• AES RACKMOUNT: 48-48-5120, 48-48-5120-H

OutBack Power Inverter-Charger

• GS8048A

NOTE
LYNK II Communication Gateway

• The LYNK II communication gateway is not required in an open-loop configuration. However, it is a useful tool to diagnose the battery. For example, by connecting the LYNK II to the battery, you can access the battery logs, which can be used to confirm if the inverter charge settings are fully charging the battery.
• As another example, use the relays on the LYNK for automatically starting a generator, load shedding, load enabling, and turning equipment or warning lights ON/OFF.

Minimum Battery System Capacity

Battery charge and discharge rates are managed automatically by the Discover Lithium Battery and Out Back Power device. Using large solar arrays with battery banks that are too small can exceed the operating limits of the battery to charge and possibly lead to the BMS triggering over-current protection. Battery capacity must accept the maximum charge current of the system, or charging must be curtailed below the operating limit of the installed batteries. Derive this value by adding together the charge capacities of all inverter-chargers and solar charge controllers in the system. Additionally, battery peak capacity must support the surge requirements demanded by the load attached to the inverter-charger. Match all inverter-charger peak power values with the sum of all battery peak battery current values.
Inverter Peak = (Inverter Surge Value) / (Inverter Efficiency) / (48V: Low Battery Cut-Off)

FN-DC Calibration
The following describes how to calibrate a FLEXnet DC (FN-DC) battery monitor that is already installed in a system. The system should already set up with a MATE3-class system display, HUB communications manager, inverter, and/or charge controller. This procedure requires a digital multi-meter (DMM) and a slot screwdriver.

CAUTION
ELECTRIC SHOCK HAZARD

• Follow all safety precautions when working with energized equipment.
• Use Personal Protective Equipment, including clothing, glasses, insulated gloves, and boots.

Failure to follow these instructions may result in injury.

1. Ensure the battery bank is fully charged.
2. De-energize system.
3. Remove the FN-DC.
   • Maintain all wired connections (including the green communication cable to the HUB).
4. Place the FN-DC so the informational sticker is facing up and the terminal block is facing away.
5. Press the two push-tabs and remove the FN-DC front cover.
6. Remove the red sealant from the trim pot for the battery (R83).
7. Energize the system.
8. Use the DMM to measure the battery voltage at terminals 1 and 2 on FN-DC inputs.
9. Read the battery voltage from the MATE3 battery screen (visible by pressing the BATTERY soft key). Figure 3. MATE3 – BATTERY soft key
10. Use the slot screwdriver to adjust the trim pot (R83) until the displayed voltage of the FN-DC in the MATE3 display matches the measured battery voltage (measure using the DMM between terminals 1 and 2).
11. Replace the front cover.
12. Replace the FN-DC back into the system.

Optimizing LBCO Function with MATE3 Controller
NOTE
For a more accurate Low-Battery Cut Out (LBCO), use the battery SOC relay on the LYNK II communication gateway. Refer to A1. LYNK II: Overview.
Using a MATE3s controller allows for control over the LBCO delay and should be set up using the parameters noted. However, if a MATE3 controller is used, the inverter’s Low Battery Cut-Out timer (5 minute minimum) is not optimized for use with heavy inverter surge loads and a lithium battery. Use the set up outlined below to manage the system when using a MATE3 controller.

FLEXnet Settings (B)| MATE3 Menu| AES LiFePO 4 42-48-6650| AES RACKMOUNT 48-48-5120 / 48-48-5120- H
---|---|---|---
Relay Mode – Invert Logic| B-3| No
Relay Set Points – Voltage| B-4| High = 53.0 V Low = 49.6 V
Relay Set Points – SOC| B-4| High = 0%
Low = 0%
Relay Set Points – Delay| B-4| High = 1
Low = 0

This timer may prevent the inverter low battery cut-out from occurring before the battery BMS self-protects and shuts the battery down. To avoid this situation, use the relay contacts on the FLEXnet DC Battery Monitor to trigger the low voltage cut-out. Connect the relay contacts to the INVERTER ON/OFF terminals. Once the relay is triggered, the inverter is set to OFF and prevents the battery from being discharged below the battery BMS protection voltage. Refer to section 4.5 FLEXnet Battery Monitor Settings for the recommended settings.
Connect the FLEXnet DC Battery Monitor relay contacts to the inverter as follows.

Settings for MATE3 and MATE3s SOC Warnings

**MATE3(s) Settings (M)| MATE3(s) Menu| AES LiFePO 4  42-48-6650| AES RACKMOUNT 48-48-5120 / 48-48-5120- H**
---|---|---|---
FLEXnet DC Advanced – Low SOC Warning Level| M-8| 15%
FLEXnet DC Advanced – Critical SOC Warning Level| M-8| 10%

APPENDIX

A1. LYNK II: Overview
Although mainly used in closed-loop systems, the LYNK II has other features that may be of use in an open-loop charging system.
LED on the LYNK II visually displays the battery SOC in 20% increments.

• The LYNK II enables access to the battery logs, which record various events involving the battery. The battery log includes battery cell voltage, cell temperature, and charge current, which is useful for troubleshooting and calibrating the charge settings.
• Relays on the LYNK II turn ON/OFF based on various conditions on the battery. You can use them for automatically starting a generator, load shedding, load enabling, and turning equipment or warning lights ON/OFF. Configure the LYNK II with the LYNK ACCESS software, which runs on Windows operating systems only.
• LYNK II and LYNK ACCESS provide information about each battery in the battery bank.

A2. Installing and Connecting LYNK II to Batteries
NOTE

• Turn OFF all devices before connecting cables.
• Do not plug an AEbus RJ45 network cable or terminator into the 10/100 Ethernet port of the LYNK II.
• Do not connect a CAT5 or higher cable from the AEbus, LYNK, or Ethernet ports of the LYNK II to a WAN or MODEM port of a network router.
• Mixing the LYNK Network with other networks may result in equipment malfunction and damage.
• Locate the LYNK II close to the batteries and avoid paths where there may be power lines or equipment that generate a lot of noise and interference.
• Unless Discover Energy Systems specifies, power electronics must not be connected directly to the LYNK or AEbus network.

Refer to the LYNK II Installation and Operation Manual (805-0033) for detailed instructions on network layouts, connections, and terminations for compatible Discover Lithium battery models. Some key reminders are provided in this manual.
