Product Description

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
Workshops & Farm Buildings – Reliable power for tools, lighting, water pumps, and machinery
Backup Power for Home – Keep essential circuits running during blackouts
Remote Telecommunications – Power for base stations, repeaters, and monitoring equipment
Small Business & Shops – Reduce electricity bills by storing cheap off-peak power or solar energy

Frequently Asked Questions

What is the difference between HJ‑6548 and HJ‑12048?

HJ‑6548 has 6.5kW rated output (12kVA surge); HJ‑12048 has 12kW rated output (24kVA surge). Both have the same PV input range and basic features.

What is the PV input voltage range?

40-500 VDC. This allows flexible string designs up to ~450V open circuit.

Can I use the inverter without batteries?

No, this is an off-grid hybrid inverter. A battery bank (lithium or lead-acid) is required for stable operation.

Does it support grid feed-in (net metering)?

No. It accepts AC input (grid/generator) as backup but does not export power to the grid.

What is the transfer time when grid fails?

10 ms in UPS mode – seamless enough to keep computers and sensitive electronics running.
