Agreed. I plan on 4s2p then 4s3p.

As mentioned in my prior post , my original plan (which is up and running) involves 8 100w HF solar panels w/sae to MC4 adapters w/15amp fuses each to a 50ft MC4 10awg cable(w/ a breaker box) to my Renogy 100a CC to 4 Weize 100ah agm batteries in parallel to bus bars & T fuse to a Renogy...

Once I find those panel specs , I'll post them. For some reason Harbor Freight doesn't list them in their manual. I've noticed that other people have had a hard time finding that info. I'll check on the panels tomorrow. I thought using 6 batteries and changing to 12 or 16 panels was a big deal...

I don't plan on running anything DC so I am not using bus bars. Am I wrong?

Your both are absolutely correct. My original intent, approx. 4-5 years ago, was to have a small emergency solar backup if I lost grid power to handle the bare basics, 1-2 100 watt panels with 1-2 100ah agm batteries. I'm sure I'm not alone in thinking if I just add a little bit more I can...

I keep changing my plans from simple backup to something more. . I now have 8 100 watt HF panels, Renogy 100a Charge controller & Renogy 3000w inverter. I have SAE to MC4 adapters so I didn't cut the connections going to MC4 10awg 50ft cable in 1in pvc. Thinking of doing 4 more panels in...

Also, I have 1inch PVC feeding the MC4 cables to a closet from outside. I have a plastic shelf which I plan to store the Charge Controller , Inverter and the 4 AGM batteries on the bottom shelf. Do I need to ventilate the closet? I was considering putting a vent on the door. I also will have a...

Thanks for responding! Renogy 100A 12V/24V/36V/48V DC Input MPPT Solar Charge Controller. In late fall thru winter in Wisconsin Sunny from 8am -1:30pm & 2-3pm, otherwise mostly sunny. Two Eco-Worthy 4 panel brackets facing south mounted side by side on cemented 4 by 4 posts

The closet won't have anything else in it so it won't be tight in there. I'm there most of the time working virtually so I can keep an I on it. Thanks for the input
