5 Function

Operation Mode

【 Stand-by Mode】

The stand-by mode means that the inverter is ready to but still not connect to the grid.

Under this mode, it will continue check if PV array has enough power to feedback into grid. When the inverter passes dump load test after startup, it will change from stand-by mode to Checking mode.

【 Checking Mode】

If inverter passed dump load test and no error/fault occurs, starts checking to deliver power.

【 On-grid Mode】

Under this mode, SolarRiver series inverters convert PV array’s DC into AC and feedback into grid.

CAUTION!

The inverter decreases the output power is normal in the condition of thermal protection, but if this phenomenon occurs frequently, you need to check the heatsink and the fan, or consider putting the inverter in the place where have better air flow. If the fan is too dirty, please clean it, and if output power decreases caused by electrical, please ask for professional supports.

【 MPPT Mode】

The default setting is MPPT mode, the operation mode will return to MPPT after

DC&AC restart.

【 Fault Mode】

If any fault/error occurs, inverter stop delivering power until the fault/error is clear. Some fault/error will auto recover, and some may need manual restart.

【 Setting Mode】

The user can get into the setting mode by press “Function” key for 5 seconds if DC exists.

Please refer to operation method in chapter 7 for detailed information.

electricity, so please wait for at least 5 minutes to ensure the capacitors

completely release the energy and inverter is not electrified.

Note

Inverters must be installed by qualified person.

6.2 Installation precaution

Checking environment where system is installed

Check whether the installation site does not fall into any of the following conditions:

●The ambient temperature is outside the range of tolerable ambient temperature ( -20°C to +60°C, -4°F to +140°F,).

● Higher than the altitude of about 2,000 m above sea level.

● 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 flooded or high levels of snow pack.

16

● Little or no air flow and high humidity.

● Exposed to steam, vapor, or water.

● Exposed to direct cool air.

●Near the television antenna or antenna cable.

● Ventilation is not enough to cool the inverter, that is to say, outdoors, the inverter requires. At least 30 cm (see table 2) of clearance among the units is needed, it is recommended that the same clearance between the units and the ground be used.

Installing the inverter in the place mentioned above may cause the malfunction of the

6.3 Preparation

Below tools are needed before installation.

Installation Tools

Installation Tools: crimping pliers for binding post and RJ11, screwdriver and manual wrench and ф 6 driller.

6.4 Installation Steps

Step1: Drill holes in the wall with ф 6 driller according to the size of bracket. Keep drilling vertical to the wall, and don’t shake when drilling to avoid damage to the wall.

17

The depth of the holes should be about 30mm and should be the same. After removing the dust in the holes, measure the net depth of the holes. If the depth is more than 33mm or less than 27mm, the expansion tubes wouldn’t be installed and tightened.

Figure 7 Installation of Expansion Pipe

Step2: Clean all dust outside/inside the hole and measure pitch-row before installation. It need repositioning and drilling holes if the hole with much error. Then put expansion pipe into the hole vertically, use rubber hammer to tap the pipe into the wall completely. After that, twist 2 screws into 2 corresponding pipes, another 2 screws should be twisted into pipes with gasket.

Figure 8 Bracket Installation

Step3: Use the bracket to install the inverter onto the narrow vertical panel (or wall). Put upper-part holes of the inverter onto the bracket, lower part onto the M5 screw rivet of the bracket (See figure 8).

Step 4: Use M5 flange nut to fix the bottom of the inverter.

Step 5: Complete the installation process.

One inverter can only be communicated with one PC at the same time through RS232 port. Thus this method is generally used for single inverter’s communication, for examples,software updating and serviceman’s testing.

② RS485 Communication (Several inverters)

●Communication

RS485 is generally for multi inverters’ communication. Up to 32 inverters could communicate at the same time, but wire length should be≤1200m. System monitor

SolarPower Manager should be configured to realize one PC communicates with multi inverters at the same time. Through PC SolarPower Manager could get real time PV plants operating data. Please see Installation Guide of SolarPower Manager for more information.
