1.Photovoltaic panels must be connected in series to the PV port; parallel connection is not supported.
2. Only the original MC4 connector kit included with the box must be used.
3. Before inserting string plugs into the inverter, measure open-circuit voltage (Voc) with a multimeter to ensure each PV string voltage remains below 400V.
4. Photovoltaic modules: Ensure they share identical models, output specifications, and mounting configurations, with all modules angled at the same degree.
5.To conserve cable length and minimize DC losses, we recommend installing the inverter as close as possible to the photovoltaic modules.
6. Ensure that the photovoltaic cables connected to the inverter are vertically connected with a vertical length exceeding 30 cm. Bending cables near terminals may cause poor circuit contact and lead to terminal burnout.
Warning ：
1. The photovoltaic module voltage is extremely high and falls within the hazardous voltage range. Strict electrical safety regulations must be followed during installation.
2.It is strictly prohibited to directly ground the positive or negative electrode of photovoltaic systems, as this may trigger fatal short-circuit faults.
3.Before performing any physical connections, ensure the DC switch of the inverter is completely turned off.
