RS450-200 MPPT every ten minutes does sweep/shuts off for 33 seconds

Q&A and troubleshooting

Its been discussed before but no real answers.

I have 3x RS MPPT 450/200, and all 3 at the same time, in full sun, no clouds, etc., shut down every 10 minutes for nearly a minute! and then come back online.

thats a lot of power lost?

Meanwhile my Fronius PV inverter is rock solid nearly 100% uptime.

any ideas?

Give us a little information about the PV panels.
Number of panels per tracker, panel’s Voc, panel’s Isc, etc.
