My PowerMax converters (100a, 75a, 55a) have all met and exceeded their amp ratings (103, 76, 56). There are two main reasons for not reaching converter rating:
1. Using #8 output wiring. Needs #4. Their instructions are not clear about that.
2. Low 120v input. It runs but at lower amps . . .
When I used my 60a PowerMax, input voltage was 122v under full load. Output was connected to several different discharged batteries and dc loads with 3 ft. long, 2 gauge cables. Output current would never exceed 53-54a. Same loads connected to a PD converter produced rated current.
I'm not saying PowerMax converters in general do not produce their rated current. What I am saying it's possible PowerMax may have quality control commensurate with their pricing.
