Common questions
What Kyiv and Sumy customers ask
01Can backup power be installed in a Kyiv or Sumy apartment building?
Yes, provided the apartment panel is sound and there is ventilated space for the equipment. An inverter with a LiFePO₄ battery is quiet and emission-free, so it suits living spaces. We check refrigerator starting currents and wiring condition during the audit.
02How many hours will an apartment system run during an outage?
Autonomy is set by the average critical load and battery capacity, not the inverter rating. A worked example for a typical apartment is shown above; the final figure is confirmed from your appliance list.
03Does the condominium or building manager need to approve the system?
We work within the apartment panel without touching shared building networks. If the manager or condominium asks for documentation, we provide a single-line diagram and a scope description.
