Complete Off-Grid Solar Kit 6.5kW 48V 120V/240V 10.24kWh LiFePO4 6×450W Solar Panels (SGK-65PRO)

Solar Power System For Shed — 6.5kW 450W Complete 120V/240V System

The most capable solar power system for shed and off-grid residential use in the compact kit class — the SGK-65PRO steps up from 5kW to 6.5kW of split-phase 120V/240V output with 6 × 450W monocrystalline solar panels, 10.24kWh of LiFePO4 battery storage with Bluetooth monitoring, a 6.5kW 48V inverter and all essential mounting hardware. The split-phase 120V/240V output is the specification that distinguishes the SGK-65PRO from 5kW 120V-only alternatives — enabling the simultaneous operation of 240V appliances (well pumps, air conditioners, water heaters) alongside standard 120V circuits in the same solar system. For solar power for garden shed conversions, outbuildings fitted with 240V tools or small homes requiring genuine split-phase capability, this is the system that delivers it at compact kit pricing.

System Specifications

120V/240V Split Phase — The Key Upgrade

The most important specification difference between the SGK-65PRO and its 5kW 120V counterparts is the split-phase 120V/240V output. Split-phase capability enables the simultaneous operation of 240V loads — equipment and appliances that operate at the higher North American residential voltage — alongside standard 120V loads from the same inverter system.

For a solar power system for shed that needs to run a 240V table saw, a well pump, a 240V compressor or workshop welding equipment, the SGK-65PRO’s split-phase output is not optional — it is the essential specification. Five-kilowatt 120V-only systems cannot power these loads regardless of their battery size or panel count.

For solar power for garden shed conversions where the shed functions as a fully equipped workshop, studio or living space, the SGK-65PRO provides the electrical equivalence of standard grid power — every 120V and 240V outlet and appliance operates exactly as it would on utility electricity.

6×450W Solar Array

Six 450W monocrystalline panels deliver 2,700W of generation capacity — producing approximately 10–16kWh daily under 4–6 hours of peak sun. The 450W panel specification delivers 21.6% more daily generation than equivalent 6-panel 370W arrays — providing more reliable daily battery recharge across variable irradiance conditions typical of year-round operation.

10.24kWh Bluetooth LiFePO4 Battery

Four 200AH LiFePO4 batteries with Bluetooth provide 10.24kWh of storage with real-time smartphone monitoring. LiFePO4 chemistry’s flat discharge curve means the inverter operates at consistent efficiency throughout the battery discharge cycle — maintaining appliance performance whether the battery is at 90% or 20% state-of-charge.

Solar Panel for Small House Applications

The SGK-65PRO is equally well-suited as a solar panel for small house applications as it is for shed and outbuilding power. At 6.5kW continuous output with 120V/240V split-phase capability and 10.24kWh of daily-rechargeable storage:

• Studio and tiny homes (under 600 sq ft) with efficient appliances
• Annexes and granny flats requiring genuine whole-circuit power
• Container homes and modular dwellings off-grid
• Rural small homes where grid connection cost is prohibitive
• Vacation properties requiring full residential electrical capability

For a solar panel for small house installation that needs genuine split-phase power — not the limited 120V-only output of entry-level 5kW systems — the SGK-65PRO delivers the electrical specification without requiring the investment of a 10kW system.

Expandability

Additional batteries increase storage beyond 10.24kWh. Additional 450W panels increase daily generation. The 6.5kW inverter supports parallel operation of multiple units in single-phase, split-phase or three-phase configurations. The SGK-65PRO is a scalable foundation for systems that grow beyond their initial specification.

FAQ

What makes the SGK-65PRO the best solar power system for shed installations? The SGK-65PRO’s split-phase 120V/240V output is the defining advantage over 5kW 120V-only solar power systems for shed use. It enables 240V workshop tools, well pumps and appliances to operate from the same solar system as standard 120V circuits — providing complete electrical capability that 120V-only systems cannot deliver regardless of their wattage.

What is the difference between this system and a 5kW solar kit for shed? The SGK-65PRO provides 6.5kW versus 5kW output, split-phase 120V/240V versus 120V-only capability and the complete breaker package included. The 1.5kW output increase and 240V capability make it appropriate for applications that require 240V loads — workshop equipment, well pumps, air conditioners and water heaters — that cannot be powered by 120V-only 5kW configurations.

Is this suitable as solar power for garden shed converted to a workshop? Yes — the SGK-65PRO is the appropriate specification for solar power for garden shed installations where the shed functions as a fully equipped workshop. Split-phase 120V/240V output handles 240V workshop tools and equipment. Six 450W panels provide 2,700W of generation. Ten-point-two-four kWh of LiFePO4 storage keeps power available between solar generation periods.

Can this system work as a solar panel for small house? Yes — the SGK-65PRO is well-suited as a solar panel for small house applications including studio homes, tiny houses, container dwellings and small annexes up to approximately 600 sq ft. The 6.5kW split-phase output handles all standard residential circuits and 240V appliances. The 450W panel array provides reliable daily recharge. LiFePO4 storage with Bluetooth monitoring provides transparency and control.

What protection components are included with this solar power kit? The SGK-65PRO includes a 200A DC breaker and a 25A PV breaker — the essential circuit protection components for the DC battery and PV input circuits. These components are required for safe system operation and are included in the kit, eliminating the need for separate hardware sourcing.
