Growatt grid tie inverter standby??

[the_uglydog]

Hi, we have a Growatt 8kw grid tie inverter. It has been working fine for a few years now, other than a few ISO faults on the panel strings which are repaired. It has recently started going into standby for no apparent reason. No faults show, all strings are within 10 volts of each other and within 20 amps of each other. The grid voltage is within 233 to 225 (230 here) and the hz is never off by more than +- 1hz all within the settings. Any suggestions?

I saw something similar: my daily produced power stats were dropping to 0KW for no reason somwhere around 5pm - where sun was quite high.

I fixed it by setting the time (and/or) country from shinebus if i recall correctly..
