Here is the deal. Due to size issues, I have focused on a solar panel that meets my needs. As far as how many to buy and how to configure them is another matter. I am building a 24V system with the intent to have a 24V solar array, and battery pack. Am using a Victron 3000va 24/3000/70 Multiplus.
The manufacturer says the panels are 64 cell, but I was told they are really 32 cell. They then said to make them 24v compatible, I should put two in series, and then put the two-panel strings in parallel. Apparently, something about 64 cells is closer to 70 or 72 that is ideal for 24V? I hadn't heard about particular cell configurations being better for one voltage or another.
Originally, using a different BMS, he said I was maxed out at six panels. I don't know if a Victron SCC has such a limitation.
Without a hassle, I can make a string of 6 panels on one side of my TT, and another string of 6 on the other side. Since the AC, etc. are in-between, one set might have shading the other set doesn't have. Doesn't that suggest two SCC is best, one for each side?
1. Would a Victron 100/30 be a good fit for each set of six panels?
2. Would you configure them 2S3P?
Thanks for any ideas or suggestions given I think this is the panel I want!
BTW, I have written HQST/Renogy and haven't heard back.
