you're welcome!

Awesome presentation, thank you!

I'm glad you're finding it helpful!

[@cruikshank]

Thank you 🙏 now to decide do I go All in 1 or separate components. I was going to go separate until you made me aware of the All in 1. Other than EG4’s I had no idea this was an option. I wish I knew the statistics of the long term reliability of the All in 1. I got 2 WattCycles and 4 panels, this would finish the project. Thanks again.

[@texasprepperprojects]

Welcome

[@USL.Website]

Hi, thank you for making the video and good advice. I just wanted to ask if the two 12V batteries are connected to make 24V, will they not get unbalanced over time. I would imagine in this case, a battery balancer will be needed, please let me know what you think your advice is valuable to all of us, thank you again for your time taken.

[@texasprepperprojects]

In theory, if you have two 12v batteries in series, that you use every single day, yes, there is a chance that, over time, they can get out of balance. If you are that worried about it then just keep a 12v charger like the one I reviewed a few weeks ago and every few months disconnect everything and charge them independently.

[@USL.Website]

@@texasprepperprojects Thank you for the excellent advice, your advice is also saving me money, which is so appreciated. I am going to do just that: charge them every now and again independently.

[@larryseibold4287]

Unless i am missing something, the all in one also has a line interactive bypass (transfer switch) and control switches to chose the source (grid, solar, solar+grid,) plus output (batt, etc). This allows it to work as a UPS, with only 22W of power loss vs 10%. That is worth another $200 or so. I would pay a few dollars more if it also had 12V and 48V battery options, but 24V is a good choice. I like the small and low cost part.

[@texasprepperprojects]

Yes. I think you are asking too much for multi voltage since the charger and the inverter has to be made specifically for that input voltage. Besides 24v is the best anyway

[@mrhalfstep]

You're right. You can program the priority that you want into this and other "all in ones" and it will act as a SUPER UPS. It will charge by solar as much as it can and will add in grid power if it needs it and it will provide AC power from solar if it is available and only use batteries when solar is unavailable. That discrete component system just can't compare.

[@MerwinARTist]

Got mine ordered .. it's on the way! Thanks for the heads-up!!

[@texasprepperprojects]

What are you doing for batteries?

[@MerwinARTist]

@@texasprepperprojects I ordered the 2 12v Li 280 Watt batteries .. they have been sitting here waiting for 24v 3000 watt unit to come back in stock. I have 5 - 315 watt 8.45 amp used solar panels that I'm going to build a tracking system for. I have this question tho .. is it possible to plug into the grid .. and charge one of the 12v 280 watt batteries to capacity .. using the 24v 3000 watt solar inverter charger?

[@MerwinARTist]

@@texasprepperprojects I'm seeing that it shows a 50 amp AC input .. so I assume that means a grid connection .. but you didn't discuss or show that part of setting it up.

I literally take a power strip and cut the cord off to use the male end. I have a video from Nov that shows this

[@kirok3184]

Why does the charger look like it's higher on the left side compared to the right? Cause it definitely is not square to the board. My OCD runs 24/7. I really want to build something like this if I had the extra cash. Love your videos. 👍

[@texasprepperprojects]

Its probably my tripod

[@Scott-ig1zd]

How loud /quiet are the fans? I have 250 sqft cabin. That idle consumption is less than half of what other 24v AIO inverters draw. I have a small system almost the same as the one you have in your video 2000w inverter, 50a epever mppt cc, 24v 120ah battery with 4 250 watt panels.

[@texasprepperprojects]

Not bad

[@nats50]

Stupid question from a non-techie guy with regard to solar panels and such, but concerned about power outages, which is getting more frequent in California, can you use that particular setup you showed on the solar panels used on homes? Thanks.

[@texasprepperprojects]

I'm not clear on your question

[@nats50]

@@texasprepperprojects I mean, these power stations like Anker, EcoFlow, and others, usually come with their brand of solar panels. My question is, those solar panels usually installed on homes, are they compatible with this setup, or they are a different breed?

[@texasprepperprojects]

Its all the same thing. The branded panels are massively over priced. As long as the output voltage of the panels is within spec of your charge controller your good

@@texasprepperprojects thank you for checking, I will reach out to them, and will let you know.

[@texasprepperprojects]

Welcome

[@MyGuyKirby]

Being a bit under-educated on series batteries, will the charger try to charge each 12-volt as 12 or push down 24-volts and let the batteries just fill up to capacity?

[@texasprepperprojects]

It charges as 24v

[@texasprepperprojects]

When you series two 12v batteries together then you need to think of them as 1 unit. The charger doesn't know the difference between 1 battery or two. It's just sending out 29v

[@MyGuyKirby]

@@texasprepperprojects Thanks, appreciate the conversation and the information you are sharing. I'm in Houston area.

[@g-whiz286]

@@texasprepperprojects - 2 AWG wire for the battery seems a little light. 3000 Watts at 90% efficiency is 3333 Watts. 3333(inverter input power)÷22(low battery cutoff volts)=151.5 Amps (which is close to the spare battery fuse you mentioned. 1/0 wire is good for 150 amps which is right on the bleeding edge. I would prefer to see 2/0 wire rated for 175 amps as it provides a little breathing room with that 150 amp fuse (looks like an ANL fuse). Remember, the fuse is sized to protect the wire. The wire is sized to support the maximum possible current draw.

