System Specifications

450W Bifacial N-Type Panel Technology

The SGK-12MAX is built around 450W Bifacial N-Type monocrystalline panels — the advanced cell architecture that leads the current mainstream solar panel kits for home market on both efficiency and long-term performance.

N-Type silicon — phosphorus-doped rather than boron-doped — delivers inherently lower light-induced degradation (LID) than P-Type alternatives. This means the panels maintain closer to rated output throughout the system’s lifetime rather than experiencing the progressive performance decline associated with P-Type cells. Bifacial construction adds a transparent rear glass that captures irradiance reflected from the ground surface beneath the array — supplementing direct front-face output with rear-face gain of 5–25% depending on installation albedo.

For a residential solar panel kit investment that needs to deliver consistent performance across 25+ years, N-Type bifacial technology provides a measurably superior energy yield profile compared to standard PERC monocrystalline alternatives.

Dual 100A MPPT Charge Controllers

The SGK-12MAX includes two 100A MPPT (Maximum Power Point Tracking) solar charge controllers — a dual-controller configuration that provides two independent solar string inputs to the battery bank. MPPT technology continuously adjusts the electrical operating point of the solar array to extract the maximum possible power from the panels at all irradiance levels — improving energy harvest by 10–25% compared to PWM charge control, particularly during morning, evening and overcast conditions.

The dual-controller configuration allows the 12-panel array to be split into two independent strings — providing operational flexibility and ensuring that if one charge controller requires service, the system continues charging batteries from the remaining string.

10.24kWh Bluetooth LiFePO4 Battery

Four 200AH LiFePO4 batteries with Bluetooth provide 10.24kWh of storage accessible through real-time smartphone monitoring. Bluetooth visibility of state-of-charge, charge rate and battery health eliminates the guesswork around stored energy availability — a critical operational advantage for residential off-grid households managing daily energy budgets.

LiFePO4 chemistry provides 2,000–6,000+ charge-discharge cycles at standard depth-of-discharge — representing years of daily cycling with maintained capacity. This longevity is fundamental to the long-term economics of a home solar kits investment: battery replacement at year 3 or 5 eliminates much of the financial benefit of solar independence. LiFePO4 avoids this by delivering the full system lifetime the solar panels are rated for.

12kW 48V Solar System Performance

The 48V solar system architecture in the SGK-12MAX operates at 48V DC bus voltage — the residential off-grid standard that balances wiring efficiency, component availability and system scalability. At 48V, current levels in the DC wiring between batteries and inverter are substantially lower than at 12V or 24V for equivalent power — reducing wiring losses, enabling smaller cable gauges and simplifying the battery bank configuration.

At 12kW of continuous inverter output with 120V/240V split-phase capability, this system handles every significant residential load simultaneously — central air conditioning, well pump, electric water heater, washer, dryer, refrigerator, full lighting and entertainment systems within the 12,000W continuous rating.

Residential and Commercial Applications

The complete home solar system SGK-12MAX is designed for:

• Primary off-grid residences requiring full household load coverage
• Cabins and seasonal properties seeking complete energy independence
• Remote commercial locations with residential-equivalent power needs
• RV and mobile applications requiring permanent-grade solar infrastructure
• Agricultural properties requiring whole-facility off-grid power

The home solar kits specification — N-Type bifacial panels, LiFePO4 Bluetooth batteries, dual MPPT controllers, split-phase 120V/240V inverter and complete mounting hardware — delivers professional-installation-quality components in a DIY-accessible package.

FAQ

What is included in this residential solar panel kit? This residential solar panel kit includes a 12kW 48V 120V/240V split-phase inverter, 2 × 100A MPPT charge controllers, 12 × 450W Bifacial N-Type monocrystalline panels, 4 × 200AH LiFePO4 Bluetooth batteries (10.24kWh), mounting Z-brackets, solar extension cables, battery-to-MPPT cables, a 200A DC breaker and 25A PV breakers. Every essential component for a complete residential off-grid solar installation is included.

Why does this residential solar kit use N-Type bifacial panels? N-Type bifacial panels deliver superior long-term energy yield compared to standard P-Type PERC monocrystalline panels. Lower light-induced degradation maintains rated output more consistently across the system lifetime. Bifacial rear-face energy capture adds 5–25% above rated front-face output depending on installation albedo. For a residential solar panel kit representing a long-term home energy investment, N-Type bifacial specification maximises the energy value delivered over 25+ years.

What is the daily energy production of this pv panel kits configuration? This pv panel kits configuration of 12 × 450W N-Type bifacial panels delivers approximately 21kWh of daily generation under four hours of peak sun. In sun-belt locations with 5–6 hours of peak sun, daily production reaches 26–32kWh — covering average North American household consumption of 20–30kWh daily.

Is this a complete 48V solar system? Yes — the SGK-12MAX is a complete 48V solar system. The 48V DC bus voltage connects batteries, MPPT charge controllers and inverter in a unified 48V architecture that minimises DC wiring losses, enables efficient charge controller operation and provides a scalable platform for battery bank expansion.

What makes this a complete home solar system? A complete home solar system includes generation (panels), storage (batteries), conversion (inverter), charge management (MPPT controllers) and all installation hardware — in a single purchase that requires no additional component sourcing. The SGK-12MAX meets this definition fully: every component for a complete off-grid residential installation arrives in one kit.
