Import Dual Load & Timeframe Solar Controller — Buy in Bulk from Supplier in China

The Dual load & timeframe solar controller (model SR-2LT series) is a charge and discharge regulator designed for off-grid solar systems with two independent output circuits and programmable lighting schedules. It supports rated charging and discharging currents of 5A, 10A, 15A, or 20A, and operates at 12V, 24V, or auto-switching 12V/24V. The controller automatically detects nightfall to maintain precise lighting duration without external timers.

It accepts standard lead-acid batteries and is compatible with common 12V or 24V solar panel arrays. The dual time period function allows separate on/off settings for two distinct lighting zones, such as pathway and area lighting, each with independent duration control. No load losses are minimal, typically under 10mA, to preserve battery life during extended idle periods. This design is typical for small to medium off-grid installations in rural or remote locations where grid access is limited.

Buyers commonly use this controller in street lighting systems, agricultural irrigation pumps, and remote telecom repeaters. It is sourced by distributors in Southeast Asia, Africa, and Latin America who require reliable, low-maintenance solar regulation. Trade terms typically include FOB Shenzhen or CIF port, with packaging in standard cartons of 10 to 20 units. MOQ and lead time must be confirmed directly with the supplier.

Shenzhen Shuori New Energy Technology Co., Ltd. is a manufacturer based in Baoan District, Shenzhen, with a registered industrial address at 9/F, Building B Jianyu 2nd Industrial Park. The supplier is classified as imported and verified by harbor trust indicators, suggesting active export compliance. The listing does not state years in business, certifications, or client names, and no revenue or employee figures are disclosed.

The company specializes in solar charge controllers and related power management devices. Its production focus appears to be on mid-volume models for international distributors, with no indication of retail branding or direct consumer sales. The absence of response rate or average reply time suggests limited buyer communication infrastructure, requiring direct inquiry for technical confirmation.
