  • How much can Powervault 3 save me per year?

    Customers with solar PV panels save around 50% through self-consumption. Powervault can increase this saving to 70%. For home owners with solar panels and Economy 7 tariffs, this saving can be increased further to 80%. However, properties with high consumption during the day or during off-peak times, or customers with small solar systems, may save less than this.

General

  • Will Powervault 3 be compatible with my solar PV system and inverter?

    Powervault 3 can be either AC- or DC-coupled. Connecting your Powervault 3 system on the AC-side is very simple; Powervault 3 is compatible with all solar inverters and PV systems and is very easy to retro-fit to your existing solar supply. You can also connect your PV system directly to your Powervault 3 system, which enables you to take advantage of Powervault 3’s hybrid inverter.

  • What happens to Powervault 3 in a power cut?

    Powervault 3 automatically shuts down in the event of a power cut. This is because the system must comply with G83/2 regulation, which ensures all power inverter systems do not export to the grid during black outs (to prevent their electrocuting any engineers working on the damaged power lines). Powervault 3 will automatically reboot itself when grid power has been restored.

  • How will I be able to see if Powervault 3 is working?

    Powervault 3 has an intuitive LED display across its chassis, which indicates how much energy is stored in the system and whether the system is charging or discharging. Powervault 3 owners are also able to log-in to the customer portal to monitor their Powervault 3’s performance. The online portal tracks the home’s electricity consumption and records home electricity demand, storage, discharge and export over time.

  • Can I run my kettle or iron off Powervault 3?

    Powervault 3 has a 5.5kW inverter built into the system. Powervault therefore has a maximum continuous power output of 5.5kW.
