Thanks for this go through step-by-step video. I have problems understanding point back. I have different 24v model but more or less uses the same info. I understand that a 24v lithium battery has to reach a point when it must switch to utility. But have no idea what that is. In my manual it says "low cut off battery voltage" but I think this is not related to SBU but rather the lowest voltage that the battery can drop before damaging the battery. (I could be wrong) In my manual it also references to "Setting voltage point back to utility when selecting SBU. I think this is your device's option 12 starting @ 9:04 timeframe on the video, then you go onto 13 setting the point back to the battery when the battery has been recharged to this point.
So I believe what you are saying is that there is a point that the battery stops powering the loads (because the voltage has dropped too far) so the unit switch from battery to utility. Then when the batteries have recharged to a cert point, the utility switches back to using battery.
Please help:
I have a growatt 3000 and it doesn’t recognize my PV input at all.
My panels are in series. 8X370 watt panels. I have a pv shut off switch hooked up. Any thoughts?
Hi Brandon. Thank you for watching and for your support. It is really hard to say based on the information that I have. I personally would disconnect the pv shut off switch and run it directly just to problem solve and see if maybe the switch has issues. I hope this helps in some small way. Thanks. Please consider subscribing if you found the content useful.
My guess is you are way over voltage running those in series, you will be lucky if you did not cook the unit. Im guessing depending on your version you can only run 3 panels in series in two sets and then paralell for 6 panels my 3000 growatt has a 145 max volt pv input, the newer version can take 250v so maybe 4 of yours in series and two sets of those in paralell
My shore power is just a 15amp extension cord, so I'm assuming that my setting 11 should also be 15amps. Is that correct?
Yes, that is correct. You could play with it a bit if you wanted to. You could set it at like 18 amps and see if your wires get warm, if not you should be fine. But its probably safer at 15 amps. I have ran my 15 amp at 20 amps with no issues. Thank you for watching and for your support. Please consider subscribing if you found the content useful. It really helps the channel grow. Thanks.
Not sure this is 24v amps. So 15 amps at 120 is about 60 amps.
Great video. With only a generator connected to 48 v Growatt, unable to charge lithium battery. Program item 12 is set at maximum, 51.2v. Battery voltage is 52.6v. SOC is 55%. Could this be the reason I’m unable to charge battery?
Great video. Thanks.
Hello, I have my growatt 3000 set to SOL when batterys get up to full charge voltage, it disconnects solar and runs on batterys until voltage drops and then brings back solar. I was thinking if batterys were full the solar would run the loads? and advice? Thank you.
Greetings. excellent video. I have that same inverter totally off grid. when lithium batteries are fully charged. the solar panels are disconnected, leaving the batteries supplying all the consumption of the house. The solar panels don't reconnect until the battery reaches its cutoff voltage (24v), usually when the sun is gone, so I'm left in the dark at night. any suggestion?
Thanks for the information. Just a quick question, does this inverter have a constantly noise when it's on? Thank you 👍
Hi. Thank you for watching and for your support. To your question, it has a slight buzzing noise, but hardly noticeable. Not loud at all. I have my inverter running 24 hours a day and do not hear anything more. Just when you turn it on, you will hear it turn on. Hope that helps.

Thanks for the video
I have 60 volts from ground to neutral. Is there a way to change that in setting 28?
when the batteries are topped off does the excess power go right to your home grid to reduce how much you are getting from the Utility grid?? I have 2 systems, 1 is a 12v battery off grid system powering my gym, light, heat, outlets. 710AH battery bank with 1kw of panels. I use a SkyMax 440 Charge Controller for Wind, Solar, and Hydro on this, so I can change the batteries to 12v/24v/48v. Then I have a 2kw gridtie inverter system going into my home. I would like to combine all the panels going to the batteries but still have the extra going into the house to drop the amount I use from the utility.
Hi Tony. Thank you for watching and for your support. That is a good question. It is suppose to feed power to the loads once batteries are fully charged, however, I believe that it continues to power the loads through utility power once batteries are topped off. I hope that answers your question. Please consider subscribing if you found the content useful. Thanks.
How do you get to setting 28 to set up inverter?? I tried with the inverter turned on and turned off
What is the best set up for solar and generater when you use the generator to charge up when there is not enougf sun?
Hi Selena. Thank you for watching and for your support. I would say, for setting 1, to select UTI and for setting 14 SNU. Try that and let me know how it works out for you. Please consider subscribing if you found the content useful. Thanks.
Thanks for the overview. Looks like Growatt is made by MPP? Same menus. Same settings. Similar screen.
Hi. I think you are a 100% right. Looks very similar and as you stated same menu setup. They are very reliable inverters. Thank you for watching and for your support. Please consider subscribing if you found the content useful. Thank you.

