Solar Edge inverter error code 18xB7 HW error? what does it mean and how do we fix it?

Yes, it is possible to connect an FBI2000W inverter to solar panels. In fact, inverters are an important component of solar power systems, as they convert the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity that can be used to power homes and businesses.
To connect the FBI2000W inverter to solar panels, you will need to:

1. Install the solar panels on your roof or other suitable location and connect them in a series or parallel configuration to achieve the desired voltage and current output.
2. Install a charge controller between the solar panels and the inverter to regulate the flow of electricity and prevent overcharging of the battery bank.
3. Connect the output of the charge controller to the input of the FBI2000W inverter using appropriate wiring and connectors.
4. Connect the output of the inverter to your home or business electrical system, following all relevant electrical codes and safety guidelines.

It is important to note that connecting solar panels to an inverter can be a complex process that requires specialized knowledge and expertise. It is recommended that you consult with a professional installer or electrician who can help ensure that your system is properly designed, installed, and configured for optimal performance and safety.

You need to call the installer on this.

Solar panels produce DC voltage.
some solar panels have the inverter integrated into each solar panel.
I would suggest contacting a local solar panel supplier and asking them if they could add a Battery Charging System to the Solar panels you use. An then what sort of inverter to add to the bank of batteries.
An inverter converts DC voltage to AC voltage to use in the grid.
The AC voltages and DC voltages involved have the possiblity to kill if you much around with electricity.

Error means the leading edge of the sheet of paper did not arrive at the preregistration sensor in time, causing a jam.
To fix - Open the inverter door and clear area 14. Open the printer right front door and clear area 2. Retry printing.

I was not able to find a schematic for your inverter, only the user manual and some bad news.

I found the manual, and the error codes start on page 41.
W002 something like input under voltage and E007 IGBT sat, what ever that means.
Save the manual for future usage.

Sadly, I think you will find that a Sharp warranty does not cover this type of fault. It is attributed to either a lightning strike or a power surge. Perhaps your utility company could advise you particularly if you have date and time of failure. The inverter will likely have to be replaced and you should confirm that the replacement is legal in your area as some units have beeni banned in wide geographic areas. You might have to try another brand. Other than your utility company, Sharp, or maybe Infinigi, I am not sure who might give you advice. Possibly you might contact the Department of Energy (if in the US) about a grid tied inverter or NREL. Here is information from EVACO: https://ecavo.com/best-solar-grid-tie-inverters/

code URC HW error: HW usually stands for hardware which means some part of the electronics has failed. Without a model number I can't look up the code "URC" but I'd suggest you do a search on the web for "Motorola model ##### error codes"

How are the batteries for that inverter? Have you got a dead battery in the loop?

Look in Printer Manual (usually in the back) for error codes.

Try cycling power including unplugging AC cord from printer for 1/2 hour.
