Good day. I am looking to install an inverter and panels into my caravan. I have enough space on the roof for 3x large panels (+-500w panels). Ive been looking at victron for their modular type system but it is quite pricey. I have also been looking at UPS/power stations as an alternative just for like 2 lights, a fridge, tv and a router. I found this one UPS that has connectors that work with the normal panels with the mc4 connectors. Its called Lumo Powerall, it can handle about 1500w of solar and has a decent bypass feature. Im just curious can you connect these types of systems to an alternator as well?

I'm curious what the alternator would be doing in the system you're thinking of. E.g. Are you replacing the batteries? So instead of having a 12V battery feeding the inverter, you want to put an alternator?

Typically inverters state what power they can take in the INPUT, e.g. Petrol/diesel Generators, DC is usually batteries., Solar or Grid AC (Eskom), but in ALL cases, there are working parameters that the INPTUT source must meet (Hz, V min and max etc). I do not your an alternators specs, (how suitable or clean the power it produces is), to feed into an inverter, but i highly doubt a typical inverter can handle the power coming from al alternator effectively. 

Lastly, looking at the image below, it looks like it only wants AC or Solar in... The built in battery provides the DC voltage. So bot sure where you wanted to put the alternator?

Thank you for replying, I was wondering if you could use the alternator as a source of power to charge the battery while driving as an addition to the panels. So if I was driving at night, the alternator could slowly add some charge to the battery. It was just a thought I had, hadn't really done much research on it, my thinking was just to see if it can be done, even if only certain systems/inverters could actually use the power coming from an alternator. This is a very informative answer. Thanks again!
