Single-phase self-consumption inverters convert photovoltaic output into 230 V alternating current for homes with a single-phase supply, which is the case for the majority of residential properties in Spain.<\/p>\n
The limit is set by your electricity supply, not the inverter. With a single-phase connection, the standard maximum contracted power is around 10\u201315 kW, and the photovoltaic system must fall within that range.<\/p>\n
From there, converting to three-phase power isn\u2019t just a matter of changing the inverter: it involves requesting a change in supply from the distribution company, with the associated costs and lead times. If you\u2019re planning to expand \u2014 heat pump, electric vehicle, workshop \u2014 think about this before you set up.<\/p>\n
We are working on the range Fronius<\/a> Primo GEN24 from 3 to 6 kW. The choice is determined by the ratio between the peak power of the panels and the inverter \u2013 which should be kept between 1.1 and 1.3 \u2013 and by the simultaneous power output you need to cover.<\/p>\n
