Decommissioning an Encharge;Enpower While Replacing it On Site

This document outlines the commissioning process for Enphase Ensemble systems, focusing on the Installer Toolkit communications phase. It is intended for Ensemble-certified installation professionals. The overall commissioning process involves two main phases: Installer Toolkit communications and Functional Testing. This document specifically details the steps for establishing successful communication between Ensemble components.

Function Description:

The Enphase Ensemble system is a comprehensive energy solution that integrates solar PV generation with battery storage. The commissioning process, facilitated by the Installer Toolkit, ensures that all components communicate effectively and the system operates as intended. The Installer Toolkit acts as the primary interface for installers to configure, monitor, and manage Ensemble systems. It allows for the scanning and provisioning of devices, updating firmware, setting utility tariffs, configuring metering, and generating summary reports. The system is designed to provide reliable power, including microgrid capabilities during grid outages, and optimize energy usage through various operational modes like self-consumption and savings.

Important Technical Specifications:

Installer Toolkit Versions: Requires Installer Toolkit version 3.X or later for use with Encharge storage systems. Legacy Installer Toolkit 2.0 is not compatible with Encharge.
Envoy Software: The Enphase Envoy must have software version 6.0.X or later for commissioning and operation. Firmware updates are performed via the Installer Toolkit.
Encharge Battery State of Charge (Shipping): Encharge batteries ship with approximately 30% state of charge.
Encharge Battery Default Mode: Encharge batteries ship with "self-consumption" as their default mode.
Communication Protocols: Utilizes Bluetooth Low Energy (BLE) for initial device discovery and network information exchange, and 2.4 GHz radio for communication between the Envoy and Encharge/Enpower units. WiFi and Ethernet are used for Envoy internet connectivity.
Enphase Mobile Connect Modem: Ensemble installations require a cellular modem (LTE-M cell modem) plugged into the Envoy's USB terminals for continuous internet connection.
Microgrid Interconnect Device Relay: Requires 60-330 seconds for the microgrid interconnect device relay to close during power-on sequences.
Encharge LED Indicators: LEDs flash red during certain power-on sequences and stop flashing when DC switches are turned ON, indicating proper operation.
Firmware Update Duration: Envoy firmware updates take approximately 30 minutes. Encharge battery firmware upgrades can take between 4-12 hours, depending on the quantity of batteries.
System Metrics Display: Installer Toolkit takes approximately 10 minutes to correctly display system metrics (including web connectivity) after an Envoy reboot.

Usage Features:

Mobile Application Interface: The Installer Toolkit is a mobile application available on iOS and Android platforms, enabling on-site commissioning using a smartphone or tablet.
Bluetooth Connectivity: Requires Bluetooth to be enabled on the smart device for communication with Ensemble components.
Automatic Sleep Mode Management: Installers are advised to turn OFF automatic sleep mode (e.g., "Auto Lock" on iOS, "screen saver" on Android) on their smart device to prevent interruptions during firmware upgrades.
System Activation: System activation can be created beforehand using Enlighten Manager or on-site using Installer Toolkit, requiring internet access for on-site activation.
Envoy Software Download: Envoy software can be downloaded to the phone via the Installer Toolkit's Settings tab, requiring a stable WiFi connection.
Device Scanning and Provisioning:
- Enpower and Encharge serial numbers must be manually scanned.
- PV microinverters can be scanned via power line scan, though manual scanning is strongly recommended to avoid "poaching" incorrect serial numbers from nearby sites.
- The Installer Toolkit guides users through provisioning steps, including grid profile updates, tariff settings, and device communication establishment.
Utility Tariff Configuration: Allows selection between single rate (flat) and Time of Use (ToU) rate structures. This automatically sets the battery mode to self-consumption (for single rate) or savings (for ToU).
Envoy Connectivity Management: Guides installers through connecting their phone to the Envoy via AP Mode, configuring WiFi, Ethernet, or cellular internet connectivity for the Envoy.
Certified Installer Requirement: Provisioning Ensemble devices requires the installer to be Ensemble training certified or to select a certified user from their company.
COMMS-KIT-01 Requirement: The Enphase communications kit (COMMS-KIT-01) must be plugged into one of the Envoy USB ports for successful device provisioning.
Power Cycling Procedures: Detailed steps are provided for power cycling Encharge batteries and the Enpower unit if communication issues arise.
Battery Mode Setting: After commissioning, the battery mode should be set to "Full backup" to allow batteries to charge to 100% from the grid for calibration. This can be done via the Enlighten homeowner app or Enlighten Manager web interface.
Production and Consumption CT Configuration: The Installer Toolkit includes a meter wizard to configure Current Transformers (CTs), allowing verification of readings and selection of meter location (solar + load or load only).
Summary Report Generation: The toolkit can generate a summary report with details of provisioned devices and system status, which can be shared via email, text, or Airdrop.
Device Decommissioning: Provides a process for deleting old Encharge or Enpower units from the system when replacing them on-site, ensuring proper system configuration.

Maintenance Features:

Firmware Updates: The Installer Toolkit facilitates firmware updates for the Envoy and Encharge batteries, crucial for maintaining system performance and compatibility.
Troubleshooting Guidance: The document provides specific troubleshooting steps for common issues, such as communication failures (e.g., power cycling batteries/Enpower, reconnecting to Envoy AP mode).
Safety Instructions: Emphasizes adherence to safety instructions and quick install guides for all products, particularly regarding electrical shock hazards and correct wiring.
Wiring Verification: Includes steps for checking correct wiring, such as measuring Encharge chassis metal to ground for AC voltage, to prevent safety hazards.
Calibration: The "Full backup" mode helps calibrate system data in Enlighten by ensuring batteries reach 100% SOC and remain there for 2 hours.
Functional Testing Checklist: Refers to a separate "Ensemble Commissioning: Functional Testing Tech Brief" for a checklist of steps to ensure grid up, grid down, and transition states behave as expected.
