ProStar Mid-Range Photovoltaic Controllers

USING ADVANCED TECHNOLOGY FOR HIGH RELIABILITY,
LOW COST PWM BATTERY CHARGING

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. The PS15M-48 is 48v only.
Prevents reverse current. Series switching prevents battery from discharging ot night through the array.
Temperature compensation. Corrected setpoints 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.
Mannual disconnect. (Option) Button will instantly disconnect all PV and load connections. Same button serves as a mannual disconnect.
Battery charge LED's. Three LED's indicate relativebattery 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%.

SunSaver Photovoltaic Controllers

Sunsaver is a small solid state controller with encapsulated circuit board.

Uses only 3.2 ma to operate
6 or 10 Amp capacity
LED's for charging and LVD indication
Optional load low voltage disconnect

SUNSAVER QUALITY, VALUE and RELIABILITY

Sunsaver’s battery charging design closely copies the ProStar’s advanced charging algorithm. The series PWM algorithm is very stable, yet responds instantly to changing conditions. Maximum charging efficiency is ensured, with minimum stress on the battery. The constant voltage PWM charging is a proven advancement compared to the common on/off PV regulators.
