Note for Re-pairing: If the device is already bound to a mobile device, press the device's IoT button for 3 seconds to unpair it before re-pairing with a new mobile device.

Set Operation Mode

6.1 Click "Add time", add a time period, and select a work mode for that time period.

• Load First Mode: Prioritizes photovoltaic power for the load. Excess energy is stored in the battery. If photovoltaic energy is insufficient, the battery discharges to supplement.
• Battery First Mode: Prioritizes charging the battery until its upper limit SOC. Discharging stops then. If the battery is fully charged and photovoltaic energy is still available, it outputs according to the photovoltaic power.
• Smart Self-consumption Mode: Available only when connected to a smart meter. The smart meter monitors home power consumption and intelligently adjusts system output.

Note: The default is Load First Mode with a system output power of 200W. This can be adjusted in the APP.

6.2 Click on the "?" icon in the upper right corner to view detailed operating instructions.

Other Important Settings

• Associated inverter: Link to inverter settings.
• 7. On-grid Status: Enable for on-grid status, disable for off-grid status.
• 8. Power+ Function: Adjusts the maximum grid-connected output. Use with caution.
• 9. Export Limit Function: Limits feed power when associated with a wireless meter. 0% means no feed to the grid; 10% means a maximum feed of 10%.

Cold-start

When the battery temperature is between -30°C and -20°C, connecting solar panels with photovoltaic input can automatically heat the battery to the working temperature, allowing the NEXA 2000 to function normally in low-temperature environments.

Note:

1. Estimated remaining heating time is based on maximum heating power (PV input ≥140W) and is for reference only. The heating function stops when the battery temperature reaches 5℃.
2. Remaining heating time is the time to heat from the current temperature to 5°C.
3. If the NEXA 2000 is below 0°C and the photovoltaic input power is ≤140W, photovoltaic energy is prioritized for battery heating.

FAQ

Q1: Does NEXA 2000 support simultaneous charging and discharging?

Yes, the input/output ports are different, allowing simultaneous charging and discharging.

Q2: Is it possible to charge NEXA 2000 with solar panels from other brands?

Yes, provided they meet the photovoltaic charging specifications of this product.

Q3: How to store my NEXA 2000?

For long-term storage, fully charge the machine, disconnect the photovoltaic connection, and turn off the machine. Charge and discharge the product every 3 months: discharge to 20%, then charge to 80%.

Q4: Can one battery be connected to four solar panels?

Yes, you can use the Y-Branch Solar Parallel Cable to connect 4 solar panels.

Q5: What is the waterproof performance of this device?

NEXA 2000 has an IP66 rating, making it suitable for outdoor use in challenging conditions, including dusty environments or rain showers.

Q6: How to monitor the electricity generation of NEXA 2000 All-in-one Solar Balcony Storage system?

Use the ShinePhone app to monitor solar power generation data and regulate the system's real-time output power.

Q7: How does NEXA 2000 All-in-one Solar Balcony Storage operate?

NEXA 2000 supports three working modes: Load First Mode, Battery First Mode, and Smart Self-Consumption Mode. Users can set different modes for different time periods.

The system operates on Load First mode by default, prioritizing photovoltaic power for the load. Excess energy is stored in the battery. If photovoltaic energy is insufficient, the battery discharges to supplement. The default system output power is 200W, adjustable via the app.

Battery First mode prioritizes charging the battery until its upper limit SOC, then stops discharging. If the battery is fully charged and photovoltaic energy is available, it outputs according to the photovoltaic power.

Smart Self-consumption Mode requires a smart meter to monitor home power consumption and adjust system output accordingly.

Q8: What precautions should I take before installing/adding an extended battery?

The system must be turned off before installing/adding an extended battery. Failure to do so may void the warranty. Follow these steps:

1. Disconnect the NEXA 2000 from the solar panel.
2. Press and hold the On/Off button for 1 second to switch off the power.
3. After powering off, install the extended battery onto the NEXA 2000.
4. Connect the solar panel for normal use.

Q9: What other precautions should I take when installing and using this product?

Ensure the AC power outlet is well grounded. If the PE of the 'Receptacle, Grid Connector' cannot be conducted, use the reserved grounding hole on the chassis for additional grounding.

Q10: How to switch Off-grid mode?

Long press the device Mode Switch Button or use the APP setting page to switch to Off-grid mode.
