从China供应商批发进口12v/24v Solar Charge Controller — FOB条款

This 12V/24V solar charge controller from Shenzhen Olys Company Limited uses PWM regulation and an MCC microcontroller to manage battery charging in off-grid photovoltaic systems. The unit automatically identifies 12V or 24V battery banks and applies a three-phase charging sequence: constant current, constant voltage, and float. Built-in temperature compensation adjusts the charging voltage based on ambient conditions, which helps maintain battery health across seasonal changes.

The controller provides comprehensive electronic protection against reverse polarity, short circuits, and overloads, safeguarding both the battery and connected loads. All boards are moisture-treated for outdoor use, a practical feature for installations in humid or exposed environments. Two LED indicators display system operating status, giving installers and operators a quick visual check without needing additional monitoring equipment. Typical PWM solar controllers in this voltage class handle panel inputs up to around 50V and support lead-acid battery types including AGM and gel, though buyers should confirm exact input limits with the supplier.

These controllers are commonly specified by solar installers, off-grid cabin builders, and small commercial system integrators working with 12V or 24V battery banks. Shenzhen Olys states it has focused on solar controller development and manufacture for 12 years and claims to serve over 300 new energy companies. Buyers should request the full datasheet, confirm supported battery chemistries, and verify the maximum solar panel input voltage before placing a bulk order.

Shenzhen Olys Company Limited is based in the Long Hua District of Shenzhen, Guangdong Province, China. The supplier profile lists it as a harbor-tier seller on the platform. The listing states the company has 12 years of experience in solar controller development and manufacture and claims to serve over 300 new energy companies, though buyers should request documentation to verify these figures.

The product description indicates the firm specialises in solar charge controllers and positions itself around core PWM and microcontroller technology. The response rate and average response time shown on the profile are currently at zero, so buyers should allow extra time for initial contact and may wish to request direct communication channels such as WeChat or email to confirm availability and lead times before committing to an order.
