SwitchMaster 2-3 SW30 OVP

SwitchMaster 2-3 SW30 OVP

The strings are connected in a string box, which is installed between the PV array and the SunMaster CS inverter. The high DC loads and currents require top quality and safe components. The varistors in the StringMaster reduce the risk of lightning strike damage to the PV array, cables and inverter.

Why a separate string box?

  • Safe and practical solution; the string box allows you to switch the PV modules on and off at close range.
  • Saves labour and material costs by reducing up to ten strings to only two.
  • The IP65 string boxes are developed in accordance with HD60364-7-712 and EN60439-1, and come with clear safety instructions.
  • Equipped with high quality components such as a 1000 V DC switch and reliable 16 mm² connections, and placed in a fully assembled enclosure with coupling nuts.

 Which string box do I need?

"choice

Select the right fuse

Choose breaking capacity: In > Isc x 1.56. Example: Isc = 7.95 A  --> 7.95 x 1.56  = 12.4 --> next higher rating --> choose 15 A fuse.          

StringMaster fuses are marked with the ‘gPV’ and ‘fuse"drawing’ symbols, showing compliance with IEC60269-6. Use of non-compliant fuses is prohibited as it may lead to severe damage or even fire.
