Hi Agustin,
All in one units like the one you chose is find for house, maybe even an RV. For a variety of reasons some obvious some not, an actual marine rated rated inverter will serve you better. Probably more expensive but may be worth it. Look into Victron.
Look at the specs, on your inverter. The minimum solar operating voltage is 120. You will have a very hard time achieving that on a your boat.
I have not yet seen a use case where CIGS make sense. Better shading performance maybe but it will almost certainly not make up for its much lower overall efficiency.

Sorry, I missed the untranslated version…
I don't know exactly how the solar inverter works, but it is charging a 48v and 320ah battery bank.
I don't know why it's called a solar inverter, or they sell it under that name. But in reality it is a 48v MPPT Charger + Inverter 48v dc to 120v ac.
And it has the ability to select what is the preferred source of energy, it can be the external network, it can be the energy of panels, or it can be the batteries.
I don't know if anyone else tried to use this type of equipment on boats, I usually see that they have everything separately.
I chose this one, because it gives me the option of connecting a generator or an external power source without having to modify any switch. He will manage the energy transparently, or so I hope so.
Everything is in the development stage and I still don't have all the parts to try it...
I would also like to know about solar panels, because at the moment I saw as a good option the CIGS panels that have less loss due to shadow, but are more expensive.
And on the other hand, I can't find panels that publish them because of their size, something that is too important on a sailboat.
Most say 100w or 200w and then you have to check the sizes within each publication and that makes it quite difficult.
I was thinking of drawing the surface of the sailboat and starting to calculate what the best distribution will be.
The number of panels you place will be the maximum capacity you can.

No se perfectamente como funciona el inversor solar, pero el mismo estára cargando un banco de baterías de 48v y 320ah.
No se por que se llama inversor solar, o lo venden con ese nombre. Pero en realidad es un Cargador MPPT de 48v + Inverter 48v dc to 120v ac.
Y tiene la capacidad de seleccionar cuál es la fuente preferida de energía, puede ser la red externa, puede ser la energía de paneles, o puede ser las baterías.
No se si alguien mas probo utilizar este tipo de equipos en barcos, por lo general veo que tienen todo por separado.
Yo elegí este, por qué me da la opción de conectar un generador o una fuente externa de energía sin tener que modificar ningun switch. El administrará la energía de forma transparente, o eso al menos espero.
Todo se encuentra en etapa de desarrollo y aún no tengo todas las partes para probarlo…
También me gustaría saber de paneles solares, por que por el momento vi como una buena opción los paneles CIGS que tienen menor pérdida por sombra, pero son más caros.
Y por otro lado, no logro encontrar paneles que los publiquen por su tamaño, algo que es por demás importante en un velero.
La mayoría dicen 100w o 200w y luego hay q verificar los tamaños dentro de cada publicación y eso lo hace bastante difícil.
Estaba pensando en dibujar la superficie del velero y empezar a calcular cuál será la mejor distribución.
La cantidad de paneles que coloque será la capacidad máxima que pueda.

I don't think that solar inverter is going to work very well in your situation. Its needs at least 120v from solar in order to work. You would need something like 6 flexible panels in series in order to hit that voltage or 3-4 66 cell rigid panels in series. Even if you could fit that on a 31' sailboat, you would have issues with shading.Best to find a high voltage panel- above 65v (which is not easy find) and use one dedicated mppt controller per panel or use one boost mppt controller per panel if the panel voltage is below 48v.Matt FoleySunlight ConversionsPerpetual Energy, LLC201-914-0466On Wednesday, October 5, 2022 at 10:53:22 AM EDT, twowheelinguy via groups.io <twowheelinguy=yahoo.com@groups.io> wrote:I would consider several smaller inverters that are dedicated to different loads on your boat rather than one big inverter for everything. For example, I have a 3000W high end Outback inverter for my house power and two dedicated cheap 3000W inverters for my aft and forward A/C units. This distributes the loads so that none of the inverters have to work that hard and you don't have to worry about tripping the breaker if the AC is running while you're making coffee and you put something in the microwave. And, if an inverter fails you have plenty of backup because any one of those inverters could run the whole boat in a pinch with careful load management. You can get a good, no frills pure sine 3000 Watt inverter these days for about $300 bucks. With multiple smaller inverters, you don't have all your eggs in one basket.Admittedly my system is a little extreme but you get the point.Capt.
