What is your Return Policy?

At Northgrid Supply, we want every customer to shop with confidence. If something doesn’t go as planned, we’ve made returns and refunds simple and fair. Here’s how it works:

1. Return Window

You can request a return within 30 days of receiving your order. Unfortunately, we’re unable to accept returns after that time frame.

2. Who Pays for Return Shipping?

  • If your item arrives damaged, defective, or incorrect, we’ll cover the return shipping cost.
  • If you’re returning an item because you changed your mind, you’ll be responsible for return shipping fees.

3. Damaged or Defective Items

Received something broken or not working properly? Contact us within 30 days. We’ll provide a prepaid return label and once the item is returned and inspected, we’ll issue either a full refund or a replacement—including any original shipping costs.

4. Changed Your Mind?

If you no longer want the item, you can return it within 30 days—as long as it's unused, in its original packaging, and in resellable condition. You’ll need to handle the return shipping, and once we receive and inspect it, we’ll refund the product cost (excluding shipping).

5. Refund Processing

Once we receive and approve your return, we’ll send a confirmation email and issue a refund to your original payment method within 7 business days. Please allow additional time for banks or credit card companies to process and reflect the refund.

If it’s been over 10 business days since your refund was approved and you still don’t see it, contact us at support@northgridsupply.com and we’ll look into it immediately.

6. Restocking Fees

In some cases, a restocking fee may apply depending on the item and return reason. If applicable, we’ll clearly communicate this during your return request process.

The 520W Slim Kit is a compact solar charging package built around four 130W slim monocrystalline solar panels and a 40A MPPT solar charge controller. The included panel platform is designed for off-grid and mobile installations, including RVs, cabins, and boats, with a narrow panel profile that supports flexible mounting configurations.

The system includes the solar array, MPPT charging, panel-to-controller and controller-to-battery cabling, a Y-branch parallel adapter, mounting hardware, and an inline solar fuse. The charge controller supports automatic 12V/24V detection, multiple lead-acid and lithium battery chemistries, built-in Bluetooth monitoring, and configurable charging parameters.

Key Features

  • 520W Solar Charging Kit: Includes four 130W slim solar panels as the kit's solar array.
  • N-Type TOPCon Solar Cells: The included 130W slim panels use N-Type TOPCon multi-busbar cell technology designed to improve light trapping, reduce series resistance, and enhance current collection.
  • 25.3% Maximum Cell Efficiency: The solar panel specification lists maximum cell efficiency of 25.3%.
  • Slim Panel Format: Each panel measures 65.0 × 15.8 × 1.2 in and weighs 15.4 lb.
  • Low-Light Performance: The panels are designed to maintain energy production during cloudy conditions and during mornings and evenings.
  • Durable Panel Construction: High-transmission anti-reflective coated tempered glass is paired with a lightweight, corrosion-resistant anodized aluminum-alloy frame.
  • Series or Parallel Connections: Plug-and-play solar connectors support both series and parallel panel configurations.
  • Flexible Mounting Options: Pre-drilled mounting holes support ground mounts, Z-brackets, pole mounts, and tilt systems.
  • Off-Grid and Mobile Applications: The panel specification identifies RVs, cabins, and boats among suitable off-grid and mobile applications.
  • Harsh-Environment Resistance: The panel design is specified for environments involving salt, ammonia, sand, high temperatures, and high humidity.
  • Mechanical Load Strength: Panel mechanical strength is certified for up to 5400 Pa positive load and 2400 Pa negative load.
  • 40A MPPT Solar Charging: The included controller uses true MPPT technology with tracking efficiency above 99.5% and charge conversion efficiency up to 98%.
  • Automatic 12V/24V Detection: The controller automatically supports 12V and 24V nominal battery systems.
  • Multiple Battery Chemistry Support: Supported battery presets include GEL, AGM, WET, CRYSTAL, CALCIUM, LiFePO₄/LFP, LTO, and LCO.
  • Multi-Peak MPPT Detection: The controller supports multi-peak detection for optimized tracking under shaded conditions.
  • Built-In Bluetooth: The controller includes a built-in Bluetooth module for monitoring and control.
  • LCD System Monitoring: A large LCD provides real-time solar input, battery status, and system-configuration information, supported by LED and transparent-window indicators.
  • Custom Charging Parameters: Charging parameters can be customized, and charging data can be stored by the controller.
  • Battery Recovery Function: The controller includes a deep-discharge battery recovery/restart function.
  • Electronic Protection: Controller protections include over-voltage protection, reverse-discharge protection, common-negative grounding, conformal-coated circuitry, and built-in circuit and safety protection.
  • Optional Temperature Sensor Support: The controller supports an optional external battery-temperature sensor.
