USER MANUAL BATTERY MONITOR
First, connect the Shunt in series to the negative circuit of your battery. B- of shunt connects to B- of the battery. P- of shunt connects to P- of output and C- of charge.
Then take a wire of 0.3-0.75 mm². One end of the wire connects to positive of battery, another end connects to B+ of Shunt (either one is ok).
Finally connect the Shunt to the Renogy Battery Monitor by the shielded wire and the screen of the Renogy Battery Monitor display should turn on.
Attention: Please connect as shown. The shunt must be series connected to the negative circuit, DO NOT connect to the positive circuit.
The Renogy Battery Monitor is fixed by tabs, so it is easy to install. First, open a rectangular orifice on your equipment panel according to the size. Then put The Renogy Battery Monitor into the rectangular orifice, and make sure the tabs are locked.
1. Connect and check the current: Power on after completing the connection as shown, the screen should display capacity percentage. If the screen has no response, please check the connection. Then charge or discharge the battery and check whether the display current is equal to the actual current. If the deviation is large, please check the connection.
2. Capacity calibration: On first use, the percentage and capacity are not the actual value, you need to calibrate the capacity to either 100% or 0%.
First set the usable AH capacity of the battery as the preset AH capacity.
For Lithium and Sealed Lead Acid batteries to calibrate to 100% charge the battery fully and hold the "up" key for 3s to set the capacity to 100%
For Lithium batteries to calibrate to 0% discharge the battery completely and hold the "down" button key for 3s to set the capacity to zero.
This will only have to be done on initial installation of the Renogy Battery Monitor or if the Battery Bank is replaced.
3. Check and reset the actual capacity: If you find the displayed capacity doesn't match the actual capacity during use, please check and reset the actual capacity.
For Lithium batteries discharge the battery to 0% and hold the "down" key for 3s to set the capacity to 0, then set the preset capacity as large as possible.
Now charge the battery fully and the displayed AH capacity should be the actual usable capacity. Then set the displayed AH capacity as the preset AH capacity.
For Sealed Lead Acid batteries it is recommended to set the AH lower than the usable rating after conducting a capacity test or consulting the battery manufacturer.
Preset capacity and voltage setting：
1. Press the 
key for 3s to enter setting menu;
2. Click 
or 
key to select the setting items:
3. Select CAP and click the key to enter the preset capacity setting; The set value will flicker, click the key can select other values, click the or key to select the correct values after this click the 
key to quit preset capacity setting.
4. We can set other items with the same method as preset capacity. When all the items are set and all the values are correct, click the key to save the set and quit the setting menu.
Set capacity to zero or full：
On first use or change of the battery bank, the memory capacity should be set zero or full: In the main interface, hold the 
key for 3s to set the capacity zero, the percentage will be 0%; hold the 
key for 3s to set the capacity full, the percentage will be 100%.
Sleep mode wake up operation
1. When the battery current is low, the Renogy Battery Monitor will go into a low power sleep mode, press any key to see the display if needed. When the battery current rises over normal value or the battery starts charging or discharging the Renogy Battery Monitor will wake up.
2. The Renogy Battery Monitor can stay connected to the battery bank since it has a very low self-consumption.
While charging the battery, the LCD screen's backlight will also be slowly flashing. In order to turn off the backlight function,Long press front Keyboard can turn off the backlight, Long press again Keyboard can Wake up the backlight.
