Function
Operation Mode
【Stand-by Mode】
The standby mode means that the inverter is ready for operation but still not connected to the grid. In this
mode, it will continue to check whether PV array has enough power to feedback into grid. When the
inverter passes dump load test after startup, it will change from standby mode to Checking mode.
【Checking Mode】
If inverter passes dump load test and no error/fault occurs, will start checking mode to deliver power.
【On-grid Mode】
In this mode, SolarRiver series inverters convert PV array’s DC into AC and feedback into grid.
Caution!
It is normal that the inverter decreases the output power in the condition of
thermal protection, but if this occurs frequently the heat sink and the fan will
need to be checked and the inverter may need to be shifted to a place with

Installation
【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 will stop delivering power until the fault/error is rectified. Some fault/
error will recover automatically, and others may need manual restart.
【Setting Mode】
Press “Function” key for 5 seconds to get into the Setting mode if DC power exists. Please refer to chapter

8.1
Communication and Monitoring
Communication Interface
SolarRiver inverters have communication interface RS485 and /or RS232 depending on model. Output voltage,
current, frequency, fault information, etc., can be delivered to a PC or other monitoring equipment via the
RS485/RS232.
8.2
Communication types
SolarRiver inverters come with one or both of the following types communication facility depending on
model.
① RS232 Communication
RS232 is a standard communication interface within 12m. It transmits data between PC and one SolarRiver
series inverter (Figure 22).

Only one inverter can be connected with a PC at one timethrough RS232 port. This facility is generally
used for single inverter communication, software update and testing by service person.
②
RS485 Communication
● Communication
RS485 allows upto 32 inverters to communicate at the same time. But the total cable length should
not be more than 1200m. SolarLog can be used for monitoring multiple inverters at the same time.
Users can browser the PV plants operating data collected by SolarLog through PC. Connecting the
system as blow (figure 24), user can easily monitoring the PV power station.
