How is a full-inverter heat pump different from a standard one?

A standard heat pump runs its compressor at one fixed speed, switching on and off to hold temperature. The MI650 varies compressor speed from 20% to 100%, so it runs longer at lower output, which is where most of the efficiency and quiet come from.

What does the COP of about 8 mean?

Coefficient of Performance is heat moved per unit of electricity used. Moov rates the MI650 at roughly 8 on average versus 4 or 5 for conventional heat pumps, meaning more heat per kilowatt-hour, though real numbers depend on air and water temperature.

Will it trip my breaker?

The soft starter limits the initial current surge, so the MI650 draws less at startup than a fixed-speed pump of the same size. That can let it run on a smaller breaker, but the circuit still has to be sized for the unit's rated running current.

How loud is it really?

Moov claims as low as 48 dB at 3 meters, which is close to normal conversation. Inverter units are quietest at low speed, so expect more sound when the compressor runs near 100%.

What size pool is 65,000 BTU good for?

BTU should be matched to water volume, surface area and climate. 65,000 BTU suits a large pool or a spa plus pool combination; a smaller pool may be overpowered and a very large one may need more capacity.

Does it heat and cool?

It is a heat pump, so it moves heat rather than generating it, and reversible models can also chill water. Check the specific model's mode list before buying if you want cooling.
