The solar inverter is the heart of any photovoltaic system: it converts the direct current generated by the panels into 230V alternating current, which is the type of electricity used by the appliances in your home, your van or your industrial unit. Choosing the right inverter determines the system\u2019s performance, its reliability and, above all, how much you\u2019ll be able to expand it in the future.<\/p>\n
The panels produce direct current at a voltage that varies with radiation and temperature. The inverter takes this current and converts it into a sinusoidal alternating current at 230V and 50 Hz. In a modern system, it also performs three further functions: it identifies the panels\u2019 maximum power point using MPPT tracking, synchronises the output with the grid where one is available, and manages the charging and discharging of the batteries if the system has them.
\nThat is why the rated power is not the only figure that matters. A 3000W inverter that cannot start a pump motor is worse than a 2000W one with good peak capacity. A pure sine wave, as opposed to a modified sine wave, is essential for electronics, motors and compressor-driven domestic appliances.<\/p>\n
Grid-connected or self-consumption inverters<\/a>:<\/strong> connected to the grid, without batteries. They supply the household\u2019s electricity needs and feed the surplus into the grid. They are the most efficient and the most cost-effective per kW installed. We are Fronius<\/a> System Partner and Official Service<\/strong> in Spain. Power is calculated based on the maximum simultaneous consumption, not on the total of everything you have plugged in. Make a list of everything that might be running at the same time during the busiest part of the day and allow for start-up peaks. If you\u2019re certain you\u2019re going to install batteries, a hybrid system works out cheaper and is neater than a grid-tied inverter to which you\u2019d later have to add a storage system. If, for the time being, you just want to reduce your bill but haven\u2019t ruled out batteries in a few years\u2019 time, a high-quality grid-tied inverter with a MultiPlus-II<\/a> Adding it later is a perfectly valid approach and allows you to scale without having to discard anything. There is no single answer, but there are criteria that matter more than price: the availability of spare parts, the quality of the firmware, technical support in Spain and the ability to integrate with third-party batteries. We stock solar inverters for all voltages and power ratings, ranging from 12V to 220V inverters for a van to high-power three-phase systems for industrial use. If you\u2019re unsure which model is right for your installation, or would like us to review a diagram before you make a purchase, our technical equipment<\/a> We offer free advice.

\nOff-grid inverters\/chargers<\/a>:<\/strong> for off-grid installations or those with an unstable mains supply. They incorporate an inverter, a charger and an automatic transfer switch. The Victron MultiPlus and Quattro ranges cover capacities from 500VA to 20,000VA in 12V<\/a>, 24V<\/a> y 48V<\/a>, and they can be connected in parallel and in a three-phase configuration.
\nHybrid inverters<\/a>:<\/strong> They combine self-consumption with the grid and storage in a single unit. This is the cleanest option if you\u2019re going to install batteries from the outset, as it avoids duplicating electronics.
\nIf you\u2019re simply looking to convert 12V to 220V in a van or on a boat, without solar panels or a charger, the category you\u2019re looking for is 12V to 220V inverters<\/a>, also available at 24V<\/a> y 48V<\/a>.<\/p>\nWhat inverter power do I need?<\/h2>\n
\nAs a practical guide: a 3000W inverter<\/strong> is suitable for a small home or a holiday home with basic appliances and no heavy loads. A 5000W inverter<\/strong> is the standard for a main residence with an induction hob or heat pump. From 10.000W<\/strong> We\u2019re talking about large premises, three-phase systems or commercial use, where the issue is usually resolved by connecting several units in parallel rather than using a single unit.
\nThe system voltage is linked to the power output: 12V up to around 2000W, 24V up to 3000W, and 48V above that. Increasing the voltage reduces the current and, with it, the cable cross-section and power losses \u2013 something you can check in our cable cross-section calculator<\/a>.<\/p>\nHybrid inverter or grid-connected inverter<\/h2>\n
\nIn both cases, you\u2019ll need to keep track of what comes in and goes out of the house: that\u2019s what the energy meters<\/a> and the systems for monitoring<\/a> such as the Cerbo GX, which also allow you to view the system remotely.<\/p>\nWhich brand of solar inverter should I choose?<\/h2>\n
\nWe work mainly with Victron Energy<\/a> in the off-grid, campervan and boating sectors, where its ecosystem is hard to match in terms of flexibility and documentation, and with Fronius<\/a> in grid-connected self-consumption, where the fact that they are manufactured in Europe and their service network make all the difference when something goes wrong. We have direct agreements with both manufacturers and hold stock, rather than simply acting as a distributor.<\/p>\nWe\u2019ll help you choose before you buy<\/h2>\n
