5 Function
【
Fault Mode
】
If any fault/error occurs, inverter stops generating power until the fault/error is cleared. Some
fault/error will recover itself, and some may need to restart manually to resolve.
CAUTION!
The inverter output power decrease is usual
under
the condition of thermal
protection, but if it occurs frequently, you need to check the heat sink or consider
putting the inverter in the place where have better air flow, and if output power
decreases caused by electrical problem, please ask for professional supports.

6 Installation
6.1 Safety Instructions
Do not remove the enclosure upper lid. Inverter contains non-user practical parts. All wiring and
electrical installation should be conducted by a qualified service personnel and must meet national
requirements.
Both AC and DC voltage sources are terminated inside the PV Inverter. Please disconnect these
circuits before servicing.
When a photovoltaic panel is exposed to sunlight, it generates DC voltage. When connected to this
equipment, a photovoltaic panel will charge the DC capacitors.
Energy stored in this equipment’s DC capacitors presents a risk of electric shock. Even after the
unit is disconnected from the grid and photovoltaic panels, high voltages may still exist inside the
PV-Inverter. Do not remove the upper lid until at least 5 minutes after disconnecting all power
sources.
This unit is designed to feed power to the public power grid only. Do not connect this unit to an AC
source or generator. Connecting inverter to external devices could result in serious damage to your
equipment.
Carefully remove the unit from its packaging and inspect for external damage. If you find any
imperfection, please contact with your local distributor or service center.
Although designed to meet all safety requirements, some parts and surfaces of inverter are still hot
during operation. To reduce the risk of injury, DO NOT touch the heat sink at the back of the
PV-Inverter or nearby surfaces while Inverter is operating.
Check environment where system is installed.
Check whether the installation site fall into any of the following conditions:
●
The ambient temperature is beyond the range of the optional temperature limitation. ( -25°C to
+60°C, -13°F to +140°F),(Power derating begins at 45°C).
●
Installation altitude is higher than 2000m.
●
Prone to be damaged by sea water
●
Close to corrosive gas or liquid (for example, locations where chemicals are processed or the
location where feed lots of poultry).
●
Exposed to direct sunlight.
●
Prone to be damaged in flooding or icing time
●
Little air flow or high humidity.
●
Exposed to steam, vapor, or water.
●
Exposed to direct cool air.
●
Close to the television antenna or antenna cable.
6.2 Selecting the Installation location
The installation method and mounting location must be suitable for the weight and dimensions of
the inverter. Select a wall or solid vertical surface which is able to support the PV Inverter.
Mount on a solid surface, the mounting location must be accessible at all times.
Vertical installation or tilted backwards by max. 15°.
The connection area must point downwards.

6.6 Check Inverter Installation Status
Check the upper straps of Inverter to ensure it is fixed on to the bracket
Check the secure mounting of the PV-Inverter by trying to raise it from the bottom.
The PV-Inverter should remain firmly attached.
Select the installation location so that the status of display can be easily viewed.
Choose a strong mounting wall to prevent vibrations while inverter is operating.
6.7 Connector Guide
This product has a professional IP68 DC waterproof connector. You have to wire DC by yourself.
Please see
Figure 16
and
Figure 17
for DC connector disassembling guide.
Connectors must only be connected by qualified personnel
Only PV1-F cables can be used. The TÜV approval only allows the use of PV1-F cables. Do not
use type H07RN-F cables.
The connectors must be not disconnected while under load. For protection against electric shock,
connectors must always be disconnected from the power supply during assembly.
Connectors that are not plugged must be protected against humidity and contamination by a
protective cap. Any kind of contamination may have adverse effect on the system and great care
must be taken during assembly to ensure that everything is clean.
The Solar Family Series Inverter
20
Connectors provide IP68 protection but should not be continually exposed to water (e.g. immersed
under water) and not placed directly on the top side.
Connecting to PV panel (DC input):
