PV Power reduces when high AC Load - Multi RS Solar 48/6000

Hi,

I have started having issues with Victron Multi RS Solar 48/6000.

When there is a high load AC appliance being used (induction cooktop, 2.5kw), solar reduces harvesting capacity, only producing approx. 500w, even though PV capacity is 5kw.

When the AC load drops back down to normal levels, approx 600w, the PV then picks back up again to 5kw.

(The sun remains constant during this process, no clouds)

System Info

4 × Pylontech US5000-B

MPPT 1: 6 x 440w panels

MPPT 2: 8x 400w panels

Cerbo GX (Coms to Pylontech & RS Multi)

Thanks for any help :slight_smile:

Hi Sam, what are your software versions?
Are you using DESS?
