Another 'thang... Praises and Hallelujah for the Xantrex C-40 controller. Mine is set at 24V; with bulk charge set to 28.5V (only 2v less than panels at max). This beast is the Jeep of controllers; it's rock solid reliable and survived a lightning strike. I tried an off-brand MPPT controller; the C-40 performed much much better in my humble opinion. The big seller of the MPPT controller is it's ability to convert excess voltage into amperage. I found that this actually is not that useful, the main problem not being use of energy when conditions are optimal but performance when conditions are cloudy. Because the C-40 does nothing period with the power under those conditions it is more efficient, delivering 100% of what power is comming in under low light conditions.
It's also cheaper; you can pick up a C-35 for less than a hundred dollars.
On the downside, you can't monitor your power remotely from the internet or get a composite image of power from all arrays in the area.
Oh well, life is suffering!
***Still can't figure out how to spell 'car' correctly***
