ProStar Mid-Range Photovoltaic Controllers

SUPERIOR SERIES SWITCHING

Designed by experienced PV system engineers, ProStar’s series design provides many advantages compared to shunt controllers. Series regulations reduces FET heating and lowers voltage stress on the power FETs. A series configuration also improves protection against lightning surges and reduces switching noise. The series design improves charging accuracy. In PWM, series switching becomes self-correcting for temperature and system voltage drops.

FEATURES

• Automatic voltage select Provides flexibility for either 12V or 24V systems, Processor automatically configures for correct system voltage.
• Prevents reverse current. Series switching prevents battery from discharging at night through the array.
• Temperature compensation. Corrected set points referenced to ambient temperature
• Field selectable. Electronic selection of either a sealed or flooded battery. Two sets of optimized controls parameters are built into the processor
• PWM battery charging. Series PWM design will reduce heating and system voltage drops. Precise finishing charge under all system conditions
• Reverse polarity protected. Full electronic protection against any sequence of reversed wire connection
• Battery sense. Eliminates voltage drops for more accurate control. Automatic default to battery connections if sense is not connected.
• Low voltage disconnect. Low resistance FET's will handle load starting currents up to 10 times rating. Electronic short-circuit protections. LVD is current compensated with no parasitic loss.
• Manuel disconnect. (Option) Button will instantly disconnect all PV and load connections. Same button serves as a manual disconnect.
• Battery charge LED's. Three LED's indicate relative battery state-of-charge. All LED's are pulsed to minimize parasitic loads

LCD meter. (Option) Three-digit display with reflective foil for easy readability. Wide temperature range from -30 to +85 deg C. Values displayed are accurate by 1 - 2%.
