Esta es la versión mejorada del QB-Hi, con un diseño IGBT de plena potencia. Más detalles en la página del producto QB-Hi.
El QB-Hi 2 se presenta como un inversor solar off-grid IGBT de plena potencia en cuatro clases de potencia comerciales. Dado que el material suministrado no alinea cada columna de la tabla eléctrica de forma inequívoca con esas cuatro etiquetas, la corriente nominal exacta debe confirmarse antes de publicar una especificación por potencia.
La ficha suministrada posiciona al QB-Hi 2 para salida a plena potencia en cuatro clases de potencia comerciales.
La ficha comercial identifica tecnología de módulo IGBT para cargas CA exigentes.
El rango de trabajo publicado de 160-390V DC admite strings fotovoltaicos de alta tensión.
Los servicios de marca y configuración están disponibles sujetos a confirmación técnica y comercial.
The table separates verified published data from project-dependent choices. Match the product by electrical ratings and application conditions; do not select from the headline power value alone.

A dependable quotation requires the complete operating profile, not only the nominal power. IDEEI reviews voltage, current, source or motor data, duty, environment, required options and destination together so the final configuration, accessories, protection devices and commercial scope can be stated clearly.
Separate continuous load from startup surge loads such as pumps, compressors and motors. Check the PV string at the lowest expected temperature so open-circuit voltage remains below the product limit. Where a battery is used, match chemistry, nominal voltage, charge current and communication protocol. Source priority, transfer behavior, neutral arrangement and generator compatibility must be confirmed for the complete system.
Installation and commissioning must be completed by qualified electrical personnel. Isolate all energy sources before wiring, verify terminal functions against the current manual, provide protective devices and grounding, and apply the published derating guidance for altitude, temperature, enclosure and cable length. Product-page data supports preliminary selection and does not replace project engineering or local code compliance.
Battery-free operation is supported only where it is stated for the QB-Hi 2 Series and where the available PV or utility source can support the connected load. Confirm the intended operating mode before wiring.
Use the selected model’s permitted PV voltage window and maximum open-circuit voltage. Check cold-weather Voc, operating Vmp, current, total array power and local irradiance rather than selecting from inverter kW alone.
Supported AC input and source-priority modes depend on the selected series. The transfer arrangement, protection devices and neutral/earthing scheme must be confirmed for the installation.
Communication is model- and project-dependent. Confirm Wi-Fi, GPRS, RS232, RS485 and the required lithium-battery protocol before ordering.
Send the load list, surge loads, required output voltage and phase, PV module data, battery information, backup-source data, operating schedule, quantity and delivery country.
Send the required electrical and application data, quantity and destination. Our team will confirm the suitable model, options and quotation scope.
