Increasing KO size voids warranty. In the past, SMA might repair a dead modified inverter, if possible, but would not exchange one. The logistical difference is, you have to send your modified defective inverter in and wait instead of receiving a refurbished replacement promptly.

Pretty tight for the 3/4" knock-outs in that inverter. Any harm in using a step-drill to open it up to a 1" KO? Any experiences with this? I'm trying to avoid a J-box with a transition to 8 Gauge with 4-14 Polaris connectors.
