I have a strange problem with my Victron setup. First the setup: Two houses which I plan to take off grid on the countryside in Sweden. Both equipped with a Multiplus and a SmartSolar MPPT (250/100), then connected to a battery bank of regular led-acid 12V batteries. The solar array is equipped with 4 300W Solitek panels each with Tigos smart optimisers (TS4-L).
Now to my problem: During good sunlight the output is very “spikey”, meaning current and voltage goes from full to zero and sometimes the current spikes in VRM even shows up to 15kA (is this even possible??). Anyone with similar experiences with similar setups or any tips on how to get a more stable output?
See screenshots from VRM & VictronConnect (both at full sunlight on the panels).