[@texasprepperprojects]

But 9kw is the max draw and i can't even imagine what load that would be. Also, the terminals going into the unit aren't big. It comes both ferrals for 2awg. Look at the connections on the unit. While a 2/0 might be best i don't think that logistically you can get them in theree

[@danieltimisan6820]

is that 22w idle consumption in “save mode” or normal save mode is not working all the time also .. what about monitoring app ?

[@texasprepperprojects]

Normal mode. I am not familiar with an app for this unit

[@jessesioux4431]

Dang. 2 of the watt cycle 12v 280Ah minis in series would really work well. But I only got one battery

[@texasprepperprojects]

Grab another now!

[@vorgon]

One of the problems I have will all these low end combo's is, they are 120, We have 240 split phase. The other, I've been looking at these inverter with limiters that have a clamp on power monitor and only provide what you need simplifying when you are grid tied. But, again, I've only seen one brand, Sun I think it is, and they make a 120 and a 240 that is NOT split phase. They also are only the inverter and you can get them to ether take solar directly or battery. Still need the battery controllers because solar without batteries is a waste of money I think.

[@texasprepperprojects]

I have seen a lot of 249 split phase out there. Look at signature solar. It's just not going to be $499

[@mitchevans8214]

I have received mine. Can you tell me what to get for solar panels, with 1600 pv input could I get 4 400 watt panels or would that be to much? If it's over 1600w will it damage the unit

[@texasprepperprojects]

My fav is used residential panels from facebook. they are typically 35 volts, so you could put 3 of them in series to get just over 100 volts and that would be right around 1,200 watts or so. In my area they are about $80 each

[@mitchevans8214]

Thanks

[@texasprepperprojects]

@@mitchevans8214 welcome

[@retrozmachine1189]

There's a technical difference between the all-in-one on the left and the separate items on the right, and that is isolation (separation) between the PV and AC sides. With the separate items there is transformer isolation (in the 24V > '400V' section of the Giandel inverter) between the DC and AC wiring so you can for example disconnect the PV and the MPPT charger's terminals are safe to touch. With the all-in-one potentially this is not the case. It's very very common for these things to have no transformer of any type between the PV and AC wiring - PV goes into the HVDC bus and the components that produce the AC output are also direct onto the HVDC bus. Disconnecting the PV does not make the inverter's PV terminals safe. Safe working practices will ensure you are fine but there's abundant examples of amateur youtube solar tinkerers getting a belt off the PV terminals on an all-in-one. Make sure *all* power sources, *all*, are disconnected before coming in touch with the terminals and that includes uninsulated screwdrivers. Keep safe.

[@texasprepperprojects]

Nice info!

[@bigdaddydoitall]

What are your pv string specs for this? I have the same unit.

[@texasprepperprojects]

30 to 105v

[@g-whiz286]

Does this unit have the ability to throttle down the AC charger? 29.2 volts at 50 amps and assuming 90% charger efficiency is about 1622 Watts. My little ALP propane generator tops out at 850 Watts. At full charge current, this will easily overload my little generator. If I could back off the charger to 50%, the charge current would drop to 811 Watts and my little generator would be happy. Is there such a setting?

[@texasprepperprojects]

Yes you can

[@akhenatn]

If you use 3000 watts at 24v is about 125 amps. And that 4awg wire is not enough to hold it. At least u should use 2awg and 1/0 might be better

[@texasprepperprojects]

I'm using 2awg but I can't imagine anything in my house that I'd run on this that would pull 3,000w

[@g-whiz286]

9000 Watts for 0.5 seconds Is a huge overload capacity. It is difficult to believe this (along with the 41 lb. weight) is not a low-frequency inverter. It is seriously overbuilt if it is a high-frequency inverter.

[@texasprepperprojects]

I agree

[@retrozmachine1189]

I would want to see measurements that support the claim personally, ie traces of the voltage and current waveforms.

[@gregs6252]

I bought one of these. There are 2 groupings of 3 large bolts on the back, my guess is 2 huge coils, so I would say it's a low frequency inverter.

[@retrozmachine1189]

@@gregs6252 It weighs 20kg, you might be onto something there. HF steel cased units of similar specs are usually under 15kg. LF all in one is not a common thing. If it is then my comments about PV/AC isolation would not apply since it has transformer isolation.

[@rafaelo2215]

your argument is to buy an extra 3 in one inverter? so instead of spending $500 for the inverter than it will cost you $1000? ,.. and that is not including taxes and shipping ... 3 in one inverters is only good for convenience and space ... if i going to but an extra 3 in one inverter then i going to use it ... the 2 most important thing of a 3 in one inverter is the MPPT and the inverter ... the charger is for emergency only unless you want to use it as a UPS

$750 worth of separate parts or $500 for an all in one. Replacement parts are up to you but that's a 50% cost savings.
