Hey Gary, these Growatts have two versions of solar charge controllers. One version with lower voltage DC (also less expensive overall). The other version is higher voltage; I believe 250VDC is it's highest rating. Hope this helps 👍.
Need to make one of them total clips were you just plug it into the box and it does itself and do its own charging this Plug and Play even dummies like me can run it total of grit so we can get away from the electric company
I am having issues getting my inverter to power on I have hooked up 240v and flipped the on button nothing happens. I have had my inverter and batteries in storage since 2019. Is there some kind of fuse inside the case that I would need to flip ?
Hi, thanks for reaching out. We're sorry to hear about any issues you're experiencing with your inverter! Please send our Support Team an email at Support@BigBattery.com with some more info on your troubleshooting steps so far and the current issues you're experiencing. One of our reps here can discuss the issue more in-depth and provide a path forward. Thank you!
Hi, thanks for your question. Generally, a precharge resistor is not needed. However, if your battery is continually triggering the BMS' short circuit protection when connected to your inverter, one would be required. This can happen due to some higher output inverters having larger internal capacitors that create the large in-rush of current which triggers the BMS protection, particularly when that high-output inverter is connected to a single battery, especially one that may be undersized for the inverter it's paired with. As long as your inverter is appropriately sized for your battery bank, a precharge resistor shouldn't be needed. If you're currently experiencing issues with your battery and inverter, feel free to reach out to our Support Team at (818) 280-3091 and one of our reps here can diagnose any issues and provide a resolution for you. Thank you!
They are not tied even in pass through mode. The system continues to use the built in auto transformer to provide the output neutral (no input neutral to even connect). This ends up having additional reactive power on the input side of the inverter potentially using more grid power in pass through than expected.
Hi Jasmine, thanks for your suggestion! We have a lot of tutorial and installation content planned so we'll be sure to note this for future videos. Make sure to hit the subscribe button to catch future install videos!
Hi Larry, thanks for reaching out.

Thank you!
I bought this from you guys, and I am still unable to use, I have tried contacting your tech support, only to be sent to growatt, Wish it would have been easier. Anyone that can help a novice?
@@MaxLtd2010 nope, 3 weeks ago I spoke to RC who assured me to be the one to help. By now I can see the battery that was sold to me is obsolete. Also I see the growatt 3k kit is no longer offered on website. To me that means I’m possibly not the only one that could have same issue. Still waiting on assistance. Still no power.
Very nice setup . .. is there a built-in charge controller for solar

When connecting the battery to the inverter, do I have to use a precharge resistor to prevent damage to the inverter?

In passthrough, are inverter's Output neutral and grid's neutral wired together?
They are not tied even in pass through mode. The system continues to use the built in auto transformer to provide the output neutral (no input neutral to even connect). This ends up having additional reactive power on the input side of the inverter potentially using more grid power in pass through than expected.
Could you make a video wiring the inverter to the critical loads panel.

Hello, I'm not seeing solar icon on my screen..I'm also have 0 solar input but I'm getting 145v coming in
