Looking over your selections, I would strongly recommend against the HF inverter, it specifically states "not for marine
use." I'd look for a trusted brand rated for marine
use and with a very low current
draw on stby.
The solar panels look like a great deal, they'll actually provide closer to 46-48 amps in direct sunlight, and more than 30 amps most of the time.
The solar controller - I have no experience with that model, the specs on it look pretty good. On one hand, I've recommended a well known brand like the Morningstar MPPT 60 amp controller, but by the time you get the unit and remote
display, you've spent about $660, which is $425 more than the other one, and I've been pleasantly surprised by a $100 controller, so it's up to you. I'd verify the front panel readings with a good DMM in terms of input voltage/current and output voltage/current and if the numbers make sense (watts in = watts out x 97%) then it's doing what it's supposed to do.
However, if you feel it's not really an MPPT controller or not as efficient as advertised, don't hesitate to start the refund process and send it back, Ebay is getting very good at protecting customers these days.
