Collection: Solar charge controllers

Victron Energy solar charge controllers for 12V and 24V systems: BlueSolar PWM-Light, PWM-LCD&USB with display and programmable PWM-Pro from 5A to 20A, with the wiring and programming accessories.

A charge controller is sized on the short-circuit current of the array with a 25% margin: a 100W panel at 12V asks for about 10A. PWM is the economical choice when panel voltage is close to battery voltage; for higher voltage strings, or to pull every watt out of an overcast day, move to MPPT.

Every model carries charge profiles for lithium, AGM, gel and lead-acid and protection against reverse polarity and overheating. Suited to motorhomes, boats, huts and small off-grid systems.
