All other things being equal, if you had to pick between either the MPP LV2424 or the Growatt 3000TL, which would you choose?

I've basically narrowed my search down to these two all-in-one inverters and am leaning towards the MPP. It seems to have a solid user base, decently documented features (if not by MPP, by the community members), and can be monitored easily (https://diysolarforum.com/threads/monitoring-mpp-clone-systems-with-freeware-pi-grafana.15712/).

The price is about the same for both. The Growatt provides a bit more power on paper (how truthful are these numbers) and Will seems to be a fan. Both are typical China quality which I'm ok with. Current supply seems to indicate that the Growatt could be a while before it is shipped (early May on watts247.com) and the MPP is in stock.

Really a tough decision I think.

Other aspects of my system:
  • 8x 272Ah LiFePO4 cells from the Lishen group buy taking the extremely slow boat from China (so the shipping time for the inverter may be moot) in a 24V setup
  • TBD 8S BMS - probably overkill
  • 2x300W solar panels that I got from Craigslist very cheap. I'll replace these eventually
  • Mostly used as a battery backup for computer systems, refridgerators, basic lights, and maybe 1-2 hours of space heating/window AC use (600W for heater, 650W for AC)
  • Probably add an inverter generator at some point too
I have some more details and the background of planning my system on my blog - https://austinsnerdythings.com/2021/03/15/my-diy-solar-system-with-battery-backup/

I was about to post the exact same question ... we have rto replace several systems out here and I am trying to decide between the 2424 MPP or the Growatt ....

Going to say that you could probably UP those 2x300 to about 20X300 ...LOL

I'm hoping someone jumps in and does a good comparison ...

In fact a side by side (@Will Prowse) comparison would make a great video ...

I understand the excitement over the Growatt BUT at the same time I also like that the MPP has been a workhorse for a long time and had a great following ... we have about 10 of the MPP 2424 out here but zero Growatts and the team hates it when we atrt mixing and matching -- so it would really take something to switch from MPP to GROWATT ..... but my job is to continue to find the best(est), fastest, cheapest ...

@Will Prowse I do think that this would make a good and relatively straightforward video for you to do -- side by side comparisons ...

Thx

I recall reading somewhere that @Will Prowse preferred the Growatt but don't recall where. I'm sure he has both but yes, a side-by-side would be great. Or Growatt/MPP can ship me one of each and I'll do it for him LOL! I still haven't decided.

Another consideration is that 8S 100A BMS's are very common. 24V*100A works extremely well with the 2.4kW MPP. The 3.0kW Growatt would be stretching it a bit.

Gosh they are practically the same. And manufactured by voltronic. The only real difference I have found is that the growatt has a better manual and some of the growatt distributors have better customer support. That's about it. Both are great units. And if you open them up, they all look the same. Voltronic manufacturers most of these units: https://voltronicpower.com/en-US/Product/Solar-Products/Off-Grid-Inverter

Growatt seems to manufacture their own grid tie inverters. But I could be wrong. Please let me know if you find their third party manufacturer.

Excellent -- thx for the update -- YES that would make for a very short video ...LOL ....I guess we will continue with the MPP since we have established a good relationship with them and although their manual does lack they have very good customer service and they speak English really well ...

Thx for letting us know

Is that Growatt 3000 model LF transformer based inverter compared to LV 2424 HF inverter?
I believe Growatt is weighted in at over 30 lbs compared to about 17 lbs for the LV2424, so Growatt may have better surge capability than the LV2424.
