60A MPPT 600V charge controller / regulator with a DC transfer switch for large solar PV systems, or retro-fitting existing grid-tie systems. Advanced TrakStar Technology for maximum power point tracking efficiency and high voltage capacity.

SPECIAL NOTICE : If you are purchasing this part for a self build project, please see our terms & conditions. FULFILLED BY PHOTONIC UNIVERSE : This product is fulfilled by Photonic Universe, our Solar partner.



As an official distribution partner of Morningstar products across the globe, we are proud to offer solar charge controllers from this world-leading supplier. Innovative design from years of dedicated research and superior build quality enable these top-of-the-range solar charge controllers to extend battery capacity and life, maximise energy production, and consistently achieve high performance standards.

This high voltage Morningstar TriStarTM 60A MPPT 600V charge controller with DC transfer switch is suitable for large off-grid solar power systems with high input voltages, or retro-fitting existing grid-tie systems with a battery backup component. It uses TrakStar TechnologyTM, which provides the very best automatic power point tracking by sweeping the I-V curve faster than any other MPPT controller on the market, and maximising the energy harvest of the off-grid system. With 97.9% peak efficiency, low self-consumption and subsequently less power losses through the off-grid system, this MPPT controller guarantees an excellent return on investment.

Due to its high voltage capabilities, this unique controller can be used with new grid-tie PV installations or added to existing grid-tie PV systems, to allow storage of excess energy in a back-up battery bank. This can be achieved without changing the existing PV array configuration, and can even enable incremental adding of solar panels to an array with no string sizing issues and Voc voltages upto 525 Voc. This action allows fewer combined circuits and lower current for long wire runs from the array to the controller.

The DC transfer switch and enhanced wiring disconnect box allows 60A continuous battery current from your solar array to be stored in a battery bank or to be manually switched to the grid-tie inverter.

Other key features include:

  • High voltage capacity, with a maximum input voltage of 600V that reduces voltage drop and wire costs
  • Used in conjunction with new or existing grid-tie power systems to allow alternative battery storage
  • Extremely high reliability, with no cooling fans or moving parts and a robust thermal design for high operating temperatures
  • Incredibly high peak efficiency of 97.9% - an outstanding feat within the solar industry
  • First 600V PV controller to offer extensive communication capabilities with internet access for custom settings, data logging and remote monitoring


The controller is pre-set to protect 48V batteries whilst charging them, providing automatic cut off to prevent over-charging and deep discharge. It is also programmable to set for 24V, 36V and 60V battery banks.

It comes with a full range of electronic protection functions: overload, short circuit, high voltage, reverse polarity, high temperature, lightning and transient surges, reverse current at night.

This controller can work with sealed, gel and flooded batteries.

The maximum allowed input solar power for this controller is: 3200W (48V)

The controller can also be connected to the TriStar remote meter with 30m extension cable (sold separately) to view detailed charging parameters and remotely monitor your system.
