24 Volt Solar Power Kits

24 Volt Solar Panel Kit Options: Complete Systems for Trailers, Tiny Homes and Cabins

A 24 volt solar panel kit bundles panels, a charge controller, lithium batteries and an inverter that all speak the same voltage, so you unpack and wire rather than shop for parts. The best 24 volt solar panels for a small build are the ones that arrive matched to the controller and battery in the box, because a 24V bank halves the current of a 12V system at the same power, which means thinner cable, less heat and a 3,000W inverter that runs comfortably. This class fits a travel trailer with a rooftop AC, a tiny home, a workshop or a cabin that runs a fridge, lights, pump and tools.

The collection holds 4 kits from Rich Solar and Sungold Power, priced from $2,485 to $4,700. Three are in stock; the Sungold Power 6,000W 24V kit with 10.24kWh of battery and six 370W panels is sold out at the moment.

How to choose a 24V kit

• Array size. Panel watts set how much you make per day. The Rich Solar 1600 Watt 24V Complete Solar Kit ships eight MEGA 200W panels for a 1,600W array; the Rich Solar 3000 Watt 24V Complete Solar Kit with 1,200W Array ships six for 1,200W; the Sungold Power SGKT-3PRO ships four 200W panels for 800W. Cloudy regions and winter use push you toward the larger array.
• Battery bank. All three in-stock kits carry 5.12kWh of LiFePO4 storage, roughly two evenings of fridge, lights, pump and TV. The Rich Solar kits use two ALPHA 4 batteries; the Sungold kit's battery is Bluetooth-enabled for monitoring from a phone.
• Inverter output. Every in-stock kit here has a 3,000W inverter, enough for a microwave, a coffee maker or a 13,500 BTU RV air conditioner one at a time. The Sungold unit puts out 120V; the sold-out 6,000W kit was the 120/240V option for a cabin with a well pump.
• Charge controller. The Rich Solar kits include a separate 60A MPPT controller; the SGKT-3PRO builds an 80A MPPT charger into the inverter, which saves a box on the wall and some wiring.
• Roof space. Eight rigid 200W panels need a long trailer roof or a ground rack; four fit a van or a small shed roof.

Sizing tips

• Run your appliance list and ZIP code through the Solar Kit Calculator before choosing between 800W, 1,200W and 1,600W of panels. The battery is the same in all three kits, so the array decides how quickly it refills.
• Count surge loads. A rooftop AC compressor or a shop saw needs the 3,000W inverter's headroom; add up running watts and keep a margin.
• Plan for 24V accessories. A 24 volt solar panel system needs 24V lights and pumps, or a DC-DC converter for 12V gear you already own.
• Mount rigid panels with an air gap and tilt them 30 to 40 degrees at a cabin; on a trailer roof flat mounting is fine in summer.
• Keep the battery indoors or in an insulated bay in winter; lithium does not charge below freezing.

Frequently asked questions

Why choose 24V over 12V? At 3,000W, a 12V inverter draws about 250A; a 24V inverter draws about 125A. Thinner wire, smaller fuses and cooler connections make 24V the practical choice above 2,000W.

Can I add panels to these kits later? The Rich Solar kits include a 60A MPPT controller and the Sungold kit an 80A one; the controller's current rating sets the ceiling. Ask us before expanding and we will check the numbers for your kit.

Do I need an electrician? For a trailer or van, a careful DIYer can install these. For a cabin tied to house wiring, use a licensed electrician for the AC side and any permit.

Kits ship free to the mainland US from our brand partner warehouses, usually within a few business days, with 30-day returns. Call us if you want help deciding between the 1,200W and 1,600W arrays for your location.
