Package the current Zorastra 1.792kWh LFP balcony solar storage system as a fast-moving European kit: Balkonkraftwerk Speicher positioning, solar input by day, evening household-load offset, clear appliance runtime answers and reseller-ready documentation.
The system is designed for balcony solar storage and evening-load offset. Whole-home UPS or air-conditioner backup requires a final configuration with a certified off-grid AC backup output.
Store balcony solar by day. Use it for evening essentials.
This keeps the message close to the real product. It connects to heatwaves, high evening tariffs and apartment use, while avoiding risky blackout claims.
Use a conservative 1.5kWh usable-energy basis after battery reserve, conversion losses and real-world operation. Actual runtime changes with appliance efficiency, ambient temperature, inverter setup and whether the product is operating grid-tied or through a backup output.
| Load | Typical power | Conservative runtime from ~1.5kWh | Practical note |
|---|---|---|---|
| Refrigerator | 40-80W average | 18-36 hours | Keep food storage covered through evening peaks; old or large fridges run shorter. |
| Efficient refrigerator | 25-45W average | 33-60 hours | Useful for modern apartment kitchens and summer self-use messaging. |
| WiFi router | 10-20W | 75-150 hours | Keep home internet offset or backed up if paired with a compatible AC output. |
| Fan | 30-60W | 25-50 hours | Simple heatwave comfort claim, low technical risk. |
| Small mobile air conditioner | 600-1000W | 1.5-2.5 hours energy equivalent | Can offset part of AC consumption while grid is available. Do not claim blackout AC backup without a suitable backup output and surge rating. |
| Laptop or light office setup | 45-80W | 18-33 hours | Remote-work continuity angle for apartment users. |
| EUR 0.25/kWh | ~EUR 0.38 per full cycle |
| EUR 0.30/kWh | ~EUR 0.45 per full cycle |
| EUR 0.40/kWh | ~EUR 0.60 per full cycle |
Typical use: shift up to about 1.5kWh of balcony solar energy into evening consumption. Actual savings depend on generation, household load and local tariff.

These answers use the same conservative 1.5kWh usable-energy basis as the runtime table. Actual runtime depends on appliance efficiency, operating conditions and the final system configuration.
A refrigerator averaging 40-80W can run for about 18-36 hours. A modern efficient refrigerator averaging 25-45W can run for about 33-60 hours. Large, old or frequently opened fridges run shorter.
A 10-20W WiFi router equals about 75-150 hours on a 1.5kWh usable-energy basis, if the setup includes a compatible AC output or operating mode for that load.
A 30-60W fan equals about 25-50 hours. This is the safest heatwave comfort message because fan startup demand is low compared with air-conditioning.
A 600-1000W mobile AC equals about 1.5-2.5 hours of energy use, but startup surge and output limits must be verified. Treat AC use as consumption offset rather than blackout backup unless the final configuration supports a backup output.
Use this claim: shift up to about 1.5kWh of balcony solar energy into evening use per full cycle. At EUR 0.25-0.40/kWh, that is about EUR 0.38-0.60 of electricity value per full cycle.
Source documents reference IEC 62619:2022, UN3480, UN38.3, IEC 62321 RoHS-related testing and DEKRA EMC attestation for the BDN micro-inverter family. Local grid registration still needs country checks.
The kit is positioned as plug-and-play balcony solar storage with MC4 PV input, micro-inverter and cable set. Buyers must still follow local balcony mounting, plug and grid-connection rules.
Only list an EU return or service address after the warehouse, distributor or service partner is confirmed. Before that, use distributor-backed warranty support and certificate-folder language.
For qualified distributor and project orders, Zorastra can coordinate supply through its German manufacturing and warehouse partner, supporting European delivery planning, documentation and reseller preparation.
The product is produced with Zorastra's German manufacturing partner. Zorastra handles product positioning, distributor communication and export coordination, while European partner production and testing support local supply capability.
The page uses only claims found in the provided product specification and certificate set. Final market registration, plug type and grid-code paperwork should be checked by country before public retail launch.
Available source documents reference IEC 62619:2022, UN3480 / UN38.3, IEC 62321 RoHS-related testing and DEKRA EMC attestation for the BDN micro-inverter family.

Zorastra works with a German manufacturing partner for balcony solar storage production, battery module testing and European distributor supply. For qualified orders, the product can be supplied directly from Europe, reducing long-distance shipping friction and giving resellers a clearer route for stock planning, documentation and after-sales coordination.
The partner facility supports battery cell sorting, module assembly, functional testing, inventory handling and palletized shipment preparation for European markets. Availability, exact lead time, service terms and country documentation are confirmed by quotation.
European partner production and testing support can be coordinated for qualified orders. Delivery scope, documentation and service arrangements are confirmed for each project.
We help qualified partners confirm the right configuration, prepare the applicable documentation and plan the order and service boundary for their market.
Confirm the kit configuration, plug type, certificate availability and user documentation for the destination market.
Use the runtime guidance to explain self-consumption and practical household loads within the confirmed system limits.
Discuss expected quantity, delivery terms, spare-parts needs and the local installation or service arrangement before order confirmation.
Send us your target country, plug type, expected quantity and channel. We will confirm the correct kit configuration, documentation package and shipment terms.
