Hi All,
I've been asked to review a GT-BBUS that was installed with a DC to AC
ratio of 2.14. The system owner is frustrated b/c his 9.2-kW of PV is
bottlenecked by an 80A MPPT (~4,300W). The inverter is a XW-5548 so
there is a second bottleneck to overcome even if an additional CC were
added.
My inclination is to install a GT inverter for half the array and make
a separate point of connection. I have considered adding a transfer
switch on the PV conductors to allow the owner to toggle between this
new GT inverter and the existing CC. I thought that having the option
would be of benefit during extended outages with little sun.
I'd be curious to know if anyone has had to solve a problem similar to
this one and if they were able to find a suitable switch. To-date, I
have not located a good transfer switch or breaker assembly with
handle-tie etc... Any thoughts are greatly appreciated.
