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.
