    Magnum questions

    The moved the plant? Dang! And they could update the remote huh... Yoda I want the cutoff at 50v. sorry, I typoed the "59v = 10%" there 49 is 10% so I want 50v to be the low cutoff. A question Yoda, do you have to use a separate controller for different facing panels? I have only ever done...

    Magnum questions

    I have a system that has been awesome to date, had it for almost 8 years now. I have an older 4448 with a slightly newer ME-ART I upgraded to some used lithium batteries that are higher voltage then the inverter wants to cutoff at. These are at 10% at 59 volts, 90% at 59 volts. I want to set the...

    No longer deal with ever again AliExpress

    Contact your bank (credit unions are even better!) open a dispute with them, give them the 'order canceled by seller' and they will promptly refund your money and do a charge back to paypal... I have had to do this multiple times when ordering things from China, half the time I get what I...

    More DALY smart BMS issues

    Do you mean your BMS stopped working? Or the voltage went wrong? OR? Daly has to be installed in a specific order I found out... irritating IMHO... I looked up the Overkill BMS, looks identical to the Daly?

    More DALY smart BMS issues

    YEP, I am having the same issue, of course AFTER I post my problem I find yours LOL. I will be watching your post if ANYONE has any information, On the phone I can get some of the third parties to at least connect to the Bluetooth, but it reads like "23%" when the batteries are at 57.2v (Li-Ion...

    First question! Daly BMS unable to communicate with PC!

    Been looking around and can't find this answer! I tried interfacing via bluetooth, Sinowealth just sits there "SBS Task Scanning" doesn't move. After about 45 minutes program locks up and locks up the COM port too! I tried it with the USB UART and the same problem... UART is connected to Com 6...

    Brown bear destroyed our yurt powered by Yeti 3000, so I'm designing solar for a cabin & a bit lost

    The angle and direction of the panels is what I mean by winter panels. My panels in WA are adjustable but I have to do it manually every 3-4 months if I want to and it isn't... easy. I understand what you are saying, you aren't at the cabin for sometimes several days or longer? Ya that would...

    Why don't we get more from 800 watts of solar panels?

    8 panels would be either a 2s4p or 4s2p. It sounds like you are doing a 2s4p system. 4s means 4 panels in (S)eries 4p means 4 (P)arallel strings(or panels). So 2s4p would be 2 panels in series and then 4 parallel strings of those 2 panels so 2*4 or 8 panels. Below is a 2s4p configuration of...

    Brown bear destroyed our yurt powered by Yeti 3000, so I'm designing solar for a cabin & a bit lost

    Sorry to hear about the bear. Are you putting these batteries outside? I keep my batteries inside, WA state, not nearly as cold as Alaska, but still close to 0F outside through winter, inside never below 50, don't even need to worry about the freezing. If you are keeping them inside the cabin...

    Am I crazy to put a 1760W solar system on my RV?

    If you can fit those panels on your roof AND have the support, GO FOR IT! I have a 2600W setup with my RV but it is a separate system, ground mount. I have seen up to 4KW systems where the panels retract and extend like wings on either side and some where they have mounted them over every sq...

    Need expert review on my First System Design for my RV

    GC2 is a 450 AH battery, 6v right? So 4 would be 12v, 900AH or 24v 450 AH, and about 11KWH total @ 20% 2 KWH useable under best practices, but these are deep cycle golf cart batteries so they are specifically designed to be able to take more of a beating and you can probably eak out double that...

    RV has two types of led acid...whats the ah for my CC?

    As I said after re-reading my original post for the 5th time, I COULD have worded the 'not for very long' better and I would edit it if I was allowed at that point. While it is true some things can be harder or softer said, there is always the possibility that some one will walk away with the...

    Need expert review on my First System Design for my RV

    If cost wasn't an issue, I would say build a frame around the rig. Attach it to the underframe of the vehicle and run just bars across the roof, only need to bolt/glue it down in maybe 4 spots on the roof and the panels will be above all the OEM components and most of the weight won't be sitting...

    RV has two types of led acid...whats the ah for my CC?

    this... this is what I am talking about. I specifically said, MULTIPLE times that chargers charge to the VOLTAGE. When you have say 4 batteries in parallel of different capacities you don't get to charge them all the same, you get a voltage reading across them that reads 14.4v but when allowed...
