Settings:
The correct settings on the inverter will aid in ensuring optimal battery life. Here is a guide on inverter settings for the LiFePO4 battery:
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 3000 cycles @ 70% DOD whichever comes first. Please take note of the full warranty terms and conditions.
Please take note of warranty claims that transport to The Sun Pays office will be the customer's cost.
What's in the box:
- 4.8kWh battery
- User manual
- Bolts and nuts to mount the battery in a battery cabinet
- Communication cable for RS232 (RJ11 to USB)
- 2 x 2m LAN cable
- 1 x 30cm LAN cable
- 1m red & 1m black 25mm battery cable
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.
