Overview
The remote meter is an accessory that is compatible with the Offgridtec MPPT PRO DUO series controller. It can monitor the running data and working status of the controller via the remote meter. The remote meter can browse the controller’s parameters, set the battery type and temperature unit, and clean the generated energy. It is suitable for RV, Camper, Boat, and so on.
Features
- Automatically identify and display the type, model and relevant parameter data of controllers;
- Real-time display the operational data and working status of the connected devices in digital, graphics and textual forms by a large-screen multifunction LCD;
- Three touch buttons are easy and quick to operate.
- Both data and power flowing on the same lead, no need for external power;
- It can browse the controller’s parameters, set the battery type and temperature unit, and clean the generated energy.
- Real-time display of failure information of the connected devices;
- Longer communication distance based on RS485.
Installation
Base of Remote Meter
Wall installation steps
Step1:
Locate and drill screw holes based on the Frame Mounting dimension of the
base, and erect the plastic expansion bolts;
Step 2:
Use four PA4.2×32 self-tapping screws to fix the Frame;
Step 3:
Remove the decorative shell.
Step 4:
Use four M4×8 pan head screws to mount MT11 Surface on the Frame;
Step 5:
Install the decorative shell.
Steps of surface mounting
Step 1:
Locate and drill screw holes based on the installation size of the Surface.
Step 2:
Remove the decorative shell
Step 3:
Use four M4×8 cross recessed pan head screws with M4 nuts to mount MT11
Surface onto the panel.
Step 4:
Install the decorative shell
Note: Take full consideration of the plugging/unplugging space of the
communication cable and the length of the cable during installation to see if
they are appropriate.

Echo Loop：
- PV voltage — PV current — PV power—Battery power — BATT1 voltage — BATT1 current — Max. BATT1 voltage — Min.BATT1 voltage — BATT1 temperature — BATT1 battery type —
- BATT2 voltage — BATT2 current — Max. BATT1 voltage — Min.BATT2 voltage — PV voltage
Temperature units
Operation:
- Step1: Press the button under the battery temperature interface.
- Step2: Press the button to select the temperature unit.
- Step3: Press the button to set successfully.
Clear the generated energy
Press the and button and hold on 5s to clear the generated energy.
Battery type
Operation:
- Step1: Press the button and hold 5s under the battery type interface.
- Step2: Press the button when the battery type interface is flashing.
- Step3: Press the button to confirm the battery type.
Battery type
- The battery voltage is set as default and not changeable when selecting the default battery type. Please change to “User” battery type before adjusting the battery voltage.
- Set the voltage of the “User” battery type via PC software only.
Lead-acid Battery Control Voltage Parameters
The parameters are in the 12V system at 25 ºC. Please double the values in the
24V system.
NOTE
- When the battery type is sealed, gel, flooded, the adjusting range of equalizing duration is 0 to180min, andboost duration is 10 to180min.
- he following rules must be observed when modifying the value of the parameter in user battery type(factorydefault value is the same as sealed type):
- Over Voltage Disconnect Voltage > Charging Limit Voltage ≥ Equalize Charging Voltage ≥ Boost ChargingVoltage ≥ Float Charging Voltage > Boost Reconnect Charging Voltage.
- Over Voltage Disconnect Voltage > Over Voltage Reconnect Voltage
- Low Voltage Reconnect Voltage > Low Voltage Disconnect Voltage ≥ Discharging Limit Voltage.
- Under Voltage Warning Reconnect Voltage > Under Voltage Warning Voltage ≥ Discharging Limit Voltage.
- Boost Reconnect Charging voltage > Low Voltage Disconnect Voltage.
Lithium Battery Control Voltage Parameters
The parameters are in the 12V system at 25 ºC; please double the values in the
24V system.
The following rules must be observed when modifying the parameter values in User for the lithium battery.
- Over Voltage Disconnect Voltage>Over charging protection voltage(Protection Circuit Modules(BMS))+0.2V※;
- Over Voltage Disconnect Voltage>Over Voltage Reconnect Voltage＝Charging Limit Voltage ≥ Equalize ChargingVoltage＝Boost Charging Voltage ≥ Float Charging Voltage>Boost Reconnect Charging Voltage;
- Low Voltage Reconnect Voltage>Low Voltage Disconnect Voltage ≥ Discharging Limit Voltage;
- Under Voltage Warning Reconnect Voltage>Under Voltage Warning Voltage≥ Discharging Limit Voltage;
- Boost Reconnect Charging voltage> Low Voltage Reconnect Voltage;
- Low Voltage Disconnect Voltage ≥ Over-discharging protection voltage (BMS)+0.2V.
- The voltage parameters of the lithium battery can be set, but you must refer to the voltage parameters of lithium battery BMS.
- The required accuracy of BMS shall be at least 0.2V. If the deviation is higher than 0.2V, the manufacturer will assume no liability for any system malfunction caused by this.
Fault indicate
- No alarm for limited voltage fault when using Lithium batteries.
