TOP 10 Reasons to choose Photowatt PWI Series inverters
1) Multi-string and Master/Slave : flexible self-configuration
Thanks to its 2 configuration types, the PWI series inverters offer a large flexibility for
installation : one inverter fits different PV system types without matters in connection ordering
as the inverter detects and choose automatically the best one.
2) MPP tracking: start gaining power even with low irradiation
The PWI Series assures the combination of two methods dedicated to work with high and
medium irradiation and also with low irradiation, meaning power production even with few light
and sun.
3) Auto detection: the intelligent inverter that automatically detects the PV-system
configuration.
This “Auto detection”-feature, unique in the market, is standard in all PWI
Series inverters. This feature increases the security for the installer when installing, and make
the installation more “plug and play”, reducing the installation costs.
4) Ride through : optimize safely your connection to the grid while grid disturbances
This technical inverters structure enables the inverters to smooth the grid disturbances by
monitoring automatically its connection. The PWI series inverters will disconnect only if the Ac
grid limits set by authorities are exceeded. This means no loss due to of non exploiting, and
protection of the installation and of all the components.
5) Derating: Protection of your inverters, protection of your investment
The de-rating function is implemented into the inverters in order to protect it against too high
power level, too high current, and too high temperature, by intelligently adapting its reaction to
these factors in order to maintain the best way to work.
6) International inverter: high standard technology
Operating on several markets is no longer difficult thanks to the high standard universal
technology of the PWI Series inverters. Inverters set up become easy for all the international
distributors and installers.
7) Galvanic isolation: installers security priority
Thanks to this photovoltaic isolation integrated into the PWI Series inverters manufacturing, the
installers are totally secured as it avoid him to electrical risks.
8) Options products: A full range to suit all the needs.
Indoor or outdoor, with RS485 or wireless, DC switch, you can choose into a full range of
options to suit your requirements and corresponding to your installation specifications.
9) Accessories products: Accessories to manage your installation
Wireless display, web logger, dataloggers, sensor kits, retrofit RS485, retrofit Wireless : a huge
range of accessories corresponding to the level of information you wish to download and check.
10) Supporting products: After sales and technical support
After sales department, hot-lines, “OptiGrid” sizing software, products and notes news : you
benefit from a real support in case of questions.
Fronius

The Fronius IG operates in a fully automated manner. As soon as the sun has risen and there is sufficient output generated by solar modules, the control unit starts monitoring the utility line voltage and frequency as well as the energy offer. When enough sunlight has been received, the solar inverter starts to feed the utility transmission grid and dependent on the type of installation, a few watts of solar power will do the job!
The Fronius IG will now continue to draw the maximum of power from the solar modules. This function is called MPPT (Maximum Power Point Tracking) and is carried out with a rate of accuracy of more than 99%. After dark, when the energy offered is no longer enough to feed the utility transmission grid, the Fronius IG automatically cuts the connection to the grid and stops operating, of course with all settings and data being conserved
The Fronius IG inverters are a reliable series and vary in size.
Fronius IG 15/20/30
This series offers the maximum flexibility . The PV inverter family works well with all solar panels available on the market. The ingenious processor control - the Fronius IG Module-Manager™ - and a large number of other enhancements makes them into perfect all-rounders. Due to the Fronius’ decades of research and development with incredible experience, they work reliably and efficiently in every class.
Fronius IG 40/60
Higher yield due to work-sharing is achieved by linking the two power circuits using the MIX™ concept, Fronius’ optimised master-slave system. In the part-load range only one of the two power stage sets operates, while both work together at full-load. The advantages are a noticeable increase in yield with a simultaneous reduction in operating hours.
As the input voltage range of the Fronius IG 60 has been expanded from the former 500 V to 530 V, longer module strings can be connected. Due to this improvement, the product name changed from “Fronius IG 60” to “Fronius IG 60 HV”. “HV” stands for “High Voltage”.
The Weatherproof –IG Outdoors
The Fronius IG Outdoors has created for outdoor use and tested to an IP45 degree of protection. This ensures a continuous circulation of air that prevents condensation from collecting as well as being protected against the entrance of solid particles and hose water. An added advantage for Cyprus, is that it is also reliable and safe to use near the sea due to the special protective coating applied to the printed circuit boards within the inverter.
Stand-alone inverters
Stand-alone solar systems are systems which enable an autonomous supply of electricity without connection to the AHK grid. Where there is no grid, such as isolated holiday cottages, mountain huts and villages, mobile homes and boats, these systems can satisfy all their power needs. In order to ensure supply at night, the captured electrical energy is stored in batteries with a charge regulator ensuring optimal charging of the batteries..
Mastervolt

The technology of using an inverter to obtain a 230V or 110V power supply from a battery is not new. Until now, however, the results were less than perfect as most inverters could only produce an output voltage that was not sine wave formed and the efficiency of the products were low. Mastervolt has optimised the inverter technology, resulting in the availability of a superb range of high efficient switch mode sine wave inverters.
