Benefits for the installer and investor

ROI and return on investment: in a typical 100 kWp PV farm in Polish conditions (~950–1050 kWh/kWp per year) an inverter of this class generates 95–105 MWh of energy per year. At business energy rates of PLN 0,85–1,20/kWh net income of PLN 80–125 per year, and the simple payback period (SPBT) of the entire installation is 5–7 years.

Operating savings: high European efficiency above 98% translates into 1,5–2 MWh more energy per year compared to 97% efficient inverters – that's several thousand zlotys of additional income during the warranty period.

After-sales support PVGroup.pl: advice on the selection of a MV/LV transformer and DC/AC cable, support in the design of the connection to the DSO, quick warranty replacement (swap model), access to service parts and recommendations for operating parameters for the conditions of the national grid.

B2B Financing: VAT invoice, operational and financial leasing, NFOŚiGW loans for renewable energy sources – contact your sales representative for an individual offer for 100 kWp+ projects.

Installation and commissioning

The installation of MAX series inverters must be performed by an electrician with valid qualifications. SEP E and D up to 1 kV (for the 1500 V version – 1 kV authorizations plus dedicated manufacturer training). Typical implementation process: (1) electrical design, (2) application for connection conditions to the DSO (Tauron, PGE, Enea, Energa, stoen), (3) connection agreement, (4) mechanical and electrical installation – 1–2 days for 100 kWp, (5) reporting the installation to the DSO and post-installation measurements, (6) commissioning and parameterization of Q(U)/P(f) curves. Total time from order to first commissioning: 6–14 weeks depending on the DSO.
