The CD 300 pump controller is designed to connect solar modules to Kyocera Solar’s SD series submersible diaphragm pumps.
The controller provides current or voltage boosting combined with true Maximum Power Point Tracking (MPPT) of the solar
modules. The pump controller’s microprocessor, using true MPPT, constantly monitors the incoming solar power and boosts
current or voltage to operate the solar modules at their peak power point and maximize pump output. The controller is entirely
self configuring and requires no setup or adjustment by the user to ensure proper operation.
The CD 300 controller will accommodate one or two 36-cell modules in series. Other combinations of modules can be used as long
as the total Open Circuit Voltage (VOC) does not exceed 50 Volts. Modules can be wired in parallel to maximize daily water
production. Highest efficiencies (94-98%) will be attained when the solar modules are wired in series for operation between
30-42 Volts. However, single modules, such as a KC120, can also be used, maintaining controller efficiencies over 92%.
In addition to solar modules, the controller will also operate the pump using 12 or 24 Volt battery banks as a power source. The CD
300 controller will also work with any permanent magnet positive displacement pump rated for 30 Volts with 10 Amps maximum
current draw.
The controller’s unique design simplifies control and troubleshooting of pumping. Inputs are provided for remote switches and
Kyocera Solar’s unique water level sensor. Indicators provide convenient information about voltages, switch and sensor status, and
overload conditions.
Kyocera Solar’s newly designed pump controller is user friendly. It is designed to provide maximum power under varying conditions
and requires no programming by the user. We are proud to introduce the Kyocera Solar line of pump controllers and are confident
you will be satisfied.
