I keep learning and my 48v/110v inverter needs to be a 220 inverter to feed my breaker box and most inverters are similar with two outputs. Both 110? Many inverters are like this. 220$

The key factor isn't the number of outlets, but whether your inverter supports 240V.

A 240V inverter will explicitly state "240V" or "split phase." For a split phase inverter, you'll need four wires: two load wires (L1 and L2), a neutral wire, and a ground wire. Based on the picture, it seems the inverter has two 120V legs that can connect to different circuits. Given the $200 price range, it likely falls into what I would consider the "junk" category.
 
So many ads show this same setup. they advertise 240v. almost every inverter looks like they come from the same factory. the expensive inverters look the same. ebay, amazon it all looks the same. If I painted this box blue it would look like a victron. It is hard figuring out what brand is reliable and within my price range. so I need a split-phase inverter?
 
Let's go about this a different way, what is your budget for a reliable 240v inveter? Let me know and I'll give you links to quality inverters to choose from.

If you have 120V and 240V circuits, and you're in North America (or a region that uses the same 120/240VAC 60Hz power), and you want to duplicate this power source with an inverter, yes.

SINGLE phase 230V/50Hz tend to be cheaper than an equivalent yield 120/240 split phase inverter.
 
If you only need 120v outlets because none of your loads are 240v (stoves, pumps, aircon, etc) then your unit ONLY needs to be 120v and you can feed that to a breaker panel just fine.

Breaker panels in north america are designed for two legs of 120v, and 120v + 120v = 240v for high power loads.

Converting a 240v breaker panel to only feed 120v loads is just a jumper wire. Super easy.

Maybe 500 to 800. Yeah, I did notice many over a thousand, Many Chinese models for a few hundred. Grow Watt has been mentioned a lot but looks like another Chinese model. I've had good experiences with Japanese products, any inverter manufacturers from Japan?

Okay, and are you intending to run your whole house, a garage, barn, granny flat? $500-$800 isn't going to get you a new device that will run your entire home, and you're most likely looking at either some used equipment or potentially some smaller inverters that could run small loads, also are you going to install batteries or is this a grid-tied system with no backup?
 
I can run 120 with my Chinese inverter for the moment. I have done more research and better inverters are low-frequency transformer based, I wonder how many companies make a quality inverter that lasts. It's a big investment for a puff of smoke. I need an inverter for my houseboat to run an air fryer a microwave and an instant hot water heater. if they're all on at once. 30 amps. I wanted to use an external dual pole 60 amp breaker to feed the boat 240 at the sub panel from a solar generator trailer. (boats on dry land ) The cheap inverter can only feed 120 It's not the way I want things in the long run. 48 volt system with solar and wind dumping into a water heater for a radiant heat system. with a pump and a water heater tank circulating hot water and also feeding the instant hot water. I get so much wind the 48 v DC water tank heater will run off the power from the wind turbine. Fed from a diversion charge controller. In a perfect world anyhow. I've been gathering together parts and I'm making this happen over the next two months.
This has been a good example of the need to invest more right off the bat and stay away from cheaper inverters.
