Latest, good All-In-One - mobile, EG4, SunGold, Growatt, Chins - single phase, 3kw

[chrisstratton]

Any thoughts on which might be the current 'sweet spot' for a mobile All in One, 110v, single phase, 3000w, to handle less than 2kw PV? I've used the Growatt 3000 for two years and it was good. Occasionally I would disagree with the Growatt's choice not to charge the LiFePO4 when on shore power. But, by and large, it did what I asked it to do. Now, I've sold the motorhome and I'm looking to build another. Thoughts - anyone?

cant beat the 400 usd units from powmr (SRNE rebadge) shipped from US warehouses and with 2 yr warranty.

Everybody’s “sweet spot” is different lol. There are so many options these days. It really comes down to warranties and whether or not they’ll be honored, which is why I generally agree with the statement above about PowMr as long as I can find it on Amazon and get protection on it so I can easily send it back no matter what.

Thanks! I was wondering about them. Last time, I made a 24v system. I'm thinking about a LifePower 48v server rack battery: does it make sense to run the 48 volts ot one or two distribution sites, then down convert to 12?

By the way - many of those are 230output, I'm going to guess that balanced draw is important and one should just randomly take one leg for a 110v fridge and another for an induction burner?

Those are not split phase. Just 1 phase 1 neutral and 230v between the one phase and neutral. European

Seems the US 110v ones cost at least 460 usd.

They have pro's and con's, but as a general overview:

EG4 - Pro- Can take higher voltage strings for larger arrays, Pro- Local (US at least) support, Con- Higher than average standby draw, Con- Needs a good amount of panel to just turn on.

MPP - Pro- Just Works, even Will says so, Pro - very trusted brand that has been doing it a while, Con- Lower PV voltage max which usually means getting a combiner box involved, Con- Different versions of the same thing don't like to stack

Growatt- Pro- About the same as the MPP for longevity and support, Pro- Often times has a little more capacity than the MPP of the same range (3kw vs 2.4kw for the 24v units for example), Con- Has been known to have charging issues from the grid, Con- Not being developed so don't expect many firmware updates in the future.

PowMr - Pro- CHEAP!! Con- CHEAP!!!

I've currently got a 3000 LVM-ES and really like it. Communications with the EG4 Lifepower4 works very well. That being said, if I was gonna do it over again, I'd get the EG4 3k unit that comes with battery cables and offers 500v solar input so I could run a single string. Only downside I see to the EG4 is the 18amp PV input whereas the Growatt ES offers 22amp solar input which offers more flexibilty for parallel strings. EG4 also has a much longer warranty.

What are the idle powerdraw of those aios? The srne (powmr rebadge) i got have 50w idle and 30watt in power saving with inverter sleeping but ready to go

I'm in the same boat (figuratively). I've narrowed down to Growatt SPF 3000TL LVM-48P and MPP PIP-3048 LV-MK. Since I only have room for 4 panels, partial shading concerns on my backyard shed means I have to stick to my 60 cell used panels in 2s-2p configuration which fit well with the above inverters. My only comparison points are: Low idle consumption in inverter mode, decent Wi-Fi smartphone app experience (with their respective dongles), fan noise. Which would you guys recommend?

Hmmm … 120 single phase? I’d say most seasoned RV types go with Victron Multiplus units.
3000 V-A seems to be the most used.
