Compact 400W 12V Solar Power Kit for RV Off-Grid

The 400W Solar Panel Kit offers an ideal daily power output of 1.6KWH (under 4 hours of sunlight), making it perfectly suitable for RV, shed, cabin, home or other energy backup needs. It can provide enough power to run various AC 110V devices, such as TV, air conditioner, water heater, refrigerator, coffee maker, and microwave.

Featuring bifacial solar panels, this kit utilizes a transparent back of 12BB solar cells with a composite material design. The light transmittance of the back panel reaches up to 91.5%, and the conversion rate is an impressive 23%, resulting in a power generation of 858Wh per day under ideal conditions - 33% more than traditional solar panels.

The system is equipped with a 99% efficient MPPT (Maximum Power Point Tracking) technology controller, which maximizes the energy harvesting efficiency. This advanced configuration ensures a peak conversion efficiency of up to 98%, 40% higher than traditional PWM (Pulse-Width Modulation) charging controllers. The MPPT controller can maintain a stable charging current even on cloudy days, ensuring no sunlight is wasted.

The long-lasting lithium battery included in the kit is designed with a higher charge/discharge efficiency and more than 3,000 deep cycles, far exceeding the lifespan of lead-acid batteries. The built-in Battery Management System (BMS) further protects the lithium battery from overcharge, overdischarge, overheat, and short-circuit, ensuring reliable and safe operation.

The 1100W power inverter, with its advanced pure sine wave design, efficiently converts the 12V input to a 110V output with a 95% high conversion efficiency. This ensures the full utilization of the battery power without waste. Additionally, the inverter features a 1% ultra-low no-load loss, contributing to low self-consumption and saving battery power.

The package includes 4 x 100W bifacial solar panels, 1 x 40A MPPT controller, 1 x 1100W power inverter, 1 x 12V 100Ah lithium battery, 1 x Bluetooth Module 5.0, and other necessary accessories, providing a complete and versatile solar power solution.

Compared to the Solar Generator 1000 Kit, which has a maximum daily generation of 800WH/DAY and 1024WH of energy storage, the 400W Solar Panel Kit offers a higher maximum daily generation of 1600WH/DAY and 1280WH of energy storage. On the other hand, the Solar Generator 2000 Kit, with a maximum daily generation of 1600WH/DAY and 1920WH of energy storage, provides a similar level of power output to the 400W Solar Panel Kit.

The 400W Solar Panel Kit is a new product with limited-time promotional pricing, making it the lowest-priced offering of the year. It is part of a range of solar power solutions, including the 1200W Solar Tracker, 100W-800W Solar Panel Kits, 10KWH-20KWH Solar Power Systems, and various other solar kits and accessories, catering to diverse energy needs.
