Hi, dears.
I saw one of the video that www. santansolar.com has used 250w solar panel for $50. it totally catch my sight and want to build a solar system for my shed.
the panel info is following
Rated Power: 250W
Open circuit voltage (VOC): 37.6 V
Max power voltage (VMP): 30.3 V
Short circuit current (ISC): 8.85 A
Max power current: 8.27 A
Power Tolerance 0/+3%
Maximum system voltage: 600V (UL)
Fuse Rating: 15 A
IP65 Junction Box w/MC4 Compatible Connectors
Frame: Anodized aluminum alloy
Weight: 41 lbs
Dimensions: 1650 × 992 × 35mm (64.95 × 39.05 × 1.37 inches)
First at all, i am planning to buy 10 of the solar panels
and buy 8pcs of 6 v batteries and wire them as the attachment.
my questions are:
1. What type of charge controller i need ?as i know 10 of panel means 2500w
it has {(37.6v * 8.85A) * 10}=3327.6watts/24V=138.65AMP so i need a charge controller over 140a and up, BUT,i can't find such charge controller at Amazon.com
ANY suggestion.?
2.as i want to build 24 V system, i need a converter, what large of converter I need.?
3. Can you figure out for me what else i need and what is your suggestion.?
Thank you for information
Very appreciate
