I have two SPF 3000TL LVM-ES inverters in parallel and just upgraded to ARK 2.5L-A1 batteries and the system isn't communicating. The manual states I need a RS485/ CAN HUB. Does anyone know where I can get one or replace with like? Thanks! Bill
I run a sustainable lifestyle center in Canada called Ketchum House. One year ago we upgraded to two Growatt SPF 3000TL LVM-ES (Dual phase) inverters and ran AGM batteries without issue.
Last Friday we upgraded to 4 Growatt ARK 2.5L-A1 batteries.
This is what works and doesn't work.
