About The 13KW N-Type Bifacial System

The off grid solar SGR-13K25E stands apart from other 13KW kits in this range through its use of 450W bifacial N-Type monocrystalline panels — the premium solar panel technology delivering the highest per-panel output lowest degradation rate and best low-light performance available in the current residential solar market. The 22-panel array generates approximately 30KWH per day at 4 hours of peak sunlight — meeting the energy needs of most households including those running air conditioning well pumps and other high-demand appliances simultaneously.

The dual 6500W inverter architecture delivers 13KW of combined 120/240V split phase output — with parallel expansion capability to 6 inverters enabling system scaling from 13KW to 39KW as energy requirements grow.

Off Grid Solar Architecture

The off grid solar SGR-13K25E manages energy through the dual-inverter platform:

• 22 x 450W N-Type bifacial panels generate 9900W DC input during daylight
• Dual 6500W inverters convert DC to 120/240V AC split phase output
• Loads powered directly from solar generation during peak sun hours
• Surplus generation charges the 25.6KWH LiFePO4 server rack battery bank
• Battery bank powers loads overnight and during insufficient generation periods
• System expandable with additional panels batteries and inverters

N-Type Bifacial Panels Advantage

The 450W bifacial N-Type monocrystalline panels in the SGR-13K25E deliver the premium performance characteristics most valuable in serious long-term off-grid installations:

• Bifacial Yield — rear surface captures reflected ambient light adding meaningful generation above nameplate rating
• N-Type Efficiency — phosphorus-doped N-Type cells achieve higher base conversion efficiency than P-Type alternatives
• Lowest Degradation — N-Type cells resist light-induced degradation most effectively — maintaining higher output over decades of off-grid operation
• Low-Light Performance — superior generation during dawn dusk and overcast conditions — maximising generation hours per day in variable weather climates

Flexible Expansion

The SGR-13K25E is designed as a scalable long-term platform:

• Additional 450W panels can be added to increase daily generation
• Additional LiFePO4 batteries expand storage capacity
• Additional 6500W inverters can be paralleled to 6 units in single split or three-phase configurations
• The enclosed battery cabinet supports up to 6 batteries — one additional module beyond the included 5
