    Tips for optimal use In this section we will give you useful tips to make the most of your UNE ZHERO. All it takes is a few tricks to be able to consume in a 'smart' way while saving energy and not giving up your comforts.
  • Page 88 These are tips for optimal use, everything will continue to work smoothly even if the battery runs out. Furthermore, the battery available in the UNE ZHERO S10 has a high capacity; it is likely that, no matter how much you consume with heavy appliances (ovens, washing machines, etc.), it will not last overnight to finish its charge.
  • Page 89 With this in mind, you should start using all the electrical appliances in your home (iron, hoover, etc.), making sure that you have chosen the UNE ZHERO model with the appropriate battery capacity for your uses, so that this capacity is sufficient to cover your night-time needs.

  • Page 94 10.13. “Retrofit – Hybrid” function UNE ZHERO Retrofit or Hybrid is set up to operate in such a way as to accumulate excess energy during the day and then distribute it to the user. Therefore, the user will first use the energy produced by its internal MPPT controllers (Hybrid configuration), then by the grid inverter, then that stored by the battery pack, and finally, only, if necessary, that from the distributor's grid.
  • Page 95 The battery pack is recharged following its own charging curve, so it is common during the day for overproduction to be released to the grid even though the battery is charging. This means that the optimal way to store the energy produced is on long days with average brightness, rather than short days with high production peaks.

  • Page 96: Fault Signalling

    Alarm or fault signalling is carried out, both for the user and the installer, via these two modes, which require no additional installation, only WEB registration: WARNING LIGHT ON BOARD UNE ZHERO S10 The “RED“ indicator light indicates the presence of an active alarm in the system.
