Pytes E-BOX-48100R 5.12kWh 100Ah 48V Lithium Solar Battery Pack

Can you please provide a chart that displays voltage readings as a reflection of the state of charge?

The corresponding relationship between voltage and SOC is different at different temperatures, different charge and discharge rates, and different lifespans. So LFP battery controls the battery operation through the SOC, not voltage. 

What Is the operating temp range for both charge and discharge? 

Charge temp range is 32F - 113F

Discharge temp range is 14F - 122F

What is the best way to store the batteries if they are not being used? 

When you get the battery, the SOC of each battery is 45%~50%. Usually it could be stored for 3~6 months. The battery needs to be recharged every 6 months to more than 80% SOC. If you want storage longer(>6 months), please charge it to 80% SOC first. But usually long-term storage is not recommended because it will influence the performance of the battery. See the installation manual for more specifics on storage temperature. 

Does the E-box have built-in over current protection?

The battery has BMS protection, the battery overcurrent protection will be activated after the current exceeds 102A for 15s, and then If the current is as high as 200A (0.1s).  The secondary protection of the battery will be triggered at this time, and the BMS will control to turn off the mosfet to cut off the circuit. If the current exceeds 320A after a period, the fuse will be blown to protect the circuit. In this case, a new BMS board needs to be replaced to make the battery work again, because the fuse is integrated on the PCB board. (But usually it takes time for the fuse to blow, and the BMS protection will be triggered to turn off the mosfet to disconnect the circuit before fuse is blown, The breakdown current of the mosfet is 800A, so usually the hardware will not be damaged by overcurrent.)

Any compatibility issues with XW6848 pro or Outback Radian inverters? 

XW6848 Pro and Outback Radian inverters are compatible with Pytes batteries with open loop communication. Additionally, systems with these inverters would not have UL9540. Check with altE for the latest compatible 9540 inverters with this battery, as more are being added often. 

There are additional technical notes regarding compatibility with Outback and Scheider inverters in the documents tab above. 

Can we get a copy of the terms of the warranty? 

Yes, it is posted in the documents tab above. 

What additional components are required to maintain UL9540 when using E-Box with Sol-Ark?

See the Sol-Ark Guide in the documents section above.
