1. INTRODUCTION
1.1 Prefix
Dear customer, thank you for choosing the BDM‐250 micro inverter from NEP.
We hope you will find our products meet your need for renewable energy.
Meantime, we appreciate your feedback regarding our products.
1.2 Grid-tied PV System
Grid‐tied PV system consists of PV panels, grid‐tied inverter and junction boxes. The DC output from the PV
panels is converted into AC energy and feedback to the grid through the BDM‐250. BDM‐250 series PV micro
inverter contains isolation transformer with basic insulation between PV input and AC grid output. The PV
panel terminals on BDM‐250 shall not be earthed via external wiring, for BDM‐250 connects PV panel to
earth via an internal earth fault interrupting fuse.
