Hello all,
I pulled the trigger on (2) LV6548 hybrid inverters. https://watts247.com/product/2-x-lv...ar-inverter-8kw-2-x-4kw-250v-mppt-bms-ul1741/ . Also have purchased a pallet of 435 watt solar panels. The plan is to run both in split phase.
I've been studying the manual but I'm quite confused on the AC wiring.
Currently, I have 1 main panel (connected to grid), 200A service.
The instructions state, "Before connecting to AC input power source , please install a separate AC breaker between
inverter and AC input power source . This will ensure the inverter can be securely disconnected during
maintenance and fully protected from over current of AC input."
I'm not sure what size breaker to use from my main panel to the inverters. 60A? 100A? I believe the "AC In" will be for the grid assist if the solar/battery is not meeting the load.
The utility, I'm confused on what to do with the neutral. I get each hot wire, will go to a separate inverter (from a breaker in the main box). However, the diagram doesn't really show what to do with the neutral wire.
For the load, it shows the neutral being bonded and ran into each inverter.
Can I use my main panel, for both the AC In, as well as Load? So I would essentially just be installing 2 double pole breakers in the existing box.
Or should I wire up a separate sub panel for the Load? Extend existing circuits (that I want to run on solar/battery) to the new panel?
What would be the best way to handle the neutral for the load? Just use the neutral bus bar (from potential new sub panel) and run to each inverter?
Thanks in advance.
