1. Overview
1.1 Information
Offgridtec MPPT Pro Duo charge controller apply to charge two batteries (shown as BATTI and BATT2 below) at the
same time in a solar system.
Flooded, LiFeP04, and Li-NiCoMn, which is suitable for RV, Camper, Boat, and so on. The starter battery (BATT2)
must be at the same voltage level as the board battery. The device automatically
starter battery (BATT2) and trickle charge the battery when the conditions are satisfied.
The controller adopts the advanced
and loss time,also fast track the maximum
the solar array under any conditions.
compared with PWM charging method.
When there is no manual operation for a long time, and the charging conditions cannot be reached, the controller will
turn to low-power mode, which reduces the loss and battery power waste to enhance the products life. The system
parameters are shown and set by LED/LCD or the MTI 1 remote (Accessory).
The AES control signal of the car refrigerator is built in the controller, which will supply the surplus solar power to the
refrigerator to avoid energy waste. The controller protection level is IP33, which is waterproof and dustproof. Multiple
protection features, including battery overcharge
protection of the PV and battery, which effectively ensured the solar system safety, stability, and lifetime.
Features
Max Power Point Tracking technology with ultra-fast tracking speed and the tracking efficiency is no less than 99.596
guaranteed.
Advanced MPPT control algorithm to minimize the MPP lost rate and lost time
The higher range of the MPP operation voltage to improve the PV module utilization.
Limited charging power & charging current auto control feature (BATTI).
•
High quality and the low failure rate of components(ST, Tl, and Infineon) to ensure the product life.
Digital circuit control of adaptive three-stage charging mode to enhance BATTI life.
• BATTI type can be set via LED/LCD.
The product runs into the low-power mode when there is no manual operation for long time, and charging conditions
are not satisfied (PV<5V).
10096 charging and discharging in the operation environmental temperature range.
• LED and LCD selectable.
AES control signal for car refrigerator to avoid energy waste.
Standard Modbus protocol, and RS485 (5V/200mA) communication port for the customer to expend the application
area.
@Life battery(BATTI)is the energystoragebatteryfor poweringthe householdloads in the off-gridsystem,which
supports Sealed, Gel, Flooded, LiFeP04, and Li-NiCoMn batteries (the controller can NOT recognize the system
voltage automatically).
@start battery (BATT2) i s the energystorage batterywhich usuallybuilt in the vehiclefor poweringthe systemsuch
as RV and Boat, and only supports lead-acid battery (the controller will recognize the system voltage automatically).
NOTE: the BATTI and BATT2 are at the same voltage
