Renogy 2PCS Solar Panel Kit 550 Watts 12/24 Volts Monocrystalline PV Power Charger On/Off-Grid Supplies & Deep Cycle AGM Battery 12 Volt 200Ah, 3% Self-Discharge Rate, 2000A Max Discharge Current

• Product 1: [High-Powered Module] The 2×550W solar panels are engineered with high-efficiency PERC (Passivated Emitter and Rear Contact) cells, capturing more light to achieve 22.8% conversion efficiency. Resulting in higher performance than most conventional panels, Renogy's 550 watt panels provide more output per surface area. Product 1: [High Tolerance] Renogy's high-powered 550 watt solar panels are made with half-cell technology. This half-cut panel is more tolerant of shading on any part of the cell and performs excellently in low light situations due to the increased number of cells receiving more sunlight. Product 1: [Optimized Space and Installation] A great option for large-scale installations, each solar panel can produce up to 2750 Wh of electricity per day and requires fewer installations per panel on your rooftop. Product 1: [Reliable and Durable] Corrosion-resistant aluminum frame provides extended outdoor use that ensures the panel can last for decades. The IP68 rated junction box and solar connectors can withstand dirt, dust, debris, and water splashes. Product 2: Maintenance Free: Manufactured with thick absorbent Glass Mat (AGM) seperators and advanced valve regulated technology, Renogy deep cycle agm batteries save you from acid leakage and frequent maintenance. Product 2: Excellent Discharge Performance: Proprietary quinary alloy plates and specially treated plate grids enable low internal resistance and high discharge currents of up to 10 times the battery rated capacity. Product 2: Long Shelf Life: Made of high purity materials, Renogy deep cycle agm batteries reduce the monthly Self discharge Rate below 3% at 77℉ (25℃), which is 5 times lower than their flooded counterparts. Product 2: Wide Operation Temperature Range: Improved electrolyte Formula ensures stable battery capacity and outstanding discharge performance at low temperatures below 32℉ (0℃).
