Total of 8 panels w/delivery lift gate at home. Preparing my dual enclosed cargo trailer/garage pv system. Mounting 4 on top of 7x14 enclosed trailer. May make a 2- 2 panel awning with the other 4 panels. Price was good for 3.2kw and they are supposed to have warranty.

Bought a couple from Walmart to experiment with $12.88 each plus tax

Which type is a better choice for a 48v battery pack with 3kw pv?

I bought a 12v 5 cft freezer and want to use it as refridgerator. I know if it was 120v I could plug a $30 temp controller into it. What to do with 12v?

I need to purchase a small amount of Iron Ridge racking. I searched the the archive but didn't find anything. I only need a couple hundred dollars worth but shipping is expensive. I even selected 7' rails and extensions. Thanks

I haven't been here for a while. I last posted about placing 400w panels on my 7' x 14' cargo trailer camper. I used them on my house instead because of the weight. I was able to buy Renogy panels for sale pricing so I loaded up. On the outside roof 9 - Flex 175W and the side of trailer 4 - Mono...

The more I think I know the more trouble I make for myself. My project is building out an enclosed cargo trailer with a 48v all solar boondocking system. I have been buying and stockpiling materials to use waiting for my trailer order to be filled. I bought 6- 400w Trina panels, Growatt 3000TL...

Planning a dual use 48v system. Will use it to power a camper and a shed when here at home. I need a battery that is portable as possible, Basicly in a case with wheels. I was looking at the 48vLI-ion Powerwall. Weighs in at 160 lbs but my camper has a cargo door so it will work. I would really...

I would like to charge from my truck as I travel.

From XUBA, anyone buy these? Rated for cold charging. Do they hold up as long as Lifepo4? More important are they safe for mobile use? Read where they are for cars. Do they make in 200ah or above?

I want to build 2- 24v 8s batteries and place in series for 48v 280ah. Batteries must be movable hence 2-24v any suggestions?

Was thinking on going with the 48v li-ion powerwall at bigbat. Will be using in a camper on the road and a shed at home. Not sure if there is a better choice since these are used. Connected to a 48w Growatt SPF LVM 120/240 solar inverter. . Thanks.

Ordered a BMS 4s 12v 120a to use in 4s 280ah battery build. Any problems? Recommendations?

I was looking on Alibaba and found this. I really don't like the wood box look or functionality. https://www.alibaba.com/product-detail/Free-Shipping-Factory-custom-one-stop_1600830355069.html?spm=a2700.details.0.0.3ff21907Ig6a6T Solar Storage Battery 280Ah Diy Kit boxes 10kw 15kwh 48V 230Ah...

I have my own ballast ground mounts, 3.2kw panels, hybrid inverter. Need permitting and all electrical connections for code compliant system. I will install the ballast ground rack and mount panels to them with clips.

Dumb question but can't find an answer because it's probably too easy. I'm finalizing my cargo trailer solar plan and have settled on a 48v 2S4P configuration. 2S will use a regular MC4 connection in series with a single 15a MCA fuse before routing inside the trailer. The 4P will connect with 4...

I bought a JBD BMS, it has only passive balancing and after reading over posts it seems an active balancer is a must for long term use and care. I was thinking of this HelTec 1.2a in a 16s Please comment or suggest alternatives. https://www.aliexpress.us/item/2255800603941164.html

Price is $850. plus shipping $302.60 to the US. $1,152.60 sounds very good. https://www.alibaba.com/product-detail/Rechargeable-LiFePO4-battery-48v-100ah-5KW_62126801354.html?spm=a2700.galleryofferlist.0.0.a8ed19a5Nr9Xio
