ECO-WORTHY Complete Off-Grid Solar Kit
The ECO-WORTHY Complete Off-Grid Solar Kit combines a 5000W pure off-grid inverter with a 10.24 kWh integrated battery bank and a full array of 24×195W bifacial panels. It supports single-phase 120V output or dual-unit 240V via parallel operation and can scale to 30 kW AC when multiple inverters are paralleled. The system includes CAN/RS485 communication, a 100A MPPT controller, and a Bluetooth/WiFi monitoring interface for real-time performance checks and optimization.
Key components include two 48V 100Ah LiFePO4 batteries with full-metal casings, a 100A BMS, and a 125A safety switch. Optional 3U cabinet enables space-saving installation. The kit is designed for home backup, off-grid living, and back-up resilience in power outages, offering robust energy independence and modular expandability.
ECO-WORTHY Home Power Station Backup Power (30kWh Capacity)
This Home Power Station integrates a 5 kW MPPT off-grid inverter with six LiFePO4 batteries, offering up to 30 kW parallel AC output when multiple inverters are combined. The system supports 120V operation and can scale up to 163.84 kWh of storage by paralleling up to 32 batteries. It is UL 1741 and UL 9540A certified, including CAN/RS485 communication and Bluetooth/Wi‑Fi monitoring for status checks and on-demand optimization.
Charging flexibility includes AC mains charging (up to 40A for full charge in about 15 hours) and PV charging (up to 100A with a full charge in about 6 hours). This makes it suitable for long-term home backup and multi-day outages while maintaining system safety with a full-metal shell and 100A BMS.
EF EcoFlow Delta Pro with Extra Battery
The Delta Pro is a portable, expandable power station designed for home backup and outdoor use. It starts with 7.2 kWh capacity and can be expanded to 14.4 kWh with an extra battery, delivering 3600W of continuous power (up to 4500W with X-Boost). Solar charging is supported, and the unit can be paired with multiple modules to reach 7,200W of total capacity in a multi-unit setup. The device emphasizes fast charging, silent operation, and flexible deployment for outages, camping, or emergencies.

The design supports safe integration with solar charging and grid interaction, making it suitable for mid-to-large residential backup deployments.
Buying Guide
- Storage capacity: Assess daily energy use and outage duration. Higher kWh ratings enable longer autonomy but require more space and higher upfront cost.
- Inverter rating: Match inverter wattage to essential loads. For larger homes, consider systems with 5 kW to 10 kW bases and potential parallel expansion for higher output.
- Expandability: Many systems allow parallel batteries or additional inverters. Plan future growth to avoid replacement costs later.
- Charging sources: Look for solar-only charging, grid charging, or hybrid charging. Faster charging reduces downtime between outages.
- Safety certifications: UL 1741, UL 1973, and UL 9540A indicate adherence to safety standards for batteries and inverters.
- Monitoring and control: Bluetooth, Wi-Fi, and app-based monitoring help track performance, state of charge, and health indicators in real time.
- Physical footprint and installation: Wall-mounted or floor-standing units vary in space requirements. Consider service access and ventilation.
- Maintenance and warranties: Verify BMS protections, cycle life expectations, and warranty terms for batteries and inverters.
- Grid interaction: If you plan to participate in demand response or solar credits, confirm compatibility with local utility programs and safety isolation features.
