Sungrid Inverters



Dayliff SUNGRID are transformerless inverters for the management of hybrid solar powered PV/AC mains power supply installations. The inverters convert the PV generated DC power to AC, either single or threephase depending on model, and feed to the applied load prioritising the PV output, supplementing with AC mains power if there is insufficient PV generated output for the load. Inverters are fitted with MPPT trackers to optimise output efficiency and single-phase units are fitted with an inbuilt export limit function that prevents excess PV power being transmitted to the grid. Three phase units require an external controller.

SUNGRIDs are designed to be connected in parallel each fed from dedicated solar arrays that can provide power outputs of limitless size. Wi-fi connectivity is provided that enables remote monitoring and data transmission.

Particular features include:-

  • LCD screen and LED status indicator display. 3 phase has multifunction buttons for ease of operation and maintenance
  • RS232/WIFI/GPRS external remote monitoring options.
  • Built in protection including DC reverse polarity, short circuit, output over current, over voltage, insulation resistance monitoring, residual current detection, surge protection, anti-island protection and over-temperature protection.
  • Dayliff SUNGRID are lightweight and compact in size with high overload capacity, high PV energy consumption efficiency, excellent thermal performance and low maintenance needs and are an ideal solution to the application of PV power generation for hybrid PV/mains supply power supply systems.
