To ensure a great shopping experience, please strictly note the following 3 points: 1. BATTERY NOT INCLUDED! This off-grid solar system MUST be connected to a 12V battery(Lead-acid, Gel, LiFePO4, etc.) to work. The solar panel CANNOT power appliances or the inverter directly without a battery! 2. UNDERSTAND THE REAL POWER: The inverter in this kit has a Continuous Output of 750W(7000W is only the ultimate peak surge power for starting appliances). This starter kit(40W panel + 750W inverter) is perfect for: charging phones/tablets, LED lights, small fans, and routers. 3. SOLAR REALITY CHECK: The 40W solar panel is designed for battery maintenance and lightweight trickle charging. Solar efficiency depends entirely on sunlight. It will NOT produce effective current on cloudy/rainy days, at night, or through a glass window. Please place it outdoors under direct, unshaded sunlight. Key Features & Operational Layout: Photovoltaic Energy Modulation: Utilizes a solar collection panel engineered with a matrix-distributed dot surface configuration to optimize light refraction, delivering a consistent current output under standardized sunlight exposure. Intelligent Charge Regulation: Features an electronic charge controller capable of automatic system voltage identification, equipped with digital monitoring interfaces and secondary low-voltage USB power outputs for direct accessory operation. Stable Power Alternating Output: Incorporates a multi-protection power inverter designed to transition direct current (DC) into alternating current (AC), enabling localized power delivery for compatible minor consumer electronics. Integrated Safety & Electrical Shielding: Built with continuous diagnostic circuitry delivering alternative safeguards against system overload, short-circuit anomalies, over-voltage spikes, under-voltage drops, and localized thermal elevation. Technical Specifications: Product Type: Off-Grid Photovoltaic Power Generation & Inverter Starter Kit Solar Panel Power Rating: 40W Peak (Output Matrix: M-C-4 18V / Structural Size: 540 mm x 280 mm) Charge Controller Specification: Automatic 12V/24V Voltage Detection Protocol (Rated Current: 100A with LCD Status Display Window) Inverter Conversion Performance: 750W Continuous Output Rating (DC 12V Input to AC 110V or 220V Adaptive Output) Ingress Protection Level: IP65 Water-Resistant Solar Panel Construction Application Scope: Optimized for off-grid battery trickle-charging, localized auxiliary power maintenance, vehicle-mounted storage batteries, low-wattage lighting, and field-work data terminals. Systematic Wiring & Installation Sequence To establish proper electrical logic and ensure systemic component stabilization, the installation sequence must be executed according to precise industrial technical guidelines: Primary Battery Coupling: The localized 12V external storage battery must be wired to the designated terminal blocks of the charge controller first. This initial step permits the integrated microprocessor to correctly evaluate and configure the internal system voltage parameters before any current input is generated. Secondary Photovoltaic Connection: Following battery initialization, the output cables of the solar panel array may be interconnected with the dedicated photovoltaic input terminals on the controller framework. Tertiary Inverter Integration: The power inverter module must be wired directly to the primary structural terminals of the external storage battery. The inverter assembly must not be integrated into the auxiliary load terminals of the charge controller to prevent current saturation anomalies. Decommissioning Protocol: When dismantling the electrical circuit, the exact inverse progression must be maintained (disconnecting the solar panel array prior to terminal detachment of the central battery source).
