How does a solar controller work at night?

At night, the controller stops charging and manages battery discharge to loads according to settings, preventing the battery from being over-discharged.

AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company and a trade company located in Zhongshan, with associated companies in manufacturing. It reports CE and RoHS certifications, customization from designs and samples, ODM services, and new product development during the past year. Production resources include three production lines and several listed machines, but the supplier does not continuously reconcile production quantities for each batch. Service procedures exist for supplier assessment, corrective actions, and complaint handling, yet no written records were provided. Overseas service infrastructure is limited: no overseas warehouse, showroom, agents, or branches, and no overseas service countries were reported. Financial records are referenced for 2022–2024, but no financial performance details are provided. No available SDK, no factory environmental impact assessment report, and no OEM service for popular brands were reported.

CertificationsThe supplier reports CE and RoHS certifications. These are explicit product or compliance certifications and provide positive evidence for this field.

After-Sales capabilityThe supplier has procedures for complaint handling, corrective and preventive actions, and service-capability assessment, but no written records are available. It has no overseas warehouse, showroom, agents, or branches, and reports service availability in zero overseas countries, limiting demonstrated after-sales coverage.

R&D capabilityThe supplier reports new products during the past year and provides ODM services, demonstrating some product-development capability. However, it explicitly reports no available SDK, so the evidence does not support a fully strong innovation capability across the requested scope.

Production capacityThe supplier lists multiple production-related facilities or equipment and reports three production lines. However, it does not continuously reconcile quantities for each batch or bulk production, which is an explicit production-control deficiency.

Customization capabilityThe supplier explicitly supports customization from designs and samples and provides ODM services. These capabilities directly demonstrate design-based and sample-based customization.

Product Q&A

Q:What is a solar controller?

A solar controller manages electrical energy transmission between solar panels and batteries, preventing overcharging or over-discharging to extend battery life and optimize system efficiency.

Q:What is the role of a solar controller?

It performs charging management, discharge protection, load control, and system monitoring to ensure safe and efficient operation of the solar energy system.

Q:What is the difference between a PWM controller and an MPPT controller?

PWM controllers reduce voltage directly with lower efficiency, suitable for small systems. MPPT controllers maximize output power by adjusting the operating point, offering higher efficiency for high-power or low-temperature systems.

Q:What types of batteries can a solar controller be used with?

Most controllers support Lead-acid (sealed/open), Lithium (LFP, ternary), and Gel batteries. Users must confirm compatibility with their specific battery type.

Q:Does a solar controller have overload protection?

Yes, most solar controllers feature overload protection that automatically cuts off output when load current exceeds the rated value to protect the system.
