Which projects is it suitable for?
It suits boutique hotels, multi-storey homes and high-consumption villas. In homes with a PV system, it carries the daytime surplus into the evening and provides backup supply through a compatible inverter during a grid outage. The number of modules and total capacity should be determined according to the daily consumption profile.
For correct sizing, the electricity bill and the list of appliances are reviewed first; then the storage capacity, inverter power and number of parallel connections are determined. If this order is not followed, the battery either falls short or turns into a larger investment than necessary.
Use in Antalya and Solar Nexo support
Humidity and salty air are common along the coast; IP65 protection is an advantage in this respect. Even so, the battery should be placed in a shaded, well-ventilated spot rather than on walls that receive direct sun. Solar Nexo determines the mounting point and cable route during the survey.
From supply of the product through project design, installation, commissioning and subsequent technical support, Solar Nexo handles the whole process in Antalya from a single source. You can download the product datasheet from this page.
