Best charge controllers..
What are the best charge controllers out there? Mostly looking at Mppt. Reading about some doing flaky things, or not charging properly (bad electrical design).

So.. PWM, with its switching the higher voltage on and off extends battery life and removes sulfation, while MPPT does not? MPPT results in shorter battery life?
Is there an MPPT charge controller with a boost? Mode? Boost mode is for cleaning off sulfate?
During absorption it is in Constant Voltage mode. It can still deliver higher current that the max current of the panel which is the drawback of a PWM controller. You only get the max current that the panel provides with a PWM controller.
An MPPT controller is essentially just a DC to DC converter. If you have panels wired at 100V putting out 10A for a 1000W, trust me, you will be putting in more than 10A in absorption mode.
