FOX ESS P3-Pro-30.0 - three-phase hybrid inverter 30 kW.
Description FOX ESS P3-Pro-30.0
FOX ESS P3-Pro-30.0 is a three-phase hybrid inverter rated at 30 kW, the most powerful model in the Pro series. Three MPPT inputs, a high-voltage LiFePO₄ battery in the 150–800 V range, three CAN channels, generator support. Efficiency 97.8%, nominal output current 43.3 A per phase. Smart air cooling, IP65, 5-year warranty.
Thirty kilowatts — the simplified-connection limit
Many networks set the threshold for a simplified connection procedure precisely at thirty kilowatts for small business premises — without extended design documentation and lengthy coordination with the dispatch service.
The P3-Pro-30.0 hits that mark as efficiently as possible, delivering the greatest capacity obtainable without moving to a heavier technical-conditions procedure. For a shop, a small production facility or a hotel complex, this is often the decisive argument in favour of this rating rather than the next one up.
Three MPPT inputs allow the array to be spread across several independent groups — relevant for commercial sites with a complex roof or several buildings on one plot.

Same enclosure, the series' power ceiling
The dimensions and mass of the P3-Pro-30.0 fully match the smaller 20-kilowatt model — 560 × 600 × 225 millimetres and 52.5 kilograms. The manufacturer scales power within one platform, so the mounting point stays identical across the whole Pro series.
If you already have experience with the smaller model, or the project is designed for possible expansion, moving to the top version requires no revision of the mounting scheme.
Battery and generator for stable business operation
A 150–800 volt range and three independent CAN channels allow battery capacity to grow in stages in step with the business's real growth, without mixing stacks of different ages on one bus.
Generator support covers long outages without loss to commercial activity: the inverter starts the generator automatically according to charge level and stops it once the threshold is reached.
Control through FoxCloud
The app shows generation from each of the three MPPT inputs, battery state and current site consumption in real time. Modbus TCP and RTU allow the inverter to be integrated with the business's energy metering system and expansion to be planned on actual data.
Night monitoring keeps the link alive around the clock, so battery discharge during dark hours appears on the charts in the same detail as daytime generation — simplifying diagnostics and making deviations from the normal pattern easy to spot.
Thirty kilowatts is the maximum capacity within simplified connection for small business. Write to us about your site and critical load: we will check the technical conditions and calculate the battery configuration.
