I have no shade problem and I think it might be a connection problem. heat and cold explanation on connectors maybe? it only started this last week sometime when we got minus temperatures. ill open all connection the weekend and put in a compound for better connection and with the main fuse holder(I believe MY ACDC fuse holders installed are not the best). If this still persist ill have to check each panel fuse as last resort.

Hi. Thanks for feedback. So I did all this and checked the wire to inverter. Set it to first mppt. This morning I went to check voltage. It's starts every morning on 120v. I used the tester and it's 120v. As I pull fuses it go up to 291. When I re-engage fuses it starts at 291V and with in 1min it's steady on 238V. It stay at this till sun drops and steadily drops .

Hi I have similar question. The 5kw hybrid luxpower has 2 ports for panels.i have 6 panels in series directly to pv1 and bridged to pv2. On Pv1 and pv2.on the tester I get 288V but inverter state 238V currently . Panels rate at 545 x 6 =3270w and 48.5v X6 = 291 Panel give me an average of 400w each because of placement. 2400w total. Recently I noticed that my V and panel average got lower last few days. I then get a max of 120v / 1230W. If I reset system, or pull the fuses from main system.replace them they immediately go back to 291v /2400w. Why would this happen? Must pv1/2 be bridge or can I have them unbridged? Is this maybe a setting I have wrong? Fuse holders maybe not to standard?
