I have a 5 k Growatt inverter and need to replace my Gel batteries to Lithium Batteries. Please could someone recommend the correct make of Lithium Battery that is compatible for my inverter. 
countless phone calls have not helped to various outlets. 
kind regards

The majority of Li Batteries claim compatibility with Growatt.
Even in the absence of communication compatibility via the Li Protocol, the User mode allows you to set the voltages and other parameters manually.

Thank you for your reply. 
I am a newbie to this and don’t understand the LI Protocol. I have been told Volta, CFE. Some say Sunscink maybe?😭😭😭
