Thanks for the clarification, the reason I'm thinking about using 24V panels is they are much cheaper than 12V panels for the same wattage, for example a 12V 175 watt panel is $200 in my area, I can buy a 400 Watt 24V panel for $200. Yes, once I add in the Victron any savings are gone due to the cost of the victron, but I'm not sure if I'm going to stay with 12V for my Camper battery.
I been thinking I might decide to switch over to 24V in the future, because I have been thinking about getting a Small 24VDC Air Conditioner. If I do that it makes sense to switch over to 24V, since my Fridge Freezer can run on 12V or 24V. So I'm thinking that future proofing the design by having a 24 V panel may be a good idea
If I was 100% sure I would stay with 12V, then buying 200W 12V panels would make perfect sense
I have the LiFePO4 cells I got for free and have enough enough to make the switch to 24V if I decide to do that in the future, so no added cost for the battery cost to switch to 24V
If I make a sliding panel holder I can fit 2 of the 400W panels on the roof of my camper, one on top of the other, then slide the bottom one out when at a camp site. This might give me enough solar to run a small 2300 BTU 24V (250 Watt) Zero Breeze Air Conditioner for a few hours at night.
Thanks again
