Product Detail

Shanghai Mac Corporation is a leading Solar Controller manufacturer and supplier.

A solar charge controller is an essential device used to manage and regulate power between solar panels and batteries. It is widely applied in off-grid solar systems, home energy storage, solar street lights, RVs, boats, communication stations and outdoor power systems.

The controller regulates charging voltage and current, improves solar energy utilization, and prevents battery overcharging or excessive discharge. With multiple protection functions, it helps extend battery life and ensures safe, stable and efficient operation of the entire solar power system.

Main Materials: Solar charge controllers adopt aluminum or ABS housing, PCB, semiconductors, capacitors, heat sinks, terminals, display and communication parts.

Main Structure: It includes power conversion, charge control, protection, heat dissipation, display and communication modules. It regulates solar power, controls battery charging and provides multi‑protections like over‑voltage, short‑circuit and reverse‑polarity.

Controller Types: There are PWM and MPPT controllers. PWM is simple for small cost‑saving systems; MPPT boosts power harvest for medium‑large or high‑efficiency projects.

1. Intelligent Charging Management Auto‑adjusts charging voltage and current based on battery status. It raises charging efficiency and prolongs battery life.

2. High‑Efficiency MPPT Technology It tracks solar panels’ maximum power point for better solar energy utilization. More power is obtained even under variable sunlight.

3. Multiple Safety Protections It supports over‑charge, over‑discharge, over‑voltage, over‑current, short‑circuit, reverse‑polarity and overheat protection. It lowers failure risks and enhances system safety.

4.Compatible with lead‑acid, AGM, GEL and lithium batteries subject to models. It brings flexibility for solar system design and upgrade.

Residential Off‑Grid Solar Systems Solar charge controllers manage power from PV panels to battery banks for home off‑grid systems. 24V/48V MPPT (40A‑100A) optimize solar utilization and ensure stable battery charging.

Solar Street Lighting Controllers auto‑handle daytime charging and night power supply for street & garden lights. 12V/24V, 10A‑30A PWM/MPPT are widely adopted for standalone lighting.

Standard Packaging:

Each solar charge controller is packed in a protective plastic bag or foam insert, then placed in an individual carton box with the user manual and necessary accessories. Multiple units are packed in a strong export carton with protective cushioning to prevent impact, moisture, and damage during transportation. Pallet packing is available for bulk orders upon request.

Shipping:

Solar charge controllers can be shipped by express courier, air freight, sea freight, or rail transportation, depending on order quantity and delivery requirements. Small orders and samples are usually shipped by DHL, FedEx, or UPS, while bulk orders are suitable for air or sea freight. Export cartons and optional pallet packing ensure safe transportation and reduce the risk of damage during transit.

Lead Time:

Standard orders: 20‑30 working days

Customized oders: 30‑50 working‑days

Q: What is the difference between MPPT and PWM solar charge controllers?

A: MPPT controllers provide higher charging efficiency and are better suited for medium-to-large solar systems. PWM controllers are simpler and more economical, making them suitable for smaller, cost-sensitive applications.

Q: How do I choose the correct solar charge controller size?

A: The controller should be selected according to the solar panel voltage and power, battery system voltage, and required charging current. Common options range from 10A to 100A for 12V, 24V and 48V systems.

Q: What battery types are compatible with the controller?

A: Depending on the model, our controllers can support lead-acid, AGM, GEL, lithium-ion and LiFePO4 batteries. Charging parameters can be configured for different battery types.

Q: What protection functions are available?

A: Typical protection functions include overcharge, over-discharge, overvoltage, overcurrent, short-circuit, reverse-polarity and over-temperature protection to ensure reliable system operation.

Q: Can the solar controller support remote monitoring?

A: Yes. Selected models can be equipped with RS485, Bluetooth or Wi-Fi communication, allowing users to monitor operating data and manage the solar charging system more conveniently.
