What is your Return Policy?

At Miles Off Grid, 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@milesoffgrid.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.

Product Description

Overview

The Tigo TS4‑A‑O is a module‑level power electronics (MLPE) device that provides optimization, monitoring, and NEC‑compliant rapid shutdown for PV systems. Supporting modules up to 725W and 22A (Isc), it improves energy harvest, system visibility, and safety across residential, commercial, and utility‑scale installations.

Designed for selective deployment, the TS4‑A‑O allows installers to optimize only the modules that need it—such as shaded areas, mixed orientations, or mismatch conditions—reducing hardware costs while maintaining system performance.

Note:

  • Tigo TAP is required for rapid shutdown communication.

  • Tigo CCA (Cloud Connect Advanced) is required for module‑level monitoring.

Key Features

  • High module compatibility — Supports 700–725W modules and high‑current designs

  • Predictive IV (PIV) optimization — Maximizes real‑world energy harvest

  • Selective deployment — Use optimizers only where needed

  • NEC 2014/2017/2020 rapid shutdown compliance

  • Module‑level monitoring with TAP + CCA

  • Instant optimization — No special setup required

  • Shade and mismatch tolerance — Maintains output under uneven conditions

  • Wireless communication for simple commissioning and system visibility

Why Choose the TS4‑A‑O

The TS4‑A‑O provides flexible optimization for modern PV systems, enabling unequal string lengths, multiple orientations, and partial shading without requiring full‑array deployment. Combined with Tigo’s real‑time monitoring and plug‑and‑play rapid shutdown, it enhances safety, performance, and long‑term system reliability.

Suitable for residential rooftops, commercial arrays, and utility‑scale projects using next‑generation high‑power modules.
