ShinePhone APP Interface Example:

The APP interface allows setting parameters like Operation Mode, Battery Management, System Default Output Power, Temperature Unit, and Currency. It also displays Device Name and Firmware Version.

Connect ShinePhone APP

Use the ShinePhone application to remotely monitor and control your NEXA 2000 All-in-one Balcony Solar Storage system.

Create A Power Plant

1. Scan the QR code or search for 'ShinePhone' on the App Store or Google Play to download the APP.
2. Click "Register" to create an account.
3. Create a power plant by setting the time, location, PV capacity, and grid electricity price information.

Configure Network

1. Navigate to the "Plant" page from the bottom menu.
2. Click the "+" button in the upper right corner, select "Add device", scroll down, and choose "Balcony Solar Storage".
3. Click "NEXA 2000" and follow the on-app instructions to complete the network configuration and add the device to the power plant.

Note on Re-pairing: If the product 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

The system offers three working modes:

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

Note: The default mode is Load First, with a default system output power of 200W, adjustable via the APP.

Users can click "Add time" to set specific time periods and select a work mode for each period.

Other Important Settings

• Associated Inverter: Link the inverter for system management.
• 7. On-grid Status: Enable for on-grid status, disable for off-grid status.
• 8. Power+ Function: Adjust the maximum grid-connected output power (use with caution).
• 9. Export Limit Function: Requires a wireless meter. Limits the feed power to the grid (0% means no feed, 10% means maximum 10% feed).

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:

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