Solar Kits for Every Power Need and Every Setup
Whether you are building a fully independent off-grid system, adding backup power to your home, or outfitting an RV for extended travel, the right solar kit makes the whole process dramatically simpler. Instead of sourcing panels, inverters, charge controllers, and batteries separately and hoping everything is compatible, a well designed solar kit gives you pre-matched components that work together from day one.
At Off-Grid Source, we carry solar kits for every application and budget, from compact portable setups to large scale whole home systems, all from brands we have vetted and stand behind.
Types of Solar Kits We Carry
Not all solar kits serve the same purpose. Here is a breakdown of what we offer so you can find what fits your situation:
-
Off-grid solar kits. Built for properties with no utility connection. These complete systems generate and store all the power you need independently, with LiFePO4 battery banks, pure sine wave inverters, and high efficiency solar arrays. Capacity ranges from around 3000W for smaller cabins up to 15,000W or more for full residential off grid living.
-
Hybrid solar kits. Generate and store solar energy while staying connected to the grid as a backup. A hybrid inverter manages all inputs simultaneously, prioritizing solar and battery power while drawing from the grid only when needed.
-
RV and mobile solar kits. Sized for the compact roof space and 12V or 24V systems common in motorhomes, camper vans, travel trailers, and boats. Includes flexible or rigid panels, MPPT controllers, and optional inverters for running AC devices on the road.
-
Cabin solar kits. Purpose built for remote cabins and off grid retreats that need reliable power for lights, a refrigerator, a water pump, and everyday electronics without grid access or generator noise.
How to Choose the Right Solar Kit
The right kit solar system depends on a few straightforward questions. What do you need to power? Are you on or off the grid? Is this a fixed installation or mobile use? Do you need AC output for standard appliances, or are your loads all 12V DC? Do you want room to expand later?
Most quality kits are designed to grow with you. If your energy needs will increase over time, look for systems with modular battery options and inverters that can be paralleled or upgraded down the road.
Shop Solar Kits From Brands We Trust
We carry solar kits from SunGold Power, Rich Solar, Sol-Ark, ACOPower, EcoFlow, Jackery, Anker SOLIX, Bluetti, and more. Every brand in our catalog has been evaluated for real world performance, honest specs, and reliable support. We do not list everything. We list what we would actually recommend.
Pricing is transparent with no hidden fees, and we are upfront about stock and lead times before you commit. If you find a lower price elsewhere, we will match it. Free shipping across the US and a 30 day return policy back that up.

Frequently Asked Questions About Solar Kits
What is included in a complete solar kit?
A complete solar kit typically includes solar panels, a charge controller, an inverter, battery storage, and the wiring and connectors needed to tie everything together. Some kits include all of these components pre-matched out of the box, while others are panel-and-controller bundles that assume you already have batteries and an inverter. Always check what is included before purchasing so you know exactly what you are getting and what you may still need to add.
What size solar kit do I need for my home?
It depends on your daily energy consumption and whether you are staying grid connected or going fully off grid. A small backup system for essential loads like a refrigerator, lights, and a router might need 2 to 5kWh of storage and 1,000 to 2,000W of solar. A full off grid home with higher daily loads typically needs 8kW or more of panels and 15 to 30kWh of battery storage. Our team can help you work through the sizing based on your actual usage rather than guesswork.
Can I buy solar kits for sale and expand them later?
Yes, and this is one of the most important things to consider when choosing a kit. Most quality systems in our catalog are designed to be modular, meaning you can add more panels, extra battery modules, or stack additional inverters as your energy needs grow. If you think you will want to expand later, prioritize systems that explicitly support scalability rather than fixed capacity configurations that cannot be upgraded.
What is the difference between an off grid solar kit and a hybrid solar kit?
An off grid solar kit operates completely independently from the utility grid. It generates, stores, and delivers all your power from solar and batteries alone. A hybrid kit stays grid connected and uses the utility as a backup or overflow source, managed by a hybrid inverter that automatically prioritizes solar and battery power first. Hybrid systems tend to be a better fit for homeowners who want backup resilience without fully cutting the utility connection, while off grid systems are the right choice for remote properties where the grid is not available.
Are solar kits difficult to install?
It depends on the kit type and your comfort level with electrical work. Portable solar generator kits that pair a power station with foldable panels require no installation at all. Fixed roof or ground mount systems with inverters and battery banks are more involved and typically benefit from at least some familiarity with DC wiring and electrical safety, or a professional installer for the final connections. Most kits in our catalog include wiring diagrams and documentation, and our team is available to answer installation questions before and after your order ships.
