Off-Grid Solar Kit 10kW 48V 120V/240V 20.48kWh LiFePO4 12×415W Solar Panels (SGM-10M2T)

Off Grid Solar Power Systems — 10kW Dual Inverter 415W Complete System

The best off grid solar power systems combine flexible inverter architecture with proven solar panel specifications and robust battery storage — and the SGM-10M2T delivers all three. This complete 10kW off-grid kit features two 5,000W WiFi-enabled inverters operating in split-phase 120V/240V configuration, 12 × 415W monocrystalline solar panels, 20.48kWh of LiFePO4 battery storage and all mounting hardware. The dual-inverter design provides built-in redundancy and the flexibility to reconfigure between single-phase and split-phase operation — producing approximately 20kWh per day from four hours of peak sun, sufficient to run air conditioners, well pumps, refrigerators, workshop tools and full home loads simultaneously.

System Specifications

Dual WiFi Inverter Architecture

The SGM-10M2T’s defining specification is its dual-inverter design — two 5,000W WiFi inverters operating in coordination rather than a single 10,000W unit. This architecture provides three advantages that single-inverter off grid solar power systems cannot match.

First, built-in redundancy. If one inverter requires service, the system continues operating on the remaining 5kW unit — maintaining partial power availability without a complete system outage.

Second, operational flexibility. The dual-inverter setup can be configured for single-phase 120V output from either unit independently, combined split-phase 120V/240V operation, or three-phase 208V operation when connected with additional units — accommodating multiple electrical configuration requirements from the same hardware.

Third, enhanced expandability. Each 5kW inverter supports up to 6 units in parallel. The two-inverter SGM-10M2T foundation can be expanded to a combined 60kW maximum output — far beyond what a single expandable inverter platform can achieve.

The WiFi connectivity in both inverters enables real-time system monitoring from any smartphone — solar generation, battery state-of-charge, load consumption and system alerts accessible anywhere with internet connectivity.

12×415W Solar Array

Twelve 415W monocrystalline panels deliver 4,980W of total generation — producing approximately 20kWh daily under four hours of peak sun. The 12-panel array in this off grid solar power systems kit is one of the most commonly deployed configurations for full residential off-grid applications — large enough to cover average household consumption while remaining manageable for standard residential rooftop or ground-mount installation.

The included 50ft extension cables and Z-bracket mounting hardware support direct rooftop installation on standard composition shingle and metal roofing without additional racking purchase.

20.48kWh LiFePO4 Battery

Four 100AH 51.2V LiFePO4 batteries provide 20.48kWh of storage — matching the battery capacity of the SGM-10K20 at identical storage with a different solar panel count and inverter architecture. At 20.48kWh, this system provides full overnight coverage for standard residential loads and buffer capacity for consecutive cloudy days without generator use.

Off Grid Inverter Performance

The off grid solar inverter specification in this system — two WiFi-enabled 5kW 48V units in split-phase configuration — delivers 10kW of continuous output at 120V/240V. Every standard North American residential load operates without modification: air conditioners and well pumps on 240V, standard outlets and circuits on 120V, all from the same inverter system simultaneously.

Understanding the quality of the off grid supplies included in this kit — certified inverters, LiFePO4 batteries and grade-A monocrystalline panels — matters as much as the wattage specification. The SGM-10M2T uses professional-grade components throughout — this is not an entry-level kit built to a price point. These are off grid solar products that professional installers and experienced DIY builders reach for when reliability over the long term matters more than initial cost minimisation.

Expandability

Each 5kW inverter supports up to 6-unit parallel operation. Connect additional inverters for output expansion from 10kW toward 60kW total. Add battery banks for storage beyond 20.48kWh. Add panels for generation increase. The dual-inverter architecture provides a more capable expansion platform than single-inverter systems at equivalent initial output.

FAQ

What are off grid solar power systems? Off grid solar power systems are complete energy generation and storage packages that provide electricity independently of the utility grid. They combine solar panels (generation), batteries (storage), an inverter (DC to AC conversion) and charge controllers — producing all the electricity a home, cabin or facility needs from sunlight alone. The SGM-10M2T is a complete 10kW off grid solar power system including all essential components in one purchase.

Why does this system use two inverters instead of one? The dual-inverter design provides built-in redundancy, operational flexibility between single-phase and split-phase configurations, and a superior expansion platform — each inverter supporting up to 6 additional units in parallel. If one inverter requires service, the system continues on the remaining unit. For off grid solar power systems where reliability is paramount, dual-inverter architecture significantly reduces the risk of a complete system outage.

What is the off grid solar inverter specification? The off grid solar inverter specification in the SGM-10M2T consists of two 5,000W 48V DC 120V/240V WiFi-enabled inverters. Each unit supports up to 6 additional inverters in parallel and provides WiFi remote monitoring. In split-phase coordination, the two inverters deliver 10kW of combined continuous output at 120V/240V — the standard North American residential electrical configuration.

What off grid supplies and hardware are included? Off grid supplies included with the SGM-10M2T cover all essential installation hardware: 2 × 50ft solar extension cables, mounting Z-brackets for 12 panels, DC breakers and PV breakers. No separate hardware sourcing is required for standard residential rooftop or ground-mount installation.

What off grid solar products complement this system? Off grid solar products that complement the SGM-10M2T include additional LiFePO4 battery banks for storage expansion, additional 415W or 550W solar panels for generation increase, and additional 5kW WiFi inverters for output expansion. All expansion components can be added at any time without requiring a system architecture redesign.
