# How to create a 3 phase system with xtender?

A 3-phase system can be created by combining 3 xtender inverter/chargers. You can use different models in each phase as long as they use the same battery voltage. Because the battery bank is common to all of them.

Examples:

| **L1** | **L2** | **L3** | **CORRECT?** |
| --- | --- | --- | --- |
| ** **xtm 2400 - **24** | xtm 2400 - **24** | xtm 2400 - **24** | YES |
| xtm 2400 - **24** | xtm 3500 - **24** | xth 5000 - **24** | YES |
| xtm 2400 -  **24** | xtm 4000-  **48** | xth 3000 -  **12** | NO |

**Step 2: Communication Wiring**

All xtender family systems must communicate through the Studer bus to synchronize and share information. In this particular case, it is also needed to manage phase shift between the different inverters.

**Step 3: Phase Selection Jumpers**

Adjust phase selection jumper in each xtender (images below xth, xtm and xts):

- xtender 1: Jumper in L1
- xtender 2: L2 (L2 with 120 degrees phaseshift)
- xtender 3: L3 (L3 with 240 degrees phaseshift)
