EcoPulse Solar Controller – Metered

The NEW EcoPulse™ is now available and shipping from our warehouses. The EcoPulse is a pulse width modulation (PWM) solar charge controller within the Morningstar Essential Series™ which provides essential off-grid battery regulation functions. This controller is easy to use and was developed for residential and leisure consumer applications. Metered and non-metered versions of this product are available at 10, 20, and 30 amp charge ratings for 12 and 24 volt battery systems. This controller is not sold in the USA or Canada.

  • High Reliability – conformally coated circuit board and corrosion resistant terminals.
  • Robust Thermal Design – extruded aluminum heatsink dissipates heat quickly without using cooling fans.
  • Durable Casing – high strength polycarbonate case.
  • LED Fault Indications – alert when short circuit, over current, high voltage, and other error conditions take place.
  • Automatic Solar Based Lighting Control – field adjustable dusk ‘til dawn setting.
  • Adjustable Charge Settings – seven presets and a custom setting can be set via DIP Switches or by the meter display buttons.
  • Adjustable Load Control – load control can be adjusted via meter display.
  • Optional Meter – multi-lingual interface with scroll buttons to adjust the settings and display metrics.
