He'll still need something to generate the power, either solar or something turning a rotor inside a stator.

You have 2 options. Do as @Jim Burrow said and connect a battery charger to your gen and use that to charge the batteries, this however is inefficient and you're going from DC -> AC -> DC and there's losses every time you switch over. What you really need is a DC generator, alternator or turbine...

That's my system. it's a build thread so that's why it is chronological. What do you want to know?

That's quite a bit of voltage to each cell bank. 57.6/12 = 4.8v which is much higher than Li likes to go, just something to keep in mind.

It's not secured in any way. It's just a CAN protocol, here are the details of the packet bytes https://www.elithion.com/lithiumate/php/controller_can_specs.php Or just buy a BMS with the interface already built in like the ones below: SimpBMS...

Umm.. Did you not loot at the datasheet? There's 3 models, the highest is 6kW. For DIY batteries you'll need a BMS with CAN output which is how the inverter gets stats on the battery. Both SimpBMS and EVTV Controller have support for CAN, or you can write your own if you use TomDebree or...

SMA has an inverter capable of using the whole pack without rewiring it. DC voltage range/ DC rated voltage 100 V - 550 V / 360 V https://files.sma.de/dl/30859/SBSXX-US-DS-en-20.pdf

I have a controller that communicates with the OEM BMB boards in the modules to get cell voltage/temp readings, the controller has contactors to disconnect the pack in case of over/under voltage, it also tells the BMB boards to balance using the built in resistor bleeders. Finally I also have a...

I have the 12kW version of these and they work pretty well. https://www.sigineer.com/product-category/inverter-chargers/tesla-battery-inverter/

That range will over discharge a Tesla module as it's only supposed to go down to 18v (18/6=3v per cell) and it'll also leave some capacity unused since the max on the module is 25.2 (25.2/6=4.2v per cell). The top end isn't as big of a deal, the over discharge however will destroy the module...

Yes, Opinions are totally fine. However, in a forum where the main goal is to have discussions on how different mechanisms work, opinions passed as fact can be dangerous. I wasn't trying to be an ass, I was simply pointing out that not all meters will detect backfed power as consumption.

Yea... that's not how meters work. The meter doesn't "record in reverse" when the voltage rises above the grid supply voltage. You're charged for the kW which is the voltage*amps used. Voltage is just the speed, amps is the volume. I think you're getting hung up on the fact that AC alternates...

What are you talking about? Meters measure power in kWh which does flow forward (increases your consumption) or backwards (decreases your consumption). When you say "the solar panels just have a higher voltage" are you referring to the 350-600VDC they produce?

That's only on some cases. Some new meters detect power flow direction, if you're not signed up for net metering you just won't get paid for your export, it won't charge you for your export as if it was usage. as always YMMV depending on your meter.

What's your budget? If you're due for a new inverter there's a few that support Tesla modules out of the box (sigineer) there's also others that can be configured for your own high/low points (magnum for example). Or like someone mentioned just add another module in parallel which will...

Do you have the mate3 controller? I belive you can program one of the relays to be turned off while gen power is enabled. To said relay connect the coil of a large contactor, use the contactor to break the output line of your GT connection to your panel. This will prevent your GT system from...

I built a dashboard and control panel for my system using Node-Red, InfluxDB and Grafana. it all runs on a RPi

You cannot AC couple a GT system to a generator. By design GT inverters will output 100% of the sun they receive (with some caveats more on this below). This means that if your micros sync to the generator (I say if because they require a clean sinewave that only inverter generators can produce)...

Here's the build for my system where I used a whole battery pack. https://secondlifestorage.com/showthread.php?tid=7743

DO NOT DO THAT. I recognize that remote, it's made by Sigineer, they're the OEM and everyone else just rebrands their stuff. The sigineer manual for that remote has warnings not to cut it while plugged in because it carries 12v and it'll damage the inverter. Point is Ethernet is not 12v and...

I think the main question here is, what are you wanting to power and what power does it require? stepping voltage has inherit losses so unless you have a specific reason for it it's better to skip it. For example, if your RV already has an inverter which converts 12VDC power from batteries to...

Why 12/24v? Do you have appliances that use DC or is that what your current RV inverter takes? Water cooling will depend on our load and charging rates. M Tesla battery pack doesn't require any and I charge/discharge it at 12-15kW

Here's the thing, you're getting into low level electronics which is even more involved, sometimes ADCs need extra components in the circuit when measuring certain levels. Its even more involved when you don't have a library to use out of the box. Now I'm not saying it is not possible it's just...

I use a Sigineer 12kW inverter/charger AC coupled to 12kW of solar with my 60kW Tesla battery pack and it's worked great, it delivers exactly as advertised and the peak of 36kW is insane, I didn't even need a soft starter on the AC (although I did install one). One caveat, I wish there was a way...

That's what happens when "Corporations are people" they buy politicians to create legislation to line their pockets.

Agreed, We actually lower their bottom line by producing power for them. The problem is their investment on large power plants is already made and now they don't get the revenue they used to get off our monthly bill so they're trying to get money a different way. It should at least be equal...

If you have solar and are grid tied (essentially using the grid as your battery) then you should pay the fees, after all you're using the infrastructure. If you're off the grid and store your own power, then no, you shouldn't have to pay fees for infrastructure you don't use. There, was that...

Here's a sample flow I use with a PZEM-016. https://pastebin.com/Jhhq4K6F and here's the registers from the manual of the PZEM-016 so you can cross reference what goes where on the flow to the manual. If you have the registers for your midnight I may be able to cook something up.

I actually have some stuff also running on MODBUS so if you want some code examples I can send you a couple things.

Take a look at the Node-Red dashboard pallet, you can feed it your data directly and even make functional controls from it. Here's mine Of course if you want more than a day or two of data to review I'd suggest influx DB and Grafana Here's my Grafana historical graphs fed off influx DB

Wire gauge is mostly related to amperage. Simplest rule is take the max amps your system is capable of delivering and use that to figure out gauge, in your case you can use watts law to get that. I = 400W/12V = 33.3A (Note that I used the rated watts your inverter can deliver, you could also...

Using a Pi to capture serial (RS232) is pretty simple when you use Node-Red. Here's a few links explaining a couple examples. But the basic steps are. Connect the serial from your inverter to the serial (or usb when using a converter) of the PI Install Node-red on the Pi Drag over the serial...

The main question here is. Does that inverter bond neutral to ground? Some inverters do this in order to get around the issue of a floating earth connection which would cause some appliances from working. In the US at the main panel your neutral bonds to your earth. If a fault were to occur...

What you're looking to do won't work for a couple reasons. The battery pack has 2 contactors built into it, meaning that unless the car sends a CAN message to the battery module the contactors won't close and you won't have any HV power on the cars wiring. You could root the MCU and send your...
