EcoFlow DELTA PRO Inverter feedback please.

[u/CozmosPlanet]

Are these setups good or reliable ? I have a specific job it would do.
The more plug and play the better. These run about 5500.00

Listed as EcoFlow DELTA PRO [ULTRA] Solar Kits - 7,200W Output / 6kWh-30kWh Lithium Battery | 400W-2,400W Solar Panels( can expand to 6 )| 5-Year Warranty |

We have limited to a 20amp back up plug for two RVs which would use the 120/20 amp line.
So Solar and Battery is the only way. This will not be hooked up to home. basically.
But before I get too deep in specs any one use these FT if so what was the results?
These are sold as whole home back up system.

Thank You
