100/50 MPPT Trends Solar Voltage 38v-15v

Hi,

I'm not sure if this is supposed to do this or not. My MPPT 100/50 Solar Voltage is jumping between 38v and 15v continously in same pattern. Even tho if I check solar voltage with multimeter it's staying at same voltage. Picture below, is this normal?

Hi @Atte Varis,

That is not normal, and usually indicates at poor electrical connection at some point between the PV panel and the MPPT.
