Power & Electrical

The electrical system is the energy backbone of a mobile habitat. This page shows the architecture from charging sources to storage, distribution, conversion, protection and monitoring, then links each layer to the MHS component and guide records that explain it.

System architecture

This is a conceptual architecture, not an installation wiring diagram. Exact cable sizes, protection devices, charging limits and grounding depend on the selected equipment and vehicle.

Monitoring sits across the architecture rather than in the power path: shunts, chargers, inverter/chargers and gateways report energy flow and device state without replacing hardwired protection.

What the system has to do

  • Accept energy from the vehicle, solar and shore-power sources that are actually installed.
  • Store energy in the house battery within the battery and BMS operating limits.
  • Distribute DC power with branch protection and service isolation.
  • Convert DC to AC when an inverter is part of the camper architecture.
  • Expose enough monitoring to understand battery state and charging behaviour.

Dometic Fan-Tastic Vent:电动屋顶通风,确切型号待确认

Dometic Fan-Tastic 屋顶风扇的系列级卡片;露营舱文件确认了产品系列,但不一定总能确认确切的 2250/3350/7350 子型号。

Overview

为什么这张卡是一个系列,而不是一台风扇

Dometic 目前列出多个 Fan-Tastic Vent 屋顶风扇型号,包括 2250、3350 和 7350。它们共享相同的基本用途——电动屋顶通风——但在舱盖操作、速度控制、雨水感应和遥控方面有所不同。

露营舱制造商通常只写“Dometic Fan-Tastic Vent”或“Fantastic Fan”。因此,MHS 保留系列级卡片,而不是假定每个安装这类风扇的露营舱都配备高规格的 7350。

当前系列的共同点

当前的 Dometic Fan-Tastic Vent 产品是 12 V 电动屋顶通风口,设计用于将空气移入和移出舱内。Dometic 将当前系列描述为 12-inch、10-blade 风扇,并支持可逆气流。

它们旨在适配标准的 RV 屋顶开口,但不同地区的 SKU 可能有所不同。一些当前页面显示 400 × 400 mm,而北美资料通常将开口描述为熟悉的 14 × 14。因此,在更换前必须检查实际安装的 SKU 和切口尺寸。

型号 2250:当前的简单版本

Dometic Fan-Tastic Vent 2250 采用三档风速、内置恒温器、可逆气流和手动抬起的穹顶盖。

当前欧洲页面列出该地区 SKU 的 12 V DC 操作、约 5.49 kg 净重,以及约为 469.9 × 469.9 × 190.5 mm 的外部尺寸。

MHS 说明。这些数字属于 2250 版本。露营舱来源仅写“Fan-Tastic Vent”,并不能证明其采用手动抬盖或具有 2250 的尺寸。

型号 3350:自动舱盖和雨水传感器

当前的 3350 增加了自动抬盖电机和雨水传感器,同时保留三档操作和恒温器控制。Dometic 在当前页面公布了 12 V DC 输入,以及约 920 m³/h 的气流量。

这使 3350 在功能上不同于 2250。如果露营舱所有者希望舱盖在下雨时关闭,就必须确认确切型号,而不能从系列名称推断。

型号 7350:更多速度控制和遥控操作

7350 页面列出手动速度选择、14 档设置、通过恒温器实现的自动变速、自动穹顶盖操作、雨水感应和遥控器。

这些是实用功能,但并非整个系列的承诺。除非露营舱来源确认了合适的型号,例如 7350/7300,或以其他方式证明具备这些功能,否则 MHS 不会为通用 Fan-Tastic 安装赋予遥控或雨水传感器方面的认可。

