Hi all I have a system running Primo 5 and MultiPlus-II 48/5000/70-48 for some reason when the panels get a good bright burst of sun, say 4.5KW, it triggers an error 105 on the Primo - (frequency shifting) and the Primo 5 reboots. Is this expected behavior or is it an issue? Everything runs fine when the Primo is running at < 4KW
