Fox ESS products are engineered for reliability, scalability, and ease of use, offering customers flexible solutions that fit diverse energy needs while maximising self-consumption and cost savings.
The Fox ESS KH 8kW Single Phase Hybrid Inverter is a powerful energy management solution for larger residential solar and battery storage systems. It converts DC electricity generated by solar panels into usable AC power while directing surplus energy to a compatible Fox ESS high-voltage lithium-ion battery, ready to power the property when solar generation is insufficient or electricity is more expensive. With an 8,000VA nominal AC output and support for solar arrays up to 16,000Wp, it can help households increase their use of renewable electricity and reduce reliance on the grid.
Three independent MPPT trackers manage three solar panel strings separately, helping maintain efficient generation across panels with different orientations or levels of sunlight. The inverter supports up to 12,000W of PV input and has a wide 80V to 500V MPPT operating range. A maximum conversion efficiency of 97.8% helps minimise energy losses, while MPPT efficiency reaches 99.9%, PV-to-battery charging efficiency reaches 98.5% and battery-to-AC discharge efficiency reaches 97%.
Flexible operating modes allow the system to be configured around different household requirements. Self-use mode prioritises solar electricity for local loads before charging the battery and exporting surplus power. Feed-in priority mode supplies local loads before exporting electricity to the grid, while configurable charging times allow a compatible battery to be charged during selected periods.
The built-in backlit LCD provides convenient access to system information at the inverter. Its IP65-rated enclosure supports appropriately positioned indoor or outdoor installation, while natural cooling keeps typical operating noise below 30dB.
