Any better alternative to MPP PIP 2724? 24v, 2,700w All-in-One unit

Hi everyone. Just joined this forum. So excited to continue my education.

Just starting my solar journey. Spent all last week going down the rabbit hole to try and educate myself.

Because I live in Vegas and it's freaking hot decided on a 24v system so I can run a portable AC unit.

Already ordered two 12v 100ah LiTime batteries that I will put in series. Originally was looking at the MPP 2724 because I've seen it in a few of Will's videos. But I've heard concerns it is really, really loud. It will be in my living space so that's a definite concern.

Are there any other alternatives I could consider to the MPP that won't break the bank? btw, I found the MPP at an MPP reseller for $391 out the door so I think that's a pretty good price.

The reason I was trying to put together a system with and all-in-one inverter/controller is because I have zero solar and zero electrical experience so was just trying to make it a simple as possible. But didn't want to buy a "power station" like EcoFlow or Anker because I think this would be an invaluable skill to learn. But to go with all separate components scares me a little.

What do you guys think? Am I on the right path?

oh, if anyone needs the MPP specs they are here: https://maximumsolar.online/product/pip2724lv-mr/

====================================================

UPDATE 04/15/24: Thanks you guys for all your comments, advice and help!

Between the MidNite and Growatt which do you think will have quieter operation? It will be in my living space most of the time, so noise is a definite consideration

I have a MPP2724 for my mobile set up, it is a very capable little unit and is the only AIO (I know of) with AC outlets built right into the inverter.
Is is pretty loud under load, or connected to PV, and is limited to 800W PV input (ie not much) making this more of a portable or RV suitable inverter.
I can tell you with 200A of battery behind it, the little MPP2724 will run anything a 120-20A wall outlet can, including things like a chop saw, a wire feed welder or any portable tools with a typical 15A plug on them.
For your home, I don't think this is the way to go. That said, lots of inverters are "kinda loud", not suitable for a living room because the cooling fans are going to cycle and you will be wishing you put the inverter in a garage soon enough. Best to start with more research I would say.

Thanks for the info! I agree with you, I think the 800w PV is a little limiting so I'm now looking at the MPP LV2424. It's a little more money but has 2,000w solar :)

In that range it is pretty much a Voltronic or SRNE. The MPP is Voltronic.

There is many companies that offer them under their own label. The SRNE (Midnite solar rebadges this one) is a 3kW unit that has either a low PV VOC 100v, 60a (1440w) or a high PV Voc 450v, 80a. The high one allows up to 4000w of PV but obviously with 80a max charge this means that it maxes out at +2000w and the rest would be overpanelling. Another advantage of the High Voc model is it will feed from solar even when battery is charged or there is no battery just PV and utility connected. Disadvantage is you need 150Voc to start and a minimum of 120v to operate.

Also I do not recommend that you series connect LiFePO4 batteries.

Chances are if you are running an Aircon unit the fan noise will drown out the fan noise from the AIO.

The LV2424 is a loud beast with high idle consumption as well as a RFI generator. I plan to get rid of mine when the 48v inverter is installed.

Thanks Matt. I'm doing more research on the Voltronic and SRNE. Given my admitted ignorance with solar and electricity (but I'm learning...haha), why do you suggest not connecting the two 12v batteries in series? Interestingly enough I wanted to make sure that was possible so emailed LiTime customer service and the response was no problem as long as they were balanced. btw...LiTime CS was great. Very responsive.

Copy that. It seems to be the resounding theme for the MPP 12v and 24v. Since it will be in and around my living space I need to look elsewhere. Or, even though I have literally zero experience perhaps I should look into separate components? Putting it all together from scratch does seem intimidating though. I just need something quiet and able to give me about 2kw

I have the exact battery running on the Midnite 3024 .Two 12V for 24vdc

LifePO4 batteries have their own BMS. Placing them in series can and often does lead to balance issues and trips occurring. When running this way the advice is to every few months separate the batteries and charge individually . No one does it and ends up with issues.
 
Well, he is right in the old days I think and if I am correct. Just ensure your cables and breakers can handle the load.
The batteries can handle far more after that.
We usually run this over 2000w just not for really long periods. It's just a backup and display(connected to Grid as well )
But runs daily

Ahhh...okay. Yes, I remember reading something about this when connected in series

Good information. But haven't had any issues for over 6month since the installation.
I should have mentioned it's a bit of an experiment as well so will be looking for trips.
We did full charge separately before install though.
