FAQs
Is the EG4 3K compatible with my solar panels?
Yes, the EG4 3K Off-Grid Inverter is compatible with a wide range of solar panels. It supports up to 145V DC input and is designed to work efficiently with standard solar arrays. Your installer will help determine the best panel configuration based on your setup and energy needs.
Do I need a battery to use the EG4 3K?
Yes, the EG4 3K is an off-grid inverter and requires a battery bank to operate. It does not function as a grid-tied inverter and relies on batteries to store and supply power to your home or cabin.
How do I monitor the performance of my EG4 3K?
The EG4 3K features an integrated LCD display for local monitoring and basic configuration. For remote monitoring, it may support RS485/USB communication ports (depending on the firmware and accessories used). Consult the user manual or speak with your installer for remote monitoring options.
What happens if there is a power outage?
Since the EG4 3K is an off-grid inverter, it operates independently from the utility grid. Power outages do not affect its operation. As long as your battery bank has sufficient charge and solar panels are generating energy, the inverter will continue to power your essential loads.
How do I maintain the EG4 3K?
Maintenance for the EG4 3K is minimal. Periodically check the system for any error codes or alarms on the LCD screen, ensure the unit is clean and well-ventilated, and monitor battery health. Your installer may recommend an occasional system checkup depending on usage.
What is the efficiency of the EG4 3K Off-Grid Inverter?
The EG4 3K inverter offers high conversion efficiency—typically around 93% to 95%. Refer to the product datasheet or manual for precise efficiency ratings based on usage conditions.
What are the input and output voltage ranges?
The EG4 3K supports a PV input voltage range of up to 145V DC and outputs 120V AC (single-phase). It’s designed for 24V battery systems. For full technical details, consult the official EG4 datasheet or installation guide.
What communication protocols does the EG4 3K use?
The inverter typically uses RS485 or USB for communication. Depending on your system configuration, optional modules may allow for more advanced monitoring or integration with battery management systems. Please refer to the product manual for supported communication protocols.
