    Very smart idea of the combiner box, Very neat job! I want see your entire setup. You should come visit my place… sometime.
    Still got the 12-K?

    Interesting build. My solar system has SOK batteries (the ones without the display). I purchased an EEL DYI 48V battery box and want to integrate this into my system. The SOKs are 48V set in parallel. What would be the best way to incorporate the EEL battery box. Thanks for your time. John

      @@johnrutledge1877 The Lynx 1000DC distribution bar should be good. Each battery would be fused as well through the bus as another layer of protection. It is a modular bus bar. So yes the EEL kit battery should parallel in just fine. Each battery will share the loads across the device. It’s a quality unit.

    So you need about 100v solar input or it won't work and charge? Would I be ok with 2 48v panels?

    • @THEOFFGRIDMOUNTAINHOMESTEAD
      @THEOFFGRIDMOUNTAINHOMESTEAD  8 днів тому

      60-145VOC on the built in MPPT. I have connected a 400W array to this inverter several times to check functionality of the solar charge function. 88VOC (4-100W panels) the charger likes to track this array at 60-65V. Delivering 340W which is exactly the same I get from the array on a MidNite solar stand alone controller. So the inverter tracks well from initial testing.
      The drawback of the inverter is idle consumption vs a stand alone charge controller. 50W idle consumption.

    So Bus Bars can combine various Battery Banks of 280 amp hour and 100 amp hour Batteries and a 24 Volt Battery Banks to Just 1 Battery Combiner Box ?

    • @THEOFFGRIDMOUNTAINHOMESTEAD
      @THEOFFGRIDMOUNTAINHOMESTEAD  6 днів тому

      Each battery should have its own overcurrent device when shared or connected as a common battery bank. The larger the battery bank and lower the current on each battery helps equalize out the draw between various Ah capacities. One 280 and one 100Ah would show a disparity when running them hard. Several 280s and several 100s together will tend to current share better and also tend to reach 0 or 100% SOC at almost the same time.

    Would you recommend this setup for a mobile pet grooming station??

    • @THEOFFGRIDMOUNTAINHOMESTEAD
      @THEOFFGRIDMOUNTAINHOMESTEAD  6 днів тому +2

      Might be better to use a 12V setup since you would have an existing 12V charging source on a van/box truck? Plenty of 12V stuff catered to RV folks that would make it easy. But 48V is also viable there are commercially available 12V to 48V charging options that utilize alternators as well. Pick your system size and cost compare. 12V will of course have much larger wire. But other components tend to be lower priced. Some of the new 3000W 12V inverters can hit 90% efficient which is good. This 48V is averaging 94-95% efficient battery to AC conversion.

      @ thank you for your recommendation. It’ll be for a ford transit van that I’m looking to converting into a mobile pet grooming business. I was thinking generator but I think it’ll be a bad idea considering the fumes so I’m looking into lithium ion batteries with inverter to power, vacuum, light, outlets, blower, air conditioning and possibly cameras. I just haven’t made a final decision on what could be the best possible option.

      @@Sp1d3r-h3m There are 12V rooftop AC units for sub $1K that are fairly efficient. No conversion losses DC to AC etc.
      My RV has a 3000W 12V Inverter\charger. It runs the factory 120volt Air Conditioner and Microwave at the same time with a little bit of room to spare. The built in charger can recharge up to 100A back to the batteries on shore power. This type could help you recharge batteries overnight at home before work the next day.

    I tried adding up the price of all those components and why not just go with an all in one eg EG4 6000xp for almost the same price? You'd have everything built in one without the complexity of wiring a pv combiner box, pv disconect, built in breakes, ability to do 240v and almost double the output at 6000w. Just seems like this is significantly more labor, time and complexity to *maybe* save $100-$200

      I don’t have a PV combiner. I spent 30 for the PV disconnect (breaker) and box. Correct an inverter breaker is included with EG4, I had to add for this one.
      Regardless of inverter used a DC battery combiner of some type with individual OCPD would be needed when mixing different brands of LiFePO4 unless one went all server racks of the same brand. Common bus bars still help with server racks and many rack cabinets have them to help with equal charge/discharge on each individual rack battery
