Thanks so much for this detailed video - was very helpful for my DIY project upgrading our 12 volt system to 24 volt! Cheers mate!

No problem I'm glad it could help

[@stevemizera3891]

Bought one, wired it as you presented. In the display at program 10 I cannot get it to move from 4 (for 48 volts) to 2 for 24 volt. It just jumps to 11 or nine. I am using 4 battle born in series/parallel.

HOWdy J-T-A-B, Thanks for the Walk-Thru COOP ...

[@woodknack1]

So how did you setup your battery in LCD setting 05? Did you pick lithium? Where you able to setup your own bulk charging voltage, float voltage and low dc cut of if you selected Lithium battery type? Curious how you setup you lithium batteries. I have the same setup for my camp.

[@HueNarcisWorld]

Few questions: Can you turn off the inverter? (I only need it sometimes) Can the inverter be turned off via the wireless stick? is there a option to manage it by cable? On another note, mind the fuse: in the manual I found this: "SPF 3000TL LVM-24P / Maximum amperage 141A / Recommended battery capacity 200Ah". Thanks !

[@kickgas7171]

This Growatt high frequency, transformerless inverter is great for powering resistive loads and small electronics but it won't last very long powering inductive loads like power tools, refrigerators, motors, AC units, compressors or microwave ovens. High frequency inverters like these were never designed for powering high surge loads. You may get lucky and this inverter might start a few of these inductive loads when the inverter is new, but as the inverter ages, 1 1/2 to 2 years down the road, the inverter will fail sooner, rather than later with continuous use with inductive loads. I've repaired inverters for a living for the past 23 years and one thing that I've learned is that the surge current that's generated by these inductive loads will damage the MOSFETs (metal oxide semiconductor field effect transistors) in this inverter and will basically brick the inverter because the hourly shop rates for troubleshooting, testing and replacing all those MOSFETs will exceed the value of the inverter. It would be cheaper to simply replace the unit. A much better choice is one of Growatt's low frequency transformer based inverters. You'll be much happier 10 years down the road.

[@JR-kk6ce]

I heard one of the drawbacks of the All in One is that they consume a lot of power with the inverter always in standby move. From what I heard you need an additional 500 watts to cover the standby power consumption.

[@J-TAB]

Here is a manual that says it takes 50w to run but can be put into low power mode that only takes 15w watts247.com/manuals/gw/SPF%203000TL%20LVM%20Operation%20Training.pdf

[@HomesteadDad]

One year later how do you like it? I am thinking about putting one in a bus renovation. Thanks.

[@J-TAB]

Hey! Man these are great super simple and just works .... It's hard to say about mobile application tho because the battery can only be charged by shore power or solar because of the 24v which isn't bad in a trailer but in a van/bus situation you will be missing out on the alternator charging really wish they made a 12v version with a 30-50 amp dc to dc charge controller for mobile applications.....

@@J-TAB I won't be boondocking for extended periods so I think I can get away with shore power or solar only for charging. I like the idea of 24v for the better efficiency over 12v. Could a step up converter be used if I really wanted to use the alternator to charge? Thanks for the prompt response!

How do you hook up 2 more 12v batteries into it. That's whare I get confused...

[@J-TAB]

Hey! This is not a great video on the subject but is accurate I hope it helps.... kzbin.info/www/bejne/o36meZuhhrJlnrs

[@Tumbleweed5150]

To make the 24 Volts, we put two 12V batteries in Series, hooking the negative of one battery to the Positive of the other, then taking the 24V off the two terminals left. In order to hook up two more 12V batteries, you connect them together in Series, then hook up the two sets of two in parallel by hooking the 24V terminals of each set together, positive to positive and negative to negative. There are many DIY channels that show how, including DIY Solar with Will Prowse.

[@ibrahimfatawu2640]

Thanks for the review. I hope it can work without the AC input?

[@J-TAB]

It should

[@vandweleer8004]

Good video! how many solar panels are you using to charge up batteries ? also if you have 2x200w(solar panels) how long it takes to FULLY charge those (2) 100Ah battleborn batteries ?

[@jamesshomesolarmore2223]

Loaded question 400 watts pv is at peak pv power. most areas have about 5 to 6 hours of solar hours. that's different from sun hours. then your voltage and watts must be figured out to get the amps for the battery charging. every set up is different. I have 12,000 watts solar. with 100 amps per hour of charging capability into a 600 amp hour battery bank. It takes until 2 or 3 in the afternoon to recharge my batteries.

[@jamesshomesolarmore2223]

these are 48-volt battery system. are you running 12 volt or 24 volt?

[@AGhostInTheMachine]

Isn't that 250A fuse way too high for that cable?

[@J-TAB]

Yes but it is just a test bench.... with these inverters I would recommend really using a thicker cable and make sure you use actual copper cables not that aluminum clad cable

with the AC out for the unit to go to shore power to charge, do you need it if the RV has an outlet for pluging into shore power?

I would have to look at what you are trying to do I don't have enough information ..... if you mean "do you need to hook up shore power to the growatt if the trailer has a shore power plug?" I would say yes "if" you are wanting to charge the unit off shore power and if you are wanting the rv to utilize the transfer switch..... but i would also say it really depends on you setup.... You "might" be able to use the shore power plug that is already on the rv

[@johnmarkm.5743]

Great video! Can you do an efficiency test demonstrating efficiency running a fridge, speed drill, miter saw (especially the miter saw) and a blender?

