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 split-phase hybrid inverter combines solar, battery, utility-grid, and generator power management in one unit for cabins, accessory dwelling units, tiny homes, residential properties, agricultural applications, and off-grid or grid-connected systems. It supports grid-tie, off-grid, and hybrid operating modes with pure sine-wave output.

For clarity, the unit accepts up to 12,000W of PV input and provides 10,000W of rated continuous AC output. It is offered in one configuration only, with no selectable product variants. Up to six identical units can be connected in parallel for expanded system capacity.

Key Features

  • Split-Phase Output: Supports 120/240V split-phase and 120/208V split-phase configurations.
  • Multiple Operating Modes: Supports grid-tie, off-grid, and hybrid operation.
  • Flexible Power Sources: Accepts solar PV, battery, utility-grid, and generator inputs.
  • AC Coupling: Built-in AC-coupled functionality supports system integration.
  • Parallel Expansion: Supports parallel operation of up to six identical units.
  • Pure Sine-Wave Output: Produces pure sine-wave AC power with 91% DC-to-AC efficiency.
  • Wireless Monitoring: Built-in Wi-Fi supports real-time monitoring through a mobile application.
  • Battery Communication: RS485 connectivity supports battery-management-system integration.
  • External Energy Monitoring: Uses an external CT sensor to support 100% self-consumption control.
  • Integrated Breakers: Includes an integrated 300A DC breaker and 60A AC breaker.
