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.

SolarRiver 1700TL~3000TL Inverter Backboard SolarRiver 3300TL~5200TL Inverter Backboard Warning！ before installation and maintenance, AC and DC side doesn’t carry electricity, but if DC side is just disconnected, capacitance still contains 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.
● 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.
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.
SolarRiver series inverters (SolarRiver 3300TL/SolarRiver 4400TL/SolarRiver 5200TL) can be connected in series into 2-strings PV modules. Please select PV modules with excellent function and reliable quality. Open-circuit voltage of module arrays connected in series should be ＜Max. DC (Table 3) input voltage; operating voltage should be conformed to MPPT voltage range. Table 3 Max.
Warning！ When there is something wrong with module arrays, modules can be connected with PV grid-tied inverter only after eliminating these problems. ● AC Output SolarRiver series inverters are designed for single phase grid. Voltage range is from 180V to 260V (200V-270V for Australia), typical frequency is 50Hz. Other technical requests should comply with the requirement of local public grid.

Figure 15 AC Connector Step3: Confirm all the wires should be screwed down( Figure 16).
Step5: Screw down the pressure screw (Figure 18). Figure 18 Step6: Connect AC connector to inverter (Figure 19). Figure 19 6.6 Run the inverter ·Start inverter after checking all below steps a. Make sure all the DC breaker and AC breaker are disconnect. b. AC cable is connected to grid correctly. c. All PV panels are connected to inverter correctly，DC connectors which are not used should be sealed by cover. ·Start inverter a. Turn on DC and AC side switches. b.
greater than 100V (lowest start-up voltage) but less than 150V (lowest operating voltage). Checking: Inverter will check output environment automatically when DC output voltage of PV panels exceeds 150V and PV panels have enough energy to start inverter. Normal: Inverter begins to operate normally with green light on. Meanwhile, feedback energy to grid, LCD displays present output power, inverter will stop feedbacks power to grid when PV power is not enough.
