Solar (Dc) Connection; Pv Terminal Connections - Pyramid 5 KW 3 Phase User & Installation Manual

ˆ Finally tighten the cable gland.
Note: Before connecting female connector to the male part, match the white dot
provided on both connector and then insert the female connector. Finally tighten the
connector shell.

Solar (DC) Connection

Note that the present inverter is a functionally ungrounded array solar inverter. This means that none
of the input dc terminals (PV+ or PV-) can be connected to earth/ground. If any of the dc input
terminals is connected to ground, the inverter will not start-up and can lead to permanent damage of
the inverter.
5.2.1

PV Terminal Connections

Caution: Solar PV String can be directly connected to the solar inverter without using any DC
circuit breaker.
Note: Automatic built-in dc switch exists within the inverter. The control electronics of the inverter
is powered up from the grid side. Basically, the inverter WILL NOT turn ON once the solar string is
connected. The inverter will only be turned on once the grid side circuit breaker is turned ON. Note:
Please use 1000 V DC / 20 A circuit breaker for the present 5 KW 3 Phase Grid-Tied Solar Inverter
if required.
WARNING!! This inverter is compatible with any type of PV modules: single crystalline, poly
crystalline and thin film PV.
ˆ Check the input voltage of PV array modules. The acceptable input voltage of solar inverter is
100 V DC - 1000 V DC. This system has a single input, please make sure that the maximum
current of PV input connector is less than or equal to 17 A for present 5 KW 3 Phase Grid Tied
Solar Inverter.
CAUTION: Exceeding the maximum input voltage can destroy the unit!! Check the system
before wire connection.
