Installation
Please use PV cable to connect arrays to inverter. From junction box to inverter, voltage drop is about
1-2%. So we suggest the inverter be installed near PV arrays, in order to save cable and reduce DC loss.
Note
！
Please don’t connect the PV positive or negative to ground.
5.7.3 Connection steps of DC connector
●
Assembly steps of DC connector
Step1: Inserting the stripped conductor, Cross-sections 2.5 to 6 mm2, Outside diameter 5.0 to 8 mm,
Stripping length 15 mm.
Step2: Close spring with the thumb or using combination pliers. Please ensure that the spring is closed.
(see figure 11)
Step3: Push connectors together (see figure11). Screw cable gland tight. Screw in the nut until it reaches
the O-ring and then tighten it with at least 2 Nm using a suitable tool. Finished.

Electrical connections of DC side
Step1: Install the breaker or SolarArray Combiner in the DC side.
Step2: Disconnect the breaker or SolarArray Combiner with SolarRiver-D inverter.
Step3: Ensure open-circuit voltage of PV arrays is<1000V.
Step4: Put the positive and negative connector into the terminals on the bottom of inverter.
