Zap Set-Up Guide for Inverters

How to connect an inverter to Sourceful Energy with Zap.

1. Locate your inverters network settings

Locate your inverters network settings: IP address, Unit ID and Port Number.
You can usually find them on your inverter's display or you can ask your installer.
Write them down, you'll need them later on.

Is your inverter is supported by Sourceful Energy? See our list of supported inverters.
If Modbus TCP is not enabled, ask your installer or check our configuration guides for inverters.

Important
If Modbus TCP is not supported, you may be able to use a direct wired connection (RS485). Please consult your installer or visit our Discord for advice.

2. Connect Your Zap to a Power Source

You can power Zap in one of two ways:

Option 1: P1 (RJ12) Port
Plug Zap directly into the P1 port on your electricity meter.

Option 2: USB-C Power
If the P1 port isn’t available, power Zap using any USB-C source - a phone charger, computer, or your inverter’s USB-C port.

Important
Zap must stay within range of your Wi-Fi router at all times. Zap must be either:

  • connected by cable to your electricity meter OR

  • connected over Wi-Fi to your inverter (if your inverter is already wired to your meter).

After connecting Zap to a power source, the green power LED and blue status LED should light up on your Zap.
