The SoleHoyo QB-Hi series is a high-capacity off-grid solar inverter engineered for the global mid-to-large scale residential and small industrial power markets. Available in Hi-5KW, Hi-7KW, and Hi-11KW variants, it combines ultra-wide voltage adaptability, robust overload capacity, and intelligent monitoring capabilities, making it the ideal solution for high-power off-grid electrification, home energy systems, and small commercial applications across Southeast Asia, Africa, and beyond.
Key Advantages
Ultra-Wide Voltage Adaptability: Engineered for exceptional flexibility, it supports 250VDC low-voltage startup and an ultra-wide PV input operation range of 250–400VDC. With an MPPT working voltage window of 160VDC–390VDC, it maximizes energy harvesting efficiency across diverse solar array configurations and fluctuating irradiance conditions.
Robust Power Delivery: Delivers a stable 220-240VAC pure sine wave output with a maximum efficiency of 99%, ensuring safe and reliable operation for all household and light industrial appliances. It features a 1.2-times sustained overload capacity, easily handling peak power demands from heavy-duty equipment and load fluctuations.
Comprehensive Safety & Durability: Certified with CE compliance, it integrates multiple safety protections including DC reverse polarity protection, built-in DC SPD (Surge Protection Device) for lightning defense, and IP21 enclosure protection against dust and splashing water. The full-spectrum protection system (AC short circuit, overload, over-temperature, leakage current) ensures long-term reliability in harsh environments.
Intelligent Operation & Monitoring: Equipped with a user-friendly LCD interface for real-time data monitoring and parameter adjustment. It supports adjustable output frequency (50Hz/60Hz), enabling seamless adaptation to regional power standards across global markets, simplifying system deployment and operation.
