Short answer: the SR5000's home-grid feed and off-grid AC output are separate power paths, so their figures answer different questions. The current FlashFish Europe product page describes adjustable home-grid feed up to 800W. The authoritative product record and current page list 2400W rated off-grid AC output and 3600W maximum for 10 seconds. Do not add these figures or treat the 800W feed control as the system's off-grid load ceiling.
The 800W figure is a current public-page claim, not a field in the local product database. Before publication or installation, a human reviewer must confirm the exact regional manual, current configuration/firmware and the requirements that apply at the property.
One battery system, two different AC questions
A home-grid feed setting controls how much power the system contributes through its documented grid-connected path. Off-grid AC output describes how much a separate output path can supply to connected loads within its documented conditions. The same stored energy may be routed differently, but the ratings are not interchangeable.
| Question | Relevant SR5000 field | What it does not establish |
|---|---|---|
| How much controlled power may enter the home/grid path? | Public page: adjustable up to 800W | Off-grid load capacity or local permission |
| What is the rated separate off-grid output? | 2400W at 230V/50Hz | Automatic supply to every building circuit |
| What short maximum is listed? | 3600W for 10 seconds | Continuous operation or every motor start |
| How much energy is stored on the catalog rating? | 5120Wh | Fixed delivered duration or output power |
| How much PV input is listed? | Up to 2000W total | Actual solar yield in local conditions |
This path-based reading prevents a serious category error: 800W feed plus 2400W off-grid does not create a 3200W general output specification. It also prevents the reverse error of assuming an 800W feed control reduces the separate off-grid output to 800W.
Read continuous, short-duration and energy figures separately
The authoritative FlashFish product record lists SR5000 at 5120Wh, 2400W rated off-grid AC output at 230V/50Hz, and 3600W maximum for 10 seconds. It also lists two PV inputs up to 1000W each and a system mass of 59kg. These are product specifications, not an installation design.
The 3600W/10-second figure is a time-bounded maximum, not a new continuous rating. A motor or compressor can still depend on waveform, current shape, start duration and protection response. The 5120Wh capacity is an energy label; dividing it by load watts creates only an idealised before-loss boundary.
| Number | Correct planning use | Stop condition |
|---|---|---|
| Up to 800W grid feed | Current public-page control boundary | Exact regional manual/configuration or local route is unverified |
| 2400W rated off-grid | First combined-load gate on the separate output | Loads, startup or wiring path are unknown |
| 3600W for 10 seconds | Short-duration product boundary | A load needs longer or different start behaviour |
| 5120Wh | Energy-budget starting point | A fixed duration is being promised |
| 2000W PV input | Array/controller ceiling subject to input limits | Panel voltage/current or site design is unverified |
Why site and authority checks belong in the power calculation
The European Commission notes that solar energy in buildings may be consumed, stored, shared or exported, while detailed criteria and implementation vary. A product feature does not by itself establish the connection route for a country, distribution network, property or tenancy.
Before any grid-connected use, identify the exact regional SR5000 version, approved accessories, connection architecture, protective equipment, registration/notification path and network-operator constraints. If an installer or electrician is required, the product article cannot replace that review. Keep the feed setting within the documented and locally accepted configuration.
A four-step operating-path plan
- Draw the paths. Mark PV input, battery, controlled home/grid interface and separate off-grid loads.
- Assign each rating once. Put 800W only on the page-described feed path, 2400W on rated off-grid output and 3600W/10s on its time-bounded off-grid note.
- List loads and states. Record simultaneous watts, starting demand, priority loads, minimum reserve, low-solar state and battery-depleted state.
- Verify the handover. Document what happens during a grid event, fault, maintenance, firmware/configuration change or disconnected off-grid load.
This PATH worksheet makes uncertainties visible. If the proposed setup depends on a value absent from the exact manual or on an unconfirmed local connection rule, pause at that row instead of filling it with a generic answer.
Worked examples without installation claims
Midday self-consumption: PV may serve current household demand through the controlled feed path while surplus energy charges the battery, subject to the actual configuration. The feed control, not the 2400W off-grid rating, answers the maximum contribution question for that path.
Separate off-grid loads: devices connected to the documented off-grid output are assessed against 2400W continuous, with starting demand checked separately. This does not mean the system energises all circuits in the building.
Low-solar evening: stored energy may support the configured path until reserve or operating limits intervene. The 5120Wh label does not establish a fixed number of hours because load, conversion and control behaviour vary.
When SR5000 fits—and when it does not fit yet
SR5000 may fit a documented residential solar-storage plan that needs 5120Wh catalog capacity, up to 2000W PV input, a controlled home/grid contribution path and a separate off-grid output up to its rated boundary. Its 59kg product mass points to planned placement rather than casual portability.
It does not fit the evidence yet when the project assumes unrestricted export, automatic supply to every circuit, an unsupported connector, a predetermined financial result, a fixed duration, or acceptance by a local network without review. It also does not fit when the current 800W public-page value has not been reconciled with the exact regional manual and configuration.
Use the FlashFish Europe support centre to obtain the current SR2000/SR5000 manual, then have the installation and operating plan reviewed under the rules that apply at the property.
Human review checklist before use or publication
- Confirm the current page still states adjustable home-grid feed up to 800W.
- Confirm the exact regional manual/configuration supports the intended feed route and setting.
- Keep 2400W continuous and 3600W/10s tied only to the documented off-grid path.
- Verify PV voltage/current limits, connectors and array design.
- Record country, network operator, property and required professional/administrative steps.
- Define low-solar, battery-depleted, grid-event and fault behaviour.
Frequently asked questions
Why is the SR5000 grid-feed figure lower than its off-grid output?
They describe different power paths. Grid feed is the controlled AC contribution toward the home/grid interface, while off-grid output is the separate load-supply path.
Can I add 800W grid feed and 2400W off-grid output?
No. Do not add the ratings as one usable-output number. Each applies to a different operating path, configuration and set of constraints.
Does 2400W off-grid mean SR5000 can supply every household circuit?
No. The rating applies to the documented off-grid output path, not automatically to a building distribution board or every simultaneous load. Check the exact manual and installation design.
Is the 800W value confirmed in the local product database?
No. It is visible on the current public Europe product page but is not present in the authoritative local product record. It must remain a human-review item tied to the current regional page/manual/configuration.
Can this guide tell me whether grid feed is allowed at my address?
No. Connection, registration, equipment and export requirements vary by country, network operator, property and installation. Obtain the required local review before connection.
