4. Setup and Installation

Proper installation is crucial for the inverter's performance and safety. Ensure all local electrical codes and regulations are followed.

4.1 Mounting the Inverter

• Choose a vertical, non-flammable surface.
• Ensure adequate clearance (at least 20 cm) around the inverter for proper ventilation.
• Mount the inverter securely using the provided installation toolkit.

4.2 Wiring Connections

All wiring must be done with the inverter and all power sources (solar panels, batteries, AC grid) disconnected and de-energized. Use appropriate wire gauges as specified in the detailed wiring diagram.

Figure 4.1: Comprehensive wiring diagram for the hybrid inverter system, illustrating connections for solar panels (PV input), AC input from grid/generator, AC output to home loads, and battery bank. Recommended cable gauges and breaker sizes are indicated.

1. Battery Connection: Connect the 48V battery bank to the inverter's battery terminals. Ensure correct polarity. The inverter is compatible with AGM/Gel/Flooded/Lithium batteries.
2. PV Input Connection: Connect your solar panel array to the PV input terminals. Ensure the PV open circuit voltage (Voc) does not exceed 300VDC. Recommended configuration is series connection.
3. AC Input Connection: Connect the AC grid or generator input to the AC input terminals.
4. AC Output Connection: Connect your home loads to the AC output terminals. The rated output is 3600W, 110V/120V.
5. Grounding: Connect the inverter's grounding terminal to a reliable earth ground.

4.3 WiFi Module Setup

The included WiFi module enables remote monitoring of your inverter system via a mobile application. Follow the instructions provided with the WiFi module for registration and setup. This typically involves connecting the module to the inverter's WiFi port and configuring it through the app.

5. Operating Modes

The inverter offers flexible charging and output modes to optimize energy management based on your preferences and system requirements.

5.1 Charger Source Priority

This setting determines how the battery bank is charged from different power sources.

Figure 5.1: Options for prioritizing charging sources for the battery bank.

• Solar First AC Input Next: Prioritizes solar power for charging. AC input charges only when solar power is unavailable.
• Solar and AC Input Simultaneously: Charges the battery from both solar and AC power concurrently.
• Solar Only: The inverter charges the battery exclusively from available solar power.
• Utility Priority (Hybrid): Prioritizes utility power for charging, using solar as a secondary source.

5.2 Output Source Priority

This setting controls how your appliances are powered to avoid interruptions.

Figure 5.2: Options for prioritizing power sources for connected loads.

• Solar First: The inverter uses solar power to supply loads first. If solar input is insufficient, it compensates with AC input.
• AC First: The inverter prioritizes AC input for all loads. DC sources (solar/battery) are used only when AC power is unavailable.
• DC Priority: Prioritizes solar power first. If solar is not enough, the battery bank will supply power. AC input only powers loads when a low-battery warning is triggered.
• Inverter Priority: Prioritizes battery power, using AC input only when battery voltage is low.

5.3 Time Slot Charging & Discharging Function

This feature allows you to schedule charging and discharging times, which is ideal for maximizing PV energy utilization and reducing utility costs in regions with peak/valley electricity tariffs. Refer to the inverter's display or mobile app for configuration options.

6. Parallel Operation

The Anjfylque Hybrid Solar Inverter supports parallel connection of up to 6 units, allowing for scalable power solutions for larger residential or commercial applications. This enables configurations for single-phase, split-phase, or 3-phase systems.
