SRNE HF4850U80-H 5kW Hybrid Inverter/Charger

The SRNE HF4850U80-H is a 5,000W pure sine wave hybrid solar inverter charger for 48V battery systems requiring full off-grid output, integrated MPPT solar charging, and grid or generator backup in a compact transformerless enclosure. At 25.6 lbs. (11.6 kg) and just 5.0 in. deep, it delivers 48V inverter charger performance typically associated with much heavier units—without the bulk of a low-frequency transformer design.

5kW output in a transformerless form factor

Reaching 5,000W of continuous output at 48V typically requires a unit with a bulky low-frequency transformer—adding significant weight and depth. The HF4850U80-H uses a transformerless topology to deliver the same output in a package that is 5.0 in. deep and weighs 25.6 lbs., making it practical for shallow wall cavities, equipment enclosures, and installations where mounting space is tight. The 10,000VA peak rating handles the inrush current of motor-driven loads up to 4 HP—refrigeration compressors, well pumps, and power tools—without requiring an oversized unit.

48V solar charging with programmable source priorities

The integrated MPPT controller accepts PV arrays up to 5,200W at 500Vdc open-circuit voltage, enabling high-voltage series string configurations that avoid combiner boxes and reduce balance-of-system wiring costs. With 80A of maximum solar charging current on a 48V bank, the HF4850U80-H can replenish a large battery bank quickly from solar alone. Multiple programmable charging and load modes allow users to configure solar-first, grid-first, or hybrid simultaneous charging based on energy priorities, utility rate schedules, or generator runtime targets—adapting the system to real-world energy access conditions without manual switching.

Application scenarios

• Off-grid home or cabin on a 48V system: 5kW continuous output with 4 HP motor capacity covers full household loads including well pumps, HVAC, and refrigeration in a wall-mount footprint.
• Grid-tied backup for essential circuits: 10ms transfer time and programmable bypass keep critical loads powered through outages without a separate ATS.
• Space-constrained utility rooms and enclosures: At 5.0 in. deep and under 26 lbs., it fits installations where full-sized inverters cannot be mounted.
• Existing 48V system upgrade: Drop-in hybrid inverter charger for 48V battery banks that need integrated MPPT solar charging without a separate charge controller.

System compatibility

The HF4850U80-H operates on a 48V battery bank across 40–60Vdc and supports lead-acid, lithium-ion, and user-defined battery chemistries. Its single MPPT input accepts arrays up to 500Vdc open-circuit voltage with a 120–450Vdc operating range, supporting long series strings without a combiner box. AC input accepts 90–140VAC at 50/60Hz from grid or generator sources. Communication interfaces include RS485, CAN, USB, and dry contact for BMS and monitoring integration, with an optional Wi-Fi/GPRS module for remote access. This unit is rated IP20 and requires indoor or appropriately enclosed installation; outdoor deployments need a weatherproof housing.

Why choose the SRNE HF4850U80-H?

The SRNE HF4850U80-H is the right choice for 48V system builders who need a cETL UL1741 and CSA-certified 5,000W inverter charger that integrates MPPT solar charging without the weight and depth of a transformer-based design. Its 10,000VA peak output, 80A solar charging current, 500Vdc PV input, and broad certification suite—including IEC 62109, IEC 62040, SAA, and FCC Part 15 Class B—make it a well-credentialed, space-efficient option for residential off-grid and backup installations where a conventional full-sized inverter charger is impractical to mount.
