$3,699.99 $2,699.99 Guardar 27%

⚪Complete 48V Solar Backup System: A ready-matched 48V off-grid solar kit built for essential home backup, cabins, farms, garages, workshops, and serious DIY energy storage projects. The system includes 8 × 200W solar panels, a 3600W all-in-one inverter charger, a 51.2V 100Ah 5.12kWh LiFePO4 server rack battery, and essential cable accessories.

⚪3600W All-in-One Inverter Charger: The included 48V inverter charger delivers up to 3600W of pure sine wave 120V AC output for essential home loads. It helps power refrigerators, lights, WiFi routers, fans, TVs, small appliances, tools, and sensitive electronics more smoothly during outages or off-grid use.

⚪5.12kWh LiFePO4 Energy Storage: The included 51.2V 100Ah LiFePO4 server rack battery stores 5.12kWh of backup energy for outages, nighttime use, cloudy days, and remote power needs. It provides a practical lithium energy reserve when solar input or grid power is unavailable.

⚪8 × 200W Solar Panels for 1600W Rated Solar Power: The kit includes eight 200W monocrystalline solar panels, providing up to 1600W total rated solar power under ideal sunlight conditions. This helps recharge the battery during the day and reduce dependence on grid power or generator charging.

⚪Power Your Essential Loads During Outages: Keep important 120V devices running when grid power is unavailable. This system is designed to support essential loads such as refrigerators, lights, WiFi routers, fans, TVs, small appliances, garage equipment, and basic tools.

⚪Built for Higher-Power 48V Solar Storage: Compared with small 12V starter kits, this 48V system is better suited for higher-power backup applications, cleaner system design, and more serious off-grid energy storage projects for homes, cabins, farms, garages, and workshops.

⚪Flexible Solar, Utility & Hybrid Charging: Choose the charging strategy that fits your setup. The system supports solar priority, utility priority, hybrid charging, and solar-only charging, making it suitable for home backup, off-grid use, and areas with unstable grid power.

⚪Smart Monitoring & System Control: The inverter includes an LCD display and supports WiFi/GPRS monitoring options, allowing users to check system status, input and output power, battery information, charging mode, and operating performance more easily.

⚪Battery & Inverter Protection Design: The LiFePO4 battery features a built-in BMS to help protect against overcharge, over-discharge, over-current, short circuit, and high/low temperature issues. Shunt trip protection and pre-charge circuit design help support safer battery-inverter connection and smoother system startup.

⚪5-Year Warranty & WEIZE Support: Backed by a 5-year limited warranty and WEIZE customer support, this kit is designed to help users build a home backup or off-grid power system with more confidence. Professional installation is recommended for AC wiring, grounding, breaker selection, and code-compliant setup.
