HJ-6548 6.5kW Off-Grid Hybrid Solar Inverter with Pure Sine Wave 100A MPPT Charger and 10ms UPS Transfer
HJ‑6548 (6.5kW) – Off‑Grid Hybrid Solar Inverter
The HJ‑6548 is a high-performance off-grid hybrid solar inverter designed for residential, workshop, and remote applications where grid power is unreliable or unavailable. Available in 6.5kW rated output with double surge capacity, it provides clean pure sine wave AC power for all types of loads - from LED lights and computers to well pumps, air conditioners, and power tools.
A wide PV input range (40‑500 VDC) allows flexible solar string configurations, while the built-in 100A MPPT solar charger extracts maximum energy from your panels. The 10 ms UPS-grade transfer time ensures seamless switchover during grid outages, protecting sensitive electronics.
With WiFi monitoring, BMS communication (CAN/RS485) for lithium batteries, dual AC outputs for load management, and a removable dust cover for harsh environments, this inverter offers a complete energy solution for off-grid living, backup power, or self-consumption.
Key Features & Benefits
- Pure Sine Wave Output - Clean, stable power (voltage THD <3%) compatible with all appliances, motors, and sensitive electronics
- High Surge Capacity - 12kVA surge for starting heavy loads like refrigerators, pumps, and compressors
- Wide PV Input (40‑500 VDC) - Connect higher voltage solar strings (up to ~450V open circuit) to reduce cable losses and avoid combiner boxes
- Built-in High-Current MPPT - 100A solar charger for fast battery charging even with limited sun
- 10 ms UPS Transfer Time - Uninterrupted power for computers, servers, and medical devices during grid failure (also selectable 20 ms generator mode)
- Dual AC Outputs - Programmable outputs allow you to separate critical loads from non-critical loads, shedding the latter when battery is low
- Lithium & Lead-Acid Compatible - Supports user-adjustable charging parameters; BMS communication for lithium batteries with automatic protocol detection
- Integrated WiFi Monitoring - Real-time data and remote control via free smartphone app (iOS/Android)
- Removable Dust Cover - Protects electronics in dusty workshops or barns; easy to remove for cleaning or maintenance
- Wide AC Input Range - Accepts grid or generator from 90‑280VAC (normal mode) or 170‑280VAC (UPS mode), auto-sensing 50/60Hz
- BMS Communication Ready - Standard CAN/RS485 ports for seamless integration with lithium batteries
Applications
- Off-Grid Homes & Cabins - Complete solar + battery system for 24/7 power independent of the grid
