40 lbs is a light weight high frequency inverter, but it says 2x surge for 5 seconds, so should start a 2000W motor.
(correction from what I originally wrote: “so don’t expect surge current to start anything larger than 1000W motor.”)
120V, you can add one or two for 120/240V or 3-phase.

To make sure you don’t screw anything up, understand how Voc of PV panels is affected by cold temperature and plan your series/parallel strings so you never exceed the 250V max spec of inverter.

Depending on the PV panel specs, don’t know if 5 in series is Ok (SolarQueen just indicated probably, but do the math)
Otherwise, could be 3s2p into one MPPT input, 4s1p into the other.

Got a data sheet for the panels?

I like that the inverter is “batteries optional”, gives you economical possibilities.
