A 5kW solar power system comfortably covers essentials in a modest home, a large cabin, or a workshop. All six here are in stock from $3,145, led by Sungold Power 5,000W off-grid kits at 48VDC with 5.12 or 10.24 kWh of battery, plus a Rich Solar kit and a BigBattery system. The key choice is battery capacity, since it controls how long you can run after dark. Bigger storage costs more but extends your autonomy, so estimate your nightly energy use first.

5kW Solar System Kits: Complete Off-Grid Packages for Cabins and Small Homes

A 5kW solar system is the first size that runs a household rather than a campsite. The 5,000W inverter handles a refrigerator, well pump, microwave and a window air conditioner together, and the battery carries the essentials through the night. Every kit here bundles the inverter, a 48V LiFePO4 battery and, in most cases, the panels, so the parts are already matched for voltage and charge current.

The collection holds six packages from Sungold Power, Rich Solar and BigBattery. Prices start at $3,145 for a kit with 5.12kWh of storage and six 200W panels, sit between $4,782 and $4,958 for 10.24kWh kits with larger arrays, and reach $9,999 for a 6,500W Rich Solar system with 15.36kWh and sixteen panels.

Pricing a 5kW system with a battery? Our guide 5kW solar system with battery: price, daily output and sizing compares these kits with true 5 kW arrays, shows daily kWh by sun hours and explains how much battery a 5,000W inverter needs.

How to choose a 5kW solar kit

  • Battery capacity for your nights. The entry kit, the Sungold Power 5,000W Kit with 5.12kWh and 6 x 200W panels, suits a weekend cabin with lights, a fridge and a pump. Full-time living wants the 10.24kWh tier, which is where the SGM-5K10M, SGR-5KE and SGK-5PRO sit.
  • Array size sets recharge speed. Six 200W panels give 1,200W; six 415W panels give 2,490W. The Sungold Power SGK-5PRO with 2,700W of panels is the largest array among the 5,000W kits and refills its 10.24kWh battery on a shorter winter day than the others.
  • Output voltage. Every kit here, including the Rich Solar 6,500W Complete Off-Grid Kit, delivers 120V. If you need 240V for a well pump or dryer, step up to our 8kW systems.
  • Panels included or not. The HUSKY 2 10.24kWh Kit with Victron MultiPlus-II 5000 ships two batteries, the inverter/charger and a Cerbo GX monitor but no panels. It is the pick for RVs and mobile builds where the array is roof-mounted separately, and Victron's PowerAssist lets the batteries top up a small generator or shore connection.
  • Monitoring. The SGK-5PRO inverter is WiFi-enabled and the Victron kit reports through Cerbo GX, so you can watch charge and load from a phone; the other kits show data on the inverter panel.

Sizing tips

  • Run the Solar Kit Calculator with your appliances and ZIP code. It tells you whether a 5kw solar power kit with 1,200W of panels covers your winter, or whether you need the 2,490W to 2,700W arrays.
  • Count the nightly load, not the daily. A 10.24kWh battery covers roughly 8kWh of usable overnight draw; if a heat pump runs all night, you are in 15kWh territory.
  • Every kit is expandable. The Sungold packages are described as customizable with extra batteries and panels, so start with the kit and add a second 5.12kWh module when the budget allows.
  • Keep the battery indoors or in a conditioned space. Charging LiFePO4 below freezing is the most common cause of early failure in cabin systems.
  • A 5kw inverter still needs correctly sized cable and a fuse between battery and inverter; the Victron kit includes its monitoring hardware, but wiring is on you or your electrician.

Frequently asked questions

How much does a 5kW solar system produce per day? It depends on the array, not the inverter. The Rich Solar 6,560W kit is listed at roughly 23.6kWh per day; a 1,200W array on the entry Sungold kit yields a fraction of that, so pick the kit by panels as much as by inverter size.

Can I run central air on a 5kW solar kit? Not comfortably. A window unit or a small mini split is fine; central air and electric heat call for the 8kW class with 240V output.

Do I need a permit? For a permanent home installation, usually yes. Cabin and RV rules vary; check with your county before ordering and ask us for the spec sheets your inspector wants.

Kits ship free to the mainland US from brand partner warehouses, usually within a few business days, with 30-day returns. Call us with your load list and we will confirm which 5kW package fits.
