Common questions
What Kyiv and Sumy customers ask
01Will the system handle pump, boiler and gate starting currents?
Pump starting currents are several times the nominal figure, so the inverter is sized for the peak, not the average. We measure or estimate the starts during the audit and record them in the specification.
02The house has a three-phase supply — what changes?
We choose between a three-phase architecture and dedicated critical single-phase groups. The decision depends on pumps, the boiler and phase balance; both options appear in the proposal with their trade-offs.
03Can an existing generator be integrated?
Yes. A generator can charge the battery and feed backup circuits through automatic transfer. The grid / battery / generator priority is configured and tested at commissioning.
