Your solar inverter must match your electricity connection. Most homes in India have a single-phase supply; larger homes, shops and factories often have three-phase. You can usually tell from your bill, your meter or your main switchboard.
Three ways to check
- Electricity bill: look for “phase”, “connection type” or “1-ph / 3-ph” near your sanctioned load.
- Meter: a three-phase meter is usually larger and shows readings for R, Y and B phases.
- Main switchboard: a three-phase supply has three live wires and usually a 4-pole main switch.
If you are unsure, ask an electrician; do not open the meter or switchboard yourself.
Which Tenzor inverter fits?
| Connection | Tenzor inverter | Range |
|---|---|---|
| Single-phase | Supernova 1-Phase (on-grid) | 1 to 6 kW |
| Single-phase, with backup | Hypernova (hybrid) | 3 to 6 kW |
| Three-phase | Supernova 3-Phase (on-grid) | 5 to 15 kW |
What if my sizes overlap?
At 5 to 6 kW, both single-phase and three-phase models exist. Choose by your connection, not by size. Your electricity company may also have rules on how much solar can be connected to each type of connection; your installer will check this.

Do I need to change to three-phase for solar?
Not usually. Change only if your load or your electricity company’s rules require it.
