Connecting to the Battery

Please connect the monitoring screen to the RS485 UP Communication Port of the battery using the included RJ45 Communication Cable to obtain detailed battery information from the battery management system.
If the monitoring screen is used with a parallel battery bank, the communication between paralleled batteries must be enabled. Please connect the RS485 LINK Communication Ports of the former batteries to the RS485 UP Communication Ports of the latter ones using CAT5 (or above) Ethernet straight through cables (not included). The monitoring screen should be connected to the RS485 UP Communication Port of the first battery.
– WARNING

• DO NOT string batteries in series. Doing so can cause catastrophic failure.

CAUTION

• DO NOT string batteries with different chemistries, brands, models, rated capacities, or nominal voltages in parallel.

• Please avoid too high a voltage difference between paralleled batteries, despite the auto-balancing function, to avoid triggering the over-current protection.

• In parallel battery banks, the copper cables between each battery should be of equal length to ensure that all batteries in the system can work equally together.

• It is not recommended to connect too many batteries in parallel if taking advantages of the auto-balancing function.

• Please leave the battery in shelf mode during installation. DO NOT switch the battery to active mode until making sure that all the connections are correct and secure. Connecting active batteries to the system may trigger the short circuit protection of the battery.

Operation

LCD Information

Overview

Present Voltage (V)

The present voltage indicates the real-time terminal voltage of the battery. If the monitoring screen is used with a battery bank, the present voltage will be the average terminal voltage of the batteries in the battery bank.
Present Current (A) The present current indicates the real-time current flowing through the battery or the battery bank. If the charge current is higher than the discharge current, the present current will be a positive value. If the discharge current is higher than the charge current, the present current will be a negative value.
Capacity (Ah)
The capacity indicates the maximum capacity that the battery or the battery bank can deliver under the standard discharge condition when fully charged. The capacity will diminish gradually with the cycling of the battery or the battery bank.
State of Charge (%)
The state of charge indicates the real-time charge level of the battery relative to its capacity. If the monitoring screen is used with a battery bank, the state of charge will be the average charge level of the batteries in the battery bank.
Self-Heating Function Status

The self-heating function status indicates the operation status of the self- heating function. If the self-heating function is not available or not operating, the self-heating function status will be ‘0’. If the self-heating function is available and operating, the self-heating function status will be ‘H’.
Number of Paralleled Batteries
– The number of paralleled batteries indicates the number of batteries connected in parallel in hexadecimal. If the battery is used individually, the number of paralleled batteries will be ‘1’. If the communication of one or more batteries in the battery bank is accidentally disconnected or the monitoring screen fails to obtain the information of all batteries after the battery bank is recovered from the over-discharge protection, the battery icon next to the number of paralleled batteries will flash. Please check the communication connections and long press the Page Up Button and Page Down Button at the same time for 3 seconds to reset the monitoring screen.
Remaining Time (Hour)
The remaining time indicates the time remaining before the battery or the battery bank will require a recharge based on the current discharge rate. If the battery is being charged, the remaining time will not display. If the battery under-voltage warning is triggered during discharge, the remaining time will be ‘0.0H’.
Battery Level The battery level indicates the real-time charge level of the battery relative to its capacity using four battery segments. If the battery is being charged, the battery segments will illuminate one by one repeatedly until the battery is fully charged. If the monitoring screen is used with a battery bank, the battery level will be the average charge level of the batteries in the battery bank.
Error Code The error code indicates the warnings and protections for the abnormal conditions of the battery or the battery bank. If the battery or the battery bank operates normally, the error code will not display. If the battery or the battery bank triggers multiple warnings and/or protections, the monitoring screen will scroll display the corresponding error codes. See the following table for error code interpretation. Please refer to the online version user manual of the battery for the triggering and recovery condition of each warning and protection.

NOTE

• The communication between paralleled batteries MUST be enabled using CAT5 (or above) Ethernet straight through cables before connecting the battery bank to the monitoring screen to obtain the accurate battery bank information.
• If the number of paralleled batteries increases after connecting the battery bank to the monitoring screen, please long press the Page Up Button and the Page Down Button on the monitoring screen at the same time for 3 seconds to reset the monitoring screen and refresh the battery bank information.
• The monitoring screen is ONLY able to obtain the information of battery bank with no more than 900Ah rated capacity.

Button Operation
After connecting the monitoring screen to the battery or the battery bank, please long press the Power Button on the monitor-ing for 1 second to switch the battery or the battery bank to active mode. The backlight will be lit and the LCD Screen will display the present voltage. If no operation is made within 25 seconds, the backlight will go out and the LCD Screen will scroll through the present voltage, present current, capacity, and state of charge. To display a specific parameter, please press the Page Up Button or the Page Down Button repeatedly until the desired parameter shows up. The backlight will be lit once the Page Up Button or the Page Down Button is pressed. If no operation is made within 15 seconds, the backlight will go out again and the LCD Screen will continue scrolling through the present voltage, present current, capacity, and state of charge. Prior to long periods of storage, please disconnect the battery from the system and long press the Power Button for 3 seconds to switch the battery or the battery bank to shelf mode. In shelf mode, the battery has a low self-discharge rate and can hold the charge for a longer period of time.
