Electrical connection
Note
If several SolarRiver-US inverters are installed in a three-phase AC GRID, it is
recommended to distribute the inverters between the phases in order to reduce the power
unbalances between the phases. Always refer to the local standards.
5.4 DC wiring
This section provides complete, step-by-step procedures for wiring the DC input from the PV array to the
SolarRiver-US inverter.
Warning
High voltage is present in PV modules exposed to light. Death due to electric shock when
touching a DC conductor. During installation, cover all PV modules using opaque material.
Warning
High voltage is present inside the DC cables. Death or serious injury will result when damaging
a DC cable or touching a DC conductor. You have to connect the DC cables from the PV array
to the SolarRiver-US inverter in the order described in this manual.
Warning
The input current shall not be exceed 17 A DC for each input channel (SolarRiver 7000TL-US),
19A DC (SolarRiver 8000TL-US), 18A DC (SolarRiver 9000TL-US) AND 20A DC (SolarRiver
10000TL-US).
Warning
Verify that the DC voltage in DC terminals block has the correct polarity and is within the
operational range.
SolarRiver -US can be configured as an individual MPPT for each DC input channel, or configured as single MPPT for
the two input DC channels connected in parallel. If the inverter is configured as two individual MPPTs, the max current
for each channel shall not exceed 17 A DC for each input channel (SolarRiver 7000TL-US), 19A DC
(SolarRiver 8000TL-US), 18A DC (SolarRiver 9000TL-US) AND 20A DC (SolarRiver 10000TL-US).
