Why Morningstar Regulators?
The battery can represent 40% of a system’s cost and a much as 80% of the lifetime costs. A controller may only be 5% of the cost but its ability to protect and increase battery life is crucial.
Due to protections in the software and the quality and ratings of the hardware selected, product failure rate is less than 0.15%. Morningstar typically over-sizes components to leave a margin of error for users.
Selection of Components
Morningstar sources the highest quality parts which promotes proven reliability and performance
Short thermal paths and no fans blowing across circuit boards prevent dust, insects and corrosion.
Fewer components equal lower failure. Intelligent board layouts offer better signal routing, trace lengths, inductance, etc.
25 Years of Experience
Morningstar leverages years of power electronics industry expertise to create highly reliable products with peak performance.
The Morningstar software team develops software architecture that extracts the maximum performance possible from the battery. This optimizes the cost to performance ratio and allows quick power electronics control; even in the smaller controller and inverters

Extended battery life
PWM series battery charging with temperatue compensation. Sealed/flooded battery select.
Epoxy encapsulation, marine rated terminals and anodised aluminium case provides environmental protection.
SunKeeperTwo battery charging
Solar charge current is shared between two batteries based on a user selectable priority. When one battery is fully charged, all of the charge current flows to the other battery.
Epoxy encapsulation protects the controller against dust and high humidity. Extensive electronic protections, including short circuit,over current and reverse polarity, ensure that the controller will not be damaged by wiring mistakes or overloads.
Controler paramters may be adjusted ising the DIP switch on the controller. Further customisation is enabled by connecting to a personal computer and using Morningstars PC software.

Morningstar MPPT Solar Regulators
Morningstar SunSaver MPPT
This range of MPPT solar controllers enables the use of high voltage and thin film modules for off-grid battery charging for both 12V and 24V applications. These solar controllers allow the user to take advantage of the lower prices of the higher wattage panels, typically used in the on-grid market, to make larger arrays of up to 400W
NEW ProStar MPPT
The new Prostar MPPT 25A regulator maximise energy harvest in solar panels up to 350W when charging a 12V battery or 700W for 24V. They are suitable for lead acid, ni-cad and the latest Lithium batteries. This model is particularly recommended when using a grid type 24V solar panel to charge a 12V battery.
30A, 45A, 60A in 12V, 24V or 48V)
Maximises energy harvest
Better peak power tracking than other MPPT controllers.
Very high efficiency
the industry’s highest peak efficiency of 99% for off-grid charge controllers
Extensive networking & Communications
Enables system monitoring, data logging and adjustability. On board ethernet included on the TS-MPPT-60.v
Maximum power point trakcing provides an increase of amps from the solar array into the battery.
Use of high voltage module
In addition to 12 volt crystalline modules, enables the use of high voltage and thin film modules for off-gird battery charging.
harvests the power from the peak power point of the solar array, converts the power down to battery voltage, and boosts charging current in the process.
