Can internal Trace Xantrex timings be changed?
We have the stacked Trace/Xantrex SW4048 inverter. Still working great. We have it connected to batteries and a generator (through its AC2 input). When grid power goes down, and LCBO goes low enough, the generator turns on as expected. With good voltage on AC2 for about 30 seconds, the inverter switches over to generator just fine.
But then when grid power comes back on (AC1 good), the inverter waits 4 minutes or longer before it will switch back to AC1. During that time, it is running our small battery pack down and down. It says AC2 is good in just 30 seconds, but takes over 4 minutes to say AC1 is good. I know this is not because the grid power is unstable or bad - it will behave this way when the grid is on perfectly and I'm just switching the grid power off to test the inverter.
It has always behaved this way, so I suspect this is normal behavior - to wait longer on a good AC1 than AC2.
I would really like to shorten the time the inverter waits to accept power from AC1. I find nothing in the setup menus to control this wait time. Is there something anyone has found that allows me to change this? Two minutes would be way better!
Is there some way to enter a hidden setup menu that is not in the manual? Or have I missed a setup parameter in the manual?
Can anyone help me with this?
Thanks very much for having this forum where we can post about these inverters.
