Planning to upgrade my trailer. Trying to decide which voltage system I should go, 24v or 48v?
* I have 2x 220w solar panel (19.7v 11A, https://lumerasolar.com/product/220w-bifacial-12v-solar-panel-canadian-made/). I'm planning to get 4 additional same ones. This will be the max I can fit on my roof.
* Planning to get all in one system like MPP 3048lv-mk.
* Have one 12v 100Ah LiFePo4 battery, but planning to get larger battery and repurpose the 12v battery for other use.
* Trailer is 2022 model and came pre-wired for solar.
* I can get very good price on solar panel and MPP 3048lv-mk.
* I'm also planning to get a connection to my house from the trailer. So when the trailer is not being used, I can still take advantage of the system in the house.
If I go with 48v and 6S configuration, the voltage will over the max for MPP 3048LV-MK (115v). For 3S2P configuration, the voltage will below the min voltage (60v).
Also given it is a travel trailer and will be parked in the campsite which may have shade quite often, should I go with 2S3P configuration for more redundancy? Then I will have to do a 24v system.
Any suggestion? Thanks!
