Description
The SRNE HESP48180UH3 is an 18kW 48V three-phase hybrid solar storage inverter designed for large residential and light commercial applications requiring high-power off-grid capability, fast battery charging, and scalable parallel system design.
Key Features
- 3 Independent MPPT Channels Three separate MPPT inputs accept up to 36,000W of PV array power at 600V open-circuit voltage with 40A per channel, delivering up to 1.6 times the rated inverter power.
- Ultra-Fast 350A Charging Maximum hybrid, grid, and generator charging current of 350A enables rapid battery replenishment, with BMS self-adaption for optimized lithium battery charge control.
- Parallel Scalability to 162kW Supports up to 9 units in parallel for single-phase, split-phase, or three-phase output, enabling seamless scaling from residential to commercial and industrial system sizes.
- AC Coupling & Smart Load Function Built-in AC coupling compatibility and smart load output control allow integration with existing grid-tied systems and intelligent load management without additional hardware.
- Time-Slot Peak-Valley Optimization Programmable time-slot charging and discharging schedules maximize savings by aligning energy use with off-peak electricity pricing periods.
The HESP48180UH3 delivers 18,000W rated AC output at 120/208V three-phase with a maximum off-grid peak power of 36,000VA and a max efficiency of 97.5%. The unit supports two independent 48V battery inputs over a 40–60Vdc voltage range, with a maximum discharging current of 350A and self-adaption to lithium BMS communication via RS485 or CAN.
Certified to UL 1741-2021 (UL1741SB), CSA C22.2 No. 107.1-16, IEEE 1547-2018, UL 1699B, CEC, SGIP, and CSIP, the HESP48180UH3 meets all major North American grid interconnection and safety standards. Communication interfaces include RS485, CAN, USB, and dry contact, with optional Wi-Fi and 4G module support for remote monitoring.
Built to IP65 in a wall-mount enclosure with heat sink and intelligent air cooling, the unit operates from -25°C to +60°C with derating above 45°C. A dedicated generator input port, dual battery inputs, 200A bypass overload capability, and a 5-year standard warranty round out the feature set.
