Is the below search info below not correct? I am thinking you would set the Xantrex to only input 15 amps from shore power or generator then it would kick in and provide the next 10 amps or so with a 3000 watt inverter?
How would the Xantrex know the difference between shore power and generator?
Yes, Xantrex has a feature similar to Victron's Power Assist. Xantrex Freedom SW inverters and chargers include a "Generator Support Mode" that enables the unit to assist a generator when AC loads exceed its capacity. This functionality allows the inverter/charger to provide additional power from the batteries to supplement the generator, similar to how Victron's Power Assist uses battery power to supplement a limited input.
Here's a more detailed explanation:
Victron's Power Assist:
This feature allows you to adjust the input current to a level lower than the output power without affecting output power. It allows the inverter/charger to use battery power to supplement a limited input like shore power or a generator.
Xantrex's Generator Support Mode:
This mode is specifically designed for RVs and boats. When using a generator, it allows the inverter/charger to draw power from the batteries to assist the generator when AC loads exceed its capacity.
Key Difference:
While both achieve the same goal of supplementing a limited power source, Xantrex's Generator Support Mode is more focused on generators and RV applications, whereas Victron's Power Assist can be used with various power sources.
