2. What is the capacity and power rating of this three-phase battery?

It offers a usable capacity of 5.0 kWh. It incorporates 6 micro-inverters delivering a continuous power output of 3.84 kVA per phase and a peak power output of 7.68 kVA (for 3 seconds), suitable for three-phase households and small businesses.

3. Is the battery well suited to three-phase installations?

Yes, the IQ Battery 5P-3P-INT is a native three-phase system, ideal for three-phase domestic and commercial networks, ensuring optimal energy balance across all phases.

4. Can the battery be installed outdoors?

Yes, the IQ Battery 5P can be installed indoors or outdoors. It withstands temperatures from -20°C to 55°C, making it perfectly suited to the climates of Belgium, France, the French overseas departments and territories, and internationally.

5. What is the battery’s lifespan and warranty?

The battery uses LFP (lithium iron phosphate) chemistry, offering a long service life and maximum safety. It comes with a 15-year limited warranty, covering up to 6,000 charge cycles.

6. Does the IQ Battery 5P work with all Enphase solar systems?

It is fully compatible with Enphase IQ6, IQ7 and IQ8 micro-inverters, ensuring quick and easy integration with existing installations.

7. Can more batteries be added later?

Yes, the system is modular and scalable. You can start with a single 5 kWh battery and easily add further units as your needs grow.

8. How do you monitor and manage the battery?

The Enphase App allows you to monitor energy production, consumption and storage in real time, phase by phase, control your settings and carry out updates remotely.

9. Can the battery be used as a backup in the event of a power cut?

Yes, the IQ Battery 5P can provide backup power, ensuring that your essential appliances at home or in your business continue to operate.

10. Is this a cost-effective investment for a three-phase building?

Yes. By storing your surplus solar generation during the day to use in the evening and at night, you significantly reduce the amount of electricity you purchase from the public grid.

11. Why do Belgian customers have to pay the Bebat levy?

In Belgium, the law imposes a statutory environmental levy on all purchases of lithium batteries (€200.86 excluding VAT for this model). This amount will fund the safe recycling of end-of-life equipment via the Bebat organisation.
