Hi All, I'm wondering if anyone can explain this strange phenomenon that I am experiencing with my Synapse/Axpert King 5KW inverter. I have a number of light and plug circuits in my house permanently connected to the inverter and every evening the lights on one of these circuits are constantly flickering. This happens only in the evenings (never during the day) and it only happens on 1 of 3 light circuits. If I press the bypass button on the inverter, the flickering immediately stops. If I change back from bypass to inverter mode the flickering starts again. Next morning everything works fine again. 

Any ideas on what could possible cause this?

It can by caused by an appliances that uses pwm in its control. It does it with my coffee machine and 3D printer. Only also on some lights. Have a look at what is running when your lights flicker and switch off until you find what is causing it. It is because the inverter is too slow to control the output voltage. 

Check your Neutrals. The Neutral must not be shared between Essential & Non Essential

I noted my LED lights also flicker random now and then, when Eskom is off line. This is highly annoying.

I have a 5kVA Victron Multiplus II with a Freedom Won 5kVA battery. Neutral is separated and not shared between AC1 and AC2. This happens regardless of battery charge state, and regardless of whatever other loads are running.

Does anyone have a solution to this problem please?

The likely reason for this is that the neutral, when Eksdom is AWOL, is floating and not tied to ground, most likely, check if there's a voltage between earth and neutral behind the inverter (AC Voltmeter), I guess, with and without Eksodm,  be careful, 100+V could be there...

If there is a voltage once commercial power is gone, then you need to implement a automatic switch that will bond earth and neutral on the output side of the inverter, once commercial power is absent...
