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.

      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.

      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.

      MHS Methodology

      How mobile habitats are rated

      MHS evaluates factory-delivered functional and technological capability using a common evidence-based framework.

      Maximum MHS Score
      100
      Functional Score contributes up to 95 points and Functional Density contributes up to 5 additional points.

      Scoring architecture

      MHS is an absolute capability scale, not a percentile ranking.

      MHS = Functional Score + Functional Density points. The total maximum is 100 points.

      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 / 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.
