Estimated shipping time

You can typically expect your items to arrive within 4–7 business days, depending on your location and product availability.

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.

This 3.6kW all-in-one off-grid inverter provides 120 Vac single-phase pure sine wave output for residential and commercial solar energy systems. It supports 48V lithium-ion, lead-acid, and user-defined battery configurations.

The inverter accepts up to 4,500W of solar input and supports solar, grid, and generator charging. Parallel operation allows up to six units to be combined, including supported split-phase and three-phase configurations.

Key Features

  • Hybrid Charging: Combines solar and grid charging with a maximum mixed charging current of 80A.
  • Time-Sharing Control: Allows charging and discharging to be scheduled for flexible energy management.
  • Parallel Operation: Supports up to six units for a combined rated output of 21.6kW.
  • Expandable Phase Configuration: More than two parallel units can form a split-phase output, while more than three can form a three-phase output.
  • MPPT Solar Charging: A single MPPT input supports up to 4,500W of PV input with 99% tracking efficiency.
  • Rapid Shutdown: Quickly de-energizes the solar PV system to help protect first responders.
  • Wireless Monitoring: Supports optional Wi-Fi or GPRS connectivity, with a Wi-Fi dongle included for app-based access and monitoring.
  • Pure Sine Wave Output: Supplies 120 Vac pure sine wave power.
