NRGpilot E3000 Net Meter Installation Guide
Introduction
Fig 1 Typical connection for NRGpilot E3000 Meter
NRGpilotTM separately measures the power and energy from local solar
generation and the grid. It uses these values to calculate power and energy
consumed by building loads. Cachelan provides one NRGpilot E3000 meter
with split-core CTs for data collection and sending via internet to the
NRGpilot remote servers. The installer must supply fuses, meter enclosure
and installation. NRGpilot displays power and energy for generation, grid
import, grid export and total loads. An option is available to monitor up to 6
individual loads separately. Status and logs display measured values for
identifying grid and equipment issues. Use NRGpilot to understand power
usage, check utility net meter credits and ensure the solar generation system
is working correctly.

ACCESS
NRGpilot is accessed from a browser using data sent over the internet from
the E3000 NRGpilot meter connected to the site network as shown in fig 1.
Connect a standard cat5e patch cable between the NRGpilot meter and the
building router. The LAN must have persistent high speed internet service to
an ISP to provide access to the internet. Alternatively, NRGpilot can be
ordered with a 3G cellular modem for wireless internet connection. In this
case, a 120VAC receptacle is required to plug in the 3G modem power
dongle.

Net Meter Installation
NRGpilot Meter Mounting: Install a suitable enclosure for the E3000 meter
near the main breaker panel. Mount the E3000 meter in the enclosure ready
for connection of the CT secondaries and voltages from the breaker panel.
Fig 2 Device List
Power Supply: The NRGpilot E3000 meter receives control power from the
voltage inputs on terminals L1 and N. No external power supply is required.
Maximum voltage inputs are 480/277. For 600/347 systems, voltage
transformers are required - consult factory for correct settings.
Meter Serial Number:
120/240 single phase
System Configuration:
CT Wiring: The direction of the CTs during installation is very important for
correct meter reading. Refer to fig 3a for 208/120V, 480/277 3 phase and 3b
for 120/240 single phase for CT orientation details. As shown in the figures
ensure the arrow mark on each CT points to the load or generator. Split-core
CTs supplied by Cachelan with a secondary of 333mV are clamped on
around existing wires inside breaker panel. For safety, power should be off
when installing the CTs and wiring the voltage inputs.
CT Allocation: The NRGpilot E3000 meter has 12 CT inputs. Inputs 1 - 3
are reserved for measuring grid power; inputs 4 - 6 are reserved for
generation power from the inverter(s) and inputs 7 - 12 are for optional
individual circuit monitoring. CT configuration is programmed at the factory
to match the order. See documentation supplied for assignment of CT
connections recorded in the CT allocation table. Fig 2 is an example of the
CT assignment for a 120/240V single phase system with no separate load
monitoring. For typical installation wiring, refer to Fig 3a for a 208/120V,
480/277 3-phase 4-wire system and Fig 3b for a 120/240 split-phase 3-wire
system.
If the CT allocation table is not correct or if the configuration needs to be
changed contact Cachelan tech-support at 905.470.8400x224 for remote
configuration update.

Network Setup
The NRGpilot E3000 meter must be plugged into the building LAN router or 3G cellular modem/router for internet access. By default,
each NRGpilot meter is set to DHCP to obtain its IP address from the network router automatically. The Status LED is an installation aid
and can be used to determine the status of internet connectivity. For a static IP connection, consult the factory at time of order.

Testing - Internet
When NRGpilot E3000 meter is first powered up the Status light indicates blinking blue. Wait 1 minute for the power on sequence to
complete. Launch the internet browser from either a smart phone or computer. Enter the NRGpilot portal URL shown on the E3000 meter
label as shown in Fig 5 in the format mysitename.NRGpilot.com. After accessing the NRGpilot portal screen, go to
ANALYZER --> Net Meter and check
1) The meter reading is displayed with actual values in blue
2) Both Last Data Updated and Last Communication indicaotrs should be green and with a timestamp from the last 10 minutes.
If the Last Data Update is red, no data has been received for at least 2 hours and the last received data values are displayed in gray.
In this case check internet connections and network settings.
3) Check that the metered voltages and currents agree with values measured using a DMM to verify wiring is correct.
