SoleHoyo QB-42/62 Off-Grid Solar Inverter

The SoleHoyo QB-42/62 series is a high-power off-grid solar inverter engineered for the global residential and small commercial off-grid energy market. Boasting enhanced charging capacity, intelligent battery management, and robust environmental adaptability, it is the ideal solution for home energy systems, small business power supply, and remote area electrification across Southeast Asia, Africa, and beyond.

Key Advantages

Enhanced Charging Efficiency: Equipped with a built-in 100A MPPT solar charger (supporting up to 120A max PV charging) and a wide PV input voltage range of 120–450VDC, the inverter maximizes solar energy harvesting efficiency. The pure sine wave output with a power factor of 1 ensures zero reactive power loss, delivering clean and stable power for all household and commercial loads.
Intelligent Battery Protection: Integrated with a professional Battery Management System (BMS) and a dedicated battery equalization function, it optimizes battery performance, prevents overcharging/discharging, and significantly extends the lifecycle of lead-acid and lithium batteries. It also supports battery-free operation, providing flexible system configuration options.
Rugged Durability for Harsh Environments: Certified with CE compliance and built with a dedicated anti-dust kit, the inverter excels in high-temperature, high-humidity, and dusty conditions—perfect for the climatic characteristics of Southeast Asia and Africa. The RGB indicator lights and LCD display enable intuitive status monitoring and fault diagnosis.
Smart Remote Monitoring: Seamlessly compatible with Cube WIFI/GPRS modules, it connects to the Pvguarder APP and web platform for real-time remote monitoring, parameter adjustment, and fault alerts. This smart connectivity ensures convenient system management even for remote off-grid installations.
