Ditto to Ray and I would add that you have no idea how the batteries were treated or mistreated. I would insist on replacing the batteries or having a very clear and strong disclaimer that you take no responsibility for the condition of the batteries or their longevity.
Unfortunately, I had a similar looking system in front of me on Monday and the 48V battery bank was sitting at three volts. I could not evaluate the Radian or the Mate which the customer reported not working properly prior to the battery getting depleted. How are you supposed to work with something like that? I can replace the battery, but it could open up a whole can of worms with other equipment being inoperable.In fact, that is likely the reason the batteries got depleted in the first place. These are no win situations. Jason On Wed, Feb 24, 2021, 2:02 PM Ray <r...@solarray.com> wrote: > I concur with Dave: Delete and start over.
