FAQ

What is the difference between Primo, Symo and GEN24?

Primo = single-phase on-grid (3-8 kW). Symo = three-phase on-grid (3-20 kW). GEN24 = new generation with integrated hybrid backup and Reserva battery support. For new systems we recommend the GEN24 (similar price, superior features).

How does Wattpilot solar charging work?

Wattpilot measures the surplus energy produced by the panels (after the house's consumption) and charges the car only with this surplus — continuously modulating the power between 1.4 and 11 kW (or 22 kW). Thus your car runs "for free" on solar energy.

How much does a Fronius Symo 10 kW inverter cost?

Fronius Symo Advanced 10.0-3 M costs approximately 9,500-12,000 RON. Symo GEN24 10.0 (hybrid) reaches 13,000-16,000 RON. With Smart Meter for prosumer, +800-1,200 RON.
