I installed a 5000V Axpert Inverter. It recognises the batteries but the solar panels are not being recognised hence the batteries are not being charged by solar.

Got a solution for the Setting Code H5 from this forum.

To include picture

HS is really MS, which I believe simply indicates that that unit is the master. It is not an error code. More than that I cannot help you, but there are more than enough Axpertise around... they will weigh in soon.

Press the down button a few times until you get PV  volts . Must be at least 60 volt to connect . Check voltage at PV input . Plonkster is correct HS is not a error code .

It seems the solar panels are either not connected, or not getting power through to the inverter. Can you measure the voltage on the PV terminals on the inverter, and also make sure the Positive (red) cable goes into the "+" terminal, and the Negative (black) into the "-" terminal.

 

If there's no volt reading, it could be either one of the following problems.

1. If there's fuses, it could have blown a fuse.

2. If there are no fuses, it could have blown a diode on the panels.

3. Or you could have a loose connection somewhere.

Solar panels not showing on the inverter screen, when i press arrow up or down it shows 81-84.4V.The charging by utility power is working nicely. My inverter make is Voltronic 5KV/5000W. I need your help guys.

Are you seeing the frame and no cells, or no frame at all?

The below shows one row of cells inside the frame.

Only patched firmware shows 0, 1, 2, or 3 rows of cells in the PV icon as a crude bar graph of PV power. No cells (empty frame) means patched firmware and less than 500 W of PV power. It could be charging at 490 W for example.

If you are showing ~84 V of PV voltage, you should at least see the PV frame and the dotted line leading from it.

 

Good day all, was this problem solved? I have the same issue - inverter does not display the solar panels. I measured 121Vdc on the terminals though (145Voc system). Thank you.

Having the exact same problem on a Mecer, goes into battery mode with solar connected and good. Unable to sort this out, help urgently needed

Please when you post questions like this you need to provide more information:

1. Model of Inverter (King, MKS, VM etc)
2. Firmware version 
3. Panels (wattage, configuration)

 

 

Also very helpful would be this display screen, if it appears, accessible by pressing the up or down buttons. Your screen may look a bit different, depending on the model. It needs to have the PV, INPUT, and "V" segments lit, near the left (first photo) or near the middle row of digits (second photo).

       

Edit: either a photo of the LC Display on this screen, or just tell us the voltage it shows.

I have two inverters with the same problem. It appears to be caused by firmware. I swapped the control boards with a known working one, and the inverter kicked into action without a glitch. Upon troubleshooting the control card, I could not find any defective component.
