  1. Another great video, I would like to continue building on my portable setup i e. "Kisae DC to DC charger setup". Can you suggest a Pure Sine Wave Inverter to go with my portable setup? In addition since this would be my first time setting up an inverter. Would that Resistor in this video really suppress any sparks that could occur? I have the DC HUB already as part of my portable setup. I would like to have a little AC power if I happen to need it in an emergency. Any help would be greatly appreciated.

  2. Great video! I just recently found your channel and have really enjoyed your clear and concise presentation. I am really considering this sungold inverter. Quick question- how big of a battery bank can this take (e.g how many amp hours)? Thanks!

  3. Is it possible to build this inside a big tool box? I just sold my small power station because i want something bigger for emergency or my job ( drywall construction) and building this on a tool box would be easier for me to carry

  4. I was wondering how you wired your transfer switch. The inverter output is 120V AC. So you can't wire with 120/240 split phase. Did you just use a jumper off the hot to power both bus bars with 120V? Seems like that is the only way be able to use all six breakers. Thanks.

  5. OR Get a porpane generator with a transfer switch. Don't store a degrading power transfer switch. Battery solutions for backups are such a waste of money any battery backup solution is a waste of money for houses.

  6. The Danfoss BD50f compressor, for refridgeration, can operate in any power source, it requires 109 watts to operate. You need to purchase the Power Module for your voltage needs, 12/24v, 115v, or 220v.
    The Power Modules contain an inverter, transforming the input voltage to the requirements of the BD50f.
    If you have a 115v refridgerator with a BD50f compressor, you can swap Power Modules to the 12v version and run the refridgerator directly from batteries without an inverter. Therefore, more efficient battery usage.

  7. Cool idea, however your fuse amp rating needs to be smaller then the amp rating of the cable. Also solder on cable going under a screw isn't good practice. But well done and good work.

  8. I bought the 24v kit. The issue I have run into is delayed shipping. They didn't inform me most of the kit is in background. The other issue I ran into is I did manage to get it put together and the batteries won't charge. Tech support is really slow to respond.

  9. I'm just getting started in my solar journey and I am looking for informative videos. I like your presentation style. It moves fast, covers the subject well. I appreciate the matter of fact approach. You speak clearly without stammering or pauses. I subscribed and liked. Well done.

  10. I am planning to do a similar 24V home backup setup using a transfer switch and possibly the SunGoldPower 3000W Charger Inverter. I have been reviewing videos to understand how to setup a home backup system and I am getting close. I have two questions.

    The PV input voltage to the charger inverter states that the operating voltage should be between 120-400V. I understand that the VOC of the PV array should not exceed the maximum PV open circuit voltage of 450V but what if the PV array voltage (VOC or Vmp?) is less than 120V. Does the unit stop charging with solar? Do the PV panels I select, connected in series, need to have their Vmp greater than 120V?

    I am planning a battery bank of four 12V 100ah batteries connected in a series parallel configuration. I have seen some videos where the battery bank is attached to bus bars and then to the charger inverter. Is adding a second battery bank (four 12V 100ah batteries connected in a series parallel configuration) to the bus bars the same as connecting the two battery banks in parallel? When adding the battery banks in parallel (no bus bars) I assume the cable size from the battery bank to the charger inverter needs to increase since all the amps are flowing through one set of cables instead of two separate sets when using bus bars.

    Thank you for your response.

  11. I can't afford this type of setup at the moment & really don't know that I would if I could,… For now, I have a a Chinese 2300/1800 watt Inverter Generator for under $400 that I flushed & prepped well before starting & I installed a 30 amp Generator Inlet Box to the outside wall of my Kitchen, ran a one foot 12 gauge wire to a 20 amp double outlet inside the house so that I can run my chest freezer, fridge/freezer, light, fan, TV , Internet Gateway & Pellet Stove if the power goes out and this setup including the generator cable cost me less than $100 🙂
    Would it be nice to run 12 hours or so Silently then use a generator to recharge if needed ? Yeah, sure but the cost is huge for occasional use.

  12. Great video, I just made a video with my slightly upgraded setup, still 12V… i want to go 48V soon. your video helped explain some of the aspects of it. thanks!

  13. There was no comment about the transfer switch wiring, normally they are wired for 240 split phase, but your invertor was 125V…I know the teansfer switch can be wirred as you want, but I did not hear that mentioned.

  14. I happened to be watching while on Bluetooth to my home theater receiver with Klipsch dual 12 sub.
    When you connected the battery to the inverter, the floor shook🎉 😂

  15. We're planning on making one of these for our new home.
    Do we need solar to charge this, or can we just use the electricity coming in from the power company?
    How many batteries can we connect to it so we have longer use?
    Also, can we just power our refrigerator, freezer, and lights with this?
    Thank you for the video!

  16. Oh, one more thing…I create insulated sleeves with heat shrink tubing. I tape off one end with electrical tape and then I slip one each over the pos and the neg lug. I use a tubing diameter that is snug enough that it will not fall off.

  17. I built a system very similar to yours but I used a cart made of composite material that is non-conductive. I enclosed the battery storage shelves with chalkboard material bought at Home Depot for under $10 each. I cut them to cover the sides and back of the open areas pf the cart. I secured them to the cart with strong Velcro. This will prevent items getting into the battery area.
    I do not have insulated tools, but I do cover the tools I am working with in heat shrink tubing.

  18. love the cart setup. an alternative to the resistor is to put a filament light bulb in series on the positive lead when connecting the battery. also there are a lot of 240vac output ups solar inverter chargers. to use one of those you'll have to add a split phase or center tap transformer, but you can get from the ac output lower amperage while delivering the same amount of power.

  19. I really need to upgrade my system to LiFePO4 batteries.
    I've got a similar setup attached to 2 160W solar panels. Two 115A/h AGMs, a controller/regulator, and a 3000W Pure Sine wave inverter. I feel like it needs more battery capacity because I can lose 10% of my charge in an hour or two in full sun on the two parallel-connected batteries when running a computer, TV, stereo system, a 75 litre dual zone twin-lid camp fridge, a phone charger, and some LED strip lights. I'm wondering if I've set up an inefficient system. Both panels are connected in parallel as well. Maybe I'm expecting too much from the setup, I dunno. I can run the fridge by itself overnight after an hour or two of using the computer system setup, and it only drops to 48/50% . I need to rethink my computer setup though. It's a desktop using a 100cm Tv as a monitor, and a Sony stereo system for speakers. A lot of power just to watch YouTube and catch up with news and social media.
    Good thing I have a ULP genset as a backup I guess.

  20. I own two Bluetti AC200P's, Echoflow Pro, and an off-brand 2000 watt solar generator plus I have 2820 watts of solar input. My solar generators are usually fully charge by around 12:30 pm. I live in Golden Valley, AZ with around 300 full solar days per year. I have excess solar charging capacity on most days. I like to tinker around with stuff. So, this gives me some ideas for my next project. Thanks for the video!
