Introduction - opti-solar SC-50 Installation And Operation Manual

Introduction

The OPTI-Solar SC MPPT Series is a highly reliable solar battery charger and its most critical
feature is to maximize the harvest energy from the PV array into the battery by using the advanced
technology of Maximum Power Point Tracking (MPPT). The battery types that the OPTI-Solar
SC MPPT Series charge include Flooded Lead Acid (FLA), GEL ,AGM chemistries and LiFePo4
in the range of 12Vdc, 24Vdc, 36Vdc and 48Vdc nominal. The high efficiency of charging ability
can be accomplished through a 2 or 3 or 4-stage charging depending on the battery type. It is
built-in with the protection to ensure the battery without being overcharged or undercharged.
The wide range of the input array voltage and output battery voltage are well applied to the solar
system to allow system planner to produce the most of the solar energy. The input PV array of the
SC-50 MPPT and SC -80 MPPT may be wired in the range of 16~112Vdc nominal and the input
PV array of the SC -80X and SC -160X may be wired in the range of 16~192Vdc nominal. The
output battery voltage is accepted from 12 to 48Vdc nominal. After wiring up and operation, the
built-in intelligent data logging system can track the battery of charge (SOC) and the harvest
power produced over the days.
OPTI-Solar SC MPPT Series may not only well used in solar systems but also in wind or hybrid
systems. With respect to these systems, the 2 auxiliary relays can be programmed by constants
setting. The functions and programming of the relays helps to control the dump loads. Multiple
OPTI-Solar SC MPPT Series with cables (up to 16 units) can be connected in the larger power
systems. The controller with optional rectifier and braking unit for wind system is required to
control and stop the control from overload condition caused by over large wind speed.

Please carefully read through this manual and all the installation instruction and wiring before
beginning installation of your OPTI-Solar SC MPPT Series. The protection and installation
equipment should be complied with the local codes. The rated fuses, breakers and external light-
ning protection should be installed along with OPTI-Solar SC MPPT Series.
