3.2 Electrical Connections
Refer to the connection ports on the rear of the inverter for wiring. Ensure all connections are secure and correctly polarized. Use appropriate gauge wiring for all connections to prevent overheating and ensure efficient power transfer.
- PV Input: Connect your solar panel array to the PV IN+ and PV IN- terminals. The inverter supports a wide PV array voltage range of 60-500VDC.
- Battery Connection: Connect your 48V battery bank to the designated battery terminals. The inverter supports BMS communication via RS485, CAN-BUS, or RS232 ports.
- AC Input: Connect the utility grid AC power to the AC INPUT terminals. An input breaker is provided.
- AC Output: Connect your loads to the Dual AC OUTPUT 1 and AC OUTPUT 2 terminals.
- Communication Ports: Utilize USB, RS232, RS485 (BMS), WiFi, and Dry-contact ports for monitoring and advanced control.

4.3 Charging Modes
The inverter offers user-configurable AC/Solar Charging modes and Load Output modes to optimize power usage. You can select from four primary charging modes:
- Solar Charging: Prioritizes solar power for charging batteries and powering loads.
- Electricity Utility Priority: Prioritizes utility grid power.
- Solar Priority: Prioritizes solar power, using utility only when solar is insufficient.
- Hybrid Charging: Combines solar and utility power for optimal charging and load support.

4.5 Mobile Monitoring
Utilize the built-in WiFi and the available mobile application for remote monitoring of your inverter's performance and system status.
5. Maintenance
The Sako Hybrid Inverter is designed for minimal maintenance. However, regular checks can ensure its longevity and optimal performance.
- Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Do not use liquid cleaners.
- Ventilation: Ensure that the ventilation openings are clear of dust and debris to prevent overheating. The built-in anti-dust kit helps reduce dust accumulation.
- Connections: Annually check all electrical connections for tightness and signs of corrosion.
- Battery Health: If using batteries, monitor their health and ensure the battery equalization feature is active to extend their lifespan.
6. Troubleshooting
This section provides general guidance for common issues. For complex problems, please contact customer support.
- No Power Output: Check input power from solar panels and utility grid. Verify battery connections and charge level. Ensure all breakers are in the ON position.
- Inverter Overheating: Check for obstructions around ventilation openings. Ensure the ambient temperature is within the specified operating range.
- Error Codes: Refer to the inverter's LCD display for specific error codes. Consult the detailed product manual (if available) or contact support with the error code for assistance.
