• High-capacity pure sine wave inverter: Delivers 5500W of continuous power with clean, stable AC output that protects sensitive electronics such as computers, lab equipment, and entertainment systems. The pure sine wave waveform minimizes harmonic distortion, reduces heat, and ensures smooth motor starts for compressors, pumps, and other demanding loads. This results in quieter operation and longer equipment lifespans while maintaining peak performance across a wide range of temperatures and electrical environments.
• 48V DC input and 230V AC output: Optimized for a 48V battery bank, this inverter provides reliable 230V AC across outlets and circuits, enabling compatibility with regional standards worldwide. The 48V–to–AC conversion is designed for efficiency and resilience, supporting both lead-acid and lithium-based 48V battery chemistries when used with proper battery management. This configuration makes it a versatile centerpiece for stationary off-grid homes, remote cabins, or mobile power systems where consistent AC power is essential.
• 90A MPPT solar charge controller: A high-efficiency MPPT controller maximizes solar harvest by continuously adjusting the PV array’s operating voltage to harvest the maximum available power under varying light conditions. The 90A rating supports sizable solar arrays and fast battery charging, helping shorten recharge times after cloudy periods and maintain healthy state-of-charge levels. Temperature-aware charging, multi-string support, and smart battery management contribute to longer battery life and steadier performance during long-duration solar days.
• Parallel operation for expandable capacity: When energy demand grows or you want redundancy, this unit can be paired with additional similar inverters in parallel to increase total usable capacity. Parallel operation enables scalable power systems without sacrificing reliability. You can design modular, expandable microgrids that start with a modest footprint and grow toward higher loads, all while maintaining synchronized output and stable voltage regulation across the system.
• Automatic transfer switching for extended-run UPS capability: The built-in transfer switch detects power interruptions and shifts seamlessly between utility grid, battery, and solar sources. This feature creates an extended-run UPS experience, so essential equipment remains powered during outages or brief grid disturbances. The UPS-like behavior reduces risk for data loss, equipment damage, and downtime, making it an excellent choice for home offices, medical devices, network equipment, and critical tools that require dependable uptime.

How to Install Tripp Lite by Eaton 5500W Solar Inverter/Charger

Installations should be performed by qualified professionals following local electrical codes and the manufacturer’s installation manual. This unit is built for robust, long-term operation in off-grid and backup power configurations, and proper setup is essential to maximize performance and safety.

• Plan your layout: Choose a ventilated, dry location with adequate clearance for airflow and service access. Ensure the mounting surface supports the weight and that there is space for cabling and heat dissipation.
• Prepare the battery connection: Connect the 48V DC battery bank to the inverter’s DC input terminals. Use appropriately rated cables, proper fusing or circuit protection, and correct polarity to prevent damage or safety hazards.
• Attach solar inputs (MPPT): Connect the solar array or hybrid PV strings to the MPPT input according to the manufacturer’s wiring diagrams. Ensure array voltage and current stay within the controller’s safe operating range and that all wiring is compliant with electrical codes.
• Connect the AC path: Wire the 230V AC input to the appropriate source (grid or alternate supply) and connect the inverter’s AC output to the distribution panel or dedicated loads. If you’re using it as an extended UPS, configure the transfer settings to prioritize battery or solar power in the event of an outage.
• Configure protections and tests: Set up overcurrent protection, fuses, and any system-specific parameters. Power on the system and verify voltage readings, MPPT status, and smooth transfer during simulated outages to confirm reliable operation.
