Description
The SRNE HF4850U80-H is a compact 5kW 48V single-phase off-grid solar storage inverter designed for residential and rural off-grid applications requiring reliable pure sine wave output, high-efficiency solar charging, and flexible battery compatibility.
Key Features
- Pure Sine Wave Output Delivers clean 120Vac single-phase pure sine wave power with a 10ms typical transfer time, suitable for sensitive electronics and 4HP motor loads.
- 80A Solar MPPT Charging Single MPPT channel accepts up to 5,200W of PV array power at up to 500Vdc open-circuit voltage with 99.9% tracking efficiency and an 80A maximum solar charging current.
- Multiple Charging & Load Modes Supports configurable charging source priority and on-load modes to maximize solar self-consumption and minimize reliance on grid or generator power.
- Comprehensive Built-In Protection Includes PV anti-reverse, battery over/under-voltage, output short-circuit, bypass overcurrent, overtemperature, and AC back-fill protection as standard without additional modules.
- Remote Monitoring Support RS485, CAN, USB, and dry contact communication interfaces are standard, with optional Wi-Fi and GPRS modules for remote parameter monitoring and system management.
The HF4850U80-H operates on a 48V battery bus with a voltage range of 40–60Vdc and supports Lead-Acid, Li-ion, and user-defined battery types. Maximum hybrid charging current is 80A with grid and generator charging capped at 40A, and the transformerless design achieves a maximum inverter efficiency of 92%.
Certified to RoHS, EN61000, FCC Part 15 Class B, IEC 62109, IEC 62040, IEC 62477, SAA, cETL UL1741, and CSA C22.2, the HF4850U80-H meets a broad range of international and North American safety and EMC standards. The IP20 indoor enclosure with fan cooling measures 426 x 322 x 126mm and operates across a temperature range of -10°C to +55°C, well-suited for compact wall-mount installations in utility rooms, sheds, or off-grid cabins.
