Great demonstration! I’ve been looking at this inverter for a while. Didn’t. Know it had the feature to auto start and shut down a generator if needed. I’d love to see a short video on that process working.
Most of the all-in-one units have this dry connection for generators like the generac standby generator. I do not have one to demonstrate for you. One day when I win the lottory maybe :)
@@Roll2Videos I’m using the EG4 batteries from signature solar. I’ve got 3 of them currently, and I’m hoping to purchase another 3 in a couple months as money allows. I have the setup in my shop and I’ve already got the inverters wired up to the batteries and the sub panel in there. Everything has tested well. I’m ditching the inlet power line to the inverters today.
Excellent review. Really hoping that Growatt makes a 5000W model like this where I can use 2 in parallel to get split phase. Their 12KW model is an excellent device but given that it's low frequency, it's quite heavy.
@@2olvets443 yes they do but i discovered you can't parallel them to make a 240 split phase like you can with their 3000w model. they 5000 model can only be paralleled for single phase 230/240 or 3 phase.
Nice to see that battery kick out 125A at it's 24 volt nominal. I think I'm going with the Growatt LVM-24P over the MPP LV-2424 after watching this video. Watts247 is a great resource for DIY'ers, too. I'll be sure to use your link as a thank you. ;)
SPF 3000TL LVM-24P In this model inverter, should I use lithium phosphate battery. Or just use lead acid. Because I have seen the data sheet, the data sheet only mentions the name lead acid battery. Please give details.
Thank you for all the extra information.. ie: planning your solar panels to meet the GrowWatt's VOC requirements... One question though... You mentioned that you have to pre-charge the inverter when using LiFePO4 batteries... What do you recommend precharging for normal usage? TIA.
The dry contact used to be for neutral bonding through an external bonding relay. I wonder if they have put the bonding internal now. I'd suggest doing a test on grid vs off grid with an outlet tester and see if the neutral is properly bonded in both positions now.
@@Roll2Videos It's one feature I really wish they'd make internal at this point. It wouldn't even cost them much to do so. At least with the old dry contact setup there was an easy way to do it so the bond moves to the proper location. My 48 volt units have been running for 2 years now and have held up well.
Yes, you can set the charging amps. The unit will show the SOC through wifi reading volts witch works with lead batteries. If using lithium you'd need a bms that can communicate with the growatt to get that reading accurately.
Hi. I have the February newest version of this growatt 24 i have hooked it temporarily to 4 / 400 w panels in series. Next I will add another 400 w in parallel and attach to a combiner box. How many of these 400 strings Can I add ? I assume 1800w total. Am I correct? Thanks btw
I have a very similar setup as yours. I cannot figure out how to hook up my has generator to charge the batteries. Can you please show me where to hook the generator up. I tried putting a cord in the AC in but it didn’t work.
Hi, I have growatt inverter 5kw ES, i installed 4 gel batteries 12v 100ah, my question is what is the battery type that i should use, AGM, Flooded or Use and if Use what is the charging voltage, floating charging float and low DC cuttoff, and if possible should i use battery equilizer option for gel, and if yes how to use it.
That's a lot of questions lol. I'm more familiar with lithium I'd say refer to your owner's manual and use your preset battery options use gel with gel.

Thanks again.
Hi there, can this all-in-one prioritize on battery over grid? Meaning, will it wait until the battery bank is fully drained at night before switching back to grid power?
@@Roll2Videos Thanks! And will do. The link to the manual on the watts247 is 404, but will look on grow's site too).

Looking into getting the 24v 3kw model to replace my Aims 24v 4kw inverter.

@@Roll2Videos lol, I hear you. It's just that I have some spare 1/0 awg cables that I could use. Just wanna make sure they can fit properly. Thank you.
19.6a * 120v puts it over the 2k watt limit if you ever actually hit the max. It is my understanding you don't use the VOC for this calculation but the Vmpp * Impp have I been misinformed? With VOC there is a multiplier depending on what the low temperatures get to in the area you live. I have this system with very similar Array.
Great question. The manual says 145 VOC maybe they have the difference built in the that VOC. I'll have to look into that more your way sounds more precise
@@Roll2Videos I think that is the volts either when cold or extremely warm that the system can handle. But you wouldn't use that for calculating the wattage hence using the other optimal volts with normal conditions. Here we adv high 20's to 30's for lows but have had teens so for 5-15*F the factor is 1.16. My Voc is 120.9 on the series total, 120.9 * 1.16 = 140.24 VOC which is below the threshold. My Vmpp is 33.9 each so 101.7v for series Impp is 18.74 for the 3s2p. 18.74 * 101.7 = 1905 watts. If you find I didn't get this information right please let me know as then I would also be over wattage for the Growatt.

Very good information I need to look into this more myself. I believe my system will work I'll post a fire video if not. As far as the 15a inline fuse you'll want to put them on your series strings before you parallel them. th-cam.com/video/s1P31hxlD3I/w-d-xo.html Great guy to learn from.
They do make a 5000w you can ad the transformer so you get both 120 and 240 you only need one unit and the transformer i a growatt dealer if you want a deal and you can stack 6 but only need one abs a transformer
It will also bring up your surge load so it don't turn the unit off can start bigger loads like AC units transformer ads another 7500 watts of surge per unit
@@xwongx Yes you can totally take power from the batteries and it won't mess up the unit. You can even get a buck converter to go from 24v down to 12v if need be.
Hi, how much energy does the inverter consume while is working We are just using a couple of light bulbs and the battery run out during the night The battery is a 2.5 kWh growatt Thanks

Hi. I have the February newest version of this growatt 24 i have hooked it temporarily to 4 / 400 w panels in series. Next I will add another 400 w in parallel and attach to a combiner box. How many of these 400 strings
Can I add ? I assume 1800w total. Am I correct? Thanks btw
I think 4/400w panels in series might put you over your open voltage circuit rating of 145 volts
Do you have to use the negative cable to check the amps or can you clamp the positive?
I could clamp the positive but I always see shunts hooked up to the negative so I figure that's what should be measured.
When you do dual phase split input, do you have to get some kind of Power reduced box to get to 120?
A single Growatt will only take 120v if you have 2 Growatts you would put leg 1 into the first unit and leg 2 into the second unit. Follow the manual.
@@Roll2Videos
I don’t have a growatt, just trying to understand the basics of split phase. How are you can have 240 and 120 at the same time. 🖖
Sorry to ask s stupid question: what AC volts you get? We have appliances running on 240v on Grid in UK. Thanks.
For this model 95v to 140v Growatt has other models for the 230v UK market
If your off grid why do you need a transfer switch ? To swap over to generator power when one cell kicks the BMS off ?
Yes you could use it with a generator if you have a low battery situation. It can also be used in a mobile system for shore power hook up.
Buy the 5000 es us abd they sell a transformer and you connect them and it's both 120 240 and 2 times the surge
Good suggestion
