Good day. I hope someone can help me. I recently purchased a small house that was built about 2 years ago and have a strange earth leakage trip that happens only between 7:30pm and 8:00pm. It does not happen every night either (probably 3 to 4 times a week)

There is no difference in appliance usage between the evenings that it trips and the evenings that it does not trip. Most evenings are spent on the couch watching TV with nothinge else on but a lamp.

I have a EasuWise geyser unit with solar panel and pump but have even tried turning that off during the hours of 7pm and 8pm and it made no difference.

When the earth leakage trips all plugs stop working but lights and stove remain operational.

I do not have any timers or pool pumps. The

Does anyone perhaps have advice what could be causing this?
