    I was looking at one of those solar charge controllers but this is the first review of one that I have come across.

      Definitely a great item for folks with 24V and up systems! Good controller to utilize spare/oddball panels and get some charge from them! Appreciate you! 👍

    Question. When charging a battery you should use a pure sine wave inverter to protect the battery. What type of current does it make?

    • @THEOFFGRIDMOUNTAINHOMESTEAD
      @THEOFFGRIDMOUNTAINHOMESTEAD  6 месяцев назад

      Charging as in using an inverter to power up a 120v to 12v switch mode or dc power supply to the battery?
      If using a switch mode charger, they aren’t too picky about incoming voltage on the ac side. Some charger models have better dc ripple smoothing capacitors/rectifiers etc.
      Iota Engineering has bulletproof battery chargers I can recommend them if looking for clean low ripple DC outputs. Very tolerant of dirty/fluctuating AC side power.

      Thanks for bringing this to my attention! I checked the link and indeed the Elejoy brand appears to have been renamed or sold? The model number is the same on the linked controller and specs match. I’ll look through and see if I can find out if Elejoy still offers this model under their page. I will update the link as soon as I can verify. Thank you again!

    I want to charge 72 volt electric scooter with this is it possible.
    My ac wall charger charging ev battery at 12 amps.
    My full charge battery voltage around 77 - 78 volt dc.

    • @THEOFFGRIDMOUNTAINHOMESTEAD
      @THEOFFGRIDMOUNTAINHOMESTEAD  6 месяцев назад

      The charger can go up to 85VDC!
      This unit is cable of 400W sound like your wall charger is 900-1000W
      Solar energy is free though after you buy the hardware!

    Hi good morning can it work with a wind turbine

    • @THEOFFGRIDMOUNTAINHOMESTEAD
      @THEOFFGRIDMOUNTAINHOMESTEAD  8 месяцев назад

      I’ve not tested on a turbine. This would not replace the rectifier on a turbine.
      Unsure if the choppy DC out of the bridge rectifier would upset this unit. 17V minimum input on this boost controller. Sorry I can’t help more.

    Could you use the battery pack while you were charging it? Or is that determined by the specific battery pack?

    • @THEOFFGRIDMOUNTAINHOMESTEAD
      @THEOFFGRIDMOUNTAINHOMESTEAD  9 месяцев назад +2

      Yes you can pull from the battery while charging or if battery is full the boost charger will maintain the pack up to it’s rated power same as any other charger! Hope this helps!

      @@THEOFFGRIDMOUNTAINHOMESTEAD that’s great news thank you so much! I am trying to set up a solar charging station for my boat trolling motor battery as no power where boat is at. It’s a 36v 60Ah LiFePo battery. Want to keep the setup low key so found a compact 12v 50w panel with the DIY MPPT charger on Amazon…it is the 400W one but that should be ok as it is the only limit for the wattage correct?

    • @THEOFFGRIDMOUNTAINHOMESTEAD

      You are correct, 400w is max input, you’ll be fine!

      @@THEOFFGRIDMOUNTAINHOMESTEAD thanks for the reply!!! I subscribed to your channel as I want to do more solar stuff so thanks for all the info! One last question if you don’t mind. With the solar panel and boost controller, I want to keep them close together and run cables from the controller to my battery. Should I install a 15 amp inline fuse between the controller and battery, the run will be about 8-10 ft so I am thinking 10 or 12 gauge wire would be sufficient? And lastly is it ok to use the alligator style clamps on the battery or should it be a solid connection with a disconnect?

    • @THEOFFGRIDMOUNTAINHOMESTEAD
      @THEOFFGRIDMOUNTAINHOMESTEAD  8 месяцев назад +2

      I always recommend using proper OCPD. As for wire size, bigger is better with DC power. The small 50W panel should be capable of only 2 to 3A under perfect conditions. Connecting to battery is your choice. If left unattended a permanent connection is usually recommended. Hope this helps!

      Recently I purchased Victron's 100/20 mppt controller. However, I have not purchased a battery nor the solar panels.
      * That said, my plan is to go with a single 48/100ah battery and a single 300 watt solar panel.
      * The build is for a stealth bug-out F-150.
      * I desire the smallest panels with the largest battery bank possible.
      So I ask, if this boost charger is compatible with the use of a panel that's 200w or 300w?

      @ This boost controller will supply 400W output. Your input voltage has to be 10% less than charge voltage. It current limits on the output side. I have one on my golf cart and use 24V LiFePO4 batteries to charge 36V LiFePO4 golf cart battery. It delivers 10A @ 40.0V and 9.1A @ 43.8V at top of charge, this is 400W on the nose!
