Dc Connection - Omnik Omniksol-5KW-TH-TL3-NS User Manual

5.3 DC Connection

DANGER!
Before electrical connection, cover the PV battery modules with light-
proof material and disconnect the circuit breaker on the DC side.
WARNING!
This product is a non-isolated inverter, the positive and negative
electrodes of the PV module cannot be grounded, otherwise it will emit
PV ISO Fault. The inverter cannot operate normally even be damaged.
CAUTION
When designing PV arrays, the open-circuit voltage of each PV string
less than 1000 V must be considered, and the maximum allowable
short-circuit current for each PV string is no more than 12 A.
NOTE
All models of inverters are featured with two MPPT inputs and two
groups of input terminals, and two groups of PV strings can be
connected to the DC side.
DC connection terminals are included in scope of delivery. Please connect the DC cables
selected based on the above requirements to the connector by following the steps below.
(Note: During connecting, use the same color for the positive cables with a mark and use
another same color for negative cables with a mark. For example, generally red cables are
used for the positive terminal and black cable are used for the negative.)
