• Hours: Refers to the duration (in hours) of each equalization charge cycle. This value is adjustable, allowing users to specify how long the equalization charge should run.
• AC Charge Amps: Indicates that the battery is currently set to charge from an AC source.

Users can manually set or adjust both the interval (in days) and duration (in hours) of the equalization charge, according to system requirements or maintenance schedules.

Notice

Do not alter these settings too often on the same battery, as it may damage the battery.

Generator Connection

A generator may be connected to the grid input.

The inverter treats generator input as grid power. Important: In this case, ensure that all power is used for Load only and is not exported, as this could damage the generator.

Warning

The generator must be capable of supplying both the load current and battery charging current simultaneously.

Battery | Shut Down

The Battery Shut Down page allows you to set the thresholds for when the inverter should shut down, alert the user about low battery, or restart. These settings ensure proper battery management and prevent excessive discharge that could harm the battery.

Access this page by tapping the “Shut Down” option under Battery Setup.

What you can do from this page:

• Shut Down: This setting indicates that the inverter will shut down if the battery voltage falls below 38.0V.
• Low Battery: This setting triggers an alarm when the battery voltage drops below 38.1V.
• Restart: The inverter will restart the AC output when the battery voltage reaches 39.0V, ensuring proper functioning once the battery has been sufficiently recharged.

Notice

Activating Shutdown causes the inverter to enter standby mode. It does not fully turn off the inverter. The total shutdown occurs only when battery voltage drops below 19V.

The voltage shown on the Sunsynk Inverter varies depending on whether the inverter is charging or discharging the batteries.

Battery Level	Discharge Voltage	Charge Voltage
Fully Charged	50.54V (x4 = 202.16V)	58.80V
75% Charged	49.60V	54.80V (Discharge Mode)
50% Charged	48.60V	50.80V (Discharge Mode)
25% Charged	48.00V	48.00V (Discharge Mode)
0% (Shutdown Trigger)	47.50V	-

*The table shows approximate values for a 48V system. For lithium batteries, values will differ slightly.

*For best performance and battery life, avoid setting the cut-off voltage too low.

The Sunsynk inverter is compatible with AGM Lead Acid and Lithium Battery Banks. Below is a brief explanation of each:

1. AGM (Absorbent Glass Mat):

• A sealed lead-acid battery design with internal mats that absorb and immobilise electrolyte.
• Ideal for deep-cycle applications.

2. Lithium (LiFePO 4 ):

• Longer lifespan and high efficiency.
• Must use manufacturer-defined charging profiles.

STATE OF CHARGE

1. Bulk Stage:

• Delivers a large current to restore most of the battery’s capacity (~80%).
• Continues until voltage reaches the set absorption level.
• The proper charger supplies current based on the battery's Ah rating.

2. Absorption Stage:

• Voltage is held at a higher level to complete the final 20% of the charge.
• Required to fully saturate the battery and avoid sulfation.
• Typical AGM absorption voltage: 14.1V – 14.8V DC (depending on model).

3. Float Stage:

• Voltage is reduced to 13.0V – 13.8V DC to maintain the charge without overcharging.
• Ensures battery is ready for use while preserving lifespan.

4. Equalization (Lead-Acid only):

• Periodically increases voltage above normal levels to desulphate the battery plates.
• Not used with lithium batteries.
• AGM batteries benefit from this occasionally if recommended by the manufacturer.

Battery Management System (BMS)

After installing a lithium battery, verify that communication between the battery and the inverter is working properly. To do this:

1. Tap the BMS icon on the screen.
2. Check whether the battery information appears correctly.

If no data or incorrect data is displayed (as shown in the examples below), a communication error has occurred.

If a BMS communication issue is detected:

1. Check that the data cable is the correct type (e.g., RS485, CAN, or manufacturer-specific).
2. Ensure the cable is connected properly into the appropriate BMS communication port.

Some battery manufacturers use communication protocols other than RS485 (such as CAN). Refer to the battery manual for exact connection requirements.

