Nadeem Ahmed Posted April 5 Share Posted April 5 (edited) I have recently installed an Hybrid solar inverter. It is 6KW Inverter (IP65) with dual MPPT controllers. It supports 9KW panels on both MPPTs (combined, meaning 4.5KW on each MPPT). I have the following configurations of PV panels installed: - MPPT1: 325W x 9 + 320W x 4 = 4205Watts (All connected in series) MPPT2: 585W x 8 = 4680W One of my friend mentioned that we should use the exact same configuration with both MPPTs. Can someone please guide me on this? Thanks in advance. Nadeem Onyx PV9000.pdf Edited April 5 by Nadeem Ahmed Quote Link to comment Share on other sites More sharing options...

Just as you don't have to use both. You can have 1 connected and the 2nd one future. That is a clear indication they don't have to be the same.

On the 9+4 the 325w will work at 320w only meaning you will loss 45w which is minimal. Nadeem Ahmed 1 Quote Link to comment Share on other sites More sharing options...
