I'm going to throw out a WAG of double.... and more batteries. But, of course we're talkin' about an AC fridge here. Now you're getting into off-grid HOME territory, which.... still can require a generator when you've got several straight days of rain and no sun.

Hey MR Wizard question on your BS2000 controller. Are you running all your panels throught it? 489 watts? I am doing calulation for what I want to set-up for my system and I am understanding that the BS limits is 340 watts. I was planning to use 3 Kyocera KD140SX, but was concerned at being at 420 watts. Am I readding something wrong with either the BS spec or is there something I am not following that you done? Are you pushing all this through the your BS controller? Thanks
Yes the Wizard is driving the BS2000 with 505 watts.
Controller clamps the amps at about 25.
Only ideal conditions will have the full wattage available.
Some power is not put into the battery (lost) when amps are limited.
The owner of the Rogue 3024 suggests that for a flat install up to 500 watts would be safe. I much prefer the Rogue for this size system than any other controller. If the system is going to be larger than 500 watts, I'd jump to the Tristar MPPT 60 amp unit.
