tive or negative polarities of PV strings do not short-circuit to the ground. Other-
wise, the product may be damaged. And the damage caused by this is not covered
by the warranty.
Comply with the safety instructions related to PV strings and the regulations re-
lated to the local grid.

• Be sure to use special insulation tools when perform high-voltage operations
• Before maintaining the optimizer, first cut off the power input and the power
output, and measure the voltage and current with professional measuring in-
strument. Only when there is no voltage nor current can operators who wear
protective equipment operate and maintain the optimizer.
• Even if the product is shut down, it may still be hot and cause burns. Operating
the product with protective gloves after it cools down.
If a fault occurs during operation, be sure to re-power the optimizer after the fault
is cleared. Otherwise, the fault may expand, or the device may be damaged.

2Product Description
2.1 System Introduction
SP600S optimizer is mainly used to adjust the voltage and current of each PV module in real
time to track the maximum power point of each module, thus improving the power genera-
tion capacity of the PV system. It can also realize module-level shutdown, module-level IV
curve scanning and automatic physical positioning.

figure 2-2 Application to Industrial and Commercial System
2.2 Working Principle
The working principle of the optimizer is shown in the diagram below. Connected to the PV
module by its input cable, the optimizer can track the module's maximum power and output
the desired voltage through a DC/DC voltage conversion circuit.
