In this video I put together an MPPT solar charge controller made by MakeSkyBlue.
Items used in this video:
MakeSkyBlue 20A MPPT Solar Charge Controller Kit: http://s.click.aliexpress.com/e/vrewmLq
Vici VC99 Multimeter: https://ebay.to/2ucz5Xd
Uni-T UT211B Clamp Meter: https://ebay.to/2T9lUk0
You can buy a fully built MakeSkyBlue solar charge controller if you like, but where is the fun in that?
