If he's going to charge batteries why would he want a micro inverter? Then he would be going from DC to AC and then back to DC again. Unless he's feeding it into a fancy BMS that needs 120V AC to operate I don't see the point and even then is seems like way to much conversion.
I think your best bet would be something like an Outback Flexmax 60 or 80. They can be programmed to essenital be a Battery Management System and you get the advantage of MPPT with minimum conversion. And it would be lot cheaper than micro inverters feeding into a 120V AC fed BMS and then feeding your motor from that.
You can series your panels in sets of two or three to get your voltage where you need it and then gang them together in parallel. Outback is the vendor of choice for a lot of solar boats but there are certainly several good MPPT charge controller to choose from and I would strongly recommend going with an MPPT controller. Way better than PWM as they really optimize your array to get the most power possible to your motor when you running directly off the sun.
