    Hi, an update if you're still interested. I decided to go with the Growatt 48 V system with 2000 watts of solar panels on the roof and 4 100 Ah Battle Born lithium batteries. The batteries were expensive, but you can't argue with the warranty and come with their own BMS. I ordered...

    Now, that's an idea to look into! Thanks!

    It's amazing that for something that in theory is so simple, just how complex it can get once you go into the weeds a bit! I suffered a really bad flair up of my sciatica, so was side lined for several weeks. Then there was a death in the family that required my attention out of town, so my...

    Wow! Thank you very much for your reply! Unfortunately, we had a family celebration and I had a couple, so I'll have to revisit your ideas in the morning! I was particularly appreciative of your point about removing the converter...I just replaced it because the old one was bad and I just...

    Congrats on getting ready to pull the trigger on your new system! It's amazing how far into the weeds that you can get with this stuff! ;-) Our situation is that my wife is retired and I'm going to be working part time from the road. We plan on taking several extended RV trips per year...

    Hey Chris: I watched the video and came away with a few observations. The first of which is that we're going to be running 2000 watts of solar. So, a bit over 3 times as much as this guy had. We're starting with the same 4 100 Ah batteries, but when we add the second back of 4 100 Ah...

    Hi, My wife and I just bought a 2002 Fleetwood Terra Class A motor home that we plan on going boon docking for extended periods of time. Sometimes it will be in hot, muggy environments. So, I want to build a system that could eventually run the AC off of the batteries. After watching Will's...

    I've thought a little bit about it, but haven't really researched it yet. Have you looked into it already and if so, what did you find out?

    Hi, I hope that you guys don't mind me jumping in on your conversation, but it looks like I'm in a very similar position to Carl in that I'm wanting to put a solar system with lithium battery backup for my 31' Class A motor home. My goal is to be able to boon dock in a hot environment and to...

    Hi Guys! I got distracted and posted the following post to a different thread, but I didn't want to leave you guys hanging...so, here is that post. Please let me know what you think! Hi, I hope that you guys don't mind me jumping in on your conversation, but it looks like I'm in a very...

    Hi Chris, thanks for replying to my post! I just posted the specifics on the system that I'm thinking about. With the mini-split (which won't be pulling the 1260 watts continuously, but rather something less) I'm shooting for being able to run my ac for 8 hours without firing up the generator...

    Hi Joey: My biggest concern is to be able to run the AC off of the batteries for at least 8 hours. The mini-split that I"m looking at pulls 1260 watts when the compressor is fully engaged (which isn't all of the time). The rest of our electrical usage will be fairly minimal...house lights, a...

    Hi Joey: We haven't done this enough to be able to do a true audit. The current house batteries (2 6V deep cycle lead acid batteries wired in series) are shot, so I'm having to replace them one way or the other. My end goal is to build a big enough system that I could run my ac unit as much...
