For over 20 years Morningstar has been supplying solar charge controllers to regulate batteries in off-grid residential applications. Morningstar controllers dissipate heat without using fans or other moving parts that are noisy and prone to failure. The following additional capabilities and features make Morningstar the ideal choice to regulate power in cabins, remote homes, and other off-grid dwellings:
Auto recovery without fuses
Wide operating temperatures
Transient surge protection
Multi-stage battery charging
Ease of installation

Maximum Power Point Tracking (MPPT) technology to extract every bit of electricity possible from the solar source, by converting extra voltage into useful amperage.
Morningstar MPPT controllers have industry-leading TrackStar technology on-board for that purpose
Full programming to enable a high-level of system customization. Faceplate mounted timer and test buttons allow for easy system/setting configuration for a variety of uses
Load and lighting control for easy integration in lighting systems. Dusk and Pre-dawn settings optimize usable lighting during high-use periods while minimizing power consumption during unoccupied periods.
Industry-leading technical support from a US-based company
Easy system integration with generator control
Standard serial and optional Ethernet capabilities
Remote access and control
Data logging to record charging/load Amp-hours and alarm/fault notifications
Full programming to enable a high-level of system customization
Built-in communications and diagnostics capabilities
Temperature charging protection and advanced charging algorithms to protect expensive storage batteries, both lead-acid and advanced types including lithium. Dead battery recovery feature helps reduce system down-time
Designed for trouble-free operation in extreme temperature and weather conditions. Epoxy-encapsulated circuit boards and 60C ambient temperature ratings to handle harsh environments including tropical, coastal and arid regions. Weatherized construction; no cooling fans to fail
Simple, out-of-the-box operation and easy installation
Safety features built-in, including alarm/fault notifications, mis-wiring protection, lightning protection
Morningstar’s TriStar MPPT 600V charge controller leverages Morningstar’s innovative TrakStar™ MPPT technology and our 20+ years of power electronics engineering excellence, to enable the widest input operating voltage range available from a solar array, wind turbine or hydro input.
Proven over two decades, the “legend that keeps improving.” An advanced controller for systems up to 1,100W. Available in 25 and 40 amp versions for 12 and 24 Volt batteries. Includes lighting control.
Morningstar’s TriStar™ is a three-function controller that provides reliable solar battery charging, load control or diversion regulation. It is rated at 45 or 60 amps, both at 12-48 volts, and has an optional meter, remote meter and remote temperature sensor.
Legendary ProStar design and performance for mid-range lighting systems in areas with consistent sunlight and minimal shading. Available in 15 and 30 amp versions for 12 and 24 Volt batteries. Includes lighting control.
Morningstar SunSaver Duo ™ is an advanced PWM two battery controller for RVs, caravans, boats and cottages.
How do I choose if I need MPPT or PWM-type solar controllers?
This is not a quality difference, but a function of prevalent solar conditions and location considerations.
Because MPPT (maximum power point tracking) controllers convert extra solar electricity voltage into useable electricity, they are ideal for areas where seasonal, weather and shading conditions cause wide variations in solar “harvesting.” Morningstar’s proprietary TrackStar™ MPPT technology is considered the industry’s performance standard. Because of their additional circuitry on-board, MPPT controllers are also more complex and expensive.
PWM (pulse-width modulation) controllers are the right choice for systems using 36 or 72-cell solar-panels in locations 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 cost effective as a result.
All Morningstar charge controllers, regardless of their technology or design, built to one industry-leading quality standard. They all have “over-spec’d” components, incorporate advanced electronic design and thermal engineering, and have no cooling fans to fail—unlike all the in-kind competition. Because of this, over four million Morningstars have been sold since 1993 and are the first choice for leading solar installers in mission-critical installations around the globe.
