Charge Controller Family Guide

Morningstar’s charge controller family is made up of ten product lines in two series:
  • Professional – Legendary reliability and performance make Morningstar Professional Series the leading charge controller brand for mission-critical off-grid solar powering applications—and the first choice of leading system designers and installers for over a quarter-century
  • Essential – Morningstar technology, quality and reliability that’s affordable for small residential and other applications, with more basic features. Available outside North America in selected international markets (contact an authorized distributor for information)
Solar charge controllers use one of two technologies: Maximum Power Point Tracking (MPPT) or Pulse Width Modulation (PWM)
MPPT technology
(Maximum Power Point Tracking)
Can convert all the solar electricity voltage possible into useable electricity. MPPT's maximum conversion efficiency is ideal for areas where seasonal, weather and shading conditions cause wide variations in solar “harvesting.” Because of additional circuitry, MPPT is more complex and expensive. Morningstar TrackStar™ MPPT technology is the industry’s reference standard
PWM technology
(Pulse-Width Modulation)
Used in places with consistent sunlight, minimal shading and no physical space limitations—such as at the top of light poles, for example. PWM controllers are simpler and more cost effective, ideal for use in systems where extracting every last watt of electricity possible from a PV array is not a concern
Legendary reliability and performance make Morningstar Professional Series the leading charge controller brand for mission-critical off-grid solar powering applications—and the first choice of leading system designers and installers for over a quarter-century