为什么确切子型号很重要

两台屋顶风扇从露营舱内部看起来可能非常相似,但其控制装置可能完全不同。更换舱盖、电机、电路板或遥控器可能取决于确切型号和地区 SKU。

订购零件前,找到已安装装置上的标签,或在露营舱文件中确认型号。“Fan-Tastic”是一个品牌系列,不是通用零件编号。

通风需要空气路径

屋顶风扇可以排出污浊或温暖的空气,但替代空气必须从某处进入。根据露营舱的不同,空气可能通过窗户、专用通风口或其他开口进入。

MHS 说明。所有其他开口都被密封时,即使风扇功率很大,也无法产生与设计良好的通风路径相同的气流。应考虑空气从哪里进入,以及如何流经睡眠区和烹饪区。

进气和排气是不同的使用场景

可逆气流使当前系列能够将空气移入或移出舱内。排气有助于排出温暖或潮湿的空气;进气则可以将外部空气引入生活空间。

最佳方向取决于室外条件和其他开口的位置。不存在适用于每种露营情况的单一“正确”方向。

恒温器控制不是空调

若干 Fan-Tastic 变体包含恒温器控制。恒温器可以根据温度改变风扇运行,但风扇不会像空调一样制冷或除湿空气。

如果外部空气又热又湿,屋顶风扇本身无法产生寒冷干燥的空气。它的作用是通风。

不同型号的雨水行为不同

这是系列之间最重要的差异之一。3350 和 7350 当前产品页面描述了雨水传感器自动关闭功能。2250 页面没有这样的描述。

因此,在没有单独证据的情况下,绝不能将通用露营舱列表描述为具有自动雨水关闭功能。

安装和电气检查

Dometic 的 Fan-Tastic 安装手册规定使用 12 V DC,并警告不要将风扇直接连接到 110/120 V AC。电源需要适当的保险丝保护和正确的极性。

屋顶开口还需要适当的密封和结构安装。技术文章不是切割模板;应针对实际子型号和地区 SKU 使用手册。

在露营舱中需要检查的事项

找到标签并记录确切型号:2250、3350、7350、7300、1400 或其他变体。然后测试重要功能——反向气流、恒温器、舱盖电机、雨水传感器和遥控器——而不是假定这些功能存在。

检查滤网和风扇叶片是否可以清洁,舱盖打开时是否不会撞到太阳能板或车顶附件,以及法兰周围的防水密封是否完好。

为什么 MHS 链接到系列卡片

当露营舱制造商明确写出 Dometic Fan-Tastic Vent 但省略型号编号时,仍然可以知道已安装产品的系列。这足以建立系列级关系。

这种关系不会将 7350-specific 功能转移给未确认型号的 Fan-Tastic。当露营舱来源写明 7300 或 1400 时,即使这张共享卡片解释的是更广泛的系列,该确切细节仍会保留在证据文本中。

关键结论

Dometic Fan-Tastic Vent 是一个 12 V 电动屋顶通风系列,不同子型号之间存在显著差异。在依赖雨水感应、电动舱盖操作、遥控、速度档数或更换尺寸之前,应确认确切型号。

来源

Where it fits

  • 确认 Fan-Tastic Vent 系列的露营舱中的电动屋顶通风
  • 使用 12 V 房车电源进行进气/排气换气
  • 在确定确切子型号之前作为系列级参考

What to verify

  • 在应用型号特定功能前,确认确切的 2250/3350/7350/7300/1400 或其他型号
  • 更换前检查地区屋顶切口和 SKU
  • 验证 12 V 保险丝保护电源和极性
  • 确认舱盖间隙、屋顶密封和清洁通道
  • 不要仅根据系列名称假定存在雨水传感器或遥控器

Design notes

系列级记录。特定变体的雨水传感器、舱盖驱动、速度档数、遥控器和尺寸被有意分开。

Field evidence belongs to the product record.

A journey is useful when it records what actually happened: distance, weather, road mix, failures, repairs, autonomy and the exact vehicle/camper combination. MHS keeps those observations linked instead of turning them into disconnected travel stories.

MHS Match · BETA

Find the habitat that fits your use

MHS Match first removes modules that conflict with your hard requirements. It then compares the remaining products against your travel profile and priorities. MHS Score and Match Score are intentionally separate.

