1. Product Overview
The Srne SPI-6.5K-UP is a US Version 6.5KW 48V Hybrid Solar Inverter designed for off-grid split-phase solar power systems. It converts DC power from solar panels and batteries into 120V/240V AC power for household loads. This inverter integrates a solar charge controller, inverter, and battery charger into one unit to offer uninterruptible power support.
2. Installation and Setup
This inverter is designed for indoor use only (IP20 protection degree). Ensure the installation location is dry, well-ventilated, and free from direct sunlight or excessive heat sources. Proper clearance around the unit is necessary for adequate cooling.
2.1 Physical Installation
Mount the inverter securely on a vertical surface. Ensure the mounting hardware is appropriate for the inverter's weight (23kg) and the wall material.
2.2 Wiring Connections
All wiring should be performed by a qualified electrician in accordance with local electrical codes. Refer to the diagram below for connection points.
- PV Input: Connect solar panel arrays to the PV terminals. The inverter supports two Maximum Power Point Tracking (MPPT) inputs.
- Battery Input: Connect a 48Vdc battery bank (Li-ion, Lead-Acid, or User Defined) to the BAT terminals.
- GRID Input: Connect the utility grid power to the GRID terminals.
- LOAD Output: Connect your household loads (120/240Vac split phase) to the LOAD terminals.
- GEN Input: Connect a generator to the GEN terminals if used as an auxiliary power source.
- Communication Ports: Utilize RS485, CAN, or USB for local monitoring. External Wifi/GPRS modules can be connected for remote monitoring.
- Parallel Connection: The inverter supports parallel operation for increased capacity, indicated by the 'PARALLEL CONNECTION' port.
3. Operating Instructions
3.1 Powering On/Off
- Ensure all wiring connections are secure and correct.
- Turn on the battery breaker first.
- Turn on the PV array breaker (if applicable).
- Turn on the AC input breaker (utility grid or generator, if applicable).
- Switch the inverter's ON/OFF button to the 'ON' position. The display will illuminate, and the inverter will begin its startup sequence.
- To power off, reverse the sequence: turn off the inverter, then AC input, then PV, and finally the battery.
3.2 Display and Monitoring
The inverter features an integrated display for real-time monitoring of system status, input/output voltages, charging currents, and other operational parameters. Navigate through the display menus using the buttons located next to the screen.
For advanced monitoring and control, connect to the inverter via the built-in RS485, CAN, or USB interfaces. Optional Wifi/GPRS external modules allow for remote monitoring through a dedicated application or web portal.
4. Maintenance
Regular maintenance ensures optimal performance and longevity of your inverter.
- Cleaning: Keep the inverter's exterior clean and free from dust. Use a dry cloth for cleaning.
- Ventilation: Ensure the internal fan and ventilation openings (as shown in Figure 2) are not blocked. Proper airflow is crucial for cooling.
- Connections: Periodically check all wiring connections for tightness and signs of corrosion.
- Environment: As the inverter has an IP20 rating, it is designed for indoor use only. Protect it from moisture, direct water exposure, and extreme temperatures.
5. Troubleshooting
If you encounter any issues with your Srne SPI-6.5K-UP inverter, please refer to the following general guidelines. For complex problems, contact technical support.
- No Power Output: Check all input sources (PV, Grid, Battery) and ensure they are supplying power. Verify all breakers and switches are in the 'ON' position. Check for any error codes on the inverter display.
- Inverter Overload: If the inverter shuts down due to overload, reduce the connected load. The inverter has a maximum peak power of 13000VA.
- Battery Not Charging: Ensure PV panels are receiving sufficient sunlight and are correctly connected. Check battery voltage and health.
- Communication Issues: Verify cable connections for RS485/CAN/USB. For Wifi/GPRS, ensure the external module is correctly installed and configured.
