Hi @Antonio de Sa yes all cables connect and PAL setting confirmed. System has been running for +-6 months and this problem started on Saturday with no hardware/settings change.
I am quite new to this forum. System worked perfectly and since Friday (heavy rains storm) wont change over to ac when batteries are low. Ac available showing 241v on both inverters but drains the batteries and shuts down. Any help on this please? I have restarted both sysytems 5x and still no joy.
