Purchased for around 100,000 yen. I am selling this because I no longer need it for work. (The main unit has been used only a few times and is in relatively good condition. Some of the wiring without connectors is from when I used a similar inverter in the past, so it shows some wear.) The main unit, wiring, and battery connection hardware are all included, so you can start using it right away. It will also be shipped in the blue container box shown in the photos. I am not a professional, so I cannot provide advice on usage or installation. Please understand. High-output 2500W DC-AC inverter with 4 output outlets. - Model Name: Cellstar 2500W - Output: 2500W - Input Voltage: 12V - Number of Output Outlets: 4 No returns. Thank you for viewing.
