4. INSTALLATION
4.1. Installation Location Environment
The location of the battery should be in accordance with the operating temperature range and IP rating
specied in the Specication section of this manual. Although the batteries run at a low temperature, proper
airow around the batteries is recommended.
When installing the set, the following conditions should be met:
Please DO NOT install the product in a completely closed area with no air-conditioning. It can overheat
and cause a re.
DO NOT place in direct sunlight or near a source of heat. This can cause deformation, a breakdown, or a
re. Pay extra attention when you place the system near windows.
The battery should not be set where excessive oil smoke, steam, moisture or dust is contained in the air.
Ensure that the batteries are installed in a clean environment with minimal dust.
Avoid installing the set near the ocean. If unavoidable, appropriate air ltration should be used to
prevent salt air in contact with the batteries.
For proper air circulation to dissipate heat, allow a clearance of approximately 30 cm to the sides of the
battery.
DO NOT install the set near heat sources.
If the batteries are being installed in areas of extreme humidity levels, take the following precautions:
A humidity control agent must be placed inside the enclosure, with controlled airow to expel moist air,
and/or the system can be installed in a proper room with humidity control.
The SSLB1 battery is well-designed to be installed in a 19-inch cabinet. A suitable IP54 or above enclosure
must be used if the battery is installed outdoors.

SUNSYNK SSLB1 | Installation Manual11
Please refer to AS/NZS 5139 for the installation requirements in Australia. This product can be installed
under Section 5 of AS/NZS 5139 for Preassembled BS products.

Plug IsolationCap Tail-hood
4.5.2. Steps
1. Put the wire through the isolation cap and Tail-Hood.
2. Swipe the outer isolation layer of the DC cable.

SUNSYNK SSLB1 | Installation Manual13
3. The red is used for the positive and the negative for the black contact. The end of the cable is bunched
at the terminal using a wire clamp.
4. Tighten the isolation cap and plug the contact.
5. Put the positive and negative plugs onto the system and tighten it.
6. Use an isolation cap for unused DC plugs.
4.6. Master-SlaveCongurations
The Master Pack and The Slave Pack, both with the same model (SSLB1), can be used as a single unit and in
multi-units (in parallel) mode. The customers must inform the supplier if they intend to connect more batter-
ies (multi-units mode), so one can double-check master-slave settings because the DIP address conguration
is dierent if the number of batteries in parallel changes. The Master Pack can be used individually, but Slave
Pack cannot be used separately. Each battery can be set as the master or the slave by changing the DIP ad-
dress conguration. Please refer to the attached best practice guidance document.
4.6.1. Single Unit
If you use only a single battery, it is only necessary to connect the positive and negative cables.
4.6.2. Multi-Units
You can add more batteries in parallel to increase the storage capacity. However, no cabinets or racks are
supplied with the battery.
In order to connect multi-units, some steps need to be followed. In this example, it is considered that the
user will connect up to four batteries.

SUNSYNK SSLB1 | Installation Manual14
1. Connect all positive terminals.
2. Connect all negative terminals.
3. Connect all the batteries to the same grounding point.
4. In order to set the master and slaves, it is necessary to set up the DIP switches (ON or OFF).
5. Follow the settings presented below to set the desired conguration.

SUNSYNK SSLB1 | Installation Manual15
6. It is also necessary to connect the CAN/RS485 cables between the units.

6. MONITORING
The battery does not include a monitoring system. However, the user can utilise the inverter’s remote
monitoring app.
7. TROUBLESHOOTING
The Power Lite SSLB1 battery set is designed to run with most systems as a lead-acid replacement energy
storage solution. Lithium batteries have a much higher density related to lead-acid batteries, and they utilise
the settings and protections built into the ancillary equipment, the BMS.
When the battery operation is outside limits, the BMS activates to provide safe operation.
During normal operation, there will be a voltage across the terminals of the batteries. If the BMS activates
its protection circuit, the battery should restart without external assistance once the fault is cleared. The
scenario where this may not occur is on low volt disconnect. In this case, the battery circuit breaker will need
to be turned o and on again to restart the BMS.
In rare cases where the voltage does not recover, it is necessary to apply an external power source to the
battery output terminal, allowing the battery to charge up above the BMS low voltage cut-o. Once the
voltage rises above this point, the BMS will make the battery operate normally.
8. MAINTENANCE
The Power Lite SSLB1 is maintenance-free. However, some verications can be conducted as part of your
overall system maintenance.
Check LED indicators.
Check for any obstruction placed around the battery.
Check battery connections and cables for secure tting or damage.
Check circuit breakers by turning them o and on again.
