Hi Rias, you can, yes.

questions ELIZE on 30/12/2020

Good day. How many ah is tis battery?


Hi, it's 100Ah@ 50Vdc

questions Rob Entzinger on 20/12/2020

What are the differences between a Hubble and BSL Bull besides the 200Wh capacity.? Which is the better buy ? Do either have communication capabilities ? if so what type RS232/TCPIP/wifi ? Thanks in advance Regards RobE


Hi Rob, the Hubble doesn't have a CAN-bus. If you 're wanting a battery to communicate well with Sunsynk, Deye or Victron inverters, this one is the way to go. 

questions Neil on 21/11/2020

Does this battery integrate via BMS with sunsynk allowibf SOC to be read by inverter and does it come with communication cable for inverter? How does it compare with Hubble and shoto?


Hi Neil. Yes, it does and it comes with a comms cable. The Shoto and the GHUblle don't have comes with the Sunsynk at the time of writing.

questions Jaco on 18/11/2020

Can I connect it to the CenturionSolar controller and Axpert 5kw inverter and will it come with such instruction?


Hi Jaco, if I understand your question correctly, yes you can use it with an Axpert but there is no integration with the ICC controller.

questions Jaco on 18/11/2020

Can I use this with my existing two Pylontech batteries?


Hi Jaco, no you can't do this. You'll need to stick with Pylontech's.
