 Intelligent BMS features:

• Overcharge detection
• Over-discharge detection
• Overcurrent detection
• Short detection
• Temperature detection
• Auto cell balancing
• Communication

Communication:

The BMS has three RS485 ports one RS232 port.

Two RS485 ports are used for the parallel connection of multiple batteries.

The RS485 and CAN ports are used for inverter-battery communication.

The RS232 port allows for real-time monitoring of the following:

• Total battery bank capacity
• Individual cell capacity
• Battery bank current
• Environment temperature
• Cell temperature
• Charging/discharging current
• Cycle count estimate

The values can be logged on a connected computer or the BMS and can be downloaded on request.

Warranty:

The battery pack comes with a factory-backed 5-year warranty. 70% of rated capacity within 5 years, or 6000 cycles @ 85% DOD whichever comes first.  Please take note of the full warranty terms and conditions. 

Delivery:

Free nationwide delivery on lithium batteries and inverters. Please take note of warranty claims that transport to The Sun Pays office will be the customer's cost.

What's in the box:

• Battery.
• User manual.
• Wall-mount bracket.
• Bolts to mount the battery.
• RS485 Communication Cable x 2

Note:

It is not recommended to parallel an older battery with a new battery. The internal resistances of the batteries and the firmware may differ.
