I see from your picture that you did provide heavier cables for the battery to rest of system, so you did recognize the need for higher current capacity there. I suspect you are not measuring equivalent current on negative and positive sides. How are you measuring current? You would need to...

Remember that the cables going to the inverter needs to carry twice as much current as the cables between the batteries. If your intent is to add more batteries in the future do not continue to connect in this manner. Instead use a star configuration with all positive battery terminals connected...

You won’t be able to hook it up with your van battery. Different chemistries mean different charging profiles and different charge levels. The stock alternator won’t be up to charging the LiFePo4 either. Consider a second beefier alternator designed for charging this type of battery. As for the...

Here's the link to the video you are referring to. Note Will mentions this might be an issue if you have three or more batteries in parallel, which it sounds like you are not. His main concern seems to be about one of the batteries going bad which can affect the other batteries. He mentions that...

Which video?

To clarify and correct something I said that might be misleading. If you compare like kWh capacities then serial and parallel can charge at the same speed. Two serial batteries at 12v 200 Ah, are the equivalent of two parallel batteries at 24v 100Ah. Both have a .2C rate of 40A. The parallel...

Here is my thinking on that question. Two batteries in series can get out of balance with each other, just as the series cells within each battery would get out of balance if not for a BMS. If one of the batteries should die for some reason, you no longer have 24volts. With two batteries there...

Not sure how deep those studs go in. Maybe drill and tap them?

Just received two of the Lynac 25.6 (nominal 24) volt 100 Ah batteries. Note that these are actually rated 120 Ah but Lynac recommends only 80% discharge so market them at the lower capacity. Price was $1482 Cdn each, after 10% discount. Even though each of these weigh 50 lbs each there was no...

Buy them some nice jewelry first. ?

A quick , LATE, question. Why not configure these as 2P8S? Then you would only require 1 BMS, albeit one capable of a bit more oomph in the balancing.

Typically made from tempered glass. If you are comfortable parking your car under the trees then your panels should be fine.

As long as you don't run them on the same circuits. So, you need to isolate your wiring so each has their own hot, neutral and ground. Outlets would then be connected to one or the other.

Drill, tap and short bolts?

MidNite has one for the panels. It connects in at the combiner box. Basically, it will route surges on the positive or negative solar line to ground.

I think the likelihood of a lightning strike is lowered since there is no direct connection between the vehicle and ground. And I'm still wondering whether making a connection increases the chance of a strike.

I checked the manual on the Multiplus and I see that it has a ground relay, such that when to connected to an external AC source the neutral is connected to chassis ground, and when connected to external power this is disconnected, thus I believe, achieving correct bonding. Mine is a custom...

A lot of generators are not to be started while plugged in to any load, and in looking at the manual for your generator this seems to be the case. So if you want an automated start it would need to accommodate this limitation. So the automation would need to detect the low situation, start the...

Point made but I’m only planning on 30 amps max. To do as you suggest would require isolated circuits.

Good point. You just saved me some money. Now feeling mind numbingly stupid.

I have the LV2424 all in one unit. This has an automatic transfer switch built in and configuration that let's me control when the unit pulls from utility or the built-in inverter. I'm going to have a shore power connection and a generator, which I will connect to the utility side of the...

Okay, taking this topic a little sideways. I have the same issue, as my LiFePo4 system is 24 volt. I have a 12 volt buck converter for anything that requires 12 volts. I was considering adding a big enough diode to support the required breakaway amperage, but also stop the truck alternator from...

If you put Will's ID, like this, @Will Prowse then he is notified of the message.

I reviewed my requirements and the 400 amps was grossly overstated. Still waiting on getting the BMS delivered.

Actually, I have to correct my earlier statements. I did a lot of research on this since I actually saw very few people using blocking diodes. If you are using a devent SCC you won’t need to worry about needing a blocking diode. The only case I saw where they were required was if you were also...

Well, it looks like I will need some headways to help balance some cells. The problem is that BCH and BHU are both sold out, and there seems to be a lot of other vendors selling repackaged crap as headway. Anyone know where I could pick up a half dozen or so?

The odd thing I noticed is they only will insert when I orient them in what looks like a backwards orientation.

No, burn yourself with something hot enough it leaves a sear mark, very little swelling. Still smarts though. Used to do it all the time taking the racks of baked potatoes out at a restaurant I worked at.

I was wiring up my BYDs for my new BMS when I accidentally let go of one of the lines I had attached to one of the cells as I was attaching it to a terminal block. It swung down and welded itself to the main positive terminal. Suddenly smoke was pouring from the battery. I quick grabbed the wire...

For the shore power breakers, consider an additional breaker just for the air conditioner if you are only going to run your A/C on shore power. it would only be live when shore power is available. Just don’t join that to the AC output of the all-in-one. Put some kind of mark on the outlets that...

I’ve the 2424. Most people don’t keep these out in the open, usually in a small alcove. It’s about the same sound as my server Which admittedly has cheap fans. If I find it bothers me I’ll put a better fan in.

Inverters don’t charge, they discharge. What did you mean to say?

If I need a bigger inverter I’ll just add one on separate 120 circuits.

I’ve got the MPP 2.4 kWh model. My thoughts and observations: Positives you’ll require less space for the AIO (All-In-One); wiring is less complex; programming is mostly in one place; easier monitoring through a single interface. Negatives If it breaks you lose a number of your power elements...
