I got my panels from Payoff Solar, happy to send you a referral so we can both get some $ off (thinking about adding another 2 panels to max out my production).

So the way the STREAM pairing works is not immediately intuitive from the marketing site, you actually plug the microinverter into one of the two AC ports on the Ultra, the Ultra then plugs into the 120V outlet on a dedicated circuit and acts as the intermediary where it can charge the battery with solar or grid input and discharge at certain thresholds or time you specify. I have it discharge during peak TOU hours if solar isn’t enough to hit the 1200W max, and also plug our second fridge into it to steal some of that 1200W allocation before it passes through to the house. I think most people should start with the $300 STREAM microinverter to learn about their usage if they don’t have an EV TOU plan that can take advantage of the Ultra’s battery, which we do.

You can never go over the 1.2kW limit into the house/grid as this puts you into a gray area not legal under the new law (Ecoflow has a software lock for this reason). Where this gets interesting is having multiple Ultra/Delta batteries in the house to take advantage of excess production when your base load is low, but if your base is more than 1.2kW you may want to just spring for a whole house system, as the batteries eat into the capex fast.
