Hi all - I have a shop and looking into investing into a solar system.
99% of the time I charge power tool batteries and run maybe 60w of shop lights on 110v.
Once in a blue moon I need to run my compressor for sand blasting - its a 3HP 220v, last time i calculates the start draw is around 45 and running about 20-25.
I have PLENTY of sunlight, maybe 10 hours so dont need that much on tap solar power, its primarily for recharging the battery bank.
Now ive been tossing between 12v and 24v, but def leaning toward a 24v system if a 12v will not work AT ALL (i dont mind if it struggles a bit).. but 12v would equal a LOT of amp draw on the batteries.
Now inverter specs, where do I start. as far as ive read a LF would be better / thoughts? I will be going with a split inverter for 110 and 240v..
currently Im planning on a 280ah 24v battery lithium bank, maybe 400w solar and an inverter - everything will be wired within 20ft - ie REALLY close to where i work.
Let me know your thoughts - thanks!
also - ill be using the 3.2v cell system, not a complete battery, so yes I would need 8 for a 24v system..
Just not sure whether HF or LF, and if I can get by with 400w panels for recharging (mainly be using 200w max), mostly 100w max-
should I aim for more panels?
Thanks
