12KW (12000W) Solar Hybrid Off-Grid Inverter 48V DC to 120/240V Split-Phase Pure Sine Wave, Low-Frequency with 2×80A MPPT Controllers

Overview: GS Series hybrid inverter for off-grid and backup power use. Low-frequency, transformer-based design with 48V DC input and split-phase AC output (110/120 Vac per leg, 120/240V total). Model information includes a transformer-rated 8KW continuous inverter core with 24kW peak capability, and is offered as a 12KW (12000W) hybrid solution. Output frequency can be set to 50 or 60 Hz via the LCD panel and AC output synchronizes in phase and frequency with the AC input for seamless transfers. Battery & charging compatibility: Supports multiple battery types including Lead-Acid, GEL and Lithium, and provides lithium battery communication. The unit works with utility mains or a generator to charge batteries or directly power loads. Automatic Generator Start (AGS) triggers when battery voltage is low or the utility is absent. Charging current is user-adjustable from the LCD screen. Integrated solar charging: Equipped with two MPPT solar charge controllers (2×80A). It can accept two 80A PV strings (Max 4500W) from three separate arrays, or be paralleled to accept 160A (Max 2×4500W) from a single large PV array. Maximum total charging current is 240A. The inverter also features Smart Remote Control and automatic fan-speed regulation that changes cooling based on ambient temperature. Operating modes & loads: Choose between AC-priority, DC-priority or Intelligent mode to suit system requirements. The GS Series handles common household electronics (TVs, computers, lights, fans) and is designed for heavier inductive loads such as refrigerators, air conditioners, motors, washing machines, pumps, compressors and laser printers. Robust low-frequency design & protections: Built with a pure copper low-frequency transformer, the inverter offers multi-layer protection against overload, short circuit, over-temperature, under-voltage and over-voltage. The transformer topology better copes with prolonged power spikes from inductive loads. Quality & certification: Manufactured under strict ISO9001-aligned quality controls (IOC, IPQC, FQC, OQC, QA covering raw material selection, production, packaging and shipment). The GS Series carries ETL certification to UL 1741 standards, ensuring regulatory compliance and reliable performance. Technology note: Advanced DSP digital control enables higher power-density integration and a more compact footprint while maintaining all-in-one inverter-plus-MPPT functionality to meet the needs of users in grid-off or remote locations.
