About The 13KW Off-Grid System
The off grid solar kits SGM-1320M is designed specifically for consumers seeking complete off grid solar independence for homes cabins and remote properties that need a serious inverter capacity without the complexity of a custom system design. The dual 6500W inverter architecture delivers 13KW of combined output — more than sufficient to run demanding residential loads simultaneously including air conditioning water pumping refrigeration and general household appliances.
The system produces approximately 17.7KWH per day under standard 4-hour peak sun conditions — covering the energy needs of most average-sized off-grid households when combined with the 20.48KWH battery bank that bridges overnight and low-generation periods. The expandable architecture supports up to 6 identical inverters in single-phase split-phase or three-phase arrangements — enabling capacity growth without system replacement as energy requirements evolve.
Off Grid Solar Living
The SGM-1320M is engineered specifically for consumers committed to solar panels for off grid living — delivering the robust inverter capacity battery storage and solar array needed to support a genuine full-time off-grid lifestyle without compromise:
- 13KW Inverter Output — handles high-demand loads including central HVAC units well pumps and workshop equipment simultaneously
- 17.7KWH Daily Generation — covers typical household daily consumption under standard sun conditions
- 20.48KWH Battery Storage — overnight autonomy for most household loads without grid supplementation
- Expandable Architecture — additional panels batteries and inverters can be added as the household grows or consumption increases
Solar Panels For Off Grid Living
Solar panels for off grid living in the SGM-1320M use 370W monocrystalline panels — a proven and reliable cell technology delivering consistent output across the range of weather conditions encountered in full-time off-grid living applications. The 12-panel array is sized to generate meaningful daily energy while remaining manageable for most residential rooftop and ground-mount installations.
Small Off Grid Solar System Comparison
The SGM-1320M sits above the small off grid solar system category — its 13KW dual-inverter architecture making it suitable for full-sized residential off-grid applications rather than the cabin shed and RV applications that smaller 6.5KW and under systems typically address. Consumers seeking a small off grid solar system for a single-room cabin or compact shed should consider the SGM-6510M in the 6.5KW single-inverter configuration.

Frequently Asked Questions
Q: What are the off grid solar kits SGM-1320M? The off grid solar kits SGM-1320M is a complete 13KW 48V dual-inverter off-grid system with 12 x 370W monocrystalline panels — 20.48KWH lithium storage — producing approximately 17.7KWH daily — expandable to 6 inverters in single split or three-phase configuration.
Q: What is the off grid solar daily generation capacity? The off grid solar SGM-1320M produces approximately 17.7KWH per day based on 4 hours of peak sunlight — sufficient to cover the daily energy needs of most average-sized residential off-grid applications when combined with the 20.48KWH battery bank.
Q: What solar panels for off grid living does this kit use? Solar panels for off grid living in the SGM-1320M are 370W monocrystalline panels — a proven and reliable cell technology delivering consistent output across the weather conditions encountered in full-time off-grid residential applications.
Q: How does the SGM-1320M compare to a small off grid solar system? A small off grid solar system typically covers cabins sheds and RV applications — the SGM-1320M at 13KW dual-inverter output addresses full-sized residential off-grid applications with simultaneous high-demand load capacity that smaller systems cannot match.
Q: Can the SGM-1320M be expanded? Yes — the SGM-1320M supports up to 6 identical inverters in parallel — in single-phase split-phase or three-phase arrangements — enabling additional solar panels and batteries to be added as energy requirements grow without replacing the existing system.
