Guest Joe90 Posted December 18, 2014 Share Posted December 18, 2014 Just wondered if anyone had made the change from a PWM controller to a MPPT one, ( a proper one not Ebay junk :D and any observations of doing so, thanks. Link to comment Share on other sites More sharing options...

Brian Kirby Posted December 18, 2014 Share Posted December 18, 2014 I think we're talking solar controllers for battery charging? Link to comment Share on other sites More sharing options...

Guest Joe90 Posted December 18, 2014 Share Posted December 18, 2014 peter - 2014-12-18 6:48 PM No idea what you're on about.?? That was the general idea, thought it best to post the question in such a way that anyone with any useful info would know what MPPT or PMW was referring to, I know about the differences in the technology, just wondered if anyone had made the switch from the cheaper PMW controllers to a true MPPT one and seen any advantage ;-) Link to comment Share on other sites More sharing options...
colin Posted December 18, 2014 Share Posted December 18, 2014 I guess you have googled it? Have you read this? http://solarcraft.net/articles/comparing-pwm-and-mppt-charge-controllers/ They recon 170w+ for MPPT to be effective. Link to comment Share on other sites More sharing options...
