i also started off with watchpower and found it to be mediocre at best, you can use this multisib software, it is pretty good considering it is free.

Grace my ***...... they knew it was faulty and was probably holding out in the hope that you would spend more money with them 

Unfortunately, inverters are not 100% efficient.

@sunset1 - i have a Axpert King (5KW)

watchpower for me was useless, until i found  MultiSIBcontrol.
it happend a few times with watchpower where it wouldnt display any PV readings until i set all the watchpower settings to default, and then it would only display the pv input
try this MultiSIBcontrol

Thank you @87 Dream - thank you for the feedback, changeover switch it is...

I had the same issue at one point - i am using watchpower, and had several settings changes made over time, and i had to set the watchpower settings back to defaults, and then it power was restored from my PV.  (i also had a PV voltage reading, but no power coming from the array)
Not sure if that will be of any use, but defaulting all the settings made my PV work again

Two x 8kw Sunsynk Hybrid Inverters with 4 x Hubble AM2 with 36 x 535w JA Solar panels. 

An update to anyone else who may be struggling with this, apply the settings above as provided by @Coulomb, in that order. In my case the order did matter. Initially I enabled ECO mode and bypass was disabled. After enabling bypass mode, when entering ECO mode the power would cut out, as if bypass was still disabled.
Here are the steps I took go get it working:
1. Disable ECO mode (10 = AUT) and disable bypass mode (23 = BYF) in any order, then exit the settings menu
2. Enter the settings menu and enable bypass mode first (23 = BYE)
3. Now enable ECO mode (10 = ECO)
As a result, my Axpert King inverter is running cool and quiet while there is utility power available and switches to line mode to provide backup power when there is no utility power.

Yes, i tried several times, but there was no comms to the unit at all - usb, bluetooth and serial port, none were working
