Sizing
MPPT Charge Controllers
How
to Size a Solar Charge Controllers
Sizing
MPPT solar charge controllers by hand can be one of the more difficult
takes for a system designer. Unlike PWM or shunt controllers, many
MPPT controllers have the ability to down convert higher voltage PV
(solar panel) arrays to lower voltage battery banks. In order to do
the calculations, a few different NEC (national electric code) factors
are required. To explain this process is beyond the scope of this
article, but we can give a couple of web links to get you close. If
you are unsure of the correct controller for you, contact a solar
professional to help. Here are some links to manufacturers websites
that include sizing tools for their controllers.
