[RE-wrenches] Adding generators to PV systems

[Tump]

2 suggestions; the first is installing the GT inverter output on the utility side of the T switch 
( Manu’s recommended spot)
. The second is have the generator tech set the frequency a bit lower then 59.5 Hz. (57-58 Hz.) which is usually the lower spot where the GT inverters will latch on and begin to output. Make sure that this setting is noted on the generator so the next tech will leave it at this setting.