It is crucial to refer to the manuals that manufacturers produce for their batteries. That way, the chance of errors occurring during installation is significantly reduced. The following batteries are compatible with Sunsynk Three-Phase LP IP65 Inverter:

• SUN-BATT-5.32
• SUNSYNK-L5.3
• L051069-A

Grid Setup

• HV2 (Over Voltage Protection Level 2): Set the level 2 overvoltage protection point.
• LV1 (Under Voltage Protection Level 1): Set the level 1 undervoltage protection point. The inverter disconnects if the grid voltage falls below this level.
• LV2 (Under Voltage Protection Level 2): Set the level 2 undervoltage protection point.
• LV3 (Under Voltage Protection Level 3): Set the level 3 undervoltage protection point.
• CA_LHVRT: Configuration of over frequency and under frequency of the grid power. Once enabled, LF1, LF2, HF1, and HF2 are all effective, and when disabled all are ineffective.
• HF1 (Over Frequency Protection Level 1): Set the level 1 over frequency protection point. This setting will disconnect the inverter if the grid frequency exceeds the threshold.
• HF2 (Over Frequency Protection Level 2): Set the level 2 over frequency protection point.
• LF1 (Under Frequency Protection Level 1): Set the level 1 under frequency protection point.
• LF2 (Under Frequency Protection Level 2): Set the level 2 under frequency protection point.

System Mode

Example:

• During 02:20-11:19, when the battery SOC is higher than 65%, the inverter will discharge the battery until the SOC reaches 65%. The power output will be capped at 6000W.
• During 11:19-11:20, when the battery SOC is lower than 65%, the inverter will use the grid to charge the battery until the battery SOC reaches 65%. It will draw up to 6000W of power.
• During 11:20-16:20, when the battery SOC is lower than 100%, the inverter will not discharge the battery.
• During 16:20-22:20, when the battery SOC is higher than 65%, the inverter will discharge the battery until the SOC reaches 65%.

Advance | Multi-Inverter

This screen allows you to configure multiple Sunsynk inverters to work together in parallel. Use this page when installing a system with more than one inverter connected on the same AC bus.

What you can do from this page:

• Enable Parallel Mode: Switch ON the parallel function so the inverter can work with others in the system.
• Primary or Secondary Role: Select whether this inverter acts as master or slave on the communication bus.
• Set Modbus SN: Assign a unique Modbus Serial Number to this inverter for communication. Each inverter in the parallel system must have a different number.

The Three-Phase LP IP65 can operate as a standalone unit or in a parallel configuration to increase power capacity.

PARALLEL SYSTEM LIMITS

• Up to 3 inverters (1 Master + 2 Slaves).

INSTALLATION GUIDELINES

• Battery bank: All batteries must be connected in parallel.
• Cabling: Use a minimum 50mm² cable with fuse isolators per inverter.
• Protection: Each inverter requires:
• Surge-protected fuse isolator.
• RCD for each inverter.
• Changeover switch (if powering main loads during outages).
• CT coils: Only connect to the Master inverter.
• Communication: Use RJ45 cables to connect the inverters.
• Cables are bidirectional (no IN/OUT).
• Max length between units: 2 metres.
• Each inverter must have a unique Modbus SN.

Notice

• Ensure all inverters have the same firmware version before configuring.
• Isolate each inverter’s load output with individual load breakers before connecting them to the common parallel breaker.
• Only enable breakers after all units are programmed and tested.
• For three-phase systems, verify phase rotation is clockwise before powering on.

Warning

To ensure the proper functioning of the parallel operation, it is important first to establish the work mode for both the Master and Slave inverters and then make the necessary wiring connections.

If you make the connection prior to changing the work mode, an F15 error will be displayed on the Fault Codes page. In the event of this error, please maintain the connection and proceed to the settings to modify the work mode as presented above, and wait approximately 3-4 minutes. After that, the device should return to its normal working condition, with the error cleared.
