CS12TL 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 Mastervolt’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.

Reactive Power settings

Depending on local regulations, utilities may require provision of reactive power. All SunMaster CS models are fully prepared for the German low voltage directive VDE-AR-4105, the German medium voltage guidelines published by BDEW, and meet the requirements for low and medium-high voltage in Italy; CEI-021. These features will be activated when the corresponding country is selected during commissioning.
