Product Description

Powerflow Sundial Slave 2kW

PowerFlow Sundial diverts and stores exported solar-generated power into the integrated Lithium Iron Phosphate battery pack. Next generation technology is deeply integrated into Sundial. At every opportunity, improvements have been made to the electricity conversion process to ensure the highest possible efficiencies are achieved.  This new patent pending storage technology results in a fully integrated system meaning no intrusive battery packs, inverters or wires are in sight. Instead, Sundial is fully integrated, can be wall hung in any home and is beautifully finished in Metallic Star Silver and Carbon Fibre.

  • Compatible with any existing or new PV system
  • Self-Regulating fast reacting capture and release of energy
  • Fully automated Plug and Play installation
  • Long lasting SAFE Lithium Iron Phosphate battery architecture
  • G83/2 compliant
  • Modular system for complete design flexibility
  • 10 year battery warranty, 5 year warranty electronics