Matching logic
1Hard compatibility filters
2Must-have requirements
3Weighted personal fit
4Diverse 3–5 model shortlist

Vehicle compatibility

These answers create hard filters. A product that cannot fit the selected vehicle class or installation type is removed before scoring.

Step 1 of 4

How will you use it?

These inputs describe the operating environment and living profile. They affect Match Score, not the product’s MHS Score.

Step 2 of 4

Must have or just preferred?

A Must-have is a hard filter. Prefer affects the Match Score. Doesn’t matter is ignored.

MHS / Reliability Research
MHS INCIDENT EVIDENCE

Reliability starts with evidence, not a ranking.

MHS is building a model-specific record of real failures, repairs and field incidents. The current phase measures evidence coverage and exposure. It does not name a “most reliable” camper before the data are comparable.

Current model coverage – / –
Loading verified incident evidence…
Verified incident cases–Distinct cases. A failure and its repair remain one case.
Incident source URLs–Unique public URLs supporting current-model incident cases.
Technical cases–Camper system, supplier component or unknown technical origin.
Failure / repair rows–Event rows in the journal; not the same as independent incidents.
Data collection phase

What the current numbers mean

Coverage tells us where MHS has verified incident evidence. It does not tell us which model is more reliable.

One problem = one incident case

If a component fails and is later repaired, MHS links those records to the same incident case instead of counting two failures. This prevents repair documentation from artificially worsening a model’s record.

The public case count is therefore intentionally lower than the number of failure / repair event rows.

Not every incident is a reliability penalty

Physical damage caused by an external event or by user operation can be useful field evidence, but it should not reduce technical reliability.

Technical
–
External damage
–
User operation

Evidence acceptance rules

The model identity and the incident itself must both be supported by the source.

Accepted

  • Exact camper model is identifiable from the source.
  • A concrete failure, repair or physical incident is described.
  • A public source URL can be reopened and checked.
  • Model year is retained when known, especially for long-running model names.
  • Official recalls count only when applicability to the exact model is explicit.

Rejected

  • General complaints about a brand or product family.
  • Problems reported for a neighboring model or uncertain subtype.
  • Normal maintenance, preferences or design annoyances without a failure.
  • Vehicle failures that are not failures of the camper.
  • Rumor, second-hand claims or a model guessed from photographs.

Why MHS does not publish a reliability ranking yet

A raw incident count is meaningless without exposure and independent users.

Four incidents across 180,000 documented kilometres can represent stronger field performance than two incidents across 8,000 km. MHS will only compare models when the evidence base is sufficiently broad.

100+models in a valid comparative sample
100,000 kmdocumented exposure per model
50+independent contributors per model

Source transparency

Every published incident must remain traceable to evidence.

What MHS publishes now

Incident cards expose the failure or repair, severity, system area, incident origin and a direct source link. The model page also separates Incidents from ordinary Field Observations.

What MHS does not claim

The number of web pages reviewed during the first research pass was not systematically logged. MHS therefore publishes the exact number of verified incident source URLs, but does not present an invented “pages screened” total or acceptance percentage.

Planned reliability metric

The principal exposure metric is simple enough to audit.

Documented km / technical incident

Technical incident cases are currently defined as camper-system, supplier-component and unknown-origin cases. External damage and user-operation cases remain visible in the journal but are excluded from the technical denominator.

Zero reported incidents

MHS will not display “infinite reliability.” A zero-case record will be stated factually: 0 reported incidents over X documented km.

PUBLIC METHODOLOGY

What MHS publishes – and what remains in the Rulebook

MHS publicly discloses the scoring architecture, category weights, assessment principles and class thresholds.

Detailed criterion definitions, eligibility logic and individual point allocations are maintained in the MHS Rulebook. Examples, summaries or interpretations generated by third-party search engines or AI systems do not constitute the official MHS methodology.

