The brand new series ET, by GoodWe, is a three-phase high-voltage energy storage converter that enables enhanced energy independence and maximizes self-consumption through an output limit function and time-out shifts for reduced electricity bills. Covering a power range of 5 kW, 6,5 kW, 8 kW and 10 kW, the ET series allows up to 110% overload to maximize output power and has an Uninterruptible Power Supply (UPS) function in inductive loads such as air conditioners or refrigerators with automatic time switching less than 10 milliseconds, providing savings, independence and safety when out of order or in danger.

1. What is energy offset (net metering); 

Energy offset means offsetting the energy injected into Network energy from a power plant with the absorbed energy in the consumption plant of the autoproducer. It concerns a production station which is installed in the same or adjacent space with the consumption installation, which is connected to the distribution network through the same supply. In energy offset, the energy produced does not have to be synchronized with the energy consumed.

The terms and conditions for the development of production stations with energy offset were initially determined by ΥΑ ΑΠΕΗΛ / Α / Φ1 / οικ.24461 (Government Gazette Β '3583 / 31.12.2014), which was subsequently abolished and replaced by ΥΑ ΑΠΕΗΛ / Α / Φ1 /οικ.175067 (Government Gazette Β '1547 / 5.5.2017), which was recently abolished and replaced by ΥΑ No. YPEN / DAPEEK / 15084/382 (Government Gazette B '759 / 5.3.2019).

2. At what power limits is the development of power plants by energy offset generators in the Interconnected System applied?

In Interconnected System (mainland and its interconnected islands):

a) The power of each power plant can be up to 20 kW or up to 50% of the agreed power of the consumption plant (in kVA), if the last size exceeds 20 kW.

b) Especially for self-generating MTs as well as for self-generating stations regardless of the tendency of connection by legal entities of public or private law pursuing public or other public interest purposes, general or local scope, the power of each generating station can be up to 100% of the agreed power consumption.
