MPPT solar charger

Friday, October 14th, 2016

Lukas Fässler has designed and built an MPPT solar charger: One of my main goals with this design is to archieve very low standby current, somewhere in the tens of microamps. The basis for this is a low-power buck on the basis of a Texas TPS62120 where the microcontroller can...

Scalable 12V solar power system and battery charge controller

Tuesday, May 22nd, 2012

Squonk writes about this scalable solar charger he's located: An unconventional, scalable high efficiency 12V solar power system and battery charge controller with low voltage cutout to protect the battery. (ideal for systems of 50W or less). The most common solar charger consists of a Schottky diode to prevent the...