[@J-TAB]

Yeah I will definitely do that...

[@johnmarkm.5743]

​@@J-TAB nice!.....One more curious thing I'd like to know is what wattage it idles at when you set the priority to Utility and it's doing absolutely nothing just running off the battery with no power from Utility. In some other video someone had it on SBU and it was pulling 5.2A just to remain ON which is alot, way too much for just idling! The trouble with the power saving feature though in many inverter/chargers is running something like a fridge, once the fridge stops periodically, waking the inverter seems to be an issue so the fridge won't work but I don't know whether this is the case with Growatt, can you also test that?

[@J-TAB]

Hmmm I will have to get some additional testing equipment for that... maybe I can hook up a smart shunt and see if I can measure it....

Same goes for when there isnt "enough" watts in the PV, like the solar makes 500W, the load needs 1000W but instead of taking 500W from solar and 500W from the batteries it takes 200W from the PVs and 800W from the batteries.....

@@cowboymcq6711 I am still NOT clear with 12v vs 24v system .... Im kinda lost

[@J-TAB]

It really depends on you situation..... if you are in a vehicle where you main system is 12v anyway than 12v is best but if you are in a offgrid situation than it can be beneficial to go with higher voltage for better efficiency...

[@czthor1]

Should have listed what parts you used and where to find the parts.

[@J-TAB]

Hey thanks for the comment! I kind of did but I guess I was not clear but I have updated the video's description

[@rjbass338]

any update to this video?

[@J-TAB]

Hey soon I will be uploading another video on this ..... I actually had to swap this one out for one that a friend of mine bought. His mppt whent out and I got a replacement board for it so I will be making a video about that as well

[@eddiekytia]

I'm looking to try my 1st build,and want to use a all in one solar inverter but I'm looking for a 2000 watt system and can only find it in a 24v system so how would I get some 12v outlets.... thanks for your help.... and I did just subscribe

[@J-TAB]

Hey! Yeah I have been trying to find a smaller setup also .... but you can convert 24v to 12v with something like this ..... amzn.to/3vDyvAO ... or this amzn.to/3puUmJz ....... also thanks for the subscribe!

[@Tumbleweed5150]

@@J-TAB That second one is one I tried before, but found it to be underpowered. I bought one that looks just like it but was 24V to 13.8V at 40A output, which works well.

It can but it's only one way.... it wont back feed to the grid.... only cut to grid when overloaded.... hope that helps

[@morgananderson9647]

I'm so happy you did this video! Thank you so much! I know some inverters have a higher surge rate above their constant general output. E.G. when an appliance starts up even though its rated for 1000 Watts, many times they exceed there constant state running draws. I was curious how this unit would handle that. Also since they are so small & compact, have you considered linking 2-3 in parallel to get say 6000/9000 watt capacity for the ability to run multiple electrical devices, like a shower heater, water pump, Oven/instapot or Microwave, inductive stoves, perhaps a large 27' -to 26" monitor/big screen all at the same time? I know they may put out some heat so placement could be an issue. Curious as to your thoughts...

[@tempvoid7680]

Hi, thanks for your video, just today i installed the very same model here for our off grid setting. In the Day time it seemingly worked well, except the fan, which was working all the time, even though today was a cold and rainy day here. I have a question regarding the stand-by mode at night. having no experience it seems to me that every minute, the system tries to start itself, all the indicators blink a few times, then the LCD Display tuns on and the fan runs. After one minute everything goes off, Again after one minute the whole process repeats. it goes non stop. Is this behavior a normal stand-by mode for this machine? I am wondering because there is no fault code indicated in the display, and there is no such situation explained in the manual or on the Trouble Shooting table. I appreciate and value your kind effort and time....

[@J-TAB]

Hey! (Sorry late response) No I don't think it's supposed to do that mine only kicks on under heavy load ..... If you have found a solution or figured anything out let us know thank!

[@diy-bj2ed]

Did you buy that growatt inverter from amazon ? Been seeing them on Amazon but not sure if they're knock off or the original unit

[@J-TAB]

Hey, No I did not I have updated the description and added a link to where I got it from.

[@athertop]

I'm thinking of doing a sprinter van conversion and considering 2.8kw induction hob for cooking, so this unit looks like it would do the job. One concern - how many solar panels in series to reach the operating voltage of that Growat system. Also, do they do 230v ac versions?

[@J-TAB]

Hey Paul! As far as how many solar panels to reach peak voltage it depends on the open circuit voltage of the panels you are using.... And as far as the 230v you can either link 2 of the units together or if you are wanting it a little simpler you can use one of these watts247.com/product/spf-6000t-mpv-dvm/?wpam_id=81 ...the are 6kw and have 230v

Well I will definitely push it and see what we can get out of it .... let me know if there is anything else you want me to check before you buy one ..... also they do have them on amazon amzn.to/3qHQEtz

[@MaxCloutier]

Did you end up making your van build using that after all? I'm currently looking into components I'll need for my 1700w solar array, 30amp + shore power, and 300ah 24v battery system and the price adds up quickly if buying all the components separately. i.e. just an inverter/charger is more than this whole thing and you still need to get the solar charge controller and a lot more... Just wondering if it's a viable alternative on the road :) thanks!

[@J-TAB]

Hey! Yes I have put one in a bus and it works great! Check the link in the description I think they are on sale right now at watts 247..... the only thing I had to add was a dc to dc converter for the 12v led lights
