I'm in Northeast and would like a reliable backup system for 1-2 days in case of power outage for a fridge and a small space heater plus light.

If you can use a heat pump a battery system may make more sense, for example Ecoflow Wave 3 is rated at 6800 BTU heat output for 700W DC input, which would be powered by Delta Pro 3 for 5+ hours.
For light and refrigeration a single Delta Pro 3 is fine, expansion batteries can be added as needed to give you the runtime required.
