So did you bond the RV plug neutral to the neutral in your main panel or does the line in on the Growatt already do that? I'm doing a similar offgrid setup so my main panel is grounded and bonded. My understanding is for fault protection, you'd want to bond the neutral of the RV plug to the main panel neutral since the gas ginny is a floating. Lots of confusion around that though online. Curious to your thoughts..
That was an awesome video and setup. Your organization is top notch! I have setup Growatt SPF 3000TL LVM x 6 units parallel operation in split phase with 3 in each phase. I attempted to add a generator when I started with 3 units but it is a 10kW regular construction generator. The manual states you should use a diesel generator. You have totally debunked that notion. With the knowledge you have given me I am going to rewire the communications to 2 inverters per phase and use an inverter generator. I recommend Heliene 400w solar panels. I have 18 and they fully recharge my system by noon on a sunny day. Please video your next step. You have a new fan.
Appreciate the kind words! Inverter generators are where it’s at! Construction generators “can” have high THD at loads over 20-30%. If in one’s budget an inverter generator usually gives superior results! Take care, be safe!
I've got the 48V version of this - just one unit for single phase 120V AC. It's gotten me through a couple outages and I don't regret having it (despite not having it set up with solar panels yet). I do wish it had a 'max ac input power' limit you could set to tell it 'You're connected to a 2200W generator, don't exceed that - provide pass-through power & adjust battery charging down to as little as 0% accordingly'. Some hybrid inverters have settings like this. With these SPF3000 units, you have to adjust the battery charging amperage down manually to compensate, or just settle with like a slower ~500-900W charging rate for plenty of headroom. I've got the EU2200i now too, and just like the Growatt inverter itself, it can quite comfortably handle my transfer-switch with all 6 of its circuits - gas furnace, fridge, most lights, and a good number of commonly used outlets during an outage. If I also want it to charge/top off its batteries at ~1500W, that stands to overload even this little legend of a generator, hence the desire for a 'max ac input power' option.
My Growatt came in today. I am working on getting everything together. I really like it so far. It seems very well made. Thank you for recommending it to me. Very nice set up I have one question about the exhaust system. Do you have a thermostat on it? Reason I am asking is I know you get colder than we here down south. I would love to see the setup settings.
Thanks for posting your video, great work! How did you physically and electrically connect the RV twist lock cord adaptar to your inverters? Did you have to install some sort of relay and breakers?
Wired to input of the inverter. The inverter will automatically connect with its internal relay and charge the battery bank at your programmed charge settings when the generator is connected. Hope this helps!
Thank you for giving your knowledge, I am ready to purchase the bus bars, can you recommend the amps and number of 5/16 studs I need for a 4 battery sok 24 volt system?. Thanks again to you and Dave.
Great video, a lot of info!! Thanks! I got a couple questions i couldnt find after goong through your channel. How long does it take you to charge your battery bank using just the generator? And your battery bank is similar to mine in the way you have the batteries in series and parallel. What kind of voltage do you read at on the growatts when you have a full charge? What kind of time frames are you getting out of the battery bank? My system is very similar, 2 growatts in parallel, and similar battery bank but smaller. Still waiting on the rest of our batteries to get here. Great content!
I don't why, but I wanted to tell you I'm not receiving notifications for all your videos. I am subscribed and have "all" picked on the notifications. Also wanted to let you know I live somewhere near Spartanburg, licensed Ham and GMRS operator, life long prepper.
Thanks for the heads up about the notifications. I don’t know why that is happening… Awesome that you’re a preparedness minded individual! 👍 Keep it up!
Thanks! This particular setup is 120v single phase with the inverters in parallel, I will do an update video soon and include more details. I’ve had several questions on the generator connection. Thanks for watching and commenting!
