverter disconnected from the system, there is...

    11:30am PDT update with measurements and thoughts.... It is a mostly cloudy day. Chargers do what they can with what they have. It got really dark with the heavy clouds and the charge current on the system went to 300mils. When outside, I checked the displays on each CC. The readings are as...

    I am not convinced that the drain on the batteries is a purely resistive load, which a battery bank resistance would be. What I am seeing in the graph... before the sun came out is a steady current, but a varying voltage. The voltage drop over time was not a straight line. In fact it had a...

    That's a good word. When the weather improves. I am hoping for that. with the heavy rain, the snow on the ground is finally gone. It has been deep for about 7 weeks. Maybe I can put the snowblower to bed for the season!

    as an update for those looking at the remote VRM, I turned off the only thing drawing current from the batteries. That was the Inverter. I turned it off at 4:28pm PDT. You can see a little glitch to the positive there. It is now 5:18pm PDT and as you can see, only about 700-800 mils of solar...

    Yes, I know. As in a previous post i mentioned that this is what I had on hand to get the system up and running before winter. I didn't make it. Actually, it ended being between snow storms. The electronics cabinet is outside, 100ft out in the yard. It only houses that equipment and there...

    As seen in this screen shot, the voltage displayed could be determined as a rising voltage within the BULK charge mode. It is also within the range of the FLOAT voltage range. Bulk is pushing regulated current toward the Absorb voltage level. But, since the Consumed Ah is not zero, I have to...

    The capacity is 100% at the time that I disconnect the solar from the house each day. That is what the 10 120v circuits in the house use in that 8hr time period. when I know that it will be a strong sunny day, I turn it on early, maybe an hour or 2 before the sun is on the panels, knowing that...

    so that you can see where any possible leaks are in the system, the system is not powering the house. The only thing that is now on is the Inverter. I even went outside and disconnected the AP from the inverter and plugged that into the house via an extension cord. So, there are 3 things...

    Each of the 8 batteries (Exide Brand) wired (2s4p for 24v system) are 100Ah Deep Cycle 12v RV batteries. Half of them are 1.5years old. The other half are 1yr old. (I had the capacity to charge more batteries so I bought more.) They were purchased new locally. They are sealed maintenance free...

    Yes, the bus bars are neutral bus bars from a load center. It is what I had at the time to make it all work, going into winter. They will be replaced in time and when money permits. I realize that 2-3k is a chunk of change to spend on solar. Solar is NOT a viable solution in NW Oregon...

    Thanks for the information on the solar setup. much of that data on charging and usage is "Polluted". Ha Ha. When the battery level gets too low I have been putting my battery charger (Grid Powered) on the system so the batteries will not be ruined by discharging too deep. I am using the...

    Well your avatar says you're a solar saucer So you might be able to find out what that looks like in that picture period obviously that big cable has braided wire and it's too big to go into that bus period so the braids were split into two braids and put into two slots of the bus.
