Welcome to the SMA Energy Meter Guide
welcome to this streamlined guide for the SMA energy meter your path to mastering intelligent Energy Management we'll navigate you through setting up the energy meter on a split phase system streamlining the entire installation process ready to enhance your expertise let's get started
when opening the box you'll have the SMA energy meter attached to it is the magnetic mounting adapter you'll also have the power cable that's 3 ft long a box that includes two current Transformers or CTS which are 4 ft long the manual 120 Ohm resistor and two rs485 connectors

Installation Overview
now let's learn how to install the energy meter on a split face system
Mounting the Energy Meter
first make sure the electric panel is Switched Off before removing its cover the energy meter comes with attached mounting adapter which can't be detached if necessary press this tab and lift it away to reattach the adapter simply slide it back into place like so remove the adhesive tape and select a suitable location to mount the energy meter notice that you can mount the energy meter in these orientations as well
Current Transformer (CT) Connections
let's start with the CTS connect the CT cable to the energy meter the CT wire on one and two must go on line one of the panel while the CT wire on three and four must go on line two of the panel the arrows on the CTS must Point towards the utility review the CT label for its rating open the clamp of the CT designated for line one and secure it around line one in the panel then clamp the CT for line two making sure both cat ts are oriented to face towards the utility for accurate energy flow measurement
Power Cable Connections
now let's move on to the power cable connect the power cable to the energy meter by plugging it in securely just like so next attach the neutral wire to the neutral bus bar for the black wire connected to a vacant L1 circuit breaker suitable for either 120 volt or 240 volt systems and finally connect the red wire to an available line 2 circuit breaker
Data Connectivity and Commissioning
next connect a 300 volt rated shielded cat 56 cable from the front of the energy meter and to the inverter or the home router this is the preferred method Al alternatively you can connect the energy meter to the sunny boy Smart Energy via rs485 as a backup option
that does complete the installation of the energy meter the next steps require that you commission the system with a 360 app we hope you found this video demonstration helpful visit sm- am.com for more resources thanks for watching
Frequently Asked Questions
Q: How do I mount the SMA energy meter?
