Cabin Solution (2560W | 19.2kWh)

2.5kW Cabin Solar Kit for Off Grid Tiny Homes and Full Time Small Houses

If you want your off grid tiny home or small cabin to feel like a real home, not a weekend shed, the Renogy 2.5kW Essential Plus Kit gives you a full size 2.5kW cabin solar kit with a 19.2kWh battery bank and a 48V 3500W inverter charger. It is built to run a serious load out in the woods or on your land, keeping lights, fridge, pumps, internet and small AC or heat solutions powered day after day. Backed by 13 years enabling energy freedom and over 10 million solar panels sold, it is designed for people who want independence without constant power anxiety.

Off Grid Tiny Home Solar Kit With Room To Live

This 2.5kW Essential Plus Kit is a step up for cabins and tiny homes that see regular or full time use. The 2.5kW N type solar array brings in enough daily energy to cover typical small home loads when the sun is cooperating, while the 19.2kWh AGM battery bank gives you a deep reserve for nights and bad weather. The 48V 3500W pure sine inverter charger ties it all together, running standard 120V appliances and managing charging from both solar and a backup generator or grid when available.

For the resilient suburban homeowner, it turns a family cabin into a comfortable, outage proof retreat instead of a powerless shell when storms hit. For the off grid homesteader, it is a strong backbone system you can build a life around, not just a weekend camping setup.

2.5kW N Type Solar Panels For Limited Roof Space

Roof space is always tight on tiny homes and cabin shells, which is why this kit uses high efficiency 320W N type monocrystalline panels. Each module delivers about 320W at STC with 22.2 percent efficiency, so you get more production from every square foot of roof.

Electrical performance is proven: open circuit voltage around 43.82V, operating voltage about 37.85V at 8.46A, with a 1000V DC maximum system voltage and 20A max series fuse rating. The panels are built to handle real weather, from minus 40°F to 185°F, and each one measures roughly 64.6 by 34.7 by 1.4 inches at 32.9 pounds, easy to handle during install.

You get the same trusted panel across the kit, protected by a 10 year output, material and workmanship warranty, so you are not mixing and matching unknown modules to hit your power target.

19.2kWh AGM Battery Bank For Serious Cabin Storage

Power is only as good as your storage. This kit uses eight 12V 200Ah AGM batteries, giving you a total 19.2kWh battery bank. That is the kind of capacity that keeps your tiny home or small cabin running through long nights, cloudy stretches and shoulder seasons when solar alone would otherwise feel thin.

Each 12V 200Ah AGM battery is rated at 200Ah (20 hour rate to 10.5V) with around 500 cycles at 50 percent depth of discharge. They can be wired in series and in parallel up to four in each string, and handle up to 60A of continuous charging current. Physical dimensions are about 20.6 by 9.4 by 8.8 inches, with each battery weighing roughly 127.9 pounds, so they sit like a permanent fixture in a dedicated battery space, the way a serious off grid system should.

For a prepared family, that much storage means the fridge, pressure pump, lights, router and key outlets can stay online through a rough weather window without constantly firing a generator. For an off grid homestead, it gives you enough buffer to work, cook and live without counting every switch every second.

48V 3500W Inverter Charger For Real Home Loads

At the center of the system is the 48V 3500W pure sine wave solar inverter charger. It converts your 48V battery bank to clean 120V AC power, the same form most home appliances expect, and manages both solar charging and AC charging from grid or generator.

It delivers 3500W of rated power with peak efficiency over 95 percent. AC input is 120V, with a working range from 85 to 140V AC, and output is a stable 120V AC, adjustable between 100 and 120V in 5V steps to match your setup. On the solar side, it takes up to 4400W of PV input, with 80A max PV charging current and a 150V max PV input voltage, giving you room for expansion.

The housing is compact enough for a tidy power wall, at about 17.51 by 12.99 by 4.88 inches, and it comes ready for Bluetooth remote monitoring via the included BT 2 module, so you can see production, loads and battery state from inside the cabin or tiny home without digging into the wiring closet.

Complete 2.5kW Cabin Solar Kit With Protection And Wiring

Instead of chasing individual parts, this 2.5kW cabin solar kit ships with the major components and protections already thought through. You get the 320W N type panels, combiner box, 40 ft 10AWG panel to controller adaptor cables, DC breaker box with 16A and 50A miniature DC breakers, and a 160A molded case DC breaker for battery side protection.

Battery and inverter cabling is included, with 1AWG copper battery interconnects and 1AWG inverter cables, as well as tray cables to link the battery bank to the charge controller. Every piece is sized to work together, so you are not left guessing wire sizes or breaker ratings when you are hours from the nearest supply house.

For the homeowner or homesteader who would rather spend time enjoying the land than debugging mis matched components, that completeness matters.

If your cabin is smaller and used just on weekends, or larger with heavier loads like mini split heat pumps and shop tools, you may want a different balance of solar, storage and inverter size. Use this 2.5kW Essential Plus Kit as the benchmark for a full featured off grid tiny home system.
