Hello,
About two months ago I had a system installed as itemized below and have read most of the manuals so far. I am not an installer and have no prior knowledge or skills in solar systems so please keep that in my mind when responding.
I am thankful for this forum and, like many users, will be consumer at first before I can contribute to others. If I don't thank you when you respond, please know that I do appreciate your responses.
Question 1
Often, when my battery bank is completely charged, I will turn on my inverter to run the air con for a couple hours or other power-hungry devices like the microwave or induction stovetop. Almost immediately after turning on the inverter, my Skylla-i Control GX unit will flash the red, "Low Battery" light then turn off the air con. Then, 10 seconds to a minute later, the light will go off and the air con will start back up. This process will repeat non-stop. Why does the "Low Battery" light come on when my 1,000AH battery bank is fully charged?
Question 2:
I read somewhere that it's not ideal for lithium batteries to always be topped off and in float mode between uses, as mine are. Is that true? Will the answer depend on whether you are full-timing or storing your RV?
Question 3
I read that one of the benefits of lithium batteries is that you can safely discharge them to at least 20%. However, my installer set the "Discharge floor" value to 48%. Does that seem reasonable or can I safely change that to 20% to reduce my costly and noisy generator use?
