Questions and answers
можно ли подключать инвертор SOFAR 1.1K – 3.3KTL-G3 в параллель в 3-х фазную сеть. и какая величина входного напряжения постоянного тока от солнечных батарей должна быть
The Sofar Solar inverter 1.1K-3.3KTL-G3 cannot be connected in parallel to a three-phase network, as it has a nominal grid voltage of L/N/PE (single-phase) 220V/230V/240V.
The required DC input voltage from solar panels must be within the MPPT voltage range of 50–500V (for lower models) or up to 550V depending on the specific model. The start-up input voltage is 70V.
