Morningstar Ecopulse Solar Controller – Metered 20A

Features

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.
