SOLVED: Updated the firmware to the latest version and now everything is operating as it should.

Let's take the total input voltage out of the question since I am testing using just one array, so just 380v input. Maybe we can break this down one question at a time. Since this is a non-isolated system, should the panel frames be grounded to earth at the array or not?

I have parameter 37- PV Parallel disabled. I do not want my strings to be paralleled in case I have shading on one string and not the other. I talked to tech support at watts247 and they agreed that disabled is the proper setting. The inverter shows my two individual strings each at about 380v.

I have bought two Jakiper 48v rackmount batteries and have a full size server rack that I am going to mount those in next to my electrical panel. I am also planning on purchasing the MPP LVX6048WP when it becomes available. My question is, has anyone rackmounted an inverter intended to be wall...

The rack is fitted with fans in the top and the front and back are open mesh. Hopefully that would be enough to expel the heat.

Thanks for the reply. This inverter has two MPPT inputs, each of which can handle 600v, so I don't believe I have an issue there, or am I wrong?

I have tried with just one array at a time and still have the same issue. The manual does show an example of having nearly 750v connected with 494.4v on MPPT1 and 247.2v on MPPT2.

I just finished installing my system as shown in the attached pic. Here's a quick rundown of my system. Two arrays of 11 Jinko 265W Class A poly panels. Each array puts out around 380V. They are both on the same ground mount about 200ft from the inverter/main panel. LVX6048WP Inverter. Two...
