Keep Critical Loads Running When the Grid Goes Down

The Enphase IQ Load Controller lets you prioritize essential appliances during a grid outage, shedding non-critical loads to prolong battery life in your off-grid or backup system. It controls up to two 36A dedicated loads or two 32A solar branch circuits, and can shed excess IQ6, IQ7, M215, or M250 production to maintain your solar-to-storage ratio. With a weatherproof NEMA 4X enclosure and DIN rail mounting, this field-tested controller is built-to-survive indoor or outdoor installations. Configure via the Enphase Installer App and manage loads directly from the Enphase App. Backed by a 5-year warranty.

Keep Critical Loads Running Through Extended Outages

Keep Critical Loads Running Through Extended Outages

A four-day blackout should not mean a freezer full of ruined meat and nights without heat. The IQ Load Controller automatically sheds non-essential circuits when battery reserves drop, so your refrigerator, well pump, and lights stay powered longer. Unlike grid-tied systems that go dark the moment the utility fails, this controller works with your off-grid architecture to make intelligent decisions about where every watt goes. At Off Grid Vault, we vet every component for real compatibility — this controller integrates directly with the IQ System Controller, no guesswork required. You get load shedding that actually works when it matters.

Manage Two Circuits With One Controller

Manage Two Circuits With One Controller

One IQ Load Controller handles up to two 36A resistive loads or two 32A solar branch circuits — giving you granular control over your energy allocation without adding complexity. Need to shed an excess solar branch to maintain your solar-to-storage ratio while off-grid? This controller handles IQ6, IQ7, M215, or M250 circuits up to 32A each. Running at 240VAC? You get two circuits. Running at 120VAC? That doubles to four controlled loads. The DIN rail design keeps your panel clean and makes future servicing straightforward — no specialized tools, no proprietary enclosures.

Configure and Control From Your Phone

Three load control modes give you flexibility, and manual override through the Enphase Installer App means you adjust priorities on demand — no walking to the breaker panel. The NEMA 4X enclosure handles indoor or outdoor installations without additional weatherproofing, and configuration takes minutes through the app. This is off-grid proven hardware backed by a 5-year manufacturer warranty. When you add it to your system through Off Grid Vault, you also get our free system design consultation to confirm it integrates correctly with your existing IQ architecture.

“Installed this with my IQ System Controller on the cabin setup. During a three-day outage last winter, it automatically shed my water heater and shop circuits while keeping the fridge, well pump, and lights running. Battery bank lasted the full three days without dropping below 40% state of charge. Setup through the Enphase app took about ten minutes. Exactly what I needed.”

Frequently Asked Questions

At $376, the IQ Load Controller pays for itself the first time it prevents a freezer full of food from spoiling during an extended outage. By shedding non-essential loads automatically, you get more usable hours from your existing battery bank — no additional batteries required. Think of it as extracting more value from the storage you already paid for rather than buying more capacity.
Off Grid Vault is an authorized dealer for Enphase and other major brands including Sol-Ark, EG4, Renon Power, Schneider Electric, and Victron Energy. That means your 5-year manufacturer warranty is fully backed — warranty claims go through us, not through a ticket queue with a third-party seller. You get human accountability from people who understand off-grid systems.
Yes. The IQ Load Controller is designed specifically as an add-on for the IQ System Controller's load control feature. It does not operate as a standalone device. If you are running an Enphase IQ system with battery storage and want automated load shedding, this controller integrates directly. Not sure if your current setup supports it? Contact us for a free system design consultation — we will confirm compatibility before you buy.
You can add the IQ Load Controller to an existing Enphase IQ system at any time. Installation involves mounting the DIN rail unit and connecting it to your load circuits and the IQ System Controller. Configuration is handled through the Enphase Installer App. If your system already includes the IQ System Controller, the integration is straightforward. Our free consultation can walk you through the exact installation sequence for your setup.
Yes. The IQ Load Controller uses a NEMA 4X enclosure, which provides protection against windblown dust, rain, sleet, and external ice formation. It is designed for both indoor and outdoor installations without requiring an additional weatherproof box. This is field-tested hardware built for real environmental conditions, not controlled indoor environments. The 5-year warranty covers manufacturing defects regardless of installation location.
One IQ Load Controller manages up to two circuits. At 240VAC, that is two 36A resistive loads or two 3HP inductive loads. At 120VAC, it doubles to four controlled loads. You can also use it to shed up to two solar branch circuits (IQ6, IQ7, M215, or M250) at 32A each to maintain your solar-to-storage ratio. If your system requires more than two circuits, multiple controllers can be installed.
