Product Introduction

Function

The EcoFlow PowerGlow is a water heating device for grid-connected photovoltaic systems like EcoFlow PowerOcean or third-party PV systems. When integrated with EcoFlow PowerOcean, battery charging has priority. Surplus PV energy is used for hot water heating, with intelligent scheduling via the EcoFlow App. This improves self-consumption and self-sufficiency rates, reducing electricity and gas costs.

Integration with EcoFlow PowerOcean System

Diagram Description: A PV string connects to an EcoFlow PowerOcean Hybrid Inverter. This inverter is linked to an EcoFlow PowerOcean LFP Battery and the EcoFlow PowerGlow. The system also connects to the utility grid via a router and smart meter, with options for controllable and non-controllable loads.

Integration with EcoFlow PowerOcean DC FIT System

Diagram Description: A PV string connects to a PV Inverter, which then feeds into an EcoFlow PowerOcean PV Storage Converter. This converter interfaces with an EcoFlow PowerOcean LFP Battery and the EcoFlow PowerGlow, connecting to a router, internet, and the utility grid.

Integration with Third-Party PV System

Diagram Description: A PV string connects directly to a Third-Party PV Inverter, which then connects to the EcoFlow PowerGlow.

Working Principles

The EcoFlow PowerGlow Smart Immersion Heater uses an electrical resistant heating element encased in a sheath. When energized by AC power (converted from PV excess), it heats the water in the tank.

Label Description

ENCLOSURE LABELS:

Appearance

The EcoFlow PowerGlow features a main unit with a WiFi Antenna, Power Switch, and Temperature Adjustment Knob. A heating rod extends from the unit. Connection ports include WAN, WiFi, RS485, RELAY, and TEMP SENSOR. An AC IN port is also present. Warnings are noted for the AC breaker (rated current 32A, not included, must be configured at the AC IN connector) and a reserved SELV Relay (potential-free switching contact for safety extra-low voltage; do not connect mains voltage).

System Operation

System Power-On

Procedure (Integrated with PowerOcean)

1. Power on the PowerOcean system (refer to its installation guide).
2. Power on the AC breaker/RCD connected to the device.
3. Set the POWER SWITCH to 'I' (ON).
4. Observe the LCD display for operating status (real-time water temperature).

Procedure (Integrated with Third-Party PV System)

1. Power on the third-party PV system.
2. Power on the AC breaker/RCD connected to the device.
3. Set the POWER SWITCH to 'I' (ON).
4. Observe the LCD display for operating status (real-time water temperature).

NOTICE: During initial commissioning, press the knob or send a power-on command via EcoFlow app to activate heating mode.

LCD Display

The LCD display shows various statuses:

• 88℃ (blinking): Startup, indicating real-time water temperature.
• 88℃ (steady): Indicates a desired water temperature when rotating the Temperature Adjustment Knob.
• 88℃ (blinking twice): Confirms temperature setting after pressing the knob.
• E-: Indicates a faulty status.
• U: Over-the-air update in progress.
• --: Not connected to network.
• Network failure: Indicates a network issue.
• Power off: Device is powered off.

NOTICE: If the LCD indicates a faulty status, visit the EcoFlow app for error codes and troubleshooting.

Setting Temperature

Method 1: Via Temperature Adjustment Knob

Rotate the Temperature Adjustment Knob until the desired temperature is displayed on the LCD, then press the knob once to complete the setting. The digits will blink twice.

Method 2: Via EcoFlow App

Refer to the App Control section in the installation guide.

Setting Manual Mode

Manual mode is for times/areas with insufficient power from PV strings. The PowerGlow operates at the set power, drawing from grid and solar, even without surplus solar power, allowing heating even in low light.

Example: Weak sunlight (110 W surplus PV), PowerGlow consumes 8438 W, drawing 8328 W from the grid.

Setting Smart Mode

Smart mode is for times/areas with sufficient power from PV strings. The PowerGlow switches between solar and grid power based on meter data, maximizing solar utilization and minimizing grid draw. It can even feed 0 W to the grid.

Example: Sufficient sunlight (8007 W surplus PV), PowerGlow consumes 8007 W, drawing 0 W from the grid.

In Smart mode, you can set up to two scheduled heating tasks. If sunlight is insufficient, it draws power from both solar and grid to reach the set temperature within the scheduled time.

NOTICE: If used without EcoFlow App, water tank capacity defaults to 0 L, and the PowerGlow operates at maximum power.

Scheduled Tank Sterilization

During scheduled disinfection, the PowerGlow operates at rated power and automatically switches back to the set mode afterwards, avoiding unnecessary grid power consumption. It heats water to 75°C for 3 minutes. Disinfection starts at a set time and can repeat daily or weekly.

Maintenance

Self Check Function

The EcoFlow PowerGlow has a self-check function to prevent dry burning. After a power outage or shutdown, it performs a 2-3 minute self-check. Heating mode cannot be switched during this period. Once complete, it resumes operation.

WARNING: Do not attempt to turn the PowerGlow on or off during self-check to avoid damage. Ensure heating elements are always submerged in water; never use in dry mode.

System Power-Off

WARNING: Always disconnect from all power before installing, operating, or maintaining.

The POWER SWITCH only enables/disables heating. To fully de-energize, power off the AC breaker/RCD connected to the device.

Procedure (Integrated with PowerOcean):

1. Set POWER SWITCH to 'O' (OFF).
2. Power off the AC breaker/RCD.
3. Power off the PowerOcean system (refer to its installation guide).
4. Ensure the LCD display is off.

Procedure (Integrated with Third-Party PV System):

1. Set POWER SWITCH to 'O' (OFF).
2. Power off the AC breaker/RCD.
3. Power off the third-party PV system.
4. Ensure the LCD display is off.

Routine Maintenance

WARNING: Always disconnect from all power before any operation. Wear proper PPE.

1. Set POWER SWITCH to 'O' (OFF).
2. Turn the control thermostat knob to the full left position.
3. Place warning signs or erect fences to prevent unauthorized access.
4. If the equipment is faulty, contact your dealer.
5. The equipment can only be powered on after all faults are rectified.

Troubleshooting

WARNING: Only qualified professionals should perform troubleshooting. Wear proper PPE.

1. Visit and log in to the EcoFlow App.
2. Retrieve the error code and follow in-app instructions.
3. Completely power off the entire system (see System Power-Off).
