Description

The Fox ESS H3 Plus 100kW Three-Phase Hybrid Inverter is a high-capacity energy management solution designed for commercial solar and battery storage systems. It converts DC electricity generated by solar panels into usable three-phase AC power while managing the charging and discharging of compatible high-voltage LFP batteries. With a nominal AC output of 100kW and support for solar arrays up to 200kW, the inverter provides the capacity required for larger commercial properties and high-demand applications.

Eight independent MPPT trackers, each supporting two solar strings, allow the inverter to manage up to 16 strings across a large PV array. This provides greater flexibility when designing systems with different panel orientations, roof areas or levels of sunlight. A maximum conversion efficiency of 98.5% and European efficiency of 98.1% help minimise energy losses and maximise the amount of generated solar electricity available to the system.

The H3 Plus supports 100% unbalanced three-phase output, allowing power to be distributed according to the demand on each phase. This makes it suitable for commercial properties where electrical demand may vary significantly across the three phases.

When installed with compatible batteries and a correctly configured backup system, the EPS output can provide up to 110kVA during a grid failure. It can also deliver a peak output of 155kVA for up to 10 seconds, helping accommodate the temporary start-up demand of suitable commercial equipment. Switching to backup power takes less than 10 milliseconds, while whole-system and partial backup configurations allow installers to determine which loads remain powered during an outage.

What’s In The Box: Fox ESS H3 Plus 100kW inverter, left & right hanging plates, hanging plate connection bar, 4x screw-in handles, mounting bolts, nuts & screws, 32x DC connectors, 32x DC pin plugs, 2x ground terminals, 2x internal hexagon wrenches, 3x cable gland plates, load connection box, grid connection box, generator connection box, 3x communication connectors, DC connector removal tool, electricity meter, 3x CTs, antenna & quick installation guide.
