Hello,
I have been reading this forum for a while now and am very thankful for all of you who are here sharing information. I believe that I am posting this in the correct place, forgive me if not. So here it is... I am actively designing an off grid system that I plan on purchasing over the next few months. I really want to do this right so I am asking for your guidance and experience in the design. I have experience with Lifepo4, inverters, chargers, bms, electrical engineering; so I wouldn't consider myself a beginner, however I also do not consider myself an expert. I completed an energy audit and determined that I will need between 450-600kwh per month. I live in south Florida and average 4.5-5 hours of sunlight per day. Wind generation isn't really an option due to the slow winds speeds here. We designed and built a very efficient Tiny house and have it currently running on a Honda 2200 generator on 22 acres. The only difficulty with off grid in FL is the requirement for AirCon, hence the need for 450-600kwh. So I would like to design a solar system to run everything most of the time.
Initial ideas:
Victron Energy Quattro 8K (either 240v or 120v depending on charging solution)
Custom Built Lifepo4 battery bank:
Ideas: Source (32) Amy supplied 280ah Lifepo4 cells for 48v 560ah (26,880wh)
Charging:
Either Fronius or Sunny 8k PV inverter (AC charging)
or
Victron smart solar charge controllers (DC charging)
*I am not decided here, due to the desire to still be able to use my Honda 2200 (120v) if needed
PV:
I live near Miami and they have a large panel supplier who routinely has 380-420 watt panels.
Please help me design this system correctly. I do not have a lot of experience with Solar panels yet, and dont want to overlook some solutions that I simply just dont know about yet. Thanks in advance.
