We just had our unit worked on at rally because of some ongoing issues that the Super Solar had in most units. In the Super Solar, the sole purpose of the PD52 was surge protection. It already had the Magnum Hybrid inverter, Charger, transfer switch. I was told all of the PD52’s are failing. For us, I didn’t need the transfer switch function, just the surge protection. I opted (on my dime) to add the Hughes Watchdog EMS instead of adding the Southwire. The nice feature for me is I am using the Bluetooth to monitor power. That probably isn’t an option for some, but it is a great path for Super Solar owners. If you need to replace a PD52, another option would be a straightforward transfer switch and a hardwired Watchdog. As bright as the Watchdog is (bright white light when power is good, red when there is an issue) makes a target for theft. Plus, if you get a surge on the Southwire, you get to replace the whole unit. The Watchdog you can replace the whole surge component for about $40. Just an option.
