    $54k Sunrun OR $0.31/w New Panels Pallet + Growatt Grid-tie = Good Idea & ROI??

    I had a consultation with Sunrun the other day and they quoted $54k for a 11.2kw grid-tie system. That is just insane, and I figured it would be, but still wanted to see what they were offering. The ROI on that is a TOUGH sell. We are fortunate enough to get 1:1 net metering from our utility...

    Golf Cart Battery Bank?

    I have a golf cart with a pretty large battery compartment. It currently has 6x 8v lead acid. An idea I am pondering is replacing the exiting batteries with a DIY 320AH 48v Lifepo4 battery pack, and making it accessible as the battery source for a home backup inverter (similar to the F150...

    Sungoldpower 48v 4KW Inverter/Charger troubleshooting

    I'm having issues with my system not charging up the batteries all the way. I suspect it has something to do with the inverter/charger, however their support I believe is in china and I have had very delayed communication with them so I wanted to run it by you guys to see if you have ideas...

    Up and running 48v 10kwh RV

    Finally have my inverter and battery pack wired and running! Runs both air conditioners (15k & 13.5k btu) with ease at 60% load. I get a quick beep when the second one kicks on from the compressor surge, but I expected that and chose a low frequency inverter so it could handle it. 2x Gyll 48v...

    Ground Neutral Bonding: What is this and when do I need it?

    I am in the process of wiring up my inverter and batteries. I have heard a lot about ground-neutral bonding and hazards associated with doing it incorrectly. I am having difficulty finding when and why to bond the ground to the neutral. I couldn't find it addressed in my manual, and I assume...

    VHB Purpose, Price, and Alternatives?

    I am considering using VHB tape for an upcoming project, but am finding that it is quite expensive! For 2" wide it is about $5/ft and I'm going to use potentially 80'. (adhering unistrut to the fiberglass roof of my rv for solar panel mounting) I'm not trying to spend that much on tape, so that...

    Las Vegas Santan Solar Group Order

    I am looking to purchase 8-10 panels from santan solar, however shipping comes out to about $25/panel. I can order up to about 20 with the same shipping fee, which would bring shipping down to about $10/panel. Anybody interested in doing a group purchase, shipped to Las Vegas and save on shipping?

    Panel placement on roof of Class A & VHB Tape Mounting

    Any recommendations of doing it differently, or does this appear to be an ideal layout given the factors involved? Layout considerations: 1. Grouping panels that are next to roof protrusion (AC unit or vent) in series, since when the sun is not in their favor they will likely not perform. 2...

    48v System, considering switching to All-in-One before installing

    Before I install my off-grid RV 48v system, I am considering switching from a Sungoldpower (aims) 4kw 48v pure sine inverter to a MPP solar LVX6048 48v all-in-one reviewed in Will's recent video .

    48v System Wiring Check - Help Please!

    I've put this project on the back burner for a while because I was a bit overwhelmed, but I'm trying to finally tackle it... So I did my best to make a "wiring diagram" on paint with my components. This is just to draw out the idea and work out the kinks. Would those experienced and...

    Inverter/Charger Bypass Insufficient

    I purchased a 4kw 48v low frequency pure sine inverter/charger/transfer for my upcoming build. Considering the cost of the Victron unit that had many great features ($2700), I decided to try a less expensive route ($900) with a couple compromises to see if it will work for my purposes. My RV...

    Charger Help 48v 100a Charger?

    I'm still in the process of planning my system and knowing what to expect and I realize that I misunderstood the charger specs on the inverter/chargers that I have been considering. When I saw a 40a charge rate, I assumed it would be 40a load from the 120v supply, (4800w). Now I realize that...

    24v 4kw Inverter/Charger AIMS & Multiple Replica Options?

    I am doing my final research before choosing the inverter/charger for my system. I am mostly decided on the 24v 4kw AIMS low frequency because it can handle 1200w surge for 20s before shutting down (allows me to start and run the air conditioner). The AIMS unit is rather expensive at about...

    13.4kwh RV Build Planning Advice

    I placed an order in the group buy for 16x 280ah cells. So far this is my only purchase, but they are going to take a month or two to arrive and I'm trying to have everything else in order or installed so they will be the last step once they arrive. Once I have the hardware components...

    Hey guys, I am in the planning stage of my RV solar and lithium build. I just purchased the RV about a month ago and I really want to be able to camp without hookups and not need to run my generator. I am trying to stay within a $5k budget and would like 5kwh+. From what I've been finding...
