How to connect a comms cable between a giv energy battery and a Growatt inverter.

[Pepe]

Good Evening,

Can anyone shed some light on how to connect the comms cable between a giv energy battery and a Growatt inverter.I can’t seem to find it anywhere in the manuals.

Thanks

Pete

Select suitable cable.

Cut to required length.

Prepare ends.

Crimp connectors (probably RJ45).

Connect cable at both ends.


Edit: Sorry if this seems a bit dry - I thought you were another member

sounds like you haven’t installed a giv energy battery with a Growatt inverter either.

I assumed like you there would be an rj45 socket on the giv energy battery.

Appears to be RS485 twin cable from battery pcb to BMS connection on Growatt inverter. NB I have zero experience of these
There's a 'wiring diagram' on P31

this also has relevant info re Growatt settings: Growatt Inverter + Pylontech Batteries : BMS Comms Guide - https://powerforum.co.za/topic/5164-growatt-inverter-pylontech-batteries-bms-comms-guide/
