The HZEB-LCT-20 publishes about 180 kg and its own requirement to reinforce the wall, and the two figures that decide whether a particular wall can carry it are not on the page the installation was ordered from.
What the site walk has to establish
Five site conditions settle this installation before any bracket is discussed: the wall the unit will hang on, the route the unit takes to reach that wall, the space left for service, the electrical and data interface at that position, and the environmental envelope the location provides.
The unit itself is published at 750 by 1000 by 280 mm and about 180 kg, with a nominal voltage of 51.2 V, 400 Ah, a charge and discharge current of 200 A, a round-trip efficiency of at least 95 percent, an operating range of minus 20 to 55 degrees Celsius, and a protection rating of IP20 for indoor use. Its communication interface is published as CAN, RS485 and Ethernet.
Read as a site document, that list is the input to the walk rather than the answer, because four of the five site conditions are answered elsewhere, or nowhere.
Five questions and the published answers
Published figures are quoted from the product pages and the site survey checklist in this range, verified as of 2026-09. The right-hand column describes what the published pages do not contain rather than what no requirement exists for.
Two of those rows deserve a second look. The wall requirement is published on the model's own page as a condition attached to the weight, so it is part of the specification rather than advice, and the bracket it refers to is not published anywhere. The clearance figure is published in the site survey checklist rather than on the product pages, which is why a buyer reading only the product page concludes that no clearance is specified.
The route to the wall
About 180 kg through a doorway is a handling question that a floor plan answers faster than a datasheet. The unit's published footprint is the starting point: a face 750 mm wide and 1000 mm high has to pass the door frames, corridor turns and any stair on the route.
The published pages in this range state that units ship on a pallet in a reinforced wooden crate, and none of them publishes the crate dimensions or the crate weight. Those two figures, not the unit's own dimensions, are what the access route has to be checked against, and they belong in the quotation stage rather than on the delivery day.
Where the published answers conflict
Weight is the figure the wall design follows, and the published sources do not agree on it for every model in the family.
The product pages in this range publish the wall-mounted units at about 55 kg, about 95 kg, about 145 kg and about 180 kg as the capacities rise. A published article on the same site describes a wall-mounted HZEB-LCT-10 as weighing about 60 kg. The same model, two published figures, and about 35 kg between them, which is a scope gap rather than a rounding difference. For a bracket designed to a stated load, that gap separates a compliant installation from an under-designed one. Ruibit states the weight and the reinforcement requirement on the model page and leaves the bracket itself to the order, so the fixing design is the buyer's scope by default.
The clearance question has the same shape in reverse. The product pages publish none, the survey checklist publishes 50 cm above and below, and the two statements do not contradict each other so much as answer different questions. A clearance quoted for cable access and service is a working-space figure, not a statement about thermal or fire separation, which no page in this range publishes for this model. The two statements are not on the same basis either, because one describes working space and the other would describe separation.
Can it be done
The answer is conditional, and the conditions concern the wall rather than the unit.
If the wall is masonry, or the unit can be fixed through the finish to structure with a backing designed for the stated load, and the access route takes a pallet of this size, the installation proceeds, because the published requirement is reinforcement rather than a different product.
If the wall is a lightweight partition with no structure within reach of a fixing, or the only route to the chosen position passes a turn the crate cannot make, the answer is no for this position rather than no for this model, and the alternatives are a different wall, a floor-standing format, or a smaller unit in the family.
If the weight the backing is designed for cannot be established in writing, the answer is not yet, because every other decision follows that number.
What belongs in the order documents
Three items belong in writing before the order. Ask for the design load per fixing and the bracket's fixing pattern, since the published requirement names a heavy-duty steel bracket without publishing it. Ask for the crate dimensions and weight, because those decide whether the unit reaches the wall. Ask which clearances apply at the intended position and on what basis, since the only published figure in this range is a service-access dimension from the survey checklist.
Two items cannot be corrected after delivery. The anchors and the backing are permanent once the unit is on the wall, and the position itself is fixed at approval, because the grid registration follows the point of connection rather than moving with the unit.
At handover, record the wall build-up and the reinforcement design, the fixing type and its design load, the clearance left for service, and the access route used. Those four lines are what a later service visit, an expansion on the same wall, or a warranty question about the mounting will be judged against, and none appears on the page the unit was ordered from.
FAQs
1. What does the HZEB-LCT-20 require for wall mounting?
Its own page states that about 180 kg requires reinforced wall mounting with a heavy-duty steel bracket. The reference to a heavy-duty steel bracket is a published condition attached to the weight rather than a recommendation, but the bracket itself, its fixing pattern and the design load per fixing are not published.
2. How much space does it need for service?
The product pages publish no clearance figure for this model. A published site survey checklist states 50 cm above and below for cable access and service, and that is a working-space dimension rather than a statement about thermal or fire separation, which no page in this range publishes.
3. What has to be checked before the unit reaches the wall?
The route as well as the wall. The unit is published at 750 by 1000 by 280 mm and about 180 kg, and the pages in this range state that units ship on a pallet in a reinforced wooden crate without publishing the crate dimensions or the crate weight, so the access route cannot be checked from the published data alone.
4. Do the published weights agree?
Not for every model. The product pages publish the wall-mounted capacities at about 55 kg, about 95 kg, about 145 kg and about 180 kg, while a published article on the same site describes a wall-mounted HZEB-LCT-10 as weighing about 60 kg. About 35 kg separates the two figures for the same model.
5. What should be confirmed before ordering?
The design load per fixing and the bracket's fixing pattern, the crate dimensions and weight, and which clearances apply at the intended position and on what basis. The anchors, the backing and the mounting position are permanent after delivery.
