Grid-connected MPPT micro-inverter

1_3005bee5-3820-450e-8780-7570f3910327

Micro inverters, also known as small inverters, are inverters with a relatively low power. Compared to regular inverters for household or commercial applications, the power of micro-inverters is typically below 1kW, making it more suitable for light-load applications.

Higher conversion rate

A single inverter is responsible for each unit. Higher conversion efficiency than traditional string inverters! Bring you a higher solar power generation experience

safer

Traditional centralized inverters or series inverters usually have a DC voltage of a few hundred volts to a few thousand volts, which is easy to catch fire and difficult to extinguish in the event of a fire. Microinverters are only a few tens of volts DC and are fully paralleled, minimizing safety risks to a large extent.

MPPT tracks the maximum efficiency point

Module-level MPP tracking, no socket effects, reduces the impact of shading on power generation; Good low light performance as the starting voltage is low at only 20V and it works even in low light.

Longer lifetime

The low power of micro-inverters has little impact on the power grid, so they can be easily connected and meet the various needs of power grids.

Normally, the service life of the control cabinet inverter is around 10 years. Microinverters can last up to 25 years

Practical and aesthetic

No dedicated switch room is required, microinverters can be installed directly behind the modules or on the trusses. Because they are connected in parallel, more inverters can easily be added later to increase the size of the installation, without changing the previous configuration.


Gift socket interface, plug and play. Easy to install

What Is MPPT Technology?

MPPT is the abbreviation for Maximum Power Point Tracking.

MPPT is the abbreviation for Maximum Power Point Tracking.
MPPT technology is a key technology in photovoltaic solar energy systems. Due to the fact that the output characteristic of photovoltaic modules does not match the input characteristic of the load, the system may not be able to output the maximum power. MPPT technology can track the maximum power point of the photovoltaic modules, allowing the system to achieve maximum power output.

The basic working principle of the MPPT is to seek the maximum power point by converting the output voltage and current of the photovoltaic panels. Common MPPT algorithms are:
1. Incremental conductance: Finding the maximum power point using the "slight perturbation" method.

2. Fit curve method: Creation of a power curve based on the output characteristic of the photovoltaic modules to predict the position of the maximum power point.

3. Equivalent load method: Continuously change the equivalent load of the photovoltaic modules to search for the load point with maximum power output.

4. Humidity Method: Simulating the flow of water downhill to search for the maximum in the direction of increasing power.

5. Neural network: Use of the self-learning and optimization function of neural networks to search for the maximum power point.

The MPPT maximizes system efficiency and has an important impact on system performance. Used in photovoltaic inverters and photovoltaic charge controllers, it is the key to highly efficient energy conversion. Currently, digital-based MPPT algorithms and controllers are widely used in micro-inverters and photovoltaic systems.

In summary, by following the power output curve of photovoltaic modules, MPPT technology optimizes the search for the maximum power point to achieve maximum system output power. It is widely used in micro-inverters and photovoltaic power plants.

Solar-Netz-Wechselrichter, 300 W läuft und leistet

Ich war ja erst einmal skeptisch, Weil der Preis so niedrig ist. Niedriger als die der gleichen Spezifikation auf dem Markt aber bislang - das Gerät ist nun 3 Wochen im Einsatz - bin ich wirklich zufrieden.

Die Installation war einfach, die beiliegende Anleitung ist ok. Wie und wo man es am 230V-Netz anschließt sollte man wissen.

Die Kabel könnten insgesamt etwas länger sein, bei der Montage braucht es schon etwas Platz, auch das 230V-Anschlusskabel ist recht kurz. Der Wirkungsgrad scheint zu passen, mit 36V-100W-Zelle zeigt das Wattmeter bei voller Ausleuchtung als 230V Ausgangsleistung 90,8W an, also im Rahmen der Messgenauigkeit wie erwartet.

Ein wenig irritierend war der Wiederanlauf des Wandlers. Wird er vom Netz getrennt, springt er nicht wieder an, bis die Solarzelle einmal getrennt wird. Allerdings hat mich meine Geduld nach 15 Minuten verlassen, möglich dass der Wandler nach längerer Wartezeit oder sonst über Nacht wieder von selbst anspringt. Aber nun, wenn das Gerät läuft muss man ja nicht mehr so oft an die Leitungen heran.

Die Betriebsgeräusche beschränken sich auf ein leises Summen, warm wird der Wandler nicht, bei 100W ist er ja auch noch nicht wirklich ausgelastet. Zumal die Sonne nur selten mehr als 30W bringen wollte. Betriebsdaten liefert das Gerät bis auf die rot-grüne Betriebsanzeige nicht, aber das ist bei dem Preis auch ok.

Alles in allem kann ich das Gerät jedenfalls empfehlen.
