I have significant professional experience with Tripp-Liite and think very highly of their products — no affiliation now, but I worked for some of their resellers in the past. So while my electronics are well protected against surges, blackouts and brownouts, they’re not well-protected against modified sine-wave power produced by my generator.

Only a dual-conversion AKA true online UPS will take modified sine-wave power and turn it into true sine-wave power.
