The SCS-IV series microprocessor based charge controllers incorporate a breakthrough
in design with advanced pulse-width-modulation (PWM) battery charging operation.
Field proven PWM design for battery charging,
reduces water loss, extends battery life, and
allows more daily amp-hours into the battery
as compared to traditional “on-off” controllers.
New SMT circuit components allow for the
most compact assembly while offering the
highest quality and more features of
comparably priced PV controllers.
The Solar Commander Series IV-PV system
charge controller is for 12 volt solar electric
systems rated up to 24 amps charging and
intended primarily for RV applications, as well
as remote homes or cabins, house boats, campground & recreation facilities.
The attractive faceplate features four system status LED’s anda built-in LCD digital system
monitor which accurately monitors battery voltage and push button displays PV current.
A reverse polarity protection circuit features a reverse polarity red LED for PV or battery,
ensuring proper hook up.
Other Solar Commander models; (all 12V-24 amp withstandard specs) SCS-IV-L, includes a
load management-low voltage disconnect (LVD) circuit, prevents battery over-discharge
from operation of loads during extended overcast periods. Digital meter reads load current.
SCS-IV-R, includes a terminal connection to a remote current shunt, the digital meter
displays loads up to 500 amps (50mv-500a shunt required).