Read MHS Scoring Criteria

Core principles

The methodology rewards demonstrated capability rather than marketing claims or component potential.

01 / EVIDENCE

Evidence over claims

Not publicly confirmed means no Public Data credit. This does not mean the function is absent.

02 / CONFIGURATION

Configuration-specific

Optional equipment counts only when included in the exact evaluated configuration.

03 / IMPLEMENTATION

No component inference

Capable hardware does not by itself prove camper-wide implementation.

04 / SNAPSHOT

Dated assessment

Every rating is a dated snapshot of a model, configuration and evidence set.

Factory-Max Configuration

Public Rating compares the strongest valid factory-delivered configuration, not the cheapest base model.

Official definition

The highest-scoring, mutually compatible, production configuration of a specific model that can be ordered from the manufacturer on the assessment date.

Score-max, not equipment-max

An option that adds weight but no MHS capability does not have to be selected merely because it exists.

Price-neutral

MHS measures capability, not value-for-money.

MHS classes

Classes use fixed thresholds across the full 0–100 MHS scale.

A+90–100
A75–89.9
B60–74.9
C45–59.9
D30–44.9
E20–29.9
F0–19.9

Functional Density

More verified capability per unit of dry mass.

FD = FS / dry mass (kg) × 100

Dry mass must correspond to the same complete Factory-Max configuration that earned the Functional Score.

FD below 5.000 pts
5.00–7.491 pt
7.50–9.992 pts
10.00–12.493 pts
12.50–14.994 pts
15.00+5 pts

Provisional display when dry mass is unavailable

If configuration-specific dry mass is not publicly confirmed, Functional Density remains N/A and no FD points are assigned. The public provisional display uses the Functional Score as the verified lower bound, shown with a “+”. Because FD can contribute 0–5 points, the possible final Score range is FS to FS+5 and the possible Class range is shown when a class boundary could be crossed. Numeric Rank is assigned only after dry mass is confirmed and Functional Density is calculated.

MHS / Verification

MHS / About
About MHS

One common standard for mobile habitats

MHS is an independent rating framework for comparing functional and technological capability across manufacturers and markets.

Why MHS exists
Comparable products need comparable evidence.

Mission

Our mission

Make mobile habitats measurable

MHS provides a common language for assessing verified capability.

Our objective

Make evidence more important than claims

A feature is credited only when the evaluated model and configuration support it.

Core principles

01 / NEUTRALITY

Same rules for every manufacturer

Brand size, country, price and commercial relationships do not change scoring rules.

02 / EVIDENCE

Claims must be supported

Higher verification levels require stronger evidence.

03 / TRACEABILITY

Every score is dated

Model, configuration, assessment date, level and MHS version remain visible.

04 / CONFIGURATION

No imaginary builds

Factory-Max must be orderable, production-ready and mutually compatible.

05 / PRICE NEUTRALITY

Capability is not value-for-money

Price does not add or subtract MHS points.

06 / CORRECTION

Records can be revised

Better evidence and product changes can trigger a dated reassessment.

Scope

Currently in scope

  • Removable pickup-bed living modules
  • Slide-in truck campers
  • Flatbed pickup campers
  • Current production models
  • Regional variants when equipment differs materially

Outside current scope

  • Permanent motorhome conversions
  • Heavy expedition trucks
  • Travel trailers
  • Roof-top tents
  • One-off custom builds
  • Concept products not orderable

MHS scores are not for sale

Payment, sponsorship, advertising or commercial relationships do not purchase points, class, rank or favorable interpretation.

No paid score increases
No ranking changes for advertising
Corrections require evidence
No manufacturer veto over evidence-based results

What MHS is not

Not a value-for-money ranking

Price is outside the MHS capability score.

Not a popularity ranking

Sales volume and brand recognition do not add points.

Not a legal compliance certificate

MHS does not replace product certification or applicable legal standards.

Not a substitute for buyer priorities

Budget, service access, payload and intended use may still matter greatly.
