In Palermo, within a semi-detached house, I.M.E.R.T. S.N.C. has recently completed a project to replace and upgrade an existing photovoltaic system, choosing a Heiwit solution to improve system performance and increase available storage capacity.

The intervention was born from the need to replace a previous system that presented problems related to monitoring and parallel operation management.

From the existing configuration to a more performant solution

The original system consisted of:

  • 10kW inverter
  • 6 kWh storage system

The new configuration installed by I.M.E.R.T. S.N.C. instead provides for:

  • Heiwit 12 kW inverter
  • Heiwit 20 kWh Sodium-ion battery storage system

An important update that has increased both the inverter's power and the available storage capacity.
