Question:
So I have a refrigerated trailer with 120 V refrigeration unit inside that max amps are 13.5 I’m having a hard time with startup running on a 4500 W 30 amp plugged generator inverter. Just wondering what soft star unit would work the best for that application.?

Expert Reply:
Hey Anthony! For your application the best option would be the Active Controls ActiveStart Plug-In Soft Start for RVs - 30 Amp # AS44FR. This is specifically designed to reduce compressor startup amperage and works great with generators that struggle during startup.
If you want built-in surge protection as well, we also have the ActiveStart Plug-In Soft Start with Surge Protection - 30 Amp # AS94FR. Since you're only pulling 13.5 amps, a 30 amp soft start is the correct size for your setup.
What kind of trailer do you have?
