    My initial thoughts: 
    Clever design, good form factor across the range. Makes for scalability very easily. I  don't know the pricing but I can imagine it must be expensive. Also it uses AI to manage it's entire system on how you will use energy. So AI is great when I works but what happens when it doesn't? Imagine the frustration of trying to work with a system that is planning your usage & you not really part of that conversation. 
    I like automation & lived with it in life critical equipment & it worked very well. AI unfortunately for me takes the leap a bit far because you are observed but not privy to the information. I like to know what a machine has planned for my house hold energy management. Also I think there needs to be a manual mode where one can manually do what they want to do. 
    I hope there are these modes but for a residential modern home that will have an EV at some stage it's great. However, AI is relatively new...I would hate to be the guinea pig. I see that some want to use this on the Heavy C&I market & thats where I think the right tool for.the job comes to mind. It doesn't have a transformer so my guess is that it's a Gate Drive system. 
    Unfortunately I don't have much confidence in that architecture for Heavy industrial places. 
    Looks super modern & promising. Looks like it will be judged as time goes by but most average ppl will just buy a more simple easy cheaper manageable system that's not complicated. Maybe I'm just old & sceptical...

    Hi Brad, you have accessed it well. In order to create a Micro Grid ie. Have Grid tie inverters connected to the load output of Large Hybrid inverters you need an Energy meter to carry out the Measurements of what the Grid ties and or Load is doing. That Energy meter allows us to via Modbus send production throttle commands to the Grid tie inverters. I have used most brands and they operate on the same principles. When the Grid ties produce more than the load, the power is exported into the LOAD port into the inverter. The inverter will suck up that energy into the battery and charge up. When we reach 95% we Throttle the Grid ties to follow the load only (Zero Export). We have successfully added our EMS controller into many of these control scenarios with very good results.
    Please send me a PM if you want to discuss further or have a project requirement. This is a niche market and there are probably a handful of operators and EMS creators that can achieve this. I'm proud to say my company is one of them. Further to that of the handful only 4 of these companies are local and once again proud to be one of the local EMS producers finding solutions for large Commercial Solar Plants ...
