General Information
2.1 Overview
The RENOGY MPPT series controller is suitable for off-grid solar applications. It
protects the battery from being over-charged by the solar modules and over-
discharged by the loads. The controller features a smart tracking algorithm that
maximizes the energy from the solar PV module(s) and charge the battery. At the
same time, the low voltage disconnect function (LVD) will prevent the battery
from over discharging.
The MPPT40CC controller charging process has been optimized for long battery
life and improved system performance. The comprehensive self-diagnostics and
electronic protection functions can prevent damage from installation mistakes or
system faults. In addition, the MPPT40CC controller has a RJ45 interface to
allow communication with a meter for remote monitoring. The MPPT40CC has
the following features:
•
12V / 24V auto recognition.
•
Advanced maximum power point tracking technology to optimize the use
of the PV
system.
•
Peak conversion efficiency of 97 %, high Tracking efficiency of 99%.
•
Fast sweeping of the entire I-V curve, several seconds tracking speed.
•
Widely used, automatic recognition of day and night.
•
Timer function with 1-15 hour option for streetlight.
•
Unique dual timer function; enhance the flexibility lighting systems.
•
Sealed, Gel and Flooded battery option.
•
Adopting temperature compensation and correcting the charging and
discharging
parameters automatically, improving battery lifetime.
•
Electronic protection: Overcharging, over-discharging, overload, and short
circuit.
•
Reverse protection: Any combination of solar module and battery, without
causing
damage to any component.
•
Excellent thermal design and natural air-cooling.
•
RJ45 interface for use with the remote meter MT-5, convenient to check
operating parameters of
controllers.
Although the MPPT40CC controller is very simple to configure and use, please
take your time to read the operator's manual and become familiar with the
controller. This will help you make full use of all the functions and improve your
solar PV system.
