Business continuity
For small businesses prioritising transaction systems, networking, refrigeration or orderly shutdown.
Sources and methodology
Source-based desk research and explicit calculations; no hands-on testing claimed. Missing values remain unknown. Installation compatibility needs a separate assessment.
Typical loads
Rank services by acceptable downtime. POS and networking may need seconds-level continuity while selected equipment can restart later. Validate actual daily schedules and refrigeration duty with measurements.
System architecture
Separate UPS-backed electronics from longer-duration battery or generator circuits. Document transfer, automatic restart, alarms and periodic test responsibilities. Avoid a single untested system feeding every business function.
Illustrative sizing
An illustrative 800 W essential load for 3 hours requires 2.4 kWh AC, about 3.26 kWh stored at 80% usable depth and 92% efficiency, plus any justified reserve. Refrigeration startup and UPS transfer must be assessed separately.
Solar and generator
Daytime solar may lower recharge energy from the grid but cannot guarantee outage coverage. Longer outages may justify generator integration only after fuel, access, noise and safe siting are considered.
Recommended equipment categories
Backup power
Keep essential loads operating with a defined autonomy and transfer requirement.
Inverters
Match continuous AC demand, starting surge and battery voltage.
Generators
Plan longer-duration supply around starting loads, fuel and safe outdoor placement.

Frequently asked questions
Is this a final installation recommendation?
No. Verify model manuals, actual loads, protection and site conditions with a qualified professional. Calculations and equipment classes are preliminary planning aids.
Where do I buy and who sets the price?
Purchase is with the external supplier, who controls price, delivery, inventory and returns. Confirm delivery to Romania before ordering. Commercial disclosure →
