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.

Figure 11 Connection of the connector

● 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.
