Electrical connections
Before making any electrical connections, make sure that the DC circuit breaker is switched off. The
stored electrical charge remains in the capacitor after the DC circuit breaker has been switched off, for
safety reasons, wait 5 minutes for the capacitor to discharge completely.
The HYD 10-20KTL-3PH inverter is intended for use in a photovoltaic system with battery storage; if
not used as intended, the protection provided by the equipment may not function properly and may be
impaired.
The PV modules generate electricity when exposed to sunlight, and can create
electric shocks. Therefore, before connecting the DC power cord, cover the PV
modules with a dark covering.
Danger
The inverter must be installed and serviced by a professional electrician. Wear
protection equipment when working on high voltage/high current systems
such as inverters and battery systems.
Attention
For the HYD 10-20KTL-3PH inverter, the open-circuit voltage (Voc) of the
strings related to the modules connected in series must be ≤ 1000V
Note
The PV modules must have an IEC 61730 classification of Class A.
