  <div dir="ltr"><div>Hi All,</div><div><br></div><div>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.</div><div><br></div><div>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.</div><div><br></div><div>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.<br></div><div><br>-- <br><div
