I have an older XW6048 inverter, and recently changed out my 11 year old Concorde 256ah AGM's to 2 Trophy 230ah lithiums. It all works fine, except for one little quirk - the inverter grid sell display and transformer will not turn off with the end of solar charging each day. I don't like the transformer, etc. to be 'powered up' all of those non sun hours, and would like it to shut down like it did every previous day with the AGM's. I found I can manually kill the grid support function by simply disabling it on the SCP, and then immediately enabling it. It remains off, and does not activate until the sun comes up the next morning.
@Solar Guppy suggested that since the lithiums don't drop their voltage like AGM's do when solar charging is removed, the small voltage drop, will not trigger the grid support 'function' to turn off, thus leaving the transformer & display on overnight. As he also suggested, raising the GSV setting to a higher setting may allow this to work as it did with the AGM's. I did try the XW advanced grid support setting of 64 volts once, and it did disable the transformer & inverter display overnight, but it also triggered a high voltage alarm on one of the Trophy batteries.
Since my grid seldom goes down, and I would rather not have my batteries continuously sitting at a high SOC, I have my GSV currently set to maintain 80-90%. Does anyone have an idea about any other way to have my inverter shut down for the night, without having to use a very high GSV set point? I do it manually every night now, but sure would like it to do it automatically.
Thanks!
