Solar panels (flexible) each panel 100 watts, total 300 watts. Details: Panels: 1 new panel in the box, unused, 100 watts 2 used panels, 200 watts total, each panel 100 watts (had a protective sticker, removed, some glue residue remains on the panel, can be cleaned). The panels are working at full capacity. Maximum Power (Pmax) 100 W Open Circuit Voltage (Voc) 21.2 V Short Circuit Current (Isc) 6.25 A Maximum Power Voltage (Vmp) 17.7V Maximum Power Current (Imp) 5.68 A Maximum System Voltage 700 VDC Size 1050*540*3MM Inverter: Used power inverter, 12v, 1000 watts real power, supports up to 2000 watts (Pure Sine Wave - clean electricity like what we use). Charge Controller: Used MPPT solar charge controller, working at full capacity, excellent for extracting maximum power from panels. Model: Tracer4210A Voltage: 12/24V Current: 40A Max. PV Voltage: 100V Max. PV Input Power: 520W(12V), 1040W(24V) Wiring: Approximately 6 meters of wiring included, connected to a 12v system, original, sun-resistant, and high-amperage resistant. Spare Parts: Spare connector heads shown in the picture for connecting solar cells are included. **Important Note** There is a picture below, the last one, showing the inverter and charge controller during use (this is an old picture). Now, the inverter's front sticker has peeled off over time, and the charge controller's plastic has yellowed, and its screen has some black spots, but the data can still be read as shown in the last picture. The system is working and has no faults.
