5KW Off Grid Solar Charge Inverter

5KW off-grid solar charge inverter combines a high-efficiency inverter and MPPT charge controller in one device, making it ideal for medium-sized off-grid setups like rural homes, cabins, and small farms. It maximizes solar energy harvest, integrates seamlessly with batteries, supports generator backup, and ensures stable power for daily essentials—all in a compact, easy-to-install design that simplifies off-grid living.

Products Description

5KW Off Grid Inverter

All-in-One Design: Combines a 5KW pure sine wave inverter and MPPT charge controller, eliminating the need for separate components. Streamlines system setup and reduces wiring complexity, perfect for DIY enthusiasts or small-scale installations.

5KW Power Output: Delivers 5KW continuous AC power (surge capacity up to 10KW for 5 seconds) to handle moderate loads-small air conditioners, refrigerators, washing machines, and home offices. Optimized for 220V/240V single-phase systems (50/60Hz), matching standard off-grid wiring.

High-Efficiency MPPT Charging: Single MPPT tracker (max DC input voltage 500V) with 99.0% efficiency, optimizing power from 10-12 x 400W solar panels. Adapts to low light, partial shading, or variable weather, boosting daily solar harvest by 28% compared to PWM controllers.

Battery Compatibility: Works with 24V/48V lithium-ion (LiFePO4) and lead-acid batteries (deep-cycle), supporting up to 30kWh storage via parallel connections. Intelligent BMS (Battery Management System) prevents overcharging, deep discharge, and cell imbalance, extending battery life by 30% in off-grid cycles.

Generator Backup Integration: Built-in generator input (compatible with 5-7KW generators) for extended cloudy periods. Auto-starts generators when battery SOC drops below 20% and stops at 80% charge to minimize fuel use. Manual mode allows user-controlled charging for flexibility.

Off-Grid Reliability: Designed for complete grid independence-no grid-tie functionality, ensuring stable power in remote locations (e.g., forest cabins, mountain retreats, rural homesteads). Maintains consistent voltage (±2%) for sensitive electronics (laptops, TVs) even with fluctuating loads.
