Genasun is pretty much the agreed best engineered MPPT controller though they don't do higher current. They have varying options for battery chemistry and wattage. If genasun is what you use then you'll basically have to plan on one controller per panel which is great for reliability and redundancy but may not be so good on your pocket book. They also don't have digital volt/amp/watt outputs so you'll probably want to look at getting one. Genasun also offers a boost feature which allows a solar panel that outputs less than the battery voltage to charge the battery. Otherwise you'll have to ensure the panel voltage is greater than battery voltage and they won't start/stay charging in the morning or in the evening.
Just to talk numbers for a minute. My experience is that a 100 watt monocrystaline flexible panel mounted horizontally at a geographic latitude of 38° yields a max of 66 watts in the peek summer sun. I get about 4 or 5 amps peek charge current but only at peek sun. IIRC I get a cumulative ~900 watt-hours per day.

I'm looking to purchase 150 watt panels and control unit. What do you feel would be the best system? Requirements are minimal. Thanks for your help. Jim schwartz SEA YA !
