I converted my 23 foot travel trailer into a home office and it works fine for now with a heavy duty extension cord to the 15 amp connection at the house. That will all change in the summer when I will want to run the air conditioner. My initial thought was to install a 30 amp RV hookup...

I was going to do them all in parallel as I want to use a 12 volt battery and inverter I already own. Having said that, is it possible to get a MPPT charge controller that has 24 volt input and 12 volt output so I can put panels in series?

A full power audit is tricky. If I build an off grid system I would need to plan around worst case circumstances which would include running the AC. I cannot run the AC without sinking a few thousand into the RV hookup. If I am going to build an off grid system anyway, I would rather not sink...

Would it be better to make two series arrays and connect them in parallel or two parallel arrays and connect them in series?

That is very helpful. Thank you.

I am looking at the Bluetti AC300 with the 150 volt input max. I like this solution because it is just plug and play. I don't like the foldable panels though from the same manufacturer. I get that 150 volts input capacity means you can use other panels in series up to 150 volts and they list...

Yes, the I have 6 panels on order at 320 watts 40 open volts each. So 3S2P sounds like the way to go. Do the OCPD fuses then go at the positive end of each series array? I am not clear on where best to put those? Also what size fuse for the OCPDs?

I am looking to buy a charge controller that will handle 4 panels, each panel with the following specs: Open-Circuit Voltage (Voc): 24.3V Short-Circuit Current (Isc): 5.21A Maximum Series Fuse Rating: 15A There is obviously a big difference between a charge controller rated for a ~500 Watts...

I have 6 panels on order at 320 watts 40 open volts each looking into series parallel combination as charge controller is 150 volt max 2400 watt max. Do the OCPD fuses then go at the positive end of each series array? I am not clear on where best to put those? Also what size fuse for the OCPDs...

From the product specs: Specifications Maximum Power: 320W ULOpen Circuit Voltage: 40.1Maximum Series Fuse Rating:15A Short Circuit Current: 10.08A So I am inclined to get 15 amp fuse based off of the "series fuse rating" but the "short circuit current" is 10Amp so thought perhaps I needed 10...

Thanks for the feedback all.

Thank you for the reply. Follow up question then, is there a reason not to add/remove a panel from the series array based on the season? My thought process is to buy more panels than needed as I have other out buildings I will also need panels for in the future, but build this array such that...
