Hello Everyone, New to the site and first time posting. thanks in advance for any support.
I have a similar question as in the thread below but need some more answers as to how our system may work.
we have a food truck commissary where we would like to install 50kW of PV and a 90kWhr battery system but the problem is that we have an Open-Delta service from the utility. it has two 15kVA station service transformers and 12kV side of the two SST are connected to all three phases of the distribution line and the LV side is feeding us with 3-phase 4-wire system, 120/240V and a High leg at 208V. see example:
Question is; since i cannot find an inverter that will actually support the 3-phase system with the high leg at 208V; can we only utilize single phase inverters and only connect them to the 120/240V legs and not utilize the high leg phase (which is giving us 208 L-N)?
I guess we would in a sense be only using one of the SST which provides the 120/240V. Thankfully, we dont have any three phase loads so i dont need the 208V L-N leg but do have loads that utilize 240V. But i can easily add any of those loads to the other two hot phases.
Thanks again.

240V Open Delta PV connection?
Anybody out there ever connected a PV system to a 240 V OPEN Delta with a high leg three phase service? When we sold the job they told us the service was going to be a 208/120 Wye service. I'm guessing they switched this to the 240 Delta High Leg because it's a senior home and they have some...
