That doesn’t look compliant. Issues like exposed GP cables and missing junction boxes are clear violations of basic safety standards. According to the Solar Panel Maintenance Checklist, such problems must be addressed promptly. Get a certified installer to inspect the system and confirm if it meets national regulations.

For your Kodak OG 5.48 and Pylontech UP5000: Use 8 x 555W panels in series if all face the same direction. If panels face different directions, use 2 strings of 4 in series (then parallel). This keeps you under the 500V limit and ensures proper MPPT operation.

Yes ga_za, start with sections 3 and 4 to avoid delay. the minimal shade and no repairs needed. Avoid top floor roofs for now due to membrane issues unless you're fine with later removal.

It sounds like an RS232 connection might be necessary for proper communication. Try using a USB-to-RS232 adapter. Also, make sure the firmware file exactly matches your inverter model and SN.
