BATTERY CONNECTION

- Take care not to cause electric shock or chemical hazards
- Plug in the DC circuit breaker (≥ 40A) between the battery and the inverter.
Make sure your batteries are switched off before connecting and the ET series is disconnected from
the FV and AC sides[4].
Follow strictly the instructions below.
Using the wrong conductor can result in poor contact and high impedance, which is dangerous for the
system.
- Use the correct BAT connector from the accessories.
- Use tinned cables with a 4 to 6 mm2 (AWG 10) cross-section, as the maximum battery current is 25A.
