Built for U.S. 120V Home Backup
The SGR-6.5KW-U is designed for U.S. home backup applications with 120V output from a single unit. This makes it suitable for common household backup loads such as refrigerators, lights, routers, TVs, laptops, microwaves, and small appliances.
Power the Essentials You Use Every Day
Keep refrigerators, lights, Wi-Fi, home-office equipment, TVs, and other everyday appliances running during an outage. With 6500W continuous output and up to 12000VA peak power, it can handle many common household loads and their startup demands.
What You Need for a Complete Backup System
Pair the SGR-6.5KW with a compatible 48V battery bank and properly sized solar panels. Battery capacity determines backup runtime, while solar array size affects charging speed and daily energy production. Professional installation is recommended for safe wiring and code-compliant system setup.
Capture More Solar with Dual MPPT Inputs
Connect two independent solar strings with up to 4,500W per MPPT and 9,000W total PV input, giving you more flexibility for different roof sections, panel orientations, and solar array designs.
Smarter Charging for Every Backup Scenario
Choose the right power strategy for your home. Use solar first to save more energy, rely on grid power when stability matters, or combine solar and grid charging for faster battery recovery before storms, outages, or low-solar days.
Easy LCD Control and Real-Time Monitoring
The built-in LCD screen makes it easier for users and installers to view system information, adjust key settings, and select operating modes directly from the inverter.
Real-Time Data Monitoring
View system status, voltage, battery information, charging status, load condition, and fault alerts.

Safety & Installation Note
The EASUN SGR-6.5KW-U is a high-power electrical device and should be installed by a qualified electrician or solar professional. Proper installation helps ensure correct breaker sizing, battery protection, PV string design, grounding, transfer switching, communication wiring, and local electrical code compliance.
A single unit provides 120V output. For 120/240V split-phase applications, two compatible units are required and must be configured correctly according to the official manual.
Backup power requires a compatible 48V battery bank. Battery and solar panels are sold separately unless included in a specific bundle.
Always confirm battery settings, PV voltage limits, charging current, wiring size, breaker protection, ventilation clearance, and grounding before operation.
