Hi All

I want to " Remote in" to my batteries as I suspect a bad cell. Is there a program I can download to hook up to the batteries via the laptop. My laptop does not have an RS232 port , just USB and an a network ( Ethernet) port.

Any ideas please.

@George Christian ,

You would need a Serial (RS232 - with a RJ11 connector) to USB cable, like this one https://solar-assistant.io/shop/products/pace_rs232

Then download and install PBMSTools. Note that there are plenty of versions out there. Some work with RS232 only, some only RS485, and some even both.

But this version should work fine.
