Post Subject: Took me a moment to realize what you meant about the 30 dBPosted by rickmcinnis on: 9/13/2022
That spike went away.
Did not seem to have anything to do with lighting. Completely mysterious - it just went away and has not returned.
I have not done anything with the ground rod idea.
I did listen with the ground wire unplugged - a plug with just a ground wire into a socket - and heard nothing at all so I cancelled the ground rod installation.
I am starting to think, after looking at battery usage calculators - that I may have a defective battery. Seems the internet calculators tell me I should be getting far more usage from a full charge than I am getting based upon 400 Ah and 640 watts usage. The 640 watts is constant, per the inverter's meter.
You are far more knowledgeable than I on these matters - do you think 1.5 hours from full charge to 11.6 volts sounds right for 640 watts continuous usage? There are no ups and downs since these are class a amplifiers. Could that alone make a difference?
This afternoon I will have to measure them separately.
