SOLAREDGE SINGLE PHASE INVERTERS
The SolarEdge system consists of PowerOptimizersTM which perform module-level MPPT, a highly reliable inverter, and a web portal for module-level monitoring and fault detection. In a SolarEdge system, a PowerOptimizer is mounted behind and connected to each module. At least 8 modules PowerOptimizer must be used, so your system can start as small at 8 modules with wattages up to 350W each. The output of the PowerOptimizer are wired in series “strings” just like a typical grid connected system, but strings can be made of 8 to 25 modules and several strings of different numbers of modules may be connected to the same SolarEdge inverter. This allows the homeowner to put as many solar modules on a roof that can fit in allowable space. Modules can be partially shaded and can even be on different planes of the roof. Different brands and wattage modules can be used in the same string, making it easy to add to an existing system later or to replace a failed or broken module. When the modules with PowerOptimizer are installed, the installer can safely handle the wiring because there is only one volt output per module until they are connected to the inverter and the inverter is turned on. The installer will know if the wiring is correct by counting the modules and making sure there is one volt per module in each string. This allows for the quantity in series and the polarity to be easily verified. If maintenance is required, you can turn off the inverter and the output again drops to one volt per module. This also eliminates the risk to firefighters because turning off AC power to a building turns off the inverter and this drops the module strings to safe low voltage.
SolarEdge’s module-level monitoring allows the installer and
homeowner to see the output
The best part is that a PV system with SolarEdge PowerOptimizer and
a Solar Edge inverter costs no more than a system with a
conventional string inverter and monitoring equipment and
actually costs less than micro-inverter To design a system, measure the roof or installation location and see how many PV modules you can fit in the available space. Order one PowerOptimizer per module. The inverters work with 208 and 240 VAC systems (because the MPPT and voltage management is handled by the PowerOptimizer), have built-in AC and DC Disconnects, weigh 52 pounds, and are 97.5% CEC weighted efficient. Order the appropriate SolarEdge inverter by choosing one with a power output equal to at least 90% of the total wattage of all of the modules in the systems. SolarEdge makes inverters with AC outputs of 3.3, 4, 5 and 6 kilowatts. For systems larger than 6 kW, use multiple inverters. The system also offers optional wireless inverter connectivity for simpler installation, free of Ethernet or RS485 cabling. ETL Listed to UL 1742 for the US and Canada. 25-year warranty for the PowerOptimizer and 12-year warranty for the inverter (extendable to 20 years).

The
new OutBack Power Technologies Radian Series GS8048
Inverter/Charger provides a comprehensive answer for
grid interactive and stand-alone power systems. Based
upon a proven foundation of reliable technology but
engineered from the ground up to simplify the design,
distribution, installation and implementation of energy
storage, the standardized structure and integration with
the GS Load Center make it easy to provide a successful
solution to any power requirement, anywhere.
The
Aurora PVI series are some of the most flexible string
inverters available. PVI inverters have two separate
MPPT inputs, allowing for two sub-arrays to be
configured with differing string lengths, orientations,
or even different PV modules. Conditions on one string
will not affect the other. Additionally, the PVI
inverters have two input terminals for each separate
MPPT section allowing as many as four strings of modules
(two on each MPPT) to be connected without separate
string fusing. Both MPPT inputs can also be paralleled
for use with a single array. A wide input voltage range
allows for low wattage installations with reduced string
sizes where needed. 3, 3.6, 4.2, 4.6, 5 and 6kW
Inverters are available (not all listed).

DC output from multiple solar modules into AC power. A
micro-inverter system mounts behind a solar panel and
converts the DC output of the solar module into
grid-compliant AC power. This simplifies the
installation, increases eff iciency, avoids high voltage
DC wiring and the requirements for conduit and DC
switch-gear. Micro-inverters also allow the home owner
to add to their system as budget allows, starting small
and growing the size of the system over time. PowerOne
offers higher wattage micro-inverters for use with
today’s higher output panels.

a 120v AC outlet. Enphase Micro-inverters transmit data
over the existing power line, so no additional wiring is
required. Simply connect an Ethernet cable from the
Envoy into a broadband router. Monitoring is provided

and reduced weight, the Sunny Boy HF series of inverters
can be mounted in between wall studs, making it perfect
for new construction and space constrained remodels.
Installation is made simple by automatic grid detection,

On
typical grid connected installations, the system is made up of
“strings” of solar modules wired in series to achieve a voltage
that matches an inverter’s input voltage specification. All
strings of modules in a system must contain the same number of
modules. Most grid-tied inverters allow 9 to 12 typical 60 cell modules
to be used in each string. This severely restricts how many
modules used in a PV system and as soon as the
modules are connected in series the wires from the modules to
the inverter start carrying potentially lethal voltage whenever
the sun is out.
