Need advice on how to expand
My question is similar to some of the other recent posts but didn't want to hijack them, I have 15kw solar on a 15kw 3ph inverter, gateway and 16kwh of batteries on my house. I want to add more panels with a standalone Sig inverter and have a couple of options but unsure of what the capabilities and limitations of the Sig system are:
Detached garage with a 20a 3ph supply, can I add another 8-10kw of solar and 3ph Sig inverter using the existing supply instead of a dedicated cable back to the gateway? Dedicated ethernet is available.
Sleepout with 2ph supply cable from gateway but only 1ph used, can I run a single phase inverter on the unused phase but sharing the neutral? I assume the 3ph house inverter will work to balance out the phase loading based on the grid CTs? Only shared ethernet available from here but wifi to both.
Thanks
