Sunboost 8.2KW 10.2Kw Hybrid Solar Inverter ON/OFF Grid Solar Power Inverter 220V 230V 240V 8KW 10kw Hybirid Solar Inverter for Home Use

This advanced hybrid inverter delivers a utility-grade pure sine wave AC output with exceptionally low total harmonic distortion (THD), ensuring safe and reliable operation for all sensitive electronics, from medical equipment to variable-speed motors. It features intelligent, seamless transition between on-grid and off-grid modes. In grid-tied mode, it prioritizes solar energy for self-consumption and can feed excess power back to the grid. During a grid outage, it automatically and instantaneously switches to off-grid mode, using solar and battery power to maintain an uninterrupted electricity supply for critical loads.

Equipped with a high-performance 160A MPPT solar charge controller, this inverter is engineered to support large-scale photovoltaic arrays up to 10.2KW. The controller utilizes advanced Maximum Power Point Tracking (MPPT) technology with a tracking efficiency of up to 99.9%, ensuring optimal energy harvest even under suboptimal conditions such as partial shading or fluctuating irradiance. Its high current capacity enables rapid battery charging, reducing downtime and enhancing system reliability for applications with substantial energy demands. Compatible with diverse battery chemistries (e.g., lead-acid, lithium-ion), the controller features adaptive multi-stage charging profiles (bulk, absorption, float) and temperature compensation to prevent overcharging or undercharging. This design maximizes battery cycle life while maintaining operational safety and efficiency in off-grid or hybrid solar systems.

The inverter boasts a wide Maximum Power Point Tracking (MPPT) voltage range of 90 to 500 VDC. This high voltage capability allows for the design of longer solar panel strings, significantly reducing balance-of-system costs by minimizing the number of combiners and the cross-sectional area of DC cabling. The broad operating window also ensures high efficiency across various weather conditions, enabling earlier system startup in the morning and later shutdown in the evening, thereby maximizing daily energy harvest.

This system is equipped with dual independent AC outputs, allowing users to manage loads with different priorities (e.g., essential vs. non-essential circuits). Concurrently, the dual MPPT inputs enable the connection of two separate photovoltaic arrays with different orientations, tilts, or module types. This architecture mitigates power loss caused by partial shading or mismatched panels, ensuring that each array operates at its own maximum power point for optimal overall energy yield.

An intelligent, multi-stage adaptive charging algorithm is employed to optimize battery health and longevity. The system offers customizable charging profiles for various battery chemistries (Lead-acid, LiFePO4, etc.), featuring precise control over bulk, absorption, and float stages. It includes temperature-compensated charging and can be configured for periodic equalization (for lead-acid), actively preventing conditions like sulfation and stratification to significantly extend the battery's service life.

Engineered with a high-efficiency, low-frequency transformer topology and optimized standby circuitry, this inverter exhibits remarkably low no-load power consumption. Its no-load loss is substantially lower than that of comparable high-frequency inverters, minimizing parasitic drain on the battery bank. This characteristic is critical for enhancing the overall autonomy and energy efficiency of off-grid and backup power systems, preserving valuable battery energy for when it is truly needed.
