Well I gave lots of thought to the pros and cons of a DIY battery bank and decided to dive in. Went with the Seplos Mason kits purchased directly from Seplos. They went out the door last week and I should see them in about five weeks from across the pond. My system is a 24V system so I am...

I would like to add my $0.02 to this thread. Personally I have been on an ever expanding solar journey for the past six years and have a similar off-grid needs as the OP. Plenty of bad choices, expensive choices, along the way. I upgraded my system last year with a 24volt Victron Multi-Plus and...

You will need a DC to DC charger with the correct voltage range to connect two different battery systems. I would not try any direct connection without the appropriate middleman.

Battery Hookup is close to you. He has a cash and carry deal with a discount. Headed over there for cells in the next couple weeks myself.

Absolutely All large scale commercial buildings are done this way. Had some classes on it MANY years ago and I don't have the specifics in my head anymore, but I do know it allows for way more disipation.

It's how I'm doing my array being put in during the next couple months. Luckily I have some old 6awg laying around. Going to strip the insulation off it and bury it in the bottom of the trench, cover with 4" dirt, compact it in then run the conduit. I've got about a 100' run back to the bond...

Have been using the t-mobile home internet router since last fall. They had a deal if you switch service to them (2 phones) and got their home internet it was $30 a month and unlimited data cap. I haven't speed tested it but all I can say is it has been very quick for me. Reliability has been...

Batteries in series opens up potential balance issues. You also have four separate BMS instead of a single larger battery and a single BMS. Battleborn is over rated and as Mr. 420Ohms said is way overpriced. Many better options are available including building your own pack from raw cells.

Here's the screenshot

Okay When I figure it out I'll report back here what I learn so others have answers also :)

Check these links: Temco for solar cable and welding cable for low voltage hookups. Also crimp lugs and other goodies. The second link for the ULA ground mount system. https://temcoindustrial.com/ https://unirac.com/product/unirac-large-array/

Signature Solar has a 12v 100ah EG4 lifepo battery on sale for $239 with free shipping right now. I'm ordering one this afternoon

You just answered why the use of bare conductors are used extensively in commercial/industrial applications I don't know about solar array installation but I have other knowledge and experience in the electrical field and am trying to learn from you guy's. I have given some thought to this...

I strongly concur!

Been cutting a lot of wood clearing land. Bought a little used Echo CS400 15 years ago. I have literally beaten the snot out of that saw and it just keeps on ticking. Just a tune and clean now and then replace the primer bulb every two years and installed a carb kit about five years ago. Plus...

Maybe something like this: https://nomadicsupply.com/victron-energy-bluesolar-pwm-light-charge-controller-12-24v-10amp-scc010010000/ The controller will need to see a battery to operate so just rig up something to plug into the cigi lighter. Then use the load side to power the blanket. I see no...

I'm using the Uni-rack ULA system. Strong with easy assembly.

Yes that was it! I'm feeling back to normal now. Details are back. The SOC as calculated over the past year seems to be very accurate. Like a dumb azz I just didn't think of downloading the config before update and I'm on a new computer the old one has the original config file on it. This...

I know when we ground large commercial buildings most commonly many ground rods are driven at various points and all are connected with bare copper cable leading back to the main grounding bond. The purpose as I understand it is that a fault or lightning strike will dissipate voltage along it's...

It's not an idea. It's established grounding prctices.....

Using a bare grounding conductor (not inside conduit) from your array back to the bonding point is best practice from an electricians training standpoint. Ground rods at the array with metal pole mount can't hurt as it's already grounded.

That was my thinking. If you give it time, which I have plenty of, at some point (hopefully) things are good enough to commission it into the system Okay then float at 27.6v. That number sounds familiar because I think that is where it's already set at. Won't know till I return to Tenn. Thanks...

Okay I wondered the correct procedure on this. I have three packs being assembled soon and can only initially charge them one at a time so I figure get one to 100% and commission into system then work to get the next up to !00%. When the first one returns to !00% after being used then...

Just finished opening everything up and trying to do an inventory on all the little pieces. As best I can tell without opening up all the little bags of screws and whatnot all looks present and accounted for. The boxes all arrived in pristine condition very well packed. Shipping was lightning...

None of it is "easy" if your not experienced I also have a substantial investment in ground mount hardware for a smaller array of 3.2kw. It's not installed yet but I built another identical one for my son a few years ago. It all really adds up quick on initial outlay but the payback seems to...

Geez.... the three Seplos boxes are here. Was not expecting them for another month. I'm astounded how fast they got here. Also they have way more factory pre-assembly than what their assembly video shows and the printed out instructions show. The BMS is mounted to the faceplate along with the...

When the MPPT shuts down it has no power draw. The 27W you see is the consumption of the inverter and electronics of the Quattro. It is the same amount of consumption I see on my MultiPlus except when a heavier AC load goes on the consumption number increases with the load.

Your system and mine are similar in size and setup before you do any more expansion. I probably won't get much larger than it is now, small things maybe. I'm completely off grid and am 120v only, like you. No future plans for split phase although I almost went that route. The equipment is all...

If you have a long run you definitely want to consider 8 gauge. Others on here have links to calculators for voltage drop. You will have losses on a long run no matter what. Higher voltage strings are better (less loss) They have very competitive pricing. My run is about 125 ft. Strings are at...
