Antminer s9 miner fluctuates a lot. Is this normal? Pics

From my understandings the power provider has 230V. Could this affect?

You should add backup pools to your config, or at least clear out the default pools unless you want to be mining for bitmain when your primary pool goes down.

If you look at the second screenshot you posted, the very last column LSTime, you can see the problem.

Your miner connected to and supplied work to your backup pool less than 10 minutes before your screenshot was taken.

The dip on your main pool is a connection issue causing it to mine on the backup pool for short periods of time.

I would either remove those backup pools or better yet, set yourself up a failover pool that isnt mining to bitmain.

Thank you for your answers. So why does it disconnect? Is it a problem with the pool? With my internet connection? should I actually find a second pool there ?

We dont know enough about your setup to answer those questions. Yes you should absolutely find a second pool, if the primary fails the miner will sit there burning power and profits.
