    Physical Requirements

    Please securely mount your solar panel & connect the leads to the micro-inverter. Then attach the AC cable to the Inverter and plug it into an outdoor outlet. If your Inverter shows a blue light, then you are good to install the Inverter in our App or desktop. If the LED on the micro-inverter is red, it is better to wait for some more sun or to better position your solar panel!

    Software Requirements

    Download the CraftStrom mobile app from Apple App Store or from Google Play and sign up by creating your CraftStrom user account & password. You can now install the Micro Inverter in our App by scanning the barcode on it or on the box it came in.

    Factory Reset

    If durning the installation process you can not find the HF-A11 network of the inverter, please make sure you are using a 2.4Ghz network and enable WPA security settings. If you still can not locate the HF-A11 wifi signal, then you may need to factory reset your device, you can locate the “RESET” button on your CraftStrom micro-inverter. Follow these steps: First delete Inverter ID in App under Settings  – Devices! PRESS AND HOLD FOR 5 SECONDS – RELEASE FOR 2 SECONDS – PRESS AND HOLD AGAIN FOR 5 SECONDS Once you’re done, the solar inverter will flash blue shortly and will initiate a factory reset and a reboot which will take a few seconds. After the device is booted up again, you will see that there is a HF-A11x_AP WiFi network available in your App or if you check from your computer’s network settings.

    Web interface configuration

    Connect to your device’s WiFi access point First, connect your laptop or desktop computer to the solar inverter’s WiFi access point – its SSID will be CS- or HF-A11x_AP if you’ve done the factory reset. After connecting to this interface you will temporary lose internet access, as you’ll be connected directly to your solar panel’s micro-inverter. Now open a new tab or window in your web browser and enter the url . You will be asked for a username and password – they are admin / admin. Press “Sign in” and you will be taken to the CraftStrom micro-inverter’s web interface which we will next use to set the correct preferences.

    II. STA interface settings

    Next in the STA Interface Setting section (you can skip the AP Interface Setting section) press “Search” and choose your home WiFi network from the list. Note that your network needs to be configured as a 2.5 GHz WiFi network. If it isn’t, please consult your network administrator to enable this WiFi frequency. After selecting your WiFi network from the list, you will be asked to enter the pass phrase. Enter your home WiFi password into this field and press “Apply” below STA Interface Parameters. The security settings will be configured correctly automatically, so you don’t need to change them.

You’ll need internet access for the next step.

    Register your device

    After you have correctly connected your CraftStrom solar panel to the internet, please register your device on our registration website using your CraftStrom email and password (that you chose when creating your account in the CraftStrom mobile app). You can read the device ID from the barcode sticker on your solar panel’s micro-inverter. This registration tells our server to which account your new CraftStrom solar panel belongs to, so that we can help you visualise your solar power generation data in your CraftStrom mobile app. Finishing up If you followed all the steps successfully, you should see the data in your mobile app shortly after your solar panel starts generating power. Congratulations! If you experience any issues, please contact our customer support and we will hopefully sort everything out.