i have a question. my inverter wont start charging from solar after cutting off power from a low battery voltage disconnect. what could be the challenge?
Hi. Thank you for watching and for your support. Depending on your battery chemistry the low voltage cutoff needs to be set at the correct level for your battery chemistry, if it goes too low your inverter may have trouble starting up because it does not have enough power to turn the inverter back on if that makes sense. I hope that helps. Please consider subscribing if you found the content useful. Thank you. Let me know if that works for you setting the low cutoff higher.
On progrm or setting 10 you have 2. My default aappears to be 4 and I cannot change it. When I touch up or down button it moves the program 10 11.
Help?
Hi Steve, thank you for watching and for your support. Mine is set on 2 and 10 because of my battery configuration, 24 volt. What is your configuration? Are you running 48 volts? If not check setting 5, if you had the firmware update, they changed 5 to have two user settings, USE and US2 now. Make sure to set it to USE. I remember that after I set everything up setting 10 was automatically configured. Hope that helps you in some way. Let me know if that helps? Please consider subscribing if you found the content useful. Thanks.
I just got my growatt hooked up, I have Generator I'm trying to use to charge at night and for some reason the display shows the ac input voltage but it is not showing the line to the charger or battery icon. Any ideas?
Hi Michal. I do have some ideas you can try. Go into settings Menu for 1, put UTI, for 13 or 14 change it to SNU. These two settings are the ones that change your Growatt so it is setup for generator or line connection. So I hope this helps. I had the same issue and it worked for me.

Great Video. I have growatt 24v 3000. It works good with two 24v ampere time lithium iron phosphates 100ah batteries from amazon. I have a 3500 predator generator that charges the batterys, I have three 185 watt panels but even here in Hawaii i only see 250 watts at peak times but its cloudy where i live and my panels aren't great. My problem is that the generator has never been able to charge the batteries past 26.5v even though everything is set to charge up to 28.2. and 100amp bms. I dont run much but seem to have to run the generator a lot any advise?
Hi A&WFarms. Aloha, I lived in Honolulu for 10 years. Miss the islands. I have had similar issues as yours. Check your battery when its charging during the day, you should see it go above 26.5 volts. At night when there is no charge it will rest at 26.5 as the cells rest at its nominal state of about 3.3 volts per cell. Let me know if you are getting a charge above 26.5 volts. Thanks for your questions. Please consider subscribing if you found the content useful. Thanks.
I would bump up solar to 1800 watts. Also my open circuit voltage is 120v.
Ok. You have to do some math. First thing is to know the max charge/discharge amperage of your batteries. 2nd thing is if you are running them in parallel you add up your amperages. I assume you are since you are running a 3000 watt 24vdc Growatt. 3rd thing to know is the max charge in amps,
26.5V is only ~3.31V per cell. The voltage will increase very slowly in this portion of the charging curve. Keep charging.
how does the growatt need to be grounded to the chassis? Is it sufficient to ground a DC negative bus bar where the growatt is connected to, or do I need to ground/bond the AC as well?
Hi. Thank you for watching and for your support. I believe that you have to ground the AC out as well. If you type in How To Ground the Growatt 3000, it will take you to some forums where you can get a lot of these answers. It seems like a long discussion. I hope that helps.
diysolarforum.com/threads/how-to-ground-all-in-one-inverter-system.13371/
I personally am going to ground my growatt with a grounding lug straight to my van and my busbar. The forums seem to suggest that the Case of the Growatt should be connected to the negative on the busbar. "So the inverter case is the ground. Good practice has the inverter case connected to the battery negative." Hope this helps.
@@thinkfreelivefree6951 thanks! When you say “grounding lug”, does that mean you create your own lug somewhere on the chassis since there is no dedicated one on the growatt.
@@rolandjuicebishop Hi, what I mean is that I will use a grounding lug that I will attach to my Van chassis and run a cable to my negative busbar that should ground the whole system. If that makes sense. I will do a video on that as soon as I get my inverter mounted in the van. Thanks. Hope that helps. Sorry its a bit confusing and seems that many people are saying different things, but if you are grounded to your batteries, your main power source to ground you should be good and connected to the busbar which everything else feeds from. Not sure what your application is, might differ for you?
What setting in 5 if battery has built in BMS ? Thanks
Hi G RB. Thank you for watching and for your support. If you have a built in BMS and want it to communicate with battery, it says in the manual to select "LI" for lithium in option 5. I hope this helps. Please consider subscribing if you found the content useful. Thanks.
I am trying to figure how to change from battery mode, to line one mode
Hi William. Thank you for watching and for your support. If I understand your question correctly, you are going to want to change setting 1 to UTI, Utility mode and also go to setting 14 and make sure it is set to SNU. That way your Utility Line Mode will immediately start charging your batteries through AC input. I hope this helps and answers your question.

can i use grow watt to charge my lipo4 battery without getting a battery charger
i am going to use prebuilt 24 volt battery
can i use grid to charge battery before going off grid
Hi Leonardo, technically you can, but its recommended to top balance your cells first. You can use an extension cord and cut off the output end and leave the input end so you can plug it into an outlet and connect your 3 wires to the input side of the growatt. You can also adjust the max amps allowed for charging. I have a video on top balancing before you use the growatt to charge your batteries. Thank you for watching and for your support.

