Thee phase Multiplus 2 5000-48 & Solis 3p15k inline configuration

Q&A and troubleshooting

Hi

I’m planning a three phase backup battery system with Multiplus 2 5000-48 inverters.

I have 13.05 kWp PV array and Solis 3P15K inverter. The PV’s rarely output higher power peaks, and so far the maximum has been 16.34 kW and few ~15.5 kW peaks. I’m assuming this happens when a cloud works as a lense. The 3P15K is specified to 16.5 kW peak output power.

Can the VE 5 kVA models handle these spikes? The “Factor 1.0 rule” only talks about the PV array Wp value, not actual spikes.

2024-05-07, 16.34 kW

Does anyone have experience with Solis 3pXXk inverters, do they work in inline cofiguration? Or am I stuck to parallel config?

Thank you!
Kind regards, Esa

You will be on/slightly over the limit, 5k multiplus 1.0 rule is 5kwp solar

I would recommend bigger multiplusses or pv on ac in side

Also keep in mind that you have enough battery power for our ac pv, in your case 75kw (lithium) is recommended
