The SolarEdge power harvesting solution is designed to maximize the power output
from any type of solar Photovoltaic (PV) installation while reducing the average cost
per Watt. Figure 1 shows and the following sections describe the components of the
SolarEdge power harvesting system.

Figure 1: The SolarEdge power harvesting system components
Power Optimizer
The Power Optimizers are DC-DC converters connected to PV modules to maximize
power harvesting by performing independent Maximum Power Point Tracking (MPPT)
at the module level.
The Power Optimizers regulate the string voltage at a constant level, regardless of string
length and environmental conditions.
The Power Optimizers include a safety Voltage function that automatically reduces the
output of each Power Optimizer to 1 Vdc in the following cases:

Three Phase Inverter with Synergy Technology
The Three Phase Inverter with Synergy Technology (referred to as 'inverter' in this
manual) efficiently converts DC power from the PV modules into AC power that can be
fed into the main ACservice of the site and from there to the grid. The inverter also
receives the monitoring data from each Power Optimizer and transmits it to the
SolarEdge Monitoring platform (requires a land-line or cellular connection to the
Internet).
The inverter is comprised of one Synergy Manager with DC Disconnect Switch for
disconnecting the DCpower, depending on the inverter's model. The Inverter may
include two or three Synergy Units, depending on the inverter's model.
The Synergy Unit are connected to the Synergy Manager via AC, DC and
communication cables.
Each Synergy Unit operates independently and continues to work in case others
stopped operating.
A chain of up to 31 inverters can be set to operate together via Modbus on RS485 line.
When setting a chain of inverters, the inverter that manages communication interface
to the internet is called Leader and the rest are Followers.

IMPORTANTSAFETYFEATURE
Modules with SolarEdge Power Optimizers are safe. They carry only a low safety
voltage before the inverter is turned ON. As long as the Power Optimizers are
not connected to the inverter or the inverter is turned OFF, each Power
Optimizer will output a safe voltage of 1V.
CAUTION!
Installing a SolarEdge system without ensuring compatibility of the module
connectors with the Power Optimizer connectors may be unsafe and could
cause functionality problems such as ground faults, resulting in inverter shut
down. To ensure mechanical compatibility of the SolarEdge Power Optimizers’
connectors with the PV modules’ connectors to which they are connected:
Use identical connectors from the same manufacturer and of the same type
on both the Power Optimizers and on the modules; or
Verify that the connectors are compatible in the following way:
The module connector manufacturer should explicitly verify compatibility
with the SolarEdge Power Optimizer connector; and
A third-party test report by one of the listed external labs (TUV, VDE, Bureau
Veritas UL, CSA, InterTek) should be obtained, verifying the compatibility of
the connectors.
