So what's the "Bees Knees" in single leg AIO's nowadays?

On a boat usually.
So I found out life is happening today and I need to rethink power for my dad's RV. What's the cost effective best bang for the buck in 5-6kw 120v Single Leg AIO's nowadays?

PowMr?
MPP?
EG4?
Sungold?

Everything will be in an insulated shed in Eastern Washington and no grid available so no need for outdoor rated sell back registered ULNECBMOC equipment. The camper has a 30a RV plug that feeds everything. I figure a DIY wall mount 48v battery or two and hopefully about 3kw of panels. I'm hoping something in the 6kw range so I have a little extra power for a small heat pump to heat and cool the power shed.

Set and Forget heat pump unit recommendations would be handy too so it'll automagically decide if it needs to heat or cool based on range.

Budget is a massive restriction here, so nothing Blue or made in Washington, I just can't afford it.

SRNE HYP or the older HF4850U80-H
Or step up to the ASP in 8KW or 10KW and configure it for 120V output instead of 120/240V. (Powmr and SGP relabel all of them)

I can confirm my Pioneer Inverter++ series works great heating and cooling in auto.

Edit to add - I think Growatt makes one in 120V 5KW output too.
 
Might look at the Pow-Sunsmart 6.5KP AIO offering. It is presently selling for around $1040. It can be setup either 1 phase 120vAC or 120/240vAC split phase . It also can be paralleled or stacked if in the future you need more power.

It is brand new on the market which means you will find no reviews about it.

That's a beefy unit. I wonder how accurate that 75w consumption is... 🤔
 
Assuming the heat pump is 240v it would seem to be an awkward situation to supply power due to the imbalance.
I might be inclined to get an AIO for the heat pump and a dedicated 4000w inverter for the RV. Both drawing from the same battery.
Or possibly a 240-120 transformer so the RV can load both sides from a single AIO.

The camper is only a 30a 120v plug, the heat pump would be a tiny one to climate control the power shed. I'm thinking an 8k or 9k would be overkill in there.

Count on 100W. Be thrilled if it's under 85W.
Probably. That 60w on the 6000xp kinda spoiled everyone, but I have no need for a split phase unit.
 
Do those stack?
Yes, up to 6.

Very nice..

I have to ask couldn’t you have just got the eg4 18KPV? About the same cost and less wall space?
Redundancy. If an inverter fails, I'm not in the dark. Also the growatt's have replacable parts and parts availability. Also the eg4 18kpv is 18k pv, not inverter. It's only a 12k inverter. I have 6 mppt's capable of 4kw each. So 18k inverter, 24k mppt.

Might need a minisplit that can be controlled by a thermostat. A smart thermostat, especially one designed for multi zone, might be able to switch between heat and cool based upon temp.

Hard to say. Tends to fall in line with how other AIO's in this range idle at. The unit does have SRNE type of features in description. Much better operation modes than the EG4 6000 which seem to be designed to be difficult for regular folks to set up. The EG4 does not allow single phase output nor does it have easily set utility or SBA modes and relies much more heavily on battery communication from my limited understanding of its operation.

It would be real interesting to have a side by side test of operation between the two. Hopefully some folks that end up buying the PowMr 6.5KP and using it will start posting reviews about it.

True enough. Forgot about that. Good point.

I'm looking for pretty much the same thing for my travel trailer. I've been looking at the ones you named and the Eco Worthy 5000W. I want all of the system except the solar panels built into the trailer for when it's used for travel, so compact size is a plus.
I'm heavily leaning toward the Eco Worthy at this point. They are on ebay right now with a coupon for $519.99. I'm just not sure if they are just complete garbage or a worthwhile option.

I've been running mine since the end of February with no issues. It's a rebadged SRNE HYP unit.

Two SRNE ASP 10k: 20kW output simpler install, lower cost, lower idle current ?
 
back to OP question:
I have a 9,000 BTU minisplit heat pump - with stat - has an "auto" setting - ie set temperature and it heats or cools as needed, BUT 240v
maybe there is a 120 volt option?

If the main energy use is 120, why not add a 120-240 step up transformer for the heat pump - these don't use L1 L2 N they are two wire - ie no neutral.
Not sure the cost in energy losses for the transformer though.
 
I've never seen a 9k mini split that was 240 in the US. I always thought the cutoff line was 12k where you could go either way. What's the make & model?

I'm thinking the PowMr 5k would be plenty. The camper can't draw more than 3500w so that still leaves plenty for a small aircon and lights in the shed. For $650 that seems pretty solid. Anyone got any input while I'm waiting on my slow ass internet to load some reviews.


On a completely different topic, does anyone make a 12v AIO besides Eco-Worthy or the MPP-1012LV?
