5kW Off-Grid Solar Power System 580-740W LiFePO4 Battery for Home Storage ESS

The TIANON ENERGY ESS10 is a complete 5kW off-grid solar power system engineered for residential and home applications where grid connection is unavailable or unreliable. This all-in-one kit includes 580-740W bifacial half-cut monocrystalline PV modules, MPPT charge controller, LiFePO4 battery storage, DC cables (PV1-F 4mm²), and BIPV mounting hardware—everything needed from a single supplier for a turnkey off-grid installation. Each PV module measures 2279×1134×30mm and weighs 31kg, with a 43.03V / 13.96A MPP rating for high energy yield. The system delivers 230V/380V output at 50Hz/60Hz with 24-hour continuous operation capability. CE, IEC, MSDS, and UN38.3 certified for global compliance and safe international shipping.

• 580-740W bifacial half-cut monocrystalline modules - high-efficiency bifacial panels capturing light from both sides for up to 25% additional energy yield, with 43.03V / 13.96A MPP rating, 2279×1134×30mm dimensions, and 31kg lightweight aluminum frame for easy handling.
• 5kW off-grid power capacity - robust 5kW load power supporting full residential electrical demand including lighting, refrigeration, HVAC, water pumps, and kitchen appliances with reliable 24-hour continuous operation at 230V/380V output.
• LiFePO4 battery storage - safe, long-cycle Lithium Iron Phosphate chemistry with superior thermal stability and deep discharge capability, shipped with MSDS and UN38.3 certification in dangerous-goods-rated packaging for trouble-free export.
• MPPT charge controller - maximum power point tracking technology optimizes solar harvest throughout the day, adapting to changing irradiation and temperature conditions for maximum energy efficiency from the PV array.
• BIPV mounting system - building-integrated photovoltaic mounting option provides clean architectural integration, with support for additional roof mount and ground mount configurations to suit any installation site.
• Dual voltage/frequency output - flexible 230V/380V output at both 50Hz and 60Hz for compatibility with electrical standards worldwide, enabling deployment across diverse international markets.
• Comprehensive warranty coverage - 10-year cell warranty plus 25-year power performance warranty on the PV modules, backed by TIANON ENERGY direct factory support and global technical assistance.

• CE - European conformity for electrical safety and electromagnetic compatibility
• IEC - International Electrotechnical Commission standards compliance
• UN38.3 - passed all T1-T8 transport safety tests for sea and air freight
• MSDS - material safety data sheet available on request
• Dangerous Goods Packing Certificate - compliant packaging for lithium battery transport

• Remote residential homes and cabins with no grid access requiring complete energy independence
• Rural and agricultural properties needing reliable off-grid power for daily operations
• Island and coastal residences where grid connection is prohibitively expensive or unavailable
• Emergency backup power for homes in areas with frequent grid outages or natural disasters
• Eco-friendly sustainable living projects prioritizing renewable off-grid energy self-sufficiency

1. Is the system truly complete for off-grid installation? - Yes, the ESS10 kit includes PV modules, MPPT controller, LiFePO4 battery, DC cables, and BIPV mounting hardware. An inverter may be required depending on your AC load configuration—contact our team for guidance.
2. What is the expected daily energy generation? - With 580-740W bifacial panels, daily generation depends on installed capacity and local irradiation. A typical 5kW array can generate 20-30kWh per day in optimal sunlight conditions.
3. Can the system be expanded later? - Yes, the modular design supports adding more PV panels and battery capacity as your energy needs grow. Our engineering team can provide system expansion consultation.
4. What maintenance is required? - Minimal maintenance. PV panels require periodic cleaning. The LiFePO4 battery is maintenance-free. We recommend annual system inspection for connections and mounting integrity.
5. What certifications does the system hold? - CE, IEC, MSDS, UN38.3, and Dangerous Goods Packing Certificate for full international compliance and safe transport worldwide.
