We installed an on-board Progressive Industries surge protector which came with a remote readout which continually shows useful power data (real time volts, amps, etc.) and will also show failure codes should a power issue occur which the protector kicks power off on. Being on-board, theft not likely either. Can find them on Amazon, etc. for $225 range for 30 amp unit. I like the unit, find it helpful for occasional troubleshooting, and peace of mind against damaged appliances, etc.
