READ ALL INSTRUCTIONS PRIOR TO INSTALLING OR USING THIS EQUIPMENT.
SAFETY INSTRUCTIONS:
Refer installation and service to qualified service personnel. Incorrect
installation may result in risk of fire. Remove all sources of electrical power, photovoltaic and battery
before servicing this equipment. Never charge a frozen battery. Warning! Batteries produce explosive
gasses. Install batteries in a well ventilated area. Follow battery manufacturer’s maintenance and charging
recommendations. Install properly rated fuses as required. Do not connect controller to generators or
alternators. Caution, high voltages may be present. Do not disturb any components on the circuit board.
DESCRIPTION:
The model MPPT500 is a high performance current boosting solar control. Through the
use of advanced microprocessor control and high efficiency power converter, power wasted in older PWM
style solar controls is converted into higher battery charge current. The MPPT500 allows for input voltage
conversion. This increases the Maximum Power Point voltage of the solar panel and allows for higher boost
current over wider operating conditions.
Model MPP500HV operating efficiency has been optimized for
48 volt nominal PV input voltage.
A high accuracy digital volt and amp meter displays battery voltage, photovoltaic current and
battery charge current. 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 reverse flow diode. Maximum input power to the MPPT500 is 500 watts.
Maximum photovoltaic input voltage is 100 VDC open circuit.
OPERATION:
During operation the MPPT500 may feel warm. Operation of the MPPT500 is fully
automatic. No adjustments are required for most installations. When power is available from the solar
panel, the MPPT500 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
MPPT500 and other battery charging systems.
The float voltage of the MPPT500 is calibrated to 14.1 volts. When the battery voltage reaches
14.1 volts the red Float LED turns on. At this point, charge current to the battery will gradually diminish to
maintain the 14.1 float voltage. As soon as 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. MPPT500 is well suited for flooded, deep cycle and gel type batteries.
SYSTEM PLANNING:
Carefully plan your installation. Determine fuse ratings, wire size. Install the
MPPT500 near the battery bank. Avoid installing the controller in wet, damp or small confined locations.
Do not install the MPPT500 in direct sunlight. Use short direct wiring. Install the controller in accordance
with state, local and national electrical codes. Securely fasten the controller to a wall or other suitable
structure. Provide support for all wiring. Place the battery temperature sensor on or near the battery. Install
properly rated fuses.
WIRING:
Remove the four # 6 black Phillips screws to gain access to the interior of theMPPT500.Install
the two wire bushings in the wire conduit holes if conduit is not used. Do not touch or disturb any
components of the MPPT500. Use high quality stranded wire only. Solid wire is not recommended. The
MPPT500 wire connector will accept up to # 2 AWG wire. A short length of # 2 wire may be spliced into a
larger size wire for long wire runs. Install the battery fuse within 9” of the battery. See wiring diagram (last
page) for more details. Make certain no loose strands of wire fall onto the MPPT500 circuit board or
enclosure.
