3.Economical, Sustainable, and Eco-Friendly
No fuel use, low maintenance, and zero environmental impact thanks to solar energy.
Off-grid systems operate completely independently; no grid connection is required. Energy is generated by solar panels, stored in the battery and made available through the inverter. In grid-connected systems, excess energy is given to the grid and taken from there when it is deficient.
Yes, they do. Systems such as the Plus Series 7.2 kW can easily meet the daily energy needs of small and medium-sized households. For larger businesses or farmland, our F Series 15 kW or 20 kW solutions are recommended.
No, it won't. Batteries store the energy produced during the day and switch on at night to operate the system. In addition, thanks to the generator integration, the system can be supported in emergencies.
Yes. As CW Enerji, we offer free exploration, technical consultancy and authorised installation services specific to projects in Romania. Just fill out the offer form for details.
