Worth considering.....?

As much as I don't favor the all in one solar "generators" such as bluetti and eco-flow, lots of people have bought them. The issue is that although they are cool looking and nicely packaged, they don't offer true bang for your buck. Frankly they are 100% convienent but over priced for their output. They have vendor lock in for batteries. The newer models do offer split phase now so you can use them to run your furnace fans in the winter for example.

The best piece of equipment is the one you already own... so if you have one of these units, run what ya got. Some creative youtubers have discovered you can use any LFP 48v battery with the newer models so that helps with breaking thru vendor lock in. It also allows you a path forward if you decide to get a "real" inverter system later on because you can continue to use the LFP server rack batteries moving forward.

If you don't have one of these units, skip over them and get real inverters like XP6000, XP12000, or victron gear. Better in the long run.

I'm doing a little more refining on the source data I use for this home assistant energy graph page.

The top graphic is usage (above the center line) and production (below the center line). basically, the pink is energy that went into my battery early in the day and purple became the dominate color after noon when I was selling power to the grid. note that I always sell a little to the grid even when charging batteries..... after my batteries are full I connect the rest of the system to the grid and sell lots of power. Today I sold $7.55 in power

The lower graph is 5 of my MPPTs and the total power from each.. and the projected power. Today was cloudy so ididn't make what hte forecast said.

This is what the whole page looks like....

This says I'm 91% self-sufficient and that's because I export power to the grid and buy it back to power the cars. This scheme dings me for in/out of grid. And that's fine because if the world ends, we'll be driving a lot less. ha.

Today we made good power.... Had two EVs arrive home at nearly the same time and so both started charging at nearly the same time. At one point, I was charging two cars at a total of 16kw, running the house and still was selling 1kw to the grid.

It occurred to me today that once my battery gets to 100%, one of my 3kw MPPTs shuts down, so I changed the programming on one of my cars to have it charge at 90% house battery rather than waiting until 97%. That way I can continue to make up to 22kw while charging one of the cars. The reality is that if it's a sunny enough day that I get to 90%, I know damn well I'm going to make it to 100% and it's OK that I divert power from the house batteries to a car.

So today since we never bought power from the grid even when charging the cars, I scored 100% of my self-sufficiency. In addition we sold $10.37 to the grid above my usage.
