Is the Yoshino 2000W enough to run a fridge?

Yes for most refrigerators, which draw a few hundred watts running and spike higher at startup. The 3,000 W peak covers that surge. It won't run a whole home or 240 V appliances.

How is a solid-state battery different from lithium-ion?

The electrolyte is solid rather than liquid, which Yoshino says makes it safer and longer-lived. The 4,000-cycle rating is higher than the 500-1,000 cycles typical of older lithium-ion stations.

How fast does it recharge?

Yoshino rates it at 0-80% in under an hour from an AC outlet. A full charge takes somewhat longer. Solar recharge depends on panel wattage and sun.

Can I control it from my phone?

Yes. It has smart app control for monitoring and settings, plus wireless charging for a phone on top.

How heavy is it to carry?

31.3 lbs, which is manageable for one adult over short distances. It is lighter than most 2,000 W-class stations, which often run 40-50 lbs.

Does it work with solar panels?

Yes, it is designed for solar input, though panel wattage and connector type determine charge speed. Check that your panels match its input before buying.
