ECO-WOR THY 10000W DC 48V UL1741 Inverter Charger
This 10,000-watt pure sine wave inverter is built for off-grid power. It combines inverter, charger, and two MPPT controllers, supporting up to 200A battery charging and parallel operation up to six units. It outputs 120/240V split-phase or 120V single-phase from a 48V system. Best for large off-grid cabins or workshops needing scalable energy harvest. Caution: Not grid-tie capable, so it cannot backfeed the utility.
- Best for high-capacity off-grid homes or workshops
- Better for systems needing dual MPPT with high charging current
- Avoid if you require grid backfeed or grid-tied operation
ECO-WORTHY Powermega 48V LiFePO4 Storage System

This 12kW unit expands off-grid capacity with 2 MPPT controllers and up to 220A charging. It supports parallel operation up to six units, enabling a scalable solution for larger homes and RV setups. It accepts high PV input (up to 500VDC) and works with diverse batteries, including LiFePO4 and lead-acid. Best for expanding power as needs grow; consider space and ventilation for heat management. Caution: Some configurations may require meticulous wiring for parallel banks.
- Best for future-proof, scalable power systems
- Better for multi-unit, high-demand installations
- Avoid if space and ventilation are severely limited
Buying Guide
What to consider when choosing a 10kW off-grid inverter
- System type: Pure sine wave vs. modified sine wave. Pure sine wave is essential for sensitive electronics and appliances.
- Voltage compatibility: Ensure 48V battery compatibility and desired output (120V single-phase, 240V split-phase).
- Parallel capability: If you anticipate future expansion, choose models that support multiple units in parallel (up to 6 units in many options).
- MPPT charging: Dual MPPT inputs can harvest more solar energy and handle larger PV arrays; check peak input power ratings.
- Battery compatibility: Verify compatibility with LiFePO4, lead-acid, or other chemistries you plan to use.
- Monitoring and connectivity: Built-in WiFi/Bluetooth and app compatibility help with remote monitoring and fault alerts.
- Protection features: Look for over-voltage, short-circuit, over-load protection, and temperature management for safe operation.
- Physical installation: Consider enclosure needs, ventilation, and indoor vs outdoor placement (IP rating).
