Inverter – FoxESS – P3-12.0-SH – hybrid – HV
Product details
P3-S
P3-S is a series of Fox ESS three-phase hybrid inverters compatible with high-voltage LFP lithium-ion batteries. They enable the use of solar energy during the day and its storage for the night. Plug-and-play configuration and installation simplify commissioning, while FoxCloud V2.0 allows remote monitoring of device operation via a mobile app or website.
Key benefits of P3-S
- Nominal output power 5–15 kW and 2–3 independent MPPT circuits, depending on the model.
- Compatibility with LFP batteries with a voltage of 100–800 V and a maximum charging and discharging current of 50 A.
- EPS output with a switchover time of less than 20 ms and a maximum apparent power of 5000–15000 VA, depending on the model.
- Protection rating IP65 allowing outdoor use and wall mounting.
- Short-circuit, overcurrent and thermal protection and type II surge protection on the PV and AC sides.
- Standard 10-year warranty for the entire series.
Who is this a good choice for?
P3-S is an option for homeowners and businesses that want to use solar energy and store it in batteries for nighttime use. The power range allows users to choose a model that matches the required system capacity, while remote monitoring makes it easier to track system operation.
