Prostar 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.
PS models 12, 20 and 30A
are as listed above. MC models include conformal coating, digital
meter and ‘on/off’ switch. Digital meter displays battery voltage, PV
current and load current.
The ProStar Remote
Temperature Probe (RTP)
provides very accurate battery charging in solar systems where the
controller and the battery
experience different
ambient temperatures.
Since the ProStar
charging is temperature compensated, the RTP allows the temperature
to be measured accurately at the battery.
The RTP is easily
installed by soldering two wires to the ProStar circuit board. The
ProStar will not operate with any other temperature probe from
another supplier. Also, the RTP may only be used for ProStars
produced after May, 2001.
For maximum environmental protection, the probe is encapsulated in
epoxy inside a stainless steel housing.

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 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.
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%
