would it interfere in any way with my inverter/charger?

To an inverter/charger (or other appliances), it is nothing more than a direct connection to AC mains. One can confirm this with a meter or continuity checker.
Key to making that unit effective is where is must be located. "Plug the Surge Guard ... into an approved RV receptacle and plug the RV power cord into the Surge Guard." This means its MOVs have a shortest (low impedance) connection to earth ground. And are farther from the inverter. Only then does it provide protection from surges that MOVs are intended to avert.
However (and its spec numbers are not clear), it appears to be seriously undersized. Effective protectors for this type of protection should be at least 50,000 amps. This is only 6500 amps (maybe more).
Its other features make it useful.
All appliances already have surge protection. I would expect the inverter to meet same industry standards that make computer and other electronic power supplies so robust. Before PCs existed, industry standards put that protection at 600 volts for 120 volt units. Today that standard protection is closer to 1000 volts.
Your concern is a rare transient (maybe once every seven years) that might overwhelm that protection. A number, that can also vary significantly even in the same town.
