Twenty Five Amp MPPT Current Boosting Solar Charge Control.
(Maximum Power Point Tracking)
This is a Panel/Flush Mount
(For surface mount you need the optional enclosure or to make your own)
The model MPPT250HV is a 25 amp high performance current boosting solar control optimized for use with the Kaneka GSA211 60 watt solar panels and other systems utilizing High Voltage arrays. Through the use of advanced microprocessor control and a high efficiency power converter, power wasted in older PWM style solar controls is converted into higher charge current. The MPPT250HV allows for input voltage conversion. This increases the Maximum Power Point voltage and allows for higher boost current over wider operating conditions. You can charge a 12 volt battery from a high voltage solar panel. A high accuracy digital volt and amp meter displays battery voltage and charge current. An auxiliary 100 ma 13.8 volt trickle charger is provided to keep the engine/generator start battery fully charged. A 15 amp capacity low voltage disconnect protects the battery from over discharge conditions. Proper battery charging is maintained over a wide temperature range with the battery temperature sensor.
Battery
float voltage is accurately regulated. Night time battery discharge is eliminated through the use of a high efficiency Schottky diode. Maximum normalized input power to the MPPT250HV is 250 watts
Operation: When power is available from the solar panel, the MPPT250HV microprocessor measures and determines the optimum operating point of the solar panel to produce the highest charge current possible to the battery. There is no interaction between the MPPT250HV and other battery charging systems. The float voltage of the MPPT250HV is factory set to 14.1 volts. The float voltage is adjustable. When the battery voltage reaches the float voltage the red Float LED turns on. At this point, charge current to the battery will gradually diminish to maintain the float voltage. As soon a load is turned on, maximum charge current is applied to the battery. Temperature compensation adjusts the float voltage to properly charge the battery over a wide temperature range. When the battery is warm the float voltage will drop and when the battery is cold the float voltage will rise. The MPPT250HV is well suited for flooded, deep cycle and gel type batteries. A low voltage disconnect is included to protect the battery from excessive discharge by automatically turning off a load, such as lights that may have been left on. Load is disconnected when the battery voltage is 12.0 volts or lower. When the batteries are recharged to 12.6 volts the low voltage disconnect reconnects the load. The yellow LED on the face of the MPPT250HV is lit when the load is connected. Operation of the low voltage disconnect is fully automatic. Maximum low voltage disconnect load current is 15 amps. Do not connect the low voltage disconnect to inverters.
