I got LG panels from E-marine in Ft Lauderdale and have been really happy with them. The catch is there's no warranty for mobile installations. I priced SunPower panels and they were really good and really pricey. I could replace the LG panels three times for the price
of a SunPower, but they did warranty a mobile installation
. I had only 65 inches of space on my hard top and all brands but LG and SunPower had only 76 inch panels for anything over 300 watts.
Watch out for the for the Morningstar Tristar MPPT
controllers. They have a feature called float skip which is supposed to help the batteries
recover from a deep discharge by never going into float the next day but staying at absorption voltage as long as it can. The default trigger for this feature is supposed to be 11.5v, but all of the preprogrammed configurations on mine had the setting programmed for 12.5v. This was not an issue when I installed them in late December, but by the first of April my batteries
were toast from overcharging. There is another problem that happens when you are plugged into shore power
. The controller senses night when there is no output from the solar panels
and even if the batteries are on float from a charger
it will start another charge cycle forcing the batteries to absorption voltage for whatever their state of charge. The only way I found around this was to create a custom charging
profile for when I'm plugged in that has absorption set to the same voltage as the float voltage. I don't know what the charging
profiles are for their lower end controllers but you would think they would have better profiles and programming in their flagship line. My recommendation is to get the LG panels but find another controller brand.
