When accessing the internal circuit of inverter, it is very important to wait 5 minutes  before operating the power circuit or demounting the electrolyte capacitors inside the device. Do not open the device beforehand since the capacitors require time suﬃciently discharge! Surge protection devices (SPDs) for PV installation ...
Page 7 won’t stop conducting until the voltage across their terminals is typically more than 30 volts. Anti-Islanding Eﬀect  Islanding eﬀect is a special phenomenon that grid-connected PV system still supply power to the nearby grid when the voltage loss is happened in the power system. It is dangerous for maintenance personnel and the public.
Page 8: Explanation Of Symbol
2.2 Explanation of Symbol This section gives an explanation of all the symbols shown on the inverter and on the type label. Symbols on the Type Label CSA certified This symbol indicates that you should wait at least 5mins after disconnecting the inverter from the utility grid and from the PV panel before touching any inner live parts.
Page 9: Introduction
3. Introduction 3.1 Basic features Hybrid Series is a high-quality inverter which can convert solar energy to AC energy and store energy into battery. The inverter can be used to optimize self-consumption, store in the battery for future use or feed in to public grid.
Page 10 Note! Please control the home loads, and make sure it’s within the “BACK-UP output rating” under BACK-UP mode, otherwise the inverter will shut down with an “overload fault” warning. Please conﬁrm with the mains grid operator whether there is any special regulations for grid connection.
Page 11 Note! The arrow on the CT points to the power grid, as shown. If the CT connector is improperly connected, the inverter cannot read the data correctly, so that the relevant working conditions cannot be realized normally.
