System Specifications

450W Bifacial N-Type Panels

The SGK-12MAX uses 450W Bifacial N-Type monocrystalline panels — the same advanced cell architecture available in the premium pallet products. N-Type silicon delivers lower light-induced degradation and better temperature coefficient performance than P-Type PERC alternatives. The bifacial construction captures irradiance from both panel faces — increasing annual energy yield without increasing system footprint.

For a pv panel kits buyer comparing this specification against standard monocrystalline kits, the N-Type bifacial panels in the SGK-12MAX deliver meaningfully more energy per panel over the system lifetime — an important consideration when the kit represents a multi-year energy independence investment.

10.24kWh LiFePO4 Battery with Bluetooth

The 4 × 200AH LiFePO4 batteries provide 10.24kWh of usable storage — enough to power average household loads through the night and into morning before solar generation resumes. Bluetooth connectivity enables real-time state-of-charge monitoring, battery health tracking and system status access from a smartphone — eliminating the guesswork around available energy reserves.

LiFePO4 chemistry provides the longest cycle life of any commercially available battery technology at this price point, with safe, stable operation across ambient temperature ranges typical of residential installations.

12kW 48V Inverter

At 12kW continuous output with 120V/240V split-phase capability, the inverter in this off grid solar system kit handles every significant load in a well-sized residential property simultaneously. Split-phase output means no compromise — 240V appliances and 120V appliances operate on the same system in exactly the same way they would on utility power.

The 48V DC bus voltage minimises wiring losses between batteries and inverter, and the dual 100A MPPT charge controllers efficiently harvest maximum available solar generation from the 12-panel array across the full daily irradiance profile.

Installation Components

This solar installation kit includes everything required to mount panels, connect the system and commission the installation:

• Mounting Z-brackets for 12 panels — compatible with standard composition shingle and metal roofing
• 50ft solar extension cables for each PV string from panels to inverter
• Battery-to-MPPT controller cables
• 200A DC main breaker and 25A PV breakers for system protection

No separate racking purchase, cable sourcing or hardware runs required before installation can begin.

What Can This System Power?

A 12kW inverter with 10.24kWh battery and 5,400W solar array supports:

• Refrigerator and freezer
• Air conditioning (single unit)
• Washer
• Water pump
• Lighting throughout the home
• TV and entertainment systems
• Computer and office equipment
• Power tools (intermittent)

This is an off grid solar power system sized for genuine residential energy independence — not a limited-load backup system.

FAQ

What is included in this solar panel kit with battery and inverter? This solar panel kit with battery and inverter includes a 12kW 48V 120V/240V inverter, 2 × 100A MPPT charge controllers, 12 × 450W Bifacial N-Type monocrystalline solar panels, 4 × 200AH LiFePO4 batteries with Bluetooth, mounting Z-brackets, 50ft extension cables, battery-to-MPPT cables, a 200A DC breaker and 25A PV breakers. Every essential component for a complete off-grid solar power installation is included.

Why does this off grid solar kit use N-Type bifacial panels? N-Type bifacial panels deliver superior long-term energy yield compared to standard P-Type PERC monocrystalline alternatives. N-Type silicon has lower light-induced degradation — maintaining rated output more consistently across the system lifetime. Bifacial construction adds rear-face irradiance capture for additional annual yield. For an off grid solar kit representing a long-term energy independence investment, the N-Type bifacial specification maximises the energy value returned from every panel.

What is the daily energy production of this off grid solar kit? With 5,400W of solar panels and approximately 4–6 hours of peak sun, this kit solar energy system generates 21–32kWh of solar energy per day under typical conditions — significantly more than the 10.24kWh battery capacity, ensuring batteries charge fully each day with power available for immediate loads during daylight hours.

Can this system be expanded after initial installation? Yes — additional batteries can be added to increase storage capacity beyond the initial 10.24kWh. Additional solar panels can be connected to increase daily generation. The inverter platform supports parallel operation of multiple units for increased output if system load requirements grow beyond the initial 12kW rating.

Is this an off-grid solar system packages with batteries suitable for cabins? Yes — the SGK-12MAX is one of the most capable off-grid solar system packages with batteries available at this investment level for cabin and remote residence applications. At 12kW inverter output, 10.24kWh storage and 5,400W solar generation, this system comfortably covers the energy needs of a well-equipped cabin including air conditioning, refrigeration, water pump and entertainment systems.
