Installation

6.5 Connections of the PV power system

Step3: Use the bracket to install the inverter onto the narrow vertical panel (or wall). Ensure the upper corner

of inverter is attached onto the bracket.

Step4: Make sure the bracket and the inverter’s right side screw hole are in line and matching well, fix the screw

into the hole and screw into the inverter tightly.

Step5: If necessary lock the inverter and the bracket with padlock (not included) for safety.

● PV String

SolarRiver inverters 3300TL, 4400TL and 5200TL have facility to connect two strings of PV moduleswhile

the other models can only take one module string. Use only PV modules with excellent performance and

reliable quality. Open-circuit voltage of modules connected in series should be ＜Max. DC input voltage of

the inverters (Ref Table 3) and the operating voltage at all times should be within the MPPT voltage range.

Only use good quality PV cables to connect modules to inverter. Normally the voltage drop between modules

and inverter could be about 1-2%. Hence inverter should be installed as close to the PV module as possible

to reduce cable losses.

Note！

Please don’t connect the PV panel positive or negative to ground.

Warning！

PV modules carry high DC voltage which is dangerous, please comply with all

electrical safety rules and regulations when working.

Warning！

In case of any faults with module arrays, do not connect the inverter to the

arrays.
