    DIY - Canvas Enclosure

    Thanks guys for the kind words. . . I'm back at my sewing machine for the next few days. Hopefully I can make good progress on finishing things up.

    Sailrite Sewing Machine

    Sure . . . @Jmunk - For occasional work the Sailrite LS machines are OK IMO. Not great, but OK. They are not a needle feed machine, just a walking foot, so top-stitching can be a problem when sewing through multiple layers of fabric. It sort of depends on what Singer model you have. I...

    LiFePO Batteries ???

    Better results today . . . The Inverter charger charged up the LFP's and actually went into Absorption mode . . . :oops: . . . No fault warnings . . . . . Here is the configuration I have at this point . . . . . . . . . Here are the other chargers . . . Solar (EPEver DuoRacer) . . . ...

    LiFePO Batteries ???

    Greetings . . . having survived the Apoc-eclipse of yesterday, I will be away from the boat for a while (probably a good thing at this point). :ROFLMAO: Anyway, I am going to test the Xantrex charging this morning to see if it still produces the fault. The description of the Hi Batt Cut Out...

    DIY - Canvas Enclosure

    Progress Update . . . The sun finally came out today, but I hear that it is going away for a while this afternoon :oops: . Anyway, I got some of the canvas pieces set up for test fitting. . Looks OK. I made it bigger than the template I was using, but actually it is not too big at all, just...

    LiFePO Batteries ???

    A bit frosty this morning . . . . . The batteries were at about 35˚F, so I'm letting things warm up a bit. I did check all of the settings on the Xantrex and made a few changes. . . (1) Disabled Auto-charging, and (2) Set the Hi Batt Cut Out (HBCO) voltage to 15.0v vs. the default of 16.5...

    LiFePO Batteries ???

    For all those following along, here is the wiring change I made to the solar controller so that it would 'see' the starter batteries. Before (did not see the starter batteries) . . After (sees the starter batteries)

    LiFePO Batteries ???

    That's a lot of questions. :LOL: The Xantrex shows the over-voltage warning (Fault #49) The relay shuts of solar charging when the engine is running. (not really needed, but I put it in anyway) I'll see about battery temperature compensation. Not sure if there is an 'off' setting. . ...

    LiFePO Batteries ???

    I've had success with the solar charger . . . even though it has a mind of its own :ROFLMAO: . I got the starter battery issue sorted; just needed to move the FET activation wire over to the solar panel input. Then the controller recognized the starter battery bank. At night the FET's will...

    LiFePO Batteries ???

    Yet another update . . . I switched my attention to the solar charger (EPEver) (the sun has not been out for the past 3 days, so solar charging has been challenging. Anyway, I was able to set the battery type (BATT1) to LFP4. The solar panel voltage is pretty decent even in the clouds. I am...

    LiFePO Batteries ???

    Here is the error message and the explanation from the Troubleshooting Guide. . . This is all fine and dandy, but I cannot find anywhere in the manual that speaks of a 'High Battery Cut Out' setting. I did find a 'Low Battery Cut Out' (LBCO) setting. I am beginning to wonder if the solar...

    LiFePO Batteries ???

    The AGM profile was no better . . . same thing . . . ran for a couple of minutes then the LPF's said overcharge and set the voltage to 12.7. I reset the Xantrex to factory settings and will see if that make any difference.

    LiFePO Batteries ???

    Quick Update . . . The LFP batteries were at 13.3 volts this AM. I turned on AC power and watched the charging. It was at 13.8-14.0 volts for a couple of minutes @ 20 amps in 'Bulk' charging phase. Then the voltage went up to 14.9-15.0 all by itself o_O and the batteries went into protected...

    Surprise My electric car is not charged.

    A word of caution to the group . . . keep the government (and the political commentary that it leads to) out of this discussion, else the thread may be closed. :unsure: Yes, the sea level is rising and the shore line is always moving. What is set in motion will remain so until acted upon by...

    LiFePO Batteries ???

    FWIW - Here is the 'as built' wiring diagram. The purple wires are the lithium-powered positive leads on/from the off-grid panel that I made. I'm seeing the over-charge fault on the Xantrex, which I assume is being magically communicated from the LFP's. When it has the fault, the voltage goes...

    LiFePO Batteries ???

    Thanks guys . . . I'll be taking a fresh look at things in the AM. The fact that the Xantrex unit does not have a lithium setting blows my mind. The stupid ProNautic has one, but it was not a good option (design-wise) to have the ProNautic charge the lithiums. @bruceb58 . . . There is a...

    LiFePO Batteries ???

    I got another over voltage fault . . . so something isn't right. Got to figure out the solar controller stuff and then see where the issue lies.

    LiFePO Batteries ???

    Still waiting for the sun to come out so I can configure/test the solar controller. I think the sun might shine here on Monday. :rolleyes: In other news, I got a 'over voltage' warning on the LFP4 batteries . . . not sure why. They went into "don't do that again" mode for a while, but they...

    LiFePO Batteries ???

    I'm not sure why the chargers have all of these adjustable parameters ??? :unsure: Both the ProNautic and the Xantrex just charge at what ever voltage they want regardless of the settings. :rolleyes:

    LiFePO Batteries ???

    I found the 'Advanced Settings' menu . . . no idea how I did that and probably couldn't do it again if I needed to . . . :ROFLMAO: I adjusted the 'custom' charging parameters as shown below. My understanding is that 'equalization' via the power supply is not something you want enabled. Not...
