Modular Solar Inverters feature transformer-less design.
August 7, 2008 -
With 6 and 9 independent Maximum Power Point tracker inputs, Protect PV 25 and PV 33 deliver nominal power output of 25 kW and 33 kW, respectively, at European conversion efficiency greater than 95%. Modular design provides redundancy at inverter level; in case of module failure, 2 remaining modules keep working and alarm is initiated. Up to 20 inverters can be operated in parallel using specific RS-485 card. Web page tool displays all solar inverter information in single PC window.

Innovative Modular Solar Inverters - Foundation for Reliable Solar Power
Munich, June 12, 2008. Saft Power Systems (SPS), a worldwide leading manufacturer of premium power supply solutions, introduces two new family members of the Protect central solar inverters - Protect PV 33 and PV 25.
With up to nine independent Maximum Power Point trackers (MPPT) inputs the modular systems are designed to deliver a nominal power output of 25 kW (PV 25) and 33 kW
(PV 33) at a very high European conversion efficiency > 95 percent. Both systems boost the renewable power challenge by high efficiency, small footprint, low weight and a transformer-less design. With more than 50 years of experience in building first class power supplies in industrial designs Saft Power Systems' new solar inverters Protect PV 25 and PV 33 guarantee reliability and highest availability in the fast growing solar power market.
The new Protect PV 25 and 33 extends the family range of Protect solar inverters.
Six (PV 25) or 9 (PV33) independent MPPTs enhance the total solar efficiency by tracking optimum solar panel points at string level. The inverter tracks the current for all nine inputs. Individual strings can be connected to these inputs. Therefore additional string boxes are not necessary to monitor each string in order to detect technical problems within a solar panel.
The modular design of the Protect PV 25 and 33 provides redundancy at inverter level raising the availability of the complete solar installation or farm. In case of a module failure the two remaining modules keep working and an alarm is automatically initiated.
In this case the new solution provides a very fast Mean Time to Repair (MTTR). It can be dramatically reduced by easily replacing the defective unit by a new one - just plug & play.
Both models are equipped with a set of powerful local and remote communication capabilities. Up to 20 inverters can be operated in parallel by using a specific RS 485 card. A unique web page tool for administration and operation displays all relevant information of the solar inverters in a single PC window. Major information from the inverter can also be visualized on a local LCD without a PC. All data can be easily downloaded onto a USB-Stick for further analysis or set-up corrections.
An integrated data logger inside the Protect solar power inverter further secures its operation. With its 3-years record capacity it collects all relevant data. Therefore the data logger serves as an independent backup system in case the external PC for administration and monitoring fails.
Environmental protection by the use of solar power is enhanced by a lead-free manufacturing process according to the international RoHS rules.
The integrated cooling fans operate with a speed control to minimize wear and tear as well as reducing power consumption.
Protect PV 25 and PV 33 are available now.
In addition Saft Power Systems offers a complete range of compact, small footprint string solar inverters with power ratings from 1,5 kW up to 10 kW. The transformer-less and fan-less systems operate with more than 96 % efficiency and offer a plug & play installation for instant use. The integrated LC display visualizes all major information locally. Comprehensive communication interfaces are used for remote monitoring. For a secure outdoor operation of the inverters their dust- and waterproof cabinets are produced with IP 65 level of protection.
