DEFU DC 12V 2KW Gasoline Generators

DEFU DC 12V 2KW Gasoline Generator delivers robust off-grid power for demanding applications. This compact unit generates stable 12V DC output at 75A current, making it ideal for charging automotive/marine batteries, powering RV systems, and supporting renewable energy installations. Its high-efficiency gasoline engine operates at 4,200 RPM with remarkably low noise (50dB), ensuring reliable performance in remote locations while minimizing disturbance.

Engineered for durability , the generator features rugged construction that withstands harsh environments. Safety is prioritized through integrated overload protection and automatic voltage regulation (stabilized between 44.8V-58V). Critical safety protocols require horizontal installation to prevent carburetor leaks, and strict ventilation is mandatory - exhaust temperatures exceed 300°C, creating fire hazards in enclosed spaces. Operators must maintain 1m clearance from flammables and install 100A fuses on all output lines to prevent short-circuit fires.

Operational versatility extends to multiple start methods (electric/pull-start/remote control) and customizable voltage options (24V/48V/72V available). The 7-8L fuel tank uses ≥92-octane unleaded gasoline, with a fuel-efficient design that maximizes runtime. Maintenance follows strict intervals: initial oil change at 30 operating hours, routine servicing every 50 hours (oil replacement, air filter cleaning), and comprehensive decarbonization every 200 hours. For long-term storage, complete fuel drainage and cylinder oiling are essential to prevent corrosion.

Smart automation enables self-start functionality when voltage drops to 21-23V, while automatic shutdown activates at 28.5V with sustained low current (5A). This makes it particularly suitable for integration with DC air conditioning systems and off-grid power banks. Commercial orders start from 10 units with 15-20 day production lead times, backed by CE/EMC/MSDS certifications.
