Mini 3kW On-Grid Solar Inverter HBF3K
The Mini 3kW on-grid solar inverter, model HBF3K as listed, is the documented inverter model in this catalogue. It is a compact single-phase unit for connecting a residential or small commercial solar array to the grid, and the figures below are its own specification as listed in its manufacturer listing. Standard references in the listing are reproduced as listed; a standard name in a listing describes the framework the model was documented against and is not, by itself, a performance figure.

Read the table the way an installer would. The rated and maximum DC power figures frame the array sizes the unit is documented for; the MPP voltage range frames how the array must be strung; the protection rating frames where the unit can be mounted; and the efficiency figures describe conversion performance under the listing's stated measures. Your array design has to be checked against all of them together, not against the headline power figure alone.
Fit within a storage project
In a storage project this inverter is the on-grid conversion point for the solar array. Whether it suits your project depends on the array you have or plan, your grid connection and phase, and how storage is arranged alongside it. The inverter selection checklist works through those questions in order, and the inverter basics article explains the role of the unit in plain terms.
Terms
Before ordering, confirm the warranty term for this model in writing, together with the documents that cover it. Certificates available upon request. Before ordering, confirm minimum order quantity and lead time for your configuration.
String arrangement, in plain terms
A solar array is wired as one or more strings — panels in series — and each string presents the inverter with a combined voltage that moves with sunlight and temperature. The MPP voltage range in the specification is the window inside which the inverter can track the array's best working point. An array strung so its voltage sits inside that window across the year's conditions is a well-matched array; one that only enters the window at noon in summer is not, whatever the headline power figures say. This is why the selection conversation asks about string arrangement, and why an installer will want the panel figures and the layout before confirming that any given inverter suits a given roof.
Mounting and environment
The protection rating in the table is the figure that frames where this unit can be mounted, and the dimensions and weight frame the wall space and fixings it needs. Mounting still deserves a site sentence in the enquiry: whether the position is indoors or outdoors, what it is exposed to, and how the cables will run between the array, the unit and the distribution board. Compact units are often chosen for constrained spaces, and the constraint that matters is usually the cable route, not the box.
A complete answer about this model, for a real project, therefore has four parts: the specification table above, the string arrangement checked against the voltage window, the mounting position checked against the protection rating and dimensions, and the terms confirmed for the exact unit. An offer missing any of the four is not yet a complete answer, and the selection checklist will help you ask for the missing part.
