Morningstar ProStar PS-30M Charge Controller

Morningstar's sophisticated ProStar PS-30M solar charge controller incorporates constant voltage PWM (pulse width modulation) to make maximum use of valuable PV power. It features automatic equalization, temperature compensation, and very high efficiency. This controller can be used on 12V and 24V systems using either sealed, gel, or flooded lead-acid batteries. Front panel LEDs indicate when the batteries are being charged, as well as the relative state of charge. LCD displays battery voltage, PV charging current, and load current.

Safety features include reverse polarity protection on input and output, automatic high/low voltage disconnect, and automatic short circuit disconnect. Low voltage disconnect (LVD) is current-compensated to prevent false disconnect when the battery is heavily loaded.
