#Solar power converter manual#

This electric current is known as direct current.Īfter the energy is generated, one of the following things happens: These electrons travel between the positive and negative layers, which generate an electric current. The solar energy then runs around and makes the electrons lose. The function of these layers is to absorb the light that falls on them and then transfer this solar energy to what is called the photovoltaic cells. These layers are made of positive and negative layers connected via a junction. The sun falls on the solar panels or the photovoltaic cells made with semiconductor crystalline silicon layers. Let’s break down the working of the solar inverter for you. Generally, all the home appliances work on AC (Alternating Current) and not on DC (Direct Current), so the solar panels change the DC output that the solar panel collects. The solar inverter takes the variable direct current from the solar panels and changes it to an alternating current. There are numerous inverters used in solar panels. A solar inverter transfers the energy output derived from the solar panels to a usable form of electricity, which can be used commercially. It’s a very important BOS or balance system in a photovoltaic system that allows AC-powered equipment. It converts the variable DC or directs the current output of a PV solar panel to a utility frequency AC or alternating current, which is used by an off-grid electrical network or commercial electrical grid.

Check whether the inverter’s total maximum AC-capacity is not higher than 10 kW for a 3-phase inverter, connected to a 3-phase interface.Īre you still having problems with finding what causes your inverter to shut down? Please contact our Aftersales team at +31 (0)88 88 80 320 or by our contact form.A PV inverter or a solar inverter is a kind of electrical converter.

Replace this situation with a 3-phase inverter, or by three 1-phase inverters, that are each connected to a different phase.

Is your installation a three-phase with one or two inverters?.

Connected to a single-phase or a three-phase connection.

Check whether the total maximum AC-capacity of the inverter is not higher than 5 kW, for a single-phase inverter.

It can help to switch to a 3-phase connection with a 3-phase of the divide inverter capacity, even though the capacity of the installation is not bigger than 5kW (advisable).

Is your installation connected to single-phase?.

We advise to keep a voltage drop of a maximum of 1%.

As an installer is it wise to look at the settings in order to prevent the inverter to be set-up incorrectly.

Are the shut-down parameters of the inverter set-up the correct way? The inverter should shut down automatically as soon as it reaches 253 V.

The inverter is connected to the phase with the highest voltage.

The allowable voltage in the connection cable of the inverter is being exceeded, because the cable is too thin.The voltage in the residence is already too high (more than 240V).When the voltage is too high, the inverter shuts down automatically for safety reasons. High voltage outlet inverterĭoes the inverter shut down (several times) during the day? This is mostly due to the level of voltage from the outlet of the inverter. If you are not able to fix the failure, you can always ask our Aftersales team for assistance. You or your installer can fix these failures.

If this is the case, you can read the error message from the display and with the help of the manual you can learn what kind of error it is. In the event of a failure in the PV-system, the inverter will give an error message. This is legally bound and written down in several standards that the inverters should meet. Whenever there is a power outage, the inverter automatically shuts down. At the right moment, the right phase, the inverter will inject the electricity into the grid. The inverter is constantly measuring the frequency and the voltage from the grid and adjusts the generated power to this. This is due to the following: the electricity generated by the solar panels is temporarily stored in the inverter. Therefore, the inverter shuts down automatically for safety reasons. Whenever there is a power outage or when the inverters’ regulator and/or earth leakage switch is turned off, the inverter does not receive any electricity from the grid. This is a situation that can appear in the winter, during dark and cloudy days. As soon as there is enough light to generate power, the inverter will start automatically. In case of sunset, clouds or when there is snow laying on the solar panels, the system will not generate electricity because there is no light. The inverter is connected to the solar panels that only generate electricity by daylight. In this FAQ we explain when this can happen and why it happens. Consumers often ask us why an inverter shuts down.
