I have a Dual 15K setup that has been working for over a year now. I'm grid tie with batteries, so I use a mix of batteries and grid.
The biggest annoyance I have is the discrepancy between my Battery set points and the actual measured battery voltages, when there is excess solar.
Without enough solar to power loads, the batteries charge to my Absorb and Float set points.
When PV input power is in excess of loads, the voltage will exceed my set points by 0.4-0.5V
So, with set points of 55.2V Absorb and 54.0V Float, I hit 55.7V and 54.4V respectively with excess PV.
I thought it may be fixed with a FW update, but it had no affect. Seems like it is something that could be fixed in the FW.
I realize it may not be a "big deal", but It's nice for the inverter to do what I want, all of the time, no just some of the time.
Anyone else have the same problem, are they all this way?
