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.

The RUiXU Lithium Batteries Kits provide centralized 48V lithium iron phosphate energy storage in 15kWh, 20kWh, 25kWh, and 30kWh configurations. Each configuration uses the RX-LFP48100 19-inch 3U server rack battery, with each battery providing 5.12kWh of nominal energy and 4.92kWh of usable energy.

The modular system supports up to 32 batteries in parallel and can scale from 5kWh to 160kWh without an external controller. DIP address settings allow selection of the RS485 baud rate and inverter protocol, while RS485 and CAN communication support the inverter protocols confirmed on the product page.

The batteries support rack-mounted, floor-mounted, wall-mounted, and stacked installation. The product page identifies the kits as CEC and SGIP and confirms UL1973 certification and completed UL9540A testing.
