  1. Question: Dyness batteries maximum charge??

    Golf_Nutt posted a topic in Batteries
    Hello, I had a system installed few days ago. Deye 5KW inverter and 2x Dyness 5kw batteries. Panels coming when they eventually get stock. I have a few questions to those who know more than me about these things: 1. The installer said the system is set to only discharge the batteries to 30%. Is this normal? 2. The batteries never reach a full charge? They get to 80% of max capacity and then stop charging? Surely this is not normal. See attached pics. Is this a setting on inverter causing this or faulty batteries? Or is this normal? So, if the system is set to only discharge the batteries to 30% and only charge to maximum 80%, that means I only get 50% usage form a battery? What's the point of Lithium then, as this is the same % I can get from cheaper lead-acid, no? Feedback or input much appreciated.
