Decision summary

Where this model earns its place

Best fitWhole-day backup with a large solar array.
Main compromiseAt 115.7 lb before the cart, this is installed equipment rather than something portable.
Direct-price context$3,999.95, checked Sep 21, 2026 on the official manufacturer page. Promotions and list prices change, so treat this as the price on that date rather than today.

How the record reads

Energy, output, and the appliance are three separate gates

The battery decides duration. The inverter decides whether a load can run and start. The appliance decides the voltage, connection, and surge demand that must be met.

Refrigerator planning profile

An estimated 61.4 hours from the visible defaults

This calculation uses a 150W running load, 1,200W starting load, 33% duty cycle, 90% usable capacity, and 88% AC efficiency. It is planning math, not a measured refrigerator test.
