Compact 3.5kw Off Grid Solar System

Ultra-Compact Design for Space-Limited Settings
Slim Solar Panels: Equipped with 6–7 high-efficiency 590W dual-glass monocrystalline panels (23.5% conversion rate), each measuring just 65” x 39” x 1.2”—20% smaller than standard 350W panels. Their compact size fits easily on tiny home rooftops, RVs, cabin awnings, or even wall mounts, making them ideal for locations with limited space.
All-in-One Power Hub: The inverter, charge controller, and battery combine into a single compact unit (18”L x 12”W x 10”H)—small enough to tuck under a cabin counter, in an RV storage compartment, or on a shed shelf. No separate bulky components, reducing installation space by 40% compared to traditional off-grid systems.

Products Description

1~30KW Solar Energy Systems

3.5kW Output for Off-Grid Essentials

Continuous & Surge Capacity: Delivers 3.5kW continuous AC power (surge up to 7kW) to run off-grid necessities: a small refrigerator, LED lighting, laptop, TV, coffee maker, and even a 5,000BTU air conditioner. The pure sine wave inverter (97% efficiency) ensures stable 110V/220V power, safely powering sensitive devices like CPAP machines or drones.

Efficient Energy Harvest: Despite their size, the 590W panels generate 10–14kWh/day in sunny conditions-enough to cover 100% of energy needs for a 200 sq.ft tiny home or weekend cabin, with excess stored in the battery for nighttime use.

Compact Battery Storage with Longevity

7–10.5kWh High-Density Battery: A lightweight (45 lbs) LiFePO4 battery with 7–10.5kWh capacity fits inside the all-in-one hub, offering 5.6–8.4kWh of usable energy (80% DoD). It provides 8–12 hours of power for essentials during nighttime or cloudy weather, with 3,000+ charge cycles (10+ year lifespan).

Integrated BMS: A built-in Battery Management System optimizes charging/discharging to prevent overuse, ensuring the compact battery lasts as long as larger standalone units-critical for off-grid setups where replacement is inconvenient.