Looks great. Nice work. I love my Growatt inverter. One question, how does one determine if a system can handle adding more batteries? Currently I have one 48 amp lithium ion phosphate battery connected to a 3000W Growatt inverter and have four 320 watt panels run in series. Thanks for doing these videos
When charging with the generator do all the AC loads get put on the generator? If so I assume the charging current is only what's left over after supporting your loads?
This type inverter is passing generator power through the inverter, powering loads and charging the battery bank simultaneously. If it was a battery charger only (dc switch relay) any generator would work. An inverter generator is best in applications like the one in the video. One can change the settings in the Growatt to accept a generator with higher THD (construction generator) but this poorer quality power would go through to the loads as well. Hope this helps explain.
Man, this is awesome! So can you make a video explaining what each is purposes for? For instance, I assume the generator is the input of voltage to the Growatts - the Growatts convert the voltage for storage - the batteries store the voltage... but I notice you have direct wired from the Growatts to a breaker box... why? So it’s immediately available outside of storage?
Whats the growatt settings you have set for the generator input? Is there a setting so if loads in the house demand more the generator wont be overloaded and the inverter will stop charging and assist the generator with the load?
1000 watt array per Growatt to start. Idle consumption powered up I measured 1.3 amps +\- per inverter. Roughly 34watts. The solar arrays will be documented in another video. Hope this helps!
Thanks for showing us. I am in Maryland. Do you know anyone that might be able to help with 2 system installs? Could I contact you with some questions? Just met with my electrician today about panels and he does not do them.
Hello my friend i have a couple of eco flow delta max 2000 watt and im wanting a solar system to charge that and ive done reseach but theres sooo much you have to know when buy solar panels and charge mppt controller 24v or 48v and i was wo dering if you would actually kinda help me figure it out without wasting alot of money and then it not work. Sorry for bothering you brother. Thank you and God bless
Your EcoFlow machines have a built in charge controller. Just look at the specs, and match panels to the machine. Hope this helps, feel free to contact me through email if you need more assistance. I’ve also got a video on testing a huge array on a Zendure power station if you look in my solar playlists.
Owners choice to have a remote power house. Growatt is not UL listed. SOK batteries have low temp cutoff protection. The power house is well insulated and the heat from the inverters in winter will keep the room warm.
I thought you were gonna show us how you wired the generator in to the Grow watts. I have the same setup but when I wire in the generator it says uneven power distribution…
I have two of the same inverters and have some specific questions on how the generator is connected if you could assist. Mine are wired one to each side of the breaker box Plug coming from ac input to outlet. Generator runs house and powers outlet. Problem is unless I trip input breaker and switch over generator breaker I get errors/warning bells so I’m sure something is not correct. Any input?
Is your generator back feeding the breaker panel or into the Growatts? Are the inverters synchronized in parallel? Or are you trying to do split phase with the LVM sub models? What type of generator are you using?
Just to clarify…. Husband who was the electrician now has dementia so I am not sure anything is 100% correct so hoping to redo it the right /better way if that’s the problem
Sounds like there may be more going on than I can help you with in a comment. Sorry to hear about your husband. Does he have any friends in the electric business that may be willing to lend a hand to someone in need? This may be your best and safest option!
Unfortunately no. We know very few people in this area. Family that could help is 8 hours away. I tried to hire electrician but he doesn’t know solar and one solar company in the area only works on systems they install. Quoted me 18,000 for four panels and 2 lead acid batteries. Thanks I’ll keep watching videos. It’s working and has been for 2 years. Just hoping to make things more efficient
Wow super impressive! Thanks for showing us a tour.
Glad you enjoyed it!
That is a super nice power shed! Very clean, neat installation! I really like those Growatt inverters.
Thanks! Growatts are really nice inverters!
35 years as en electrician. You guys do neat work.
Thanks for the kind words! 👍

