PV String Design
Calculated configuration: 2 strings of 18 modules, one on each of 2 of the 4 MPPTs (the other 2 remain free for future expansion). Operating voltage Vmp 603 V, Voc at 25 °C 725.4 V, conservative Voc at −25 °C 812 V — within the inverter’s 1000 V limit and within the 200–850 V MPPT window. Maximum current per MPPT 15.1 A, within the 20 A limit. Module used: Trina Vertex S+ 505 W N-Type TOPCon bifacial Full Black (Vmp 33.5 V, Voc 40.3 V, Imp 15.09 A, Voc coefficient −0.24 %/°C). DC/AC oversizing ratio: 1.21×. Preliminary configuration: to be re-checked against the datasheet of the revision actually purchased and the site conditions.
Storage, Grid and Operation
- ✓Grid-connected operation.
- ✓LiFePO₄ batteries not included in this configuration.
A consistent, well-engineered system
The kit uses selected components and a PV configuration sized to the inverter’s electrical limits, for a robust, consistent commercial or industrial system ready for installation by qualified personnel. The kit includes only the specified PV panels, inverter, and AC and DC protection panels. Mounting structures, cables, connectors and installation are not included and must be sized by the installer to suit the site. Installation and grid connection must be carried out by licensed personnel.
