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).

In MPPT Bulk it seeks Vmp. In PWM mode in Absorption and Float it lets go of Vmp and does "on demand" with voltage varying (not constant) The voltage appears to go higher than Vmp down the knee and back up the knee if demand increases. Actually it is turning on and off (PWM) with durations varying.
