Cyprus-based Ratherhon has developed a smart zero export control device that prevents PV export losses from being exported by limiting generation to self-consumption. Certification will be expected soon.
The Cyprus-based renewable energy company Righthon has developed a smart zero export control device that prevents PV export losses from being exported by limitation and at the same time protect system owners against wasted generation.
Dublynchronized Elpida, the product is expected to secure the certification in the coming months.
“The Elpida devices have been developed to reduce the energy losses of houses and companies from wrinkled limitation of PV systems in Cyprus,” the company told PV -Magazine. “It is installed at the PV system location, receives a signal from the distribution system operator, measures the load and arranges the inverter dynamically to prevent energy exports.”
According to the company, households in Cyprus are expected to lose around € 300 ($ 350) in 2025 due to the limit of wrinkle. In those situations, the distribution system operator sends a wrinkle signal to inverters and ordering them to limit production to prevent grid transfer. However, because self -consumption does not disrupt the grid, the new product allows it to dynamically arrange it by the inverter.
The supply of the device is 230 VAC to 270 VAC and can read three phases between live and neutral (L1-N, L2-N, L3-N). It works with no fewer than three current transformers and can be performed internally at 12 VDC, 5 VDC or 3.3 VDC. It communicates with inverters via the RS-485 serial communication stand.
“We study other EU countries where limiting the roof systems leads to considerable losses,” the company added. “Our provisional findings show that in the United Kingdom, Germany, Spain and Portugal, the distribution system operators are implementing zero injection modes.”
At the beginning of 2025, Cyprus limited more than half of its potential renewable power, including record housing zones, as grilles and a lack of storage.
According to Cyprusgrid, an energy analysis platform concentrated on the electricity sector of the country, Cyprus restricted 145,000 MWh of renewable energy between January and May 2025 – an entry rate of 58% on an estimated 251,000 MWh of potential clean generation.
Cyprus, on the other hand, limited 29% of the generated renewable energy in 2024, an increase of 13.4% in 2023 and 3.3% in 2022.
