Mastervolt CS7TL RP

Central String inverter that fits your system

The SunMaster CS solar inverter builds on 20 years of experience and know how by the Mastervolt R&D centre in Amsterdam. This results in key features such as conversion efficiencies up to 98%, extremely low system losses and a wide input window up to 1000 V.

Quick installation, low maintenance

The SunMaster CS comes with a mounting bracket and a waterproof AC plug for quick and flexible installation. Integrated handles assist in moving and lifting the CS with ease. Once installed, the SunMaster CS requires very little maintenance.

Maximum annual yield

The SunMaster CS is developed based on Mastervoltâ€™s unique philosophy. In addition to

maximum efficiency, we focus on high yields in less than optimal conditions. As a result, the SunMaster CS has various exclusive features:

· By starting up at optimal voltage, the SunMaster CS extends the solar day, while its low no-load consumption helps convert solar power down to the last ray of sun.

· The SunMaster CS is immune to minor electricity failures and only goes offline when absolutely necessary.

· The MPP tracker tracks the light conditions quickly and carefully, even in changing weather conditions. Tests in realistic conditions show that 99.8% of the available PV power is converted!

· The transformerless non-isolated SunMaster CS achieves a stable and high conversion efficiency over the whole input range.

· The SunMaster CS stays cool, even in warm outside temperatures, maximizing efficiency and lifespan.
