Secure Your Off-Grid Power – Anchor Your Solar and Battery Trailers with Confidence
Off-grid solar and battery trailers are revolutionising how we power remote locations, temporary worksites, outdoor events, and rural installations. Whether you’re running a construction project, supporting a festival, or powering a tiny home or transportable building, these trailers bring energy independence right where it’s needed. But with mobility comes vulnerability—especially when exposed to the elements.
Solar panels mounted on trailers often tilt upwards or extend sideways to maximise sunlight exposure. While great for power generation, this dramatically increases the wind sail area, making your setup more prone to shifting, wobbling, or even tipping during strong gusts or sudden storms. Even stabiliser legs alone aren’t always enough, particularly on soft or uneven ground.
That’s where GroundGrabba’s heavy-duty, drill-driven ground anchors come in. Designed to twist deep into the ground using a cordless drill or impact wrench, GroundGrabbas provide high-torque anchoring strength in conditions ranging from sand and clay to loam and semi-compacted soil. It’s fast, reliable, and repeatable.
Whether you’re securing a mobile solar and battery system, a modular home, or a relocatable office, GroundGrabbas offer a field-proven solution to:
- Anchor trailer chassis or skid base frames directly to the ground
- Brace stabiliser legs or support jacks from movement
- Secure deployable solar arrays and tilt frames with guy ropes or brackets
- Prevent lifting and shifting in cyclone-prone or high-wind environments
- Hold mobile infrastructure safely in place for both safety and theft deterrence
We’ve also seen these anchors used to stabilise hybrid energy units, mining trailers, water pump trailers, and portable communications towers. Increasingly, they’re being adopted in the off-grid tiny home and modular building industries, where transportable dwellings need to be secure, stable, and compliant—without the need for permanent footings.
What makes GroundGrabba unique is its ability to drill below the unstable topsoil layer, gripping into firmer material beneath. In contrast to hammer-in pegs or star pickets, which often bend or slip out, GroundGrabbas can hold up to 7x more under tension in soft to medium soils.
Our range of interchangeable adaptors lets you tailor your anchoring system to your exact application:
- Multi L Brackets connect trailer chassis or frame corners to the anchor head
- ClosedHooks are ideal for strapping over trailer feet or guy rope loops
- Hook Washers ensure secure mounting through timber or baseplates, preventing hex collars from pulling through oversized holes
For general off-grid trailer applications in soft to medium ground, the GroundGrabba Pro I and Pro II models offer ample depth and grip. The Pro II, at 615mm, is preferred for looser soil. If you’re installing in hard clay, compacted road base, or want extra peace of mind in cyclonic zones, our Commercial Pro I or Commercial Pro II are engineered with a thicker shaft for added strength.
We also recommend GroundGrabbas for use alongside:
- Tiny homes on wheels
- Relocatable classrooms or site offices
- Transportable buildings
- Modular dwellings
- Pop-up medical or telecom trailers
All GroundGrabbas install in seconds with a ½" cordless drill—no more digging, sledgehammers, or broken pegs. Once installed, they’re easily removed and reusable, making them ideal for sites where mobility and fast setup are key.
If you’re managing a remote installation or responsible for workplace safety, don’t wait for disaster to strike. Proper anchoring of your solar or battery trailer is essential to protect your investment—and those working or living nearby.
