What is the best wiring diagram for my panels? I don‘t know where the number 10 came from. Note: solar power calculator assumes 12V solar panels are connected in parallel. James Ville 50% discharge has to do with capacity. A 7 Ah battery can generally be safely charged at 0.5 C or less (3.5 A). It says in block 29 I need just over 7 panels in parallel. 1-800-472-1142. I am completely new to all these conversions and solar panels etc. DIY wiring diagrams for 100W, 200W, 300W, 400W, 600W, 800W kits. Only enter data into the PALE ORANGE columns. I tried to use this calculator for sizing solar panels in hybrid system for micro GSM BTS, but size of invertor is too big for total load of 500 W. For total load of 500 W with operational time 24 h per day, calculator gives size of invertor about 555 KW. Thanks for catching that :). Erick I am building a small weather station 12V power system, and was trying to solve for hand calcs for number of panels, I saw there was a mention of line 29 was the total wattage PV over the size of panel. My background: I‘m doing an undergraduate project where I‘m building a PV powered Vapor Compression Refrigeration system. This calculator is meant for camper van conversions, RVs and small off-grid solar systems. The exact number changes depending on the specifications of the chosen panel model, as well as the sunshine available at the project site. Battery MINDer makes the SCC015, a very nice unit that also de-sulfates and restores batteries. 22 = 10 daylight (conservative 9closer to 12) I just can‘t get it figured. 12v x .29A = 3.48W Watt hours = 3.48W x 24 hours = 83.52Wh Determine Amperage Hours A= W/V Ah = 83.52WHr/12V = 6.96 Ah per day Step 2: Determine peak sun hours for your location. Determine how many solar panels you’ll need. Montagu, South Africa. Not sure how I came up so short. Please contact one of our techs at [email protected] I am using an 85 Watt panel providing about 6 amps. Does this mean I have too much charging current going to my batteries? Head to our electricity main page for further explanations of each solar panel component. BatteryStuff Tech Our recommendation is to discharge no deeper than 50%.
