Introduction
The AIMS MPPT+ 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 advanced technology of Maximum
Power Point Tracking (MPPT). The battery types that the AIMS MPPT+ will charge include Flooded
Lead Acid (FLA), GEL , AGM chemistries 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 charger
depending on the battery type. It was designed with built-in protection circuitry to ensure batteries will
not be over or under charged.
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
SCC40MPPT and SCC80MPPT 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 state of charge (SOC) and the harvest power produced over time.
AIMS MPPT+ may not only be 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 help to control the dump loads. Multiple AIMS MPPT+ with cables (up to
16 units) can be connected in 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
excessively high wind speeds.
.
Please carefully read through this manual and all the installation instructions and wiring before
beginning installation of your AIMS MPPT+. The protection and installation equipment should comply
with local codes. The rated fuses, breakers and external lightning protection should be installed along
with AIMS MPPT+.