Hello, I have a Growatt Off Grid Solar Inverter SPF 3000TL LVM 24P receiving PV from 3 panels 440w each, in series, able to charge my LiFePo4 battery (a custom built 4000w without BMS communication supplied by a local solar company) and power the loads in my trailer. The main appliance is a 548 kWh/year refrigerator, and there's a little reducer running at all times converting 120v into 12v for the lights (LED) and carbon monoxide detector. My challenge is the battery keeps dying overnight, and then I'm unable to power up the Growatt in the morning (even if it's sunny). I have no connection to the grid, and no generator (yet). My efforts to configure the Growatt to prevent the battery from draining to zero haven't worked. Ideally the Growatt would shut off power to the trailer once it gets to the low voltage setpoint (24V), saving enough power in the battery for me to turn it on again once it's sunny. Any help would be greatly appreciated!
Settings:
01 Output source Priority: SOL
04 Power Saving Mode : SdS (disabled, when I enable it, it immediately turns off the 120v to the trailer, even though there are loads)
05 Battery type: US2 (lithium battery without bms communication)
06 Auto Restart when overload occurs: enabled
07 auto restart over temp: enabled
12 setting voltage point back to utility source when selecting sbu priority or solar first in program 1: 24v
13 setting voltage point back to battery mode when selecting SBU priority or solar first in
program 1: (26v? I can't remember)
19 and 20: charging voltage and floating charging voltage: 28.2v
21: low DC cut off voltage: 24v
Thanks in advance!
@@rykelo8 Hi Ryan. Thank you so much for watching and for your support. I would try a couple of things and monitor your solar input during the day. Try changing setting 1 to UTI and make sure setting 2 is set to the maximum charging amps your bms can handle. Also I would change the low dc cut off voltage to 22 volts since you have a lifepo4 battery. 22 volts is 2.75 volts per cell. It may help you get through the night. Can you tell me more about your battery? I hope this helps in some way. I am aware that you are not using utility power, but as a test I just want to see if your solar array performs better running your loads and charging the battery. Please consider subscribing if you found the content useful. I have also had some issues with my growatt reducing my solar in the afternoon when it should be charging my batteries full force. Let me know how some of these adjustments work out. I also have mine set on SNU for setting 14. You could also try using the USE setting in option 5 and setting your bulk and float to the same value.
@@thinkfreelivefree6951 Subbed! Thanks for all the detailed info, I will be back up at my property in a couple weeks and will try your ideas then and get back to you. I'm in USE2 mode (lithium) and it seems like my Growatt allows only as much power from the panels as can be used by my loads and battery in real time. Unfortunately I don't know much more about my battery as a local solar business built it custom for me. There is no BMS connection to the Growatt, but there are these computer cards inside the container with the batteries that my guy says accomplish the same thing as a BMS.

Hello love the info. I am having difficulty setting up my low voltage disconnect setting 21. I have USE for setting 5. And when I try to set #21 to 24v when I hit enter it goes back to default which is 21v. Any insight is deeply grateful. I'm going to subscribe right now. Love it thanks for all your help and insight.
@@johnicaaracri5582 Hi. Thank you so much for watching and for your support. I have had similar issues. Try turning off your AC side and turning it back on and go back into setting 21, low dc voltage disconnect. It is suppose to be settable from 20v to 24v as the manual discloses if number 5 is set to USE. If it does not work. Contact Growatt. Hope this helps. Thanks
Menu 24: why have this disabled?
Hi MigMig. Thank you for watching and for your support. Setting 24 has to do with bonding the ground.
Where is the setting to equalize your batteries??
Hi Ivan, thank you for watching and for your support. Sorry, I do not understand your question fully, can you expand a bit? Thanks.
@@thinkfreelivefree6951 Would like to equalize the lead acid batteries. Usually there is a setting to boost voltage for 48v to 60v and rejuvinate batteries otherwise they go bad soon.
@@ivanvera7027 Hi Ivan. I am sorry, but I am not aware that the Growatt has those settings for lead acid batteries. However, you could set your parameters for your low dc cut off and your bulk and float charge in settings 19, 20 and 21. I hope that helps. Sorry I could not be of more help.
