Setting up a 500-watt solar system to power a 6000 BTU inverter air conditioner (AC) using an Eco-Worthy 280Ah LiFePO4 battery and a Renogy 40-amp MPPT charge controller is a practical and efficient approach to off-grid cooling. Here’s a comprehensive guide to achieve this setup:
Components Overview:
Solar Panels: A total of 500 watts, typically comprised of multiple panels (e.g., two 250-watt panels or five 100-watt panels).
Battery: An Eco-Worthy 280Ah LiFePO4 battery, known for its long cycle life, safety, and efficiency.
Renogy MPPT Charge Controller: A 40-amp MPPT (Maximum Power Point Tracking) controller to optimize the power harvested from the solar panels.
Inverter: Required to convert DC from the battery to AC for the air conditioner.
System Efficiency and Management:
Energy Consumption: A 6000 BTU inverter air conditioner typically consumes around 200-600 watts, depending on efficiency and usage. Assuming the AC runs for 15 hours a day.
Battery Capacity: The Eco-Worthy 280Ah LiFePO4 battery provides 3.36 kWh at a 12V system voltage, covering daily usage but requiring good sunlight to replenish fully each day.
Solar Output: 500 watts of solar panels can generate about 2.5 kWh to 3 kWh of energy on a sunny day, depending on location and conditions.
Balancing Load and Supply:
Peak Sun Hours: Maximize energy collection by ensuring panels receive peak sunlight for as many hours as possible.
Backup Plans: Consider a generator or additional solar panels for prolonged cloudy periods to ensure uninterrupted cooling.
By following these steps and considerations, you can create an efficient and reliable solar power system to run your 6000 BTU inverter air conditioner, ensuring comfort and energy independence.
We installed an EG-4 12k btu 28.5 Seer-2 mini split on the rear of our 35ft motorhome. Its super high efficiency means it produces about 3 times the cooling power for every watt of power it consumes compared to a 9.5 ceer window unit and about twice as efficient as an inverter powered window unit like you have. Plus, it's the perfect size to cool a small to medium travel trailer like you have. I paid $1,500 for it last November, but this same exact unit is on sale now from Signature Solar for only $1,350. I'm 67 yrs old and installed it myself from the instructions, as its plug and play - no charging or flaring of tubing needed. I can run ours 24/7 as we have a large solar/battery system. It ramps up and down only using the power needed to cool rather than turning itself on and off like most A/Cs do. Ours typically uses between 450-600 watts during the day when the sun is shining and drops to around 200-350 watts at night. We are FTers who boondock most of the time. In fact, we boondocked for 10 month last year, so use it every day for either cooling or heat, saving us money on propane too.
Nice setup. yeah mine uses around 250 to 400 watts during the sunny days and around 100 to 200-watts during the night. I love it for its size as it will cook up to a 24ft RV. Any bigger than 24ft. and you really need to use a mini split.
@@familyrvliving if your unit only uses 250-400 watts then the ecoflow ac unit would absolutely cool your RV because 400 watts is equivalent to 4000btus and the ecoflow was 5100btu output.
you shouldn't judge the AC unit based on the Seer rating number. I think window units are more efficient than you are claiming. 300 percent cooling to watts ratio is normal for air conditioners, imo.
@@uhjyuff2095 true, the ecoflow is rated at 5100 btu of cooling power, but it creates a ton of loss because of the way the cooling power is transferred through those tubes, so the real world cooling power is much MUCH lower. You can see this loss because everyone that uses the ecoflow can only cool a van.
Those units can't even cool a small 18ft. RV. But LG's 6000 btu inverter window air conditioner has an efficient design to exhaust the heat. This means that my 6000 btu LG inverter air conditioner can easily cool my 18ft. RV. The proof is that I can actually do this, where the proof is that ecoflow's unit can only cool a van. You can see a bunch of TH-cam videos supporting this data.
@@uhjyuff2095 This is true because window units can exhaust the heat more efficiently.
The AC is $300 but you forgot to add the cost of generator.
The generator is a power smart 1500 watt for $250. It’ll run your ac and still have enough power to recharge your batteries
I have a breakdown of all the costs on my website.
