Thanks Chuck! From: AF <[email protected]> Date: Saturday, November 7, 2020 at 5:41 PM To: AnimalFarm Microwave Users Group <[email protected]> Subject: Re: [AFMUG] Solar calculator? 30 watts * 24 *14 = approx 10 kWh. So you need a 10 kWh battery. 10 kWh/48 = 210 Ah 48 volt battery.
Now, I have lotsa experience at my latitude and weather. I will take a stab at your situation. If you can easily get a generator to the site it makes a huge difference. I would say you need a minimum of 300 watts of panel which is not much. You can get one single panel of that size. Depending on the type of charge controller you use, you will probably want 2 or 3 panels to get the voltage up in the 60-100 volt range. So take a look at the MMPV of the panels you choose and add them up in series. Take a look at the max input voltage of your charge controller. Try to get the series voltage of the panels close to that max input voltage if you can. I promise it will work if you do 600 watts of panel, that would be at my latitude, middle of winter with snow and storms. 20X the load is my rule of thumb here for off grid. 20X the load and 2 weeks of battery autonomy saves you from expensive helicopter rides in the middle of winter. So that is why I am recommending 10X for you. I think Bill once said he can get by with 10X down where he lives. From: Gino A.

Or can you assits with: What size of panel and batteries would I need for a 48v 30W setup to run 24/7 for at least 14 days without power?
