Review from a similar MPPT in Solar Charge Controllers

no fault of etrailer.com, but instead 100% the GO Power MPPT product,
seems there is a broad range of specifications WITHIN "their PUBLISHED specifications".
the MPPT states capable of 150 voc (this is still on their pdf however it is only a SURGE rating not a REAL RATING) then their fine print states "100 voc dc" (see link below "for proof" (this is a wide range by dropping 50 voc dc) and array power limited to 1040watts (as stated on my original pdf from Go Power) at 12 vdc on before limiting occurs. So a SIX panel array of 100 watts each with a volt open of 22.5volts in series .....means 6X22.5= 135 voc.(should be good to go right)..can't do it.... so a max of 6 panels 6x22.5vdc VOC = 135 voc dc BUT can't do it ...blows the unit apart.....and needs warranty repair.....which I did....so it will not handle THEIR RATED SPECIFICATIONS! you will need to be AT 100voc on your design specs which is not stated anywhere
which states a MAXIMUM of 100 voc so that's only 4 100watt panels at 22.5 voc dc which of course is only 400 watts input power that this unit will handle... I'd challenge you to double check and triple check ALL OF YOUR PANEL specs before purchasing this unit as I've wrapped my brain around it and don't see how ANY modern PANELS will not achieve MORE POWER than this MPPT charger will handle unless your on 48V ONLY system..
to be short and simple I looked at perfectly matching 4 of these panels from reynogy for 200 watts each and guess what they have a VOC rating of 27 voc each so in series they are 108 voc so that should work due to being in a real world solution near 100 voc rating of this MPPT controller as most panels never really achieve 100% power in the real world....
Before dealing with me on tech support this MPPT controller was rated at 1040 watts ON THEIR PDF ... once I proved to them that IT WOULD NEVER ALLOW IT.... now their tech support documents state 800 watts and in reality it might be able to handle 800 watts (IF PERFECTLY MATCHED PANELS ARE INSTALLED) but I wouldn't rely on it..I changed out the controller to a victron controller and I keep this one because I can't return it and I might want to ADD portable solar panels some day which I AM SURE it will handle.
