Important note: on grid tie inverter, it MUST PLUG INTO YOUR HOME GRID, it CAN’T power your device directly. for 12v solar system, the best working voltage(MPPT) is about 18-24v. sometime buyer said it can’t work when it is 13v, the buyer should use it as an off grid. it is wrong using way.
Multi-protection function: Over Current Protection/Over Temperature Protection/Reverse Polarity Protection/Island Protection
Features: Stackable/MPPT-Maximum Power Point Tracking/Automatic Sensing Function Solar Luminosity and restart automatic every morning
Safety: DC and AC all have fuse to protect the people + power switch +we do the speical for the aluminum shell, it is insulation
Cooling method: fan-cooled+aluminum shell, more better cooling function, smart and light (1.8 kg), easy to carry and handle.
