The Fronus ECO 4200 is a next-generation 4.2kW hybrid solar inverter from the premium Infineon series, designed to deliver maximum power with a minimal battery footprint. Unlike standard inverters, this powerful unit operates on a 24V battery system while supporting a massive 5200W PV array. With its upgraded MPPT chipset and a wide voltage range of 60V to 450V, it allows you to connect a high number of solar panels in series, ensuring your system generates maximum energy from dawn till dusk.

At Enon Traders, we highly recommend the Fronus ECO 4200 for smart homes due to its Two Load Output Power feature. It intelligently separates your heavy appliances (up to 4200W) from your critical backup loads (up to 1386W), automatically managing power during load shedding. Fully compatible with both Lead-Acid and Lithium-ion solar batteries, this unit is the perfect core for a robust home energy system. To ensure maximum safety and seamless power flow, we advise wiring your setup with our flexible wire 16mm square.
