Short answer: compare SR5000 proposals by what they prove and include, not by the lowest total alone. A useful quote identifies the responsible business, site assumptions, exact equipment and cable route, protective and grounding work, permissions, commissioning tests, handover documents and exclusions. If two quotes describe different work, their prices are not comparable.
Use QUOTE to normalise every proposal
- Q — Qualifications and permissions. Name the contracting business, responsible installer, insurance or registration evidence where applicable, and who checks landlord, building, municipal and network requirements.
- U — Unit and site scope. List the exact SR5000 variant, PV modules, mounting, cable lengths, connectors, monitoring setup, delivery, access equipment and any survey assumptions.
- O — Outputs and protections. Record the intended off-grid or other approved output path, earthing/grounding plan, isolation, protection, weather exposure, ventilation and cable protection.
- T — Testing and commissioning. Require named checks, configuration, monitoring demonstration, photos or readings, acceptance criteria and the person who signs them.
- E — Exclusions and handover. Make permits, structural work, wall penetrations, scaffold, disposal, remedial work, warranty contacts, manuals and as-built records explicit.
Quote comparison table
| Field | What a comparable quote should state | Stop and clarify when |
|---|---|---|
| Site and permissions | Address, ownership/tenancy, balcony or façade constraints, responsible checks and assumptions | The proposal says 'EU approved' without naming the local route |
| Equipment | Exact SR5000, panels, mounts, cables, connectors, monitoring and included accessories | Key components are 'or equivalent' without a defined performance and warranty basis |
| Placement | Measured location, load-bearing review where needed, weather exposure, drainage, access and required clearances | A generic product photo replaces a site plan |
| Electrical scope | Approved connection path, earthing/grounding, isolation, protection, cable route and responsibility boundaries | The buyer is expected to improvise connectors, protection or wiring |
| Commissioning | Tests, settings, monitoring setup, evidence and acceptance/sign-off owner | 'Turn on and check' is the only described handover |
| Price and exclusions | Total price, tax, payment stages, optional work, foreseeable extras and change-control method | A low headline excludes delivery, access, remedial work or commissioning |
| Aftercare | Manuals, as-built information, warranty contacts, fault route and maintenance responsibilities | The installer and product-support responsibilities are unclear |
SR5000 facts that should shape the scope
The authoritative FlashFish product record lists 5120Wh nominal capacity, 2400W rated off-grid AC output, two PV input channels rated up to 1000W each and 2000W total, an IP65 enclosure context and a listed mass of about 59kg. It also requires grounding and at least 150mm clearance at the top and rear. These fields help a buyer ask better questions; they do not decide where the unit may be placed or how it may be connected at a particular property.
Ask each bidder to identify which manual revision and regional configuration supports the proposed design. If the proposal depends on a value that is absent from the manual, request written manufacturer clarification rather than treating sales copy or connector fit as design evidence.
Make price genuinely comparable
Separate the base system, site work, permissions/notifications, access equipment, electrical protection, commissioning and optional extras. Then compare the same scope. A higher quote may include a survey, protected cable route and documented handover that a cheaper quote omits; a lower quote may still be better when its exclusions are deliberate and the buyer has assigned those tasks elsewhere.
Use payment stages tied to observable deliverables—such as survey completion, equipment identification and signed commissioning evidence—only after checking the proposed contract and local consumer rules. Do not accept forecast savings or payback as a substitute for scope.
Red flags worth resolving before signing
- One total price with no component, labour or exclusion schedule.
- No exact property, balcony, route or regional-product assumptions.
- 'Plug and play' used to bypass grounding, permission or connection questions.
- No named party responsible for landlord, association, municipal or network checks.
- No weather, ventilation, clearance, weight or cable-protection review.
- No commissioning record, monitoring handover or acceptance criteria.
- A guaranteed bill reduction, fixed payback or whole-home-backup claim without a site-specific evidence model.
- Pressure to pay before missing technical or contractual fields are supplied.
When SR5000 may fit—and when to pause
| A documented SR5000 proposal may fit | Pause the project |
|---|---|
| The site, placement, cable route, permissions and responsibilities are explicit | Building, tenancy, network or electrical permission remains unresolved |
| The quoted hardware and intended use stay inside current product documentation | The design relies on undocumented adapters, connection modes or output claims |
| Grounding, clearances, protection, commissioning and handover are included | Critical safety or testing work is left to an unqualified buyer |
| Price, exclusions and change control are transparent | The decision depends on guaranteed savings, payback or generic yield claims |

FAQ
Is SR5000 legal on every European balcony?
No EU-wide statement can approve every address. National, municipal, building, tenancy, electrical and network requirements can differ.
Should the cheapest installer quote win?
Only after scope is normalised. Compare the same equipment, site work, protections, permissions, commissioning and handover.
Does IP65 remove the need for a placement review?
No. An enclosure rating does not answer structural load, access, clearance, drainage, cable route, local rule or installation questions.
What commissioning evidence should I request?
Ask the responsible professional to define the checks, readings, settings, monitoring demonstration, photos or records and acceptance criteria appropriate to the local design.
Can an installer guarantee savings or payback?
Treat guarantees cautiously. Consumption, tariffs, solar input, control strategy, season and fees vary; demand a transparent site-specific method and assumptions.
Conclusion
The strongest quote is the one that makes responsibility visible. Apply QUOTE—Qualifications, Unit and site scope, Outputs and protections, Testing, Exclusions and handover—then compare like with like. Ask FlashFish Europe for the current SR5000 manual and pre-sale documents when a product field is missing, and use local professional and authority checks for the property-specific decision.
