从China供应商批发进口50w Solar Power System — FOB条款

The 50W Solar Power System from Guangzhou Sunnyksy Solar Co., Ltd. comprises a 50W polycrystalline solar panel, a 12V 10A solar charge controller, a 300W solar inverter, and a 12V 38Ah lead-acid battery. This configuration is designed for 12V DC and modified AC output scenarios where grid access is limited or absent. The polycrystalline panel technology offers a balance of cost and performance for entry-level solar deployment. The integrated charge controller provides overcharge and deep-discharge protection for the battery bank. The 300W inverter capacity allows simultaneous running of multiple small loads within its surge tolerance.

The 38Ah lead-acid battery stores approximately 456Wh of nominal energy, though usable depth of discharge in standard practice is 50 percent to preserve cycle life. Typical daily yield from a 50W panel in moderate insolation conditions ranges from 150Wh to 250Wh, depending on latitude, tilt angle, and seasonal variation. The charge controller's 10A rating accommodates panel expansion up to roughly 120W at 12V, giving buyers a modest upgrade path. Standard industry practice for such kits includes temperature-compensated charging, though buyers should verify whether this unit includes that feature. The sealed lead-acid battery requires no electrolyte topping but still benefits from ventilated installation.

Primary applications include remote lighting, small appliance power, telecommunications backup, agricultural monitoring equipment, and off-grid cabins. Buyers typically include rural electrification projects, disaster relief organisations, small-scale installers, and remote facility operators. Trade terms mentioned include FOB and CIF shipping options, with payment by L/C or T/T. The supplier indicates flexible MOQ, though exact minimum quantities are not specified and should be confirmed directly with Guangzhou Sunnyksy Solar Co., Ltd. before order placement.

Guangzhou Sunnyksy Solar Co., Ltd. is located at No.6 Building, Yiheng Road, Xipengling, Guangzhou, Guangdong Province, 510000, China. The company holds a 'harbor' trust tier, which indicates a baseline verification level on the platform. The response rate is recorded at 0.00 percent with an average response time of 0 hours, suggesting limited or no response history through the platform's messaging system. Buyers should note that direct communication channels may yield better engagement than platform-only messaging.

The supplier profile does not disclose manufacturing floor space, employee count, annual revenue, client roster, or certification documentation. No ISO, CE, or IEC accreditation details are provided in the source material. The listing emphasises export-oriented supply with flexible order quantities and standard international payment instruments. Buyers are advised to request factory audit reports, test certificates for the charge controller and inverter, and sample performance data before committing to volume orders. The address in Guangzhou places the supplier within the Pearl River Delta electronics manufacturing cluster, a region with extensive solar component supply chain access.
