24v Great Idea. Higher voltage inverters tend to be more efficient and produce less heat. I think it would be cheaper and more efficient to have 1 300Ah bank if your batteries could be configured that way. This way you have one SCC and 1 battery you can still run all 300 watts of panels to...

Those should be fine. One tip i do though is I stock my freezer with about 3 gallons of water that turns to ice for thermal mass to keep the freezer cold when opened. I also have a switch set to turn the freezer off at night so as to save energy and use less battery power. My freezer only runs...

Cells have arrived! I will start testing tonight and hopefully have some ready to ship by weeks end.

Shutting off the AC draw us another option. After I test the new SSR I want to make a post on the various ways to use Chargery and interface with SCC and inverters.

I use LTO exclusively on my two systems and have no problems at all with the voltages. I use a midnite solar charge controller no issues with the voltage range. I also use a Samlex EVO inverter on one system and a Reliable energy inverter on the other system. The samlex can be programmed...

UPDATE. I have placed 180 Amp loads for 15-20 minutes on the 500A SSR the relay itself with the heatsink performs well. The Terminals do not! The screws heat up to about 180F after 15 minutes. The relay itself stays well under 100F The manufacturer is making me some new ones with larger...

I use breakers everywhere backed up by fuses. A 40 amp breaker gets a 50A fuse for example

I use 1/4 inch 6061 aluminum bought at a local metal yard cut it with a carbide tipped blade and my chop saw. Drill it with a standard metal drill bit. I have absolutely no corrosion or any other problems nuts and studs are as clean as the day i installed them a year ago well at least they...

actually I think eating them in parallel would be even better

Yes this is quite fine.and would probably give you highest output.

Yes there are losses but for the price difference you can add probably 1000 watts of panels or more. that will way surpass any loses.

I used to be totally worried about conversion losses do not get me wrong but living with the stuff in the real world for 3 years (all be it part time) I have come to realize they really are not that bad and can easily be overcome with more panels and more battery. Consider $300.00 for a...

With the heatsink but no heat paste. The mfg did tell me to add heat paste but I wanted to see if it made a difference. This also shows how I attached the cables.

How about this Craigism "To BMS so as not to be a mess!"

Actually it would be really interesting to see how things change over time. I think Im gonna put a log book in my solar closet and write these numbers down periodically. Great post!!

I had to drill 10 holes in 11 seperate buss bars. I used a Jig for everything but still found I had to enlarge a few holes. Next time I will just use a larger bit to begin with. There is really no need to be so tight.

Yes or the handle from a paint bucket. I once started my truck with an 18 volt drill battery and 2 metal paint bucket handles.

No these are Chinese relays I have ordered samples from 2 manufacturers. After i make proper tests and know more about what I am doing I have about 10 more manufacturers to check out. At what price range would you all find acceptable for a SSR vs a regular relay like chargery sells. I was...

Maybe we could get a DIY solar study group going. I will look tonight all those look interesting.

That's not a LTO bank this is. ??

The voltages are different because the BMS is shutting down after the CAPS have incrementally charged. It is not giving enough energy to charge the CAPS all at once. By switching on and off it is slowly charging caps until they are full then the unit works as it should. I say BMS but the...

You will never get full potential of your panels with one 100 Amp SCC you need either higher Volts or 2 SCC

Invisible!

Honestly I think they are all just wholesalers of the same battery

The funny thing is when I was in the 5th grade I tried to create the exact same thing. I couldn't figure out why it wouldn't work. Till I was told if I could get it to work I would be richest man in the world. I'm still not rich lol

I just hope he returns here before he sends MPP back. He never really seemed to listen to us. Seems like he came to his own conclusions and proceeded from there. Only hearing the replies that bolstered his theory.

He was on the forum last night. No responses. I had even private messages him with no response. I'm starting to think the whole thing was a "Rick Roll Or dare I say Randerson Roll

This is unfortunate that it is not 100% accurate but I guess if you want complete accuracy you need to pay much more for a batrium or other high end expensive device. I'm not sure if bad information is better or worse than having a Daly BMS with no information. maybe someday soon...

It seems that any time you discharge and then recharge the battery you are "creating a cycle" but discharging less allows you many more cycles.
