ok, doing a battery/solar test, this will take a week+
I have 412AH of Lithium (5260WH) and a 360W solar panel on a MPPT 100/30. The N2175 DC Compressor fridge is on and set quite cold (close to 0F freezer, 34F fridge). The Maxxfan is run much of the day and into the evening, usually on 30%. LED lights are getting light use. The furnace is switched on at around 62 or 63F when its getting colder than that late at night, as I'm sleeping in the trailer every night during this test. My phone is getting USB C charged at night, usually about midnight til around 10am.
When I'm done with this, I plan on posting some graphs from the Victron shunt and solar, showing the week or so of discharge and whatever it takes to fully recharge without shore power.
The last week or so, the solar has been outputting 650-730 WH a day, recharging the batt.
tonight at 8:20pm, I shut my solar controller off.
2024-08-19 8:20pm battery @ 96%
oops, solar decided to recharge battery this morning, i used the wrong 'off' setting, i guess. ok, restarting test.
2024-08-20 8:00pm battery @ 97% (its been a couple years since I reset the charge state, me thinks I should do that when I've fully recharged)
2024-08-21 8:00pm battery @ 84%
2024-08-22 8:00pm battery @ 74%
2024-08-23 8:00pm battery @ 63%
2024-08-24 8:00pm battery @ 52%
2024-08-25 8:00pm battery @ 40%
edit: I will be editing this post each day until the battery is deeply discharged, then cranking on the solar to see how fast it recharges.
Saturday update: its looking like Monday/Tuesday will be the best days this coming week for the solar recharge, both days the sun breaks through morning clouds around 10am. so after tomorrow evening, the battery should be at 40% or so, thats deep enough for me.
