I currently have a 15KW hybrid inverter set up designed for net metering, but since the utility company declined that route, I've converted to a hybrid system at a significant additional cost. My home typically uses less than 4KWH during the day, meaning a lot of the solar energy produced is going to waste. I want to upgrade my 2.2KW EV charger to an 11KW one so that I can maximize the use of my solar energy during the day when I'm home. My current charger mostly runs overnight using grid electricity and charges slightly during the day, but it's a slow process. I'd like recommendations on what to consider when purchasing a new 11KW EV charger that can communicate with my inverter to adjust power based on available solar energy minus household consumption. I want to make the most out of my investment and ensure that I can charge my EV efficiently during sunlight hours.

Have you checked which make and model your current hybrid inverter is? For instance, SolarEdge offers EV chargers that can be directly connected to their hybrid inverter, making it easier to prioritize excess solar energy for EV charging. Just make sure to look into the technical manuals of potential EV chargers to see if they can interface with your inverter, especially for managing excess power situations. That's key!
I'm using a 15 KW Solax X3 LV Neo Hybrid Inverter, but I'm feeling a bit concerned after some issues with it. Solax offers EV charging options, but I'm hesitant about them. What do you think of having an 11KW charger with a 15KW inverter? The inverter can also dip into the grid if needed.
