Take Control of Your Energy Independence with the Ultimate 15.84kW DIY Solar Powerhouse

High-capacity solar system designed for large homes in the United States, properties with central air, homesteads, and projects requiring total autonomy, resilience against power outages, and significant reduction in electricity bills. Includes a 15.84kW photovoltaic array, the EG4 FlexBoss21 hybrid inverter, the GridBoss smart hub, a 32kWh LFP battery bank, and the Sinclair SkyRack HD mounting system made in the USA.

🔋 LFP Battery Bank — 32kWh 20+ year lifespan — 10,000 cycles @ 80% DoD Industrial LiFePO₄ chemistry

10,000 cycles @ 80% DoD (premium certification)

20+ year service life with daily cycling

Modular architecture

High thermal stability

Ideal for continuous off-grid use

Integrated industrial BMS

🏠 Ideal for US Properties 2,000–4,000 sq ft homes

Homes with 2–3 ton central air

Dwellings with moderate electric heating

Properties with water wells

Off-grid workshops and homesteads

Families of 3–6 people with high consumption

🔌 Actual System Capabilities With 16,000W continuous and 32kWh LFP, this system can power:

2–3 ton central air

Heat pumps and light electric heating

1/2–1 HP well pump

Refrigerator + freezer

Electric dryer (occasional use)

LED lights, fans, TV, computers

Internet, routers, cameras

Light to medium workshop tools

🔋 Realistic Autonomy (32kWh LFP) Full house without A/C: 24–36 hours

2–3 ton central air: 6–10 hours at night

Full house with moderate A/C: 12–20 hours

Workshop/homestead: 8–14 hours

☀️ Real Solar Production in the USA (15.84kW) National average: 4.5 peak sun hours

Daily production: ~71 kWh/day

Monthly production: ~2,138 kWh/month

Summer: 80–95 kWh/day

Winter: 40–55 kWh/day

🏕 Is it suitable for 100% Off-Grid? ✔ Yes, in spring, summer, and autumn ❗ In winter, additional support is recommended Solar production drops in winter, so a generator is essential for full year-round off-grid living.

🔥 Optional Generator (Financable) DuroMax XP16000iHT Tri-Fuel Inverter This generator is optional but recommended for:

Total off-grid in winter

Consecutive cloudy days

Prolonged heavy loads

Fast recharging of the LFP bank

✔ Can be included in the total project balance ✔ Can be financed along with the solar system Recharge time for 32kWh bank: Approximately 4 hours using the FlexBoss21.
