What's in an Off-Grid Solar System?

We assemble, wire, and test all the parts necessary to run your off-grid system right in our warehouse. Our designers are pros at building flexible systems that can be expanded if your energy needs change down the road.

Your Batteries, Your Power Utility.

Batteries make off-grid solar possible. Without access to the utility grid, you need a reliable way to store the energy you generate for later use.

Your battery bank keeps your appliances running — even at night or during winter, when the sun isn’t shining. It’s critical to build a battery bank that can store enough energy to get you through off-peak production periods. Our available battery banks come packaged with the capacity to get the job done.

There are three battery types commonly used for off-grid solar:

  • Flooded Lead Acid
  • Sealed Lead Acid (AGM or Gel)
  • Lithium

Solar Panels

Simply put, panels absorb sunlight and convert it into electricity.

We hand-select panels that are compatible with the batteries, power centers and other components packaged with your off-grid system. We double-check the math on voltage, amperage and string size to make sure you don’t damage your components.

Where possible, we feature US-made panels with warranties that eclipse the industry standard. Your off-grid system runs 24/7, so your panels should be as reliable as possible. We’ve got you covered.

Power Center

A power center is a pre-wired off-grid inverter system with everything you need to get started: inverter, charge controller, remote control, and circuit breakers.

We assemble power centers in-house and test them on our workbench to make sure everything works the first time and every time. Once the power center passes our internal tests, we label the final connection points for you to make installation as easy as possible.


Most of our power centers have extra components for monitoring and protection. Accessories like battery monitors and surge suppressors help you keep an eye on your system to ensure it runs smoothly.

Racking System - Roof or Ground?

Once you have the components, you’ll need to mount them in place.

We offer several racking solutions to mount your system. Ground mounts can be aligned at the perfect angle to get the most output from your panels. Roof mounts are more cost-effective because they take advantage of your existing roof structure.

Roof Mount

Roof-mounted systems need flashings or clamps to attach to your roof top. We do not include these in our packages because the product you choose depends on the type of roof you have.

Here’s what we recommend, based on your roofing material:

  • Shingle Roofs: The IronRidge Flashfoot 2
  • Metal Roofs: S-5! makes a variety of clamps that accommodate standing seam, corrugated and trapezoidal metal roofs.
  • Tile Roofs: Quick Mount offers tile hooks and tile replacements to match your roof design.

Ground Mount

Ground mounts allow you to install panels anywhere on your property. The panels can be installed to face directly into the sun during peak hours, which ensures your system is as efficient as possible.

You can also mount your system on adjustable pole mounts. These work well in high snow regions because you can raise your system off the ground where snow accumulates. You can also adjust pole mounts to a steeper tilt angle, which helps shed your panels shed snow in the winter.

Pole mounts cost more than a fixed ground mount, but work wonders in the right situation.

Questions? Chat with us!

Todd built his own 3 kW solar system to power his Northern California home, where he lives off the grid with his wife and children. Todd and the rest of the Wholesale Solar team are here to answer any questions you have about designing a system that will fit your needs. Give us a call—we’re here to help.

How much will my system cost?

Use our solar cost calculator to judge where an off-grid system fits in your budget. Calculate your appliance needs or punch in your monthly energy use. We’ll estimate how much it will cost to build a system that covers your energy needs.

Of course, the calculator can only give you a ballpark figure. It’s challenging to account for usage peaks and lulls in production, especially in an off-grid setting. Our design techs can help you anticipate these challenges and build a solution to keep you running year-round.

We turn DIY enthusiasts into solar experts.

Still doing your research? Awesome – we love to talk to people who know their stuff. Our guides will help you design and build your off-grid system from start to finish.
