Morningstar EcoPulse Solar Charge Controller – 20 Amp – The EcoPulse is a pulse width modulation (PWM) solar charge controller within Morningstar’s Essential Series™ of products which provides essential off-grid battery regulation functions. This controller is easy to use, and designed 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.
Key Features & Benefits:
- 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.
