Overview
The Fronius Wattpilot Home 22J earns its Editor’s Pick badge by doing something no other widely available charger manages quite as well: integrating seamlessly with any brand of solar inverter to provide genuine excess-solar EV charging.
Solar Integration
Three charging modes — Fast (grid draw allowed), Eco (solar-only), and Next Trip (charges to a set level) — cover every use case. Eco mode adjusts output in 1A increments to precisely track your solar surplus.
OCPP & Load Management
Full OCPP 1.6 compliance means the Wattpilot can be managed by home energy management systems and fleet management software. The built-in load management prevents your EV charging from tripping the main fuse.
Frequently Asked Questions
Does the Wattpilot work with non-Fronius solar? Yes — it uses a CT clamp to measure whole-home energy flow and works with any inverter brand.
What cable do I need? A standard IEC 62196 Type 2 to Type 2 cable (Mode 3), available from most EV accessory retailers.
