The HSI3000 Single Phase Hybrid Inverter is connected to  Feed in Tariff  in UK Property – one of the first hybrid solar inverters

Voltacon Power Conversion a pioneer in renewable energy has successfully received a micro-generation certificate for one of the first hybrid solar inverters. The inverter is connected to a 3kW solar array and 4kWh lead-acid battery bank at 48Vdc. The sequence of evenets are:

  1. The PV panels will charge first the vented tubular batteries which are connected in series (8 block at 6V each)
  2. The surplus power (when the batteries are charged) is fed back to the grid for 14pence per kWh.
  3. At night or when there is no sun, the batteries and grid will feed the necessary power to all the home appliances

 

The inverter mounted on the wall of the garage with the feed in tariff meter.

The inverters are compliant with European and British regulation for safety, electromagnetic compatibility and protection against island mode.

In the present project the inverter operates in hybrid mode and charges the batteries only from the solar panels. However, it is capable of working in off-grid mode supplying electricity to critical load in the event of a grid loss.

There is enough capacity to run the whole property off grid for approximately 24 hours. Thanks to LED lights supplied by Ledison Lighting, the total energy consumption keeping all the lights on is only 350watt.
