EG4 RS232 Firmware Update Cable (LL)
This is the RS232 firmware update cable EG4 uses to flash new firmware onto its LL lithium batteries, part number EG4UPCA232. It is a two meter run (about 6.5 feet) with a standard USB Type-A plug on the laptop end and an RJ45 (8P8C) plug on the battery end. Inside the USB connector sits an FTDI FT232R serial chip, so a computer sees it as an ordinary COM port. It carries three signal lines, transmit, receive, and ground, on 28 gauge wire, is rated to 300 volts withstanding with 5 megohm minimum insulation, and is RoHS compliant.
Order-in: ships from our supplier, usually about a week.

The reason you keep one in the drawer is firmware. When EG4 releases a battery firmware update to fix a bug or change behavior, this is the specific cable that carries it from a laptop into the battery's RS232 port. It is not a monitoring cable and it is not the RS485 comm cable, it is the one cable meant for loading firmware. If you run EG4 LL batteries, having it on the shelf before you actually need it is cheap insurance at under twenty dollars.

EG4 Ethernet Adapter
This is EG4's wired monitoring adapter (part EG4SP18KDLETH), the small box that carries your inverter's data to the EG4 app over a network cable instead of WiFi. It plugs into the inverter's monitoring port, and a standard RJ45 Ethernet line runs from the cable gland on its body back to your router. Three status lights sit on the face so you can read the connection at a glance: INV for the link to the inverter, a cloud light for the reach out to the EG4 portal, and IP for its network address. There is a reset button, and the unit mounts to the inverter with its built-in faceplate. It works across the EG4 inverter line, the 3k Off-Grid being the exception. The reason to run this over the WiFi dongle is that a cable does not drop. If the inverter lives in a garage, a shop, or a back corner where the WiFi is thin, a wireless adapter that keeps falling offline leaves gaps in your history and an app that shows nothing right when you want a look. Wire it straight to the router and the link stays up, so the numbers keep coming in. If there is a network jack anywhere near the inverter, this is the steadier way to keep eyes on the system.

EG4 Indoor Conduit Box Top Plate (100Ah WallMount)
This is EG4's indoor conduit box for the 100Ah WallMount battery and the 6000XP off-grid inverter. It gives the wiring between the two a clean, enclosed run instead of leaving cable out in the open. The box measures 17.8 inches long, 7.08 inches wide, and 7.9 inches tall, and it ships as a kit with the plates, screws, and parts to put it together (model EG4SP48V100AHIDWMBCNDTBOXV1). The part that earns its keep is the matching knockouts on both the left and right plates, so you can bring conduit in from whichever side lines up with your wall and panel. You build it to fit the install rather than working around one fixed opening. Pair it with the WallMount battery and the 6000XP and the finished wall reads like a real electrical job instead of a pile of loose cable.
