FAQ

Which hybrid inverters is this backup panel compatible with?

It has pre-wired terminals for quick connection to three-phase hybrid inverters with an EPS output of up to 40 kW. Check with Bilotex to confirm your specific inverter model.

Does the panel switch to the battery by itself in a blackout?

Yes. It comes with an Auto Transfer Switch (ATS) – 2P/4P 40-63-100Amps fitted: when the grid drops it moves the critical-load line to the inverter's EPS output, and back to the grid when power returns — no manual switching.

What is the maximum power this panel can handle?

It is rated for systems up to 40 kW, three-phase at 400 V. The main breaker is 63 A 4P.

What protective devices are included as standard?

A 63 A 4P MCB, a 30 mA Type A RCD and a Type II AC surge protection device (SPD), protecting the critical-load line against overcurrent, earth leakage and voltage transients.

Which loads can I connect to the backup line?

The critical loads you want to keep running during a blackout — lighting, fridge, router, water pump, alarm — as long as their total stays within 40 kW and your inverter's EPS output.

What is the IP rating?

The enclosure is IP54, suitable for technical rooms, garages or sheltered outdoor locations.

Does it need a qualified electrician?

Yes, it must be installed by a certified electrician under the applicable low-voltage regulations. Bilotex installs it together with the inverter and battery.
