I’m considering a modest “off grid” trailer for use at 6-7 race events per year for vintage motorcycle road racing.
assuming no power available trackside(normal), I’m contemplating something like:
4 Rolls 6volt L16 batteries in 24volt configuration.
3 Longi 310 watt solar panels
1 all in one Hybrid solar converter/charger of suitable capacity
my events generally require 3-4 overnight stays in the trailer(6x14, moderately well insulated) and often hot days with some hot evenings and occasional cold evenings. Worst case scenario is 85 degrees plus with humidity overnight. Most events are 10plus hours drive from home.
FWIW, I’m primarily of northern Scandinavian decent, and my body reacts poorly over 85 degrees. In high heat I sweat at a ridiculous rate while most people are far less effected. Cold weather, no problem. It’s a common theme with my extended family.
so I’m lookin at a modern inverter type air conditioning unit at 8000btu.
specifically a Midea U MAW08 VIQWT
A technical reviewer reported it consumes on various settings
530 watts at 8000btu
380 watts at 5800btu
285 watts at 4300btu
190 watts at 2800btu
160 watts at 2400btu on its lowest setting (and near silent)
As reference, an experiment I read showed a 24 volt bank of 4 used Trojan L16 320@5hr batteries ran a 2012 vintage Kenmore 253.79081 8000watt window AC on full power for 4 hours off a Xantrex 1000 watt sine wave inverter using 550 watts continuous and reported to consume 30-35% of battery power, and elected not to run it down to 50%
I’m assuming at night, bringing 85 degree OAT down to 70-72 degrees will consume on average closer to the 190watts at 2800btu(greatly depending on quality of insulation). If …that is the case, I should be able to run the AC for around 12 hours off a bank of 4 fully charged Rolls 6v batteries at 24 volts and be only down 30-35 percent from full. Sound reasonable?
I’m hoping the 930 watts of solar can produce around 650-700watts in reality mounted horizontally on the roof of the trailer on a sunny day. Even if the AC consumed 380 watts for 5800btu during the day, the 650-700 watts of solar charging should easily handle this and recharge the batteries to full again by night fall. With some power to spare I’d hope.
Am I in the right ballpark here?
