SOLAREDGE SINGLE PHASE INVERTERS
The SolarEdge system consists of PowerBoxesTM 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 PowerBox is mounted behind and connected to each module. At least 8 modules PowerBoxes must be used, so your system can start as small at 8 modules with wattages up to 350W each. The output of the PowerBoxes 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 PowerBoxes 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 PowerBoxes 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 PowerBox per module. The inverters work with 208 and 240 VAC systems (because the MPPT and voltage management is handled by the PowerBoxes), 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 PowerBoxes 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.
module in a user’s system and transmits data to the
Enlighten™ website, where users can view their solar
power system performance. The Envoy can be plugged into
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
free. The Enlighten website provides information on
solar system performance. A graphical representation of
the solar array provides information on the status of
each module.
Designed
for easy installation, simple communication and maximum
performance. With high efficiency, a slimline enclosure
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,
field configuration for positive ground and a wide input
voltage range of 175 to 600 volts, which provides
increased system flexibility. The graphic display and
wireless Bluetooth® communication system also makes the

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
