Finally made the decision to upgrade to lithium for our off grid cabin. The AGM's we have are now 3 years old. Still working great, but we decided to increase our capacity and switch to heated lithium (Off Grid cabin in Wisconsin. Get's below freezing during hunting season and when we want to...

Just got done designing and building my own indoor compost toilet for the cabin. Cost about $140 which includes: *4x8 sheet of 3/4" sanded pine plywood *Quart of Gun Stock Stain *Quart of Semi-Gloss Urethane *Hinges *8-Gallon Garbage Can *(4) 4-Gallon Garbage Cans *Urine Diverter (Bought from...

I know how to wire these up to make them a 48v volt bank. (4) CHINS Lithium 12v 100ah batteries (Photo Attached) Just looking for photos of anyone/everyone else's similar style bank. I can stack them on their side or just leave them as is. I plan on using 2/0 cables. Anyone want to post a...

Now that I've tuned in my off-grid cabin system, I'm finally getting around to starting up a system for my house. This will be off grid and I'm starting it primarily as a back-up for power outages and a supplemental system. If it matters, I'm looking at starting with 800w of panels, 2000w Pure...

Slowly but surely looking to refine my system now that it's up and running. Check the "About My System" link in my signature if you need more details. Looking to add and BMS to my set-up. I currently have 205ah of AGM batteries. (1-100ah, and 3-35ah batteries) What BMS should I get and how do I...

A very good friend of mine who used to be my chef when I was in the restaurant business is looking to custom build his own 14 foot trailer and hit the road with a food trailer. Almost all of the equipment will be gas, but he'll need to power lights, a fridge, freezer, microwave and possibly a...

Looking for a closed circuit security / surveillance system to help protect our off grid cabin. Our old cabin had been broken into in years past, and now that we've built the new one we are hoping to maybe get a system in place to keep an eye on it. We are 100% off grid, so our solar setup...

We just built our cabin from the ground up. Concrete slab, 24' x 32' cabin. The cabin is wired for standard 120v AC current. Solar Panels: (3) Renogy 100w/12v panels wired in parallel. (Partially wooded area, so we want panels to be separate) Charge Controller: Renogy Rover Elite 20a MPPT...

I continue to build my system and make adjustments as I go. Looking for advice on setting up my battery bank to fit best with the rest of my system. Current Set-Up: *300 watts of panels (3 - 100 Watt Renogy Panels in parallel) 21.6 VOC *Renogy Rover Elite 20A MPPT Charge Controller *Battery...

I just installed my 3rd panel this weekend. Before I left today, the sun was hitting the panels fully and the controller was telling me the panels were only sending 22 volts / 8 amps to the battery bank. Tell me where to start troubleshooting. Here is the set-up: (3) 100 watt Renogy Mono...

I have been slowly building my system. Started with 1 panel and a long cable with an MC4 connector attached. Then added a second panel, and thus had to buy a pair of MMF/FFM to connect them parallel. NOW...About to add a 3rd panel. Question is, I will most likely end up adding 1 more panel in...

Building my battery bank slowly due to budget constraints. Eventually I will purchase either lithium or some bigger AGM's. For now, my initial set of batteries were Marine deep cycle batteries (SLA's) I just added 3 AGM's to the battery bank. Question is, how should I set my Renogy Rover Elite...

I trusted some buddies to install another panel for me and this happened. Should I leave it connected until the replacement arrives? Will this still draw a little energy or is it a detriment?

I may have already solved the issue, but just looking for ongoing input on my system that I'm building. Initial Set-up: (1) Renogy 100w Mono Panel Renogy Rover Elite 20a MPPT C.C. 1000w Inverter (2) Marine Deep Cycle batteries (Estimated they are 50ah batteries each) I was having no problem...

I am finally ready to pull the trigger on adding to our battery bank. Problem is (My Fault!) is that I need to get a battery in hand before the weekend, and it seems every supplier needs 3-5 days to ship. I am in Wisconsin... Anyone know of any brick and mortar stores or places that sell...

I previously posted my wiring diagram, but I have since added a 12v DC Water Pump and have also added fuses and grounding to this diagram. Right now, we only have (1) 100w Renogy Panel, and a small battery bank. However, I'd like to set this up for eventually having (2) 100w panels and a...

I am designing my water system, and just want to figure out the best option for wiring the water pump. Looking at hooking a tankless water heater and 12v water pump up to feed the cabin with water from a rain collection barrel. What is the best way to hook up the water pump? It is a 12v DC...

I would love to see everyone post their shower set-ups. Looking at purchasing an LP tankless water heater/shower set-up. We have a rain collection barrel for water, so we'd also need to hook up a water pump. Looks like most water pumps for these systems are powered by DC, but I've wired my...

Our cabin is almost completed. I do have my solar panel hooked up and it's charging my SLA battery bank. We haven't finished the interior of the cabin, so I've been able to get away with charging the battery bank without a final vent system. Right now it can vent through the roof vents, but...

I'm really trying to evaluate how to build the battery bank for my system. Assuming the budget is the same (It appears you pretty much pay $1.80 per Ah)... Is it better to: 1) Buy (1) 100Ah AGM battery ...or... 2) Buy (3) 33Ah AGM batteries My investment will pretty be the same (Exception that...

My brother-in-law is in the telecommunications business, and may be able to get batteries from this company at wholesale prices. Anyone have experience and/or opinions with the NPP brand of deep cycle batteries? Thinking of pulling the trigger on the #NPD12-100Ah Always love trying to get a...

We currently have 2 Deep Cycle Marine batteries. (Sealed Acid). Approx. 50ah each. We will be expanding our battery bank soon. Question is, if we are going to expand our battery bank, Is adding a 100ah Sealed going to work? I've seen somewhere that your battery bank is only as good as your...

Forgive me if you are on all of the different Facebook DIY Solar sites etc and saw my request for this already... I've done a good job at our new cabin of selecting all low wattage LED lights etc... The 1 guilty pleasure we would really like to pull off is a coffee maker. We already have a...

I'll be finally installing my system at our new cabin this weekend. There is a good chance that the 40 ft. 10 AWG cables I bought to connect the panels to the controller may be too short. My question is will there be a lot of current lost if I need to get an additional cable to make up the...

Looking for the little LED display voltage meter to tell me the status of my battery bank. I know I can order them online, but wondering if this is something I can find at my local Home Depot or Auto store. Picking up my first panel today and I want to set the entire system up at home and test...
