Technical FAQs 3

How many wires does a 3 phase inverter use?

Split-phase 12 kW inverters typically use 2–3 wires (L1, L2, N) with 2–3‑pole breakers, while three-phase inverters usually use 4 wires, require balanced loads, and are often connected via four-pole breakers. What are the key specifications I should compare for a three phase inverter?

What is the difference between a split-phase and a three-phase inverter?

Split-phase inverters can connect to single-phase or split-phase grid power, whereas most three-phase inverters require a three-phase input. Split-phase 12 kW inverters typically use 2–3 wires (L1, L2, N) with 2–3‑pole breakers, while three-phase inverters usually use 4 wires, require balanced loads, and are often connected via four-pole breakers.

What voltage should a solar inverter be?

When purchasing a three-phase inverter, ensure the AC voltage range matches local standards (380 V/400 V/415 V). Our 12 kW inverter features a configurable 350–415 V range, suitable for most regions. What is the correct order to connect my solar system?
