Models SR7 and SR7C are advanced pro d u c t s
designed for use in small size solar electric
systems, typically used for re c reational vehicles,
w i reless-local-loop applications, small rural
electrification and intro d u c t o ry level PV
systems. The controllers solid state design
p rovides a cost-effective migration of
technology for users and systems curre n t l y
using relay based or traditional “on/off”
c o n t rollers. The SR series features a
pulse-width-modulation circuit, which
positively ensures a well-controlled bulk
and then taper charge of the battery at the
regulated voltage. This unique design
without the micro p rocessor finally brings to the first-time user a PWM product at a price,
which is extremely attractive. The SR7C is a charge-only model and SR7 is supplied with a
LVD as standard. Controller status is displayed on three LEDs.
