Features: 1.Applicable to Various Scenarios: 100W solar panel is compatible with grid connected and off grid inverters for indoor power supply or outdoor use. Include your RV, boat and other outdoor equipment. 2.Half Cut Cell Technology: Solar panels use half cut cell technology, compared with standard modules, current is reduced by half, resistance loss is reduced, improve performance efficiency. 3.High Conversion Rate: Solar panel has the highest conversion rate of 21.9 percent . Increasing the receiving surface of the battery, the light band reduces the coverage area by 22 percent . It can charge 12V batteries or 24V batteries by wiring several solar panels in series. 4.Durable Frame: The waterproof and durable ABS frame protects the solar panels and is suitable for outdoor use in extreme weather, enabling the panel to last for decades. 5.Battery Protection: The controller protects the battery from overcharge or overdischarge by controlling the overvoltage current. Overcharging or discharging a battery will shorten its life. Specification: Item Type: Solar panel Power: 100W Controller: Voltage: 12V/24V Current: 30A Fitment: Suitable for: RV, campers
