Still trying to figure out how to proceed with my solar adventure :). At the moment I got 2 x 300W panels connected to an Epever MPPT (https://www.amazon.se/EPEVER-solladdningsstyrenhet-litiumbatterier-identifierande-systemspänning/dp/B07FRM17DM looks almost like mine except that mine has got...

Thats what I meant, some days it will only make 5kWh, thats what I would need in winter. Of course, in summer it would be much more ... thats what I am trying to figure out, what happens in summer when it makes a lot more ... will the energy just be lost if I only had a 5kW battery or will...

Thanks for all your ideas guys! Little example to see if I got the math correct: Lets say I need 5kWh a day in winter. Would I need panels that sum up to ~25kW so I get enough in winter? If so, which equipment would I need? Is a battery with a capacity of 5kWh (like the Growatt APX 5.0P for...

Alright, so those 3600kWh depend on the amount of panels so to say ... got it, just the number without knowing the amount of panels is useless. Thanks!

In my region (in Sweden) the winter months are quite dark, there is some sunlight, sun goes up at around 9am and goes down at around 3pm. I used a calculator which said I can produce 3600kWh a year in my region using solar panels. Just for my understanding, can I not "get" more solar power from...

Thanks for the answer. Why would I want to increase the voltage?

I get it, what would be the advantage of putting them in series compared to parallel? When I put the batts parallel, will they last 3 times longer when they are loaded? So if I get 3 hours of running time with my devices, will I get 9 (more or less)? Thanks :)!

I am all new to the solar world. In my cabin which I just bought I have 2 300W panels = 600W. At the moment, these are connected to a 12V | 80Ah car battery. I was wondering if its somehow possible to charge multiple of those batteries by putting more batteries in series. What I want is to...

Thanks for all the answers ... I checked the price of the inverter I have and it seems to be one of the cheaper ones. I think Id go for one with passive cooling :-). Thanks!

Thanks for your answers ... its not only about the laptop, the fan starts running even after switching on 3 normal room lights which might have 50W together. I am only wondering why it happens so early ... I mean if it started at 500W, ok, but after about 1/10 of the W it supports? So again...

Thanks! Could you guys recommend a good inverter? Mine is a ProPlus, does not say much more on the cover. It looks like it wasnt the most expensive though :-D.

I just bought a cabin which has 2 solar panels with 600W together (300W each). My inverter has 600W continuous power and 1200W peak power. The inverter is connected to a 12V 80AH car battery. As soon as I plug my 45W laptop in (nothing else connected), the fan starts blowing like crazy. The...

Yes, that makes sense, thanks for your answer!

Thanks folks, all clear now :-)

When looking at solar setups on Youtube for example, people always have the MT50 almost next to the Mppt ... what I understood is that the MT50 is some sort of a remote control for the Mppt? Is it really just that, or why do people almost always have the MT50 next to the Mppt? Thanks for...

When I press "ENTER" on my Mppt, there is the moving arrow on the right side to the direction of the light buld (). Logically I would say this means that some device is taking power from the battery. Question is, what happens when I have devices connected to the battery / inverter and press...
