FoxESS P3-PRO-25.0 Hybrid Inverter 25 kW Three-Phase
The FoxESS P3-PRO-25.0 is a 25 kW three-phase hybrid inverter from the P3 PRO series, dedicated to commercial and industrial photovoltaic systems with high-voltage storage (150-850 V). The distinguishing feature of the P3 PRO series is its high PV oversizing: it accepts up to 50000 Wp of modules, about 200% of the rated AC power, on 2 MPPT trackers with a 270-790 V range.
The maximum apparent power reaches 30000 VA and the EPS output guarantees up to 25000 VA during a grid outage, with a peak of 27500 VA for 60 seconds. The battery charge and discharge current reaches 50+50 A on two independent inputs. Maximum efficiency is 97.10% (European 96.60%), the protection rating is IP65 with intelligent fan cooling, and AFCI arc-fault protection is built in. Communication includes Ethernet, Wi-Fi, RS485, CAN for the BMS, USB, DRM and SG Ready.
