Selection Advice
The GAVR-15C is widely regarded as the highest-quality model in the domestic GAVR series. Compared to the 15A, it adds low-speed protection (automatically reduces voltage when generator RPM drops too low to prevent equipment damage) and enhanced EMI filtering for only $5 more. The GAVR-15B is the mid-range option. The AVR15A is a simplified version with no protection features and no filtering — only suitable for minimum-budget scenarios.
