To choose the SolarEdge inverter inverter that best suits us, whether for our home or for our company, we must take into account a series of issues that we summarize below.
Calculation Of Our Consumption
In order to calculate the type and size of the installation that we want, we need to know the consumption that we are going to have to make sure that we have enough equipment to satisfy said consumption.
As seen throughout the article, another element to attend to is whether our installation is going to be connected to the grid or isolated, since depending on this we will need one type of solar inverter or another.
Based on the consumption that we are going to have, we can guide ourselves to choose the inverter that has the power (kW) that we need. To do this, we must take into account the nominal power (the one provided by the inverter in normal operation), as well as the peak power (higher than the nominal, but for a short period of time). The power that we must choose for our inverter will be determined by that of the installation of solar panels, and must be above 75% of the peak power installed in the solar panels.
It can be pure sinusoidal, more stable and conducive to the use of household appliances or connection to the network (optimal for consumption in homes), or modified, allowing us to expand the devices that we can plug in, both in terms of consumption and power (ideal for water pumps or industrial equipment).
If You Have A Battery Charger
Depending on whether we are going to have a storage system or not, we may be interested in one model or another of photovoltaic inverter.
We refer to the ability of an inverter to convert the electricity from the photovoltaic modules into alternating current for consumption and we refer the best one that call SMA inverters. It is measured in percentage and the higher this is, the less electricity you will lose when converting the entire system (including switching, output filters and transformer).
Technical Characteristics Of The Solar Inverter
Before choosing the solar inverter for the photovoltaic installation that you are going to carry out, it is essential that you take into account its technical characteristics. Next, we will explain the most important ones.
Solar Inverter Temperature
The temperature of the inverters is one of the most important points to consider during your choice. This is because the maximum power and the time in which it can be delivered depend on the temperature.
To be more exact, the greater the flow of current, the higher the temperature supplied.
Within this technical characteristic of inverters, we must highlight other aspects:
- Standby consumption: Although the levels are very low, the inverters always consume energy, even when the house has not.
- In this sense, when the power is greater, so will the standby consumption.
- Operating voltage: The operating voltage is reflected in the output power, and, in inverters with 12V batteries, this reaches up to 1200W.
- For its part, the 24V inverter has powers from 2000W to 4000W, while the 48V inverter has powers between 4000W and 8000W.
- Maximum peak power: Refers to the starting power that the most demanding loads have, and a good inverter should support at least twice that power.