Thanks for sharing your experiences with the Growatt platform! Overall it is a good unit especially considering the low prices!
Great little video and a really nice install. Great job to you and SP1!
Thanks! 👍
You’ve got a pristine installation going there. Thank you for the video. God Bless!!
Thanks 👍

Make sure the bus bars are rated at a higher amperage than your maximum load/surge on your system build.
Great video, a lot of info!! Thanks! I got a couple questions i couldnt find after goong through your channel. How long does it take you to charge your battery bank using just the generator?

I’ll be making another video on this system (not my system btw) before too long and will try to answer your questions in the video!
I don't why, but I wanted to tell you I'm not receiving notifications for all your videos. I am subscribed and have "all" picked on the notifications. Also wanted to let you know I live somewhere near Spartanburg, licensed Ham and GMRS operator, life long prepper.
Thanks for the heads up about the notifications. I don’t know why that is happening…
Awesome that you’re a preparedness minded individual! 👍 Keep it up!
Very clean install. Is this setup in split-phase and if so how is a 120v generator wired to both?
Thanks!
This particular setup is 120v single phase with the inverters in parallel, I will do an update video soon and include more details. I’ve had several questions on the generator connection.
Thanks for watching and commenting!
24volt is the survival voltage! I have 24volt, would love 48 but i will always have a 24 volt system for shtf
12/24/48 all have their pros and cons. 24v is a great “all around” option.
how do you coordinate the unit with the inverter? how do you make their phases the same? do the inverter and the generator have grounding?
Looks great. Nice work. I love my Growatt inverter. One question, how does one determine if a system can handle adding more batteries? Currently I have one 48 amp lithium ion phosphate battery connected to a 3000W Growatt inverter and have four 320 watt panels run in series. Thanks for doing these videos
Hard to properly answer your question with a comment. I’ll address your question in an upcoming video.
When charging with the generator do all the AC loads get put on the generator? If so I assume the charging current is only what's left over after supporting your loads?
Depends on some of the user program settings! Look at your P01 setting to start! Hope this helps
What type of battery disconnects are you using, How are the rated?. Very neat work.
Blue sea disconnects, I’ll put a link in the description. 350AMP up to 48VDC.
@@THEOFFGRIDMOUNTAINHOMESTEAD I'm told blue sea is the best!
Blue Sea disconnects are very heavy duty and have an excellent build quality!
What would potentially be damaged from using a construction generator? I thought they were safer for constant loads like charging batteries?
This type inverter is passing generator power through the inverter, powering loads and charging the battery bank simultaneously.
If it was a battery charger only (dc switch relay) any generator would work.
An inverter generator is best in applications like the one in the video.
One can change the settings in the Growatt to accept a generator with higher THD (construction generator) but this poorer quality power would go through to the loads as well.

I’ll be going over this particular system in greater detail and how everything functions in upcoming videos.
Whats the growatt settings you have set for the generator input? Is there a setting so if loads in the house demand more the generator wont be overloaded and the inverter will stop charging and assist the generator with the load?
What size PV array is planned? Do you know what the idle consumption is on this model?
1000 watt array per Growatt to start.

Reason for putting or not putting all this in a basement....risk of fire? What about the cold weather effecting the batteries
Owners choice to have a remote power house. Growatt is not UL listed. SOK batteries have low temp cutoff protection. The power house is well insulated and the heat from the inverters in winter will keep the room warm.
I thought you were gonna show us how you wired the generator in to the Grow watts. I have the same setup but when I wire in the generator it says uneven power distribution…
These were not my Growatt units. They most likely will not be seen on film again. This system is undergoing retrofits and upgrading.
👍👍👍
I have two of the same inverters and have some specific questions on how the generator is connected if you could assist.
Mine are wired one to each side of the breaker box
Plug coming from ac input to outlet. Generator runs house and powers outlet.
Problem is unless I trip input breaker and switch over generator breaker I get errors/warning bells so I’m sure something is not correct. Any input?
Is your generator back feeding the breaker panel or into the Growatts? Are the inverters synchronized in parallel? Or are you trying to do split phase with the LVM sub models? What type of generator are you using?
Generator does power breaker panel. Inverters are not in parallel. I need to rewire/move everything anyway so if there is a better way I’m all ears.
Just to clarify…. Husband who was the electrician now has dementia so I am not sure anything is 100% correct so hoping to redo it the right /better way if that’s the problem

Do you offer consultation services
How can I get in touch with you ?
Feel free to find my contact information in the about section of the channel. Thanks for watching and commenting!
Why not a 48 Volt? You know the higher the voltage the more efficient it is.
Owners choice. Growatt does claim 93% efficient on these 24v inverters.
Very similar efficiency to 48v inverters.
With all the inverters it seems its only a 1 or 2% difference in efficiency
