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.
