Box contents
Both kits include:
- NeoCharge Energy Monitor, with the back-label card (serial number and installer PIN)
- Two branch 50 A current transformers (CTs) with 22 AWG leads and screw-terminal plugs, for ports 3 and 4
- Voltage harness: 7.6 mm screw-terminal plug with four 16 AWG leads (black L1, red L2, white N, blue L3)
- Wi-Fi antenna assembly with knockout plug
Split-core CT kit
Also in the box:
- Two main 200 A split-core CTs with 22 AWG leads and screw-terminal plugs, for ports 1 and 2
- Wire nuts and splicing wires
Flex (Rogowski) kit
Also in the box:
- Two flexible Rogowski coils, each with an integrator and a twisted signal cable, for ports 1 and 2
- One 12 V sensor power supply: black and red 12 V output split to two signal wires (each with a 4-pin plug for an integrator and a 2-pin plug for port 1 or 2), and a black + white AC input (black to L1, white to L2)
- Two 5-port Wago lever connectors, two wire nuts, and black and red splicing wires
Use production kits only: the harness, power supply and integrators as shipped. Don't mix in parts from sample kits. More in Flexible (Rogowski) sensors.
Monitor connections
- Top: four sensor ports, numbered 1, 2, 3, 4.
- Right side: the voltage harness port (L1, L2, N, L3).
- Left side: the Wi-Fi antenna coax connector and the RJ45 Ethernet port.
- Front: the status light. See Status light.
- Bottom: the hardware reset button.
Port map
| Port | Sensor | Goes on |
|---|---|---|
| 1 | Main sensor (200 A CT or flex coil via integrator) | L1 of the breaker the EMS protects (L1 recommended, not required) |
| 2 | Main sensor (200 A CT or flex coil via integrator) | L2 of the same breaker |
| 3 | Branch 50 A CT | A battery or solar line, the Autel's second leg, or one other load |
| 4 | Branch 50 A CT | The EV charger (Autel), always |
Danger
Ports 1 and 2 are mains only. The app enforces this. Never put a branch CT in port 1 or 2, or a main sensor in port 3 or 4. On one early install the swap made the charger read as the mains; the EMS paused charging every minute and it took a revisit to fix.
Voltage harness
| Lead | Role | Connect to |
|---|---|---|
| Black (L1) | Powers the monitor and gives the voltage reference for phase A | Required on every install. A breaker pole |
| Red (L2) | Voltage reference for phase B (split-phase 240 V) | The other pole: the stacked breaker directly above or below, or the second pole of a 2-pole breaker. Leave it off only on a single-phase 120 V service |
| White (N) | Neutral | Required on every install. The neutral bus bar (except on an AFCI/GFCI breaker, see Step 5) |
| Blue (L3) | Third phase, or battery direction reference | 3-phase 208Y/120 V: the third phase. Split-phase: splice to L1 only when CT 3 monitors a battery. Otherwise cap it |
The Energy Monitor is Class II (double-insulated) and doesn't need a ground wire, so one slot on the voltage harness plug is empty.
Warning
L2 and L3 are voltage sensing only. Connect them to hot (line) conductors only, never to neutral.
