Usable capacity in these units rarely exceeds high 80% and when it does it's because they under-rate the battery. Given that this inverter is able to put a 2C load on the battery, it is understandable that the efficiency will take a hit due to the standby power draw will be double of the normal amount when compared to a unit with 1:1 ratio capacity/power output. Say at a 0.2C discharge rate the battery will empty in 5 hours, but in those 5 hours the inverter's standby consuption is 20W*5hrs = 100Wh which means 10% loss just from parasitic drain alone. But if the battery was twice the size, this loss would be only represent 5%.
This unit is perfect for those looking for high power output in a compact unit. If you need very high efficiency, it would be best to buy one with a smaller inverter. smaller the inverter, lower the standby consumption.
With solar panels & people reporting lower than expected outage, something as simple as setting one up on blacktop in high heat would have these panels running too hot and at a diminished capacity. Any small shading can hurt them pretty bad too - grass, one of the flaps of the 'kickstand case' blocking a small portion of the bottom. The opposite can happen in cold winter weather - temperatures at/below 0f will basically have panels overproducing - I've observed it with my own Ecoflow folding panel (160W) and several other rigid panels including a bigger 455W.

Gotta consider your own personal use cases because you may have several (and factor their real power demands by measuring your own devices' consumption).
At any rate, this isn't a bad way to have a legitimately useful amount of power on tap without immediately needing a gas engine and smelling like exhaust. This can power virtually any 120V power tool or appliance you can throw at it.

Ecoflow went a bit extreme with the delta 2 pairing a 1800/2400W inverter with a battery half the size at 1000wh. Making This is one of the lightest unit to be able to power ANY 110V household appliance.
Efficiency will not be high because you have a powerful inverter consuming lots of power even in standby. If you connect a 20W load to it, the total power draw will be close to 40w or more due to the inverter's standby consumption. And since the battery is half the size as industry standard, it translates into lower usable energy %.
The delta 2 has one of the best power to weight ratio. If you don't care about the weight go for the delta 2 max instead. Twice the capacity and twice the weight for $300 more
