myenergi Zappi Review

Is the myenergi Zappi worth it?

myenergi Zappi review: THE KEY FEATURE: automatically adjusts EV charging speed to match your surplus solar output. Zero grid draw. MODES: (1) ECO — charges from surplus solar only (may be slow but FREE). (2) ECO+ — charges from surplus + cheap overnight tariff. (3) FAST — charges at maximum speed from any source. SPEED: 7kW (single-phase) or 22kW (three-phase). PRICE: £800-£1,000 installed. HOW IT WORKS: a CT clamp measures your grid connection. When solar exceeds household demand, Zappi diverts the surplus to your car. As clouds pass, it adjusts in real-time — down to 1.4kW minimum. SAVINGS: £400-£600/yr on EV fuel costs (vs petrol). Free driving 8+ months of the year. VERDICT: the only EV charger purpose-built for solar. If you have solar + an EV, Zappi is essential.
