According to the product dedscription, PowMr's 10kw hybrid inverter is more versatile in that it can be set to charge and discharge the batteries, meaning you can maximise the use of solar energy.
this split phase inverter (sunsmart 10k)can put out 120/240v, or this 5kw inverter supports parallel connection for 240v split phase.
I was recently looking for information on split-phase inverters and found this explanation of split-phase inverters, which is quite detailed, so I hope it helps...
