FLEXMax60 Charge Controller makes click noise when waking up

Post by arktikgal »

Hi there.

Hoping someone can help us. We recently installed a FLEXMax 60 Controller. It is working well however it makes a series if annoying clicks when it is first waking up.... usually lasts about 30 min or so. Once it is fully awake it is silent.

Any suggestions on how to stop the clicks?.... or did we just get a controller that doesn't like mornings?

txs!

Welcome to the OutBack forum.

Have you tried increasing the Wake Up mode time in the Advanced menu?

txs Kurt... will try that. It is unfortunate if we have to change the setting all the time as we live in the Arctic and get huge swings in time/light. In the winter our shortest day is about 4 to 5 hours of daylight vs summer 23 hours... and it never gets dark! c

page 47 i think of the manual . You can set to a longer time between wake up testing its self ... i think out to 15 minuets .
You will then only have the click every 15 minuets until it compleatly wakes up .
