blazie’s right… you’re never gonna charge up 450Ah with 30w of panel. You need a rightly sized system and it seems (maybe im wrong) your battery capacity is a little over the top for what you want to do. Unless of course you bought them as an investment and looking to do more. You need to keep your batteries from discharging below 20% (worst worst case) and they should be given regular trickle charges when you aren’t using them…
