Off-Grid Solar Kit 10kW 10×550W Panels 20.48kWh LiFePO4 Battery 48V 120V/240V (SGM-10K20)

Off Grid Solar Kit 10kW — 550W Panels 20.48kWh Complete System

The off grid solar kit that covers cabins, shops and full residential homes without compromise — the SGM-10K20 delivers 10kW of split-phase 120V/240V off-grid power with 10 × 550W monocrystalline solar panels, 20.48kWh of LiFePO4 battery storage, a 10kW 48V inverter supporting up to 6-unit parallel expansion, and all necessary mounting hardware and cables in a single complete purchase. The solar array produces approximately 22kWh per day based on four hours of peak sun — enough to keep the battery bank full and power daytime loads simultaneously in the vast majority of installation conditions. Built for expansion from day one and priced for serious buyers who want a real off grid solar system without building it piece by piece.

System Specifications

550W High-Output Solar Panels

Ten 550W monocrystalline panels deliver 5,500W of generation capacity — producing approximately 22kWh daily under four hours of peak sun. At 550W per panel, this array achieves the same total generation as a 14-panel 400W array — reducing roof footprint, mounting hardware requirements and installation labour. For off grid solar panels buyers comparing value across different panel-count configurations, fewer high-wattage panels consistently deliver better installation economics per kWh of daily generation.

The 550W specification is particularly well-suited to tiny home solar panels installations on compact structures where available mounting area is limited — extracting maximum generation from every square foot of available roof space.

20.48kWh LiFePO4 Battery Storage

Four 100AH 51.2V LiFePO4 batteries provide 20.48kWh of storage — the largest battery bank available in a 10kW compact kit configuration. This storage level provides:

• Full overnight coverage for residential loads through a complete 8–10 hour overnight period
• Multi-day cloudy-weather resilience before generator backup is required
• Reduced depth-of-discharge per cycle, extending battery service life
• Capacity headroom for energy-intensive appliances running simultaneously

LiFePO4 chemistry delivers the flat discharge curve, thermal stability and long cycle life that makes it the standard for serious off grid solar system installations at this investment level.

10kW 48V Inverter

The 10kW 48V split-phase inverter handles every standard North American residential load simultaneously — air conditioners, well pumps, refrigerators, washers, workshop tools, office equipment and full-home lighting within the 10,000W continuous output rating. The 120V/240V split-phase configuration means no electrical adaptation is required — every outlet and circuit in the home operates exactly as it would on utility power.

The inverter supports up to 6 units in parallel — enabling output expansion from 10kW to 60kW without replacing the core system hardware.

22kWh Daily Generation

Twenty-two kilowatt-hours per day from four hours of peak sun is the generation headline that makes the SGM-10K20 one of the most productive mid-range off grid solar kit configurations available. Most North American homes consume between 20–30kWh daily — placing this system at the lower end of average consumption, with solar generation meeting or matching total daily need in well-insulated, energy-conscious households.

For cabins and weekend properties with moderate load profiles, 22kWh of daily generation provides substantial surplus — keeping batteries fully charged and leaving energy headroom for high-consumption days without any demand reduction.

Expandability

Add more batteries to increase storage beyond 20.48kWh. Add more panels to increase daily generation. Connect up to 6 identical inverters in parallel for single-phase, split-phase or three-phase output expansion. The SGM-10K20 is a foundation system — designed to grow with your energy needs rather than create a fixed ceiling.

FAQ

What is included in this off grid solar kit? This off grid solar kit includes a 10kW 48V 120V/240V split-phase inverter, 10 × 550W monocrystalline solar panels, 4 × 100AH LiFePO4 batteries (20.48kWh total), 50ft solar extension cables, mounting Z-brackets and DC and PV breakers. Every essential component for a complete off-grid solar power installation is included.

How much does this off grid solar system produce daily? This off grid solar system generates approximately 22kWh per day based on four hours of peak sun exposure. Production varies with local solar irradiance — locations with longer peak sun hours (5–6 hours common in the US sun belt) produce proportionally more daily generation.

Is this kit suitable as tiny home solar panels? Yes — the SGM-10K20 is well-suited as a tiny home solar panels solution. At 10 × 550W panels, the array achieves high generation from a compact 10-panel footprint — important for tiny homes where available roof or ground mounting area is limited. The 10kW inverter provides substantially more than enough output for the loads of a well-equipped tiny home.

Can I run air conditioning on this off grid solar kit? Yes — the 10kW split-phase 120V/240V inverter handles single or dual residential air conditioning units alongside other household loads within the 10,000W continuous output rating. The 20.48kWh battery provides runtime through the night when solar is unavailable.

How do I expand this off grid solar system in the future? Add more LiFePO4 batteries to increase storage beyond 20.48kWh. Add additional 550W panels to increase daily generation. Connect up to 6 identical inverters in parallel for expanded output in single-phase, split-phase or three-phase configurations — scaling from 10kW to 60kW.
