Key Features and Benefits
- Maximum power point tracking (MPPT) optimally matches the solar array to the battery—no wasted PV electricity.
- Use of high voltage modules – In addition to 12V crystalline modules,
enables use of high voltage modules for off-grid battery charging. - Converts 36V or 24V arrays for use with either a 24V or 12V battery.
- Automatic Lighting Control – four programmable timer sequences for PV lighting applications using MSView.
- Extensive electronic protections include short-circuit, over-current and reverse polarity to ensure the controller will not be damaged by wiring mistakes or overloads.
