    Think your car is cool?

    I have a jaguar xkr and my wife has a jaguar e-pace, so I'm vaguely familiar with what jaguar is doing. I'm also not crazy about it. I don't think ICE is going anywhere any time soon, but at the same time, I wanted an EV just to try it out and have fun. But I wanted one that didn't suck, like...

    Think your car is cool?

    I don't plan to ever use a fast charger, I plan to just leave it on a level 1 all the time. I work from home and sleep from home, so really the only time I drive is after hours. Over the past 4 months I've averaged 25 miles a day for driving, and 35 days i didn't drive at all. The largest...

    Think your car is cool?

    I'll get some closer pictures. The specs are not released on how much total capacity it is, or what the wattage it is currently generating at. Hopefully in future software updates, that information is coming.

    Think your car is cool?

    I'm told that on a sunny day, it can add 8-10 miles of range. For the lifetime of my vehicle, approximately 2 weeks, I've added 76 miles of range. I'll be watching this and see how fast it goes up. Right now it's parked in the sun and generating 63%. Sure, it might be a gimmick. But it's a...

    House burned down

    OP, sorry to hear. I'm really glad you shared, though. I'm building out a system as we speak (non-victron), and was afraid I'd become complacent in the possibility of something like this happening. I hope that it wasn't as devastating to your family as it would be to mine.

    Think your car is cool?

    If they made the retractable toneu cover a solar panel, that would have been a pretty sweet move. But instead you can stand on it. So I guess that's cool, too?

    Think your car is cool?

    James May reviewed the fisker karma back in 2011 on top gear and gave it a favorable review. Then they compared it to the eagle eye thrust. It's when I first heard of fisker, and have been following ever since.

    Think your car is cool?

    I know it's not diy, but I like it and I don't know why more companies don't do it. So far 24kwh generated and 76 miles.

    What was your most interesting recent non solar project?

    I used these to replace ignition keys on two tractors so I have remote start. It's handy when it's 3f outside, I can prime the glow plugs, then start the tractor, then turn the ignition on, and it'll warm up before I go out and blow snow.

    What was your most interesting recent non solar project?

    Fence bought and installed. Chicken manure spread, plant food spread. Tiller had a horrible accident, it picked up a rock and locked up. That was fun. Installed a new spigot. Tapped the washer's cold water supply. Used sharkbite for the first time. I was skeptical as hell, but no sweating...

    Is it common for rodents to chew PV cables on ground-based solar panels?

    No, the fresh air intake in cars i have in moth balls is in the wheel well.

    bms heat generation

    I'm building a closet into a wall that will contain 6 packs totaling 90kwh. Each bms is 100a per 15k pack. I'll be sliding each pack onto a shelf and closing the door. My concern is do I leave the bms on the inside of the shelf, or outside of the shelf? Each shelf will have it's own door. Think...

    bms heat generation

    I have my batteries in a sealed and insulated cabinet. Does the bms generate any measurable amount of heat? It's in the basement on a concrete slab. Should I put it outside the box or is it ok inside? The box is almost the exact dimensions of the cells. It's a sp17s005 16s bms from BHU.

    Build or Buy For a Beginner

    A solar generator isn't a thing. I wish the industry would stop calling it that. There are 3 different things that are very similar. wh, or watt hours, it's capacity, how much juice is in the cup watts, these are two different numbers. one is dealing with how much power is generated by a...

    What was your most interesting recent non solar project?

    Finished clearing the area. Got my tiller ready last month and broke it out. Started right up, and hit that red clay hard. I'm going to need some fertilizer. Maybe something nitrogen based.

    Do you own an EV and charge with solar?

    My garage is not tied into my solar system for the time being, it'll just be a subpanel that will power a handful of circuits. I'm not going to build the big system out just yet, but I can throw together a small system on the pavilion next to the garage easily. The bigger system will be ground...

    Do you own an EV and charge with solar?

    One of my biggest motivations of building out a solar system is getting truely off grid, and that means everything, vehicles included. Which means I need sufficient production to also charge a vehicle. My current system I'm building is 4.2kw with a 3k inverter and 15kwh battery, but once...

    Thar she goes! Not started in 9 years, once the 1951 ferguson to30 was running she couldn't be stopped. Even with 2 flat tires.

    Low vs High frequency inverters

    Post first, buy later. And those 24v 100ah batteries are typically not very well built or long lasting, where the eg4's have good reputation, warranty, and support. If you don't know anything, i'd start watching youtube, will's channel is strait and to the point, no gimmick or bs. You don't...

    Shaved the cat today... My wife has this cat, lucy, a long hair rag doll who she overfeeds. Lucy is a bit on the pudgy side now, and had matting on her sides, back, stomach and neck. She would brush her but brushing a cat against their will is not recommended. So she made an appointment...

    What was your most interesting recent non solar project?

    Backhoe in the way, so it needed to move. It's a 1953 oliver 77 industrial. Haven't needed to move it since I dug the footers for my shop. New fuel filter, new fuel, new battery, half a can of starting fluid, tires inflated. It sank pretty well over the years so I had to rock it back and forth...

    Should i top balance now or wait?

    I was hoping there was some discharge tool that could be set to measure watts and automatically shut off at some point. I'm surprised there isn't already.

    Should i top balance now or wait?

    3 responses and 3 different answers. Sweet. They're 280ah batteries and i have no idea what SOC they are. I was thinking of taking them to 3.45 or 3.55 and then battery assembly. Something I can do after hours, where daylight is more building and going to home depot. And yes, i'll be doing all...

    Should i top balance now or wait?

    Should I top balance my 16s battery now or wait until it's time to put into production in about 2-3 weeks? I still have to finish the power room, racking, inverter wiring. Which wouldn't take much but I have other projects going on and working and wife and kids and the whole lot. My cells are...

    ring terminals

    My bms wire is 24awg and i need m6 ring terminals. The only thing I can find is m6 to 16-22awg. Will that be small enough to get a good crimp?

    Recomentations for a 1000watt or less inverter charger

    Why do you want 1000w or less? You could get a 3k and just use it less.
