So I am looking at the 24v PowMr Solar Hybrid Inverter 3000W

Does anyone have a sugestion for a 24v solar charger inverter all in one that actually has built in bluetooth/wireless? Besides renogy 48v? everything I see requires a dongle like that Powmr or Sungoldpower.

I currently have a Renogy Rover 40A controller with 4-(100w) panels and 4-12v Lifep04 100ah batteries , I am replacing the whole system with 10-(100 W) bifacial panels and hybrid All in One charge controller

--- I want the grid backup as I have had tons of bad weather lately and its still summer, I can only imagine that the winter will make this system nearly useless.

--- I sort of want to put the renogy panels 2 facing east and 2 west to gather that morning and evening sun on the rover 40a so thats the only reason I am thinking of staying 24v.

Welcome to the forum.

I'm not aware of any, you should consider adding Solar Assistant.
As an FYI the units you are looking at are made by SRNE.

Are you planning to put the 12V batteries in series? Beware of potential balance issues.
Have you considered larger panels? It seems rather expensive going with 10 of the 100W.

Winter is tough. You should check out suncalc.org and pvwatts.gov if you haven't already.

One thing to keep in mind with the AIO you are considering is the minimum VOC needed to "wake up" the mppt.
I would plan to run those bifacial panels as a 10S string if you go that route.

Those panels do not look life bifacial!
On the Amazon pictures you can clearly see that there is backsheet. I suspect false advertising.

If your looking for small bifacial panels, check out Renogy, BougeRV, Eco-worthy and Newpowa brands.

I will need to look up solar assistant, no idea what that is.
2s2p was my plan with the batteries.
Those 100w panels are like $65 each, main reason is I have ecoworthy mounting system and a second one would hook right up to the end, would fit all 10 panels nicely. 1kw for about $700, other panels might work, I would prefer bifacial panels for help melting snow.
Yeah that was the plan to go series, that inverter can go 450v these should put it around 200v.

It sounds like you're on the right track.
I'd look at residential sized panels, should be able to get ~1KW for ~$300; but you might need 4 or 5 to meet minimum VO

I have the Powmr 12v 1.6kw version as a ups for my server Rack, the fans took a while to get used to and the soc seems to be completely made up but it seems to be a pretty good unit, I'm using a esp to decide the data and feed it into home assistant which is great as I can manage the load by automating wall/ceiling fans around the house depending on what it's pulling from the grid.
Only issue I have by not purchasing the WiFi dongle is being able to control settings on the inverter without manually changing them on the unit, somehow I need to figure out how to apply the settings password to enable remote control over settings.
Here's the thread that's discussing it if your interested.

Has anyone tried to use SRNE (Modbus ?) communication protocol with MakeskyBlue, PowMR or EASUN SCCs ?

I saw in several places that, MakeskyBlue, PowMR or EASUN Solar Charge Controllers are all re-brands of SRNE (or Voltronic) AND they are able to use SRNE Software applications with MakeskyBlue, PowMR or EASUN SCCs. If this is true, I am guessing one should be able to communicate (read/change...

Did you see my reply in that thread?
You can enter the password programmatically by sending it via specific Modbus registers.
