Hey everyone! I'm looking to install a 10kW hybrid battery system and I currently have a 6kW PV setup running on a separate inverter. I'm considering adding more panels with a DC connection during the install of the battery. My question is about the max PV input power of the hybrid inverter, which states it can handle 10,000W. Does this maximum include the capacity of my existing system (which is AC) alongside the new DC input, or is it just referring to the new DC panels? So basically, can I connect a total of 10,000W between the existing 6,000W (AC) and the new 4,000W (DC), or is it strictly 10,000W from the DC input alone?

Great question! The max PV input power of your hybrid inverter refers only to the solar from the panels connected to it, not the AC side of your old system. So, in your case, it can handle 10,000W solely from the new DC solar panel setup. Even if your existing system produces more power, the inverter won't utilize it. Just keep the total input at or below the 10,000W from your new DC array.
Just to add, it’s important to check if you have any export limitations since you’re grid-tied. If your inverter has a limit, make sure you're within that to avoid issues with feeding power back into the grid.
Good point! My export limit should be 10kW, so that lines up.

Thanks for clarifying that! That's exactly what I needed to know.
