MPP all in one with Tesla cell?

I’m really hoping to match the mpp all in one with a Tesla cell and was wondering if they’re even compatible and if it is, if I should/could connect a battery balancing system. SOS

As a Tesla user you had better do your homework and look up the specs before you spend the $600. Most 24 volt inverter/charger units are not compatible with a 6s Tesla 5.3Kw 233ah module. Most 24 volt inverters shut off above 20 vdc. Only the Victron Multiplus will operate down to 19vdc. Not to mention these MPP units dont have similar programmable AUX IOs and Remote shut off to work with a two lead BMS control. The Multiplus works down to 19vdc, has a temp sense, 2 Aux IO ports, remote switch and addition relays that you can program to start a generator for low voltage. Also has the added benefit of being a hybrid inverter to use in conjuction with a generator if your generator needs additional load.
The Tesla has a voltage range of 18 volts to 25.2 volts. I only use between 19 volts and 24.4 volts. Then multiplus 24/3000 cost $1500.
I would make a guess the 24 volt MPP is not the unit for you unless you are willing to give up half the range of your Tesla and be limited on BMS automation.

Are the used Tesla battery packs on Ebay sold with a higher capacity utilization rate than that BYD module Will has looked at recently? Not sure if that term is correct, but didn't Will say that his BYD pack was down to ~65% ? I was wondering if the Tesla used packs are rated any higher? thus last longer?

Doesn't the 24V MPP all-in-one system that @Will Prowse has talked about in his videos have configurable voltages that would make it compatible with a 6S Tesla module? If so, it would be awesome if Will could revisit his Tesla module in a video!

i just cant seem to find proper engineering specs and limits for MPP inverter/chargers similar to the data Victron publishes.

Probably not as detailed as the Victron datasheets but they do exist, here for example.

It only show nominal 24 vdc and max at 32vdc. It does not state low operation voltage. The Tesla operates at 18vdc to 25.2 vdc so i am going to make a guess that this 24 MPP is not capable to use with a Tesla 6s module. Attached is the Victron Multiplus 24/3000 specs witch states an operational range of 19 to 33 vdc. It also states all the AUX relays of 3. Maybe Will can post his operating manual for the 24 /120 MPP unit.

I guess you might be better off searching for a 12V (nominal) battery system unit for use with these Tesla modules, rather than a 24V. Looks like you get up to around 3,000W output running with a 12V nominal input. At the 3,000W rating, you'd be pulling 250A, which I presume these Tesla modules would be able to handle.

This Sigineer inverter charger is designed to work with Tesla model s batteries. It's not cheap but it's a 6KW model and supports 3x surge so it's actually not too bad.

You cant use the Tesla Module with a 12 volt inverter system. It is a 6s module.

Similar in price to the Victron Multiplus 24/3000. The Victron is a hybrid inverter/charger that has a second AC2 out and can be programmed with a computer. This inverter would be fine for larger RVs or home systems. 90#s of wt. Is a big issue.

I can't find the user manual for that one, here's the user manual for the PIP-HSP/MSP: http://www.mppsolar.com/manual/PIP-HSP,MSP 24V/PIP-HSP_MSP 24V manual.pdf

Starting on page 17, it gives these voltage ranges:

Bulk charging (CV): 24.0-29.2V
Float charging: 24.0-29.2V
Low voltage cutoff: 20.0-24V

So, it looks to me like that model, at least, is compatible, but it won't allow you to fully discharge the battery. 20V low voltage cutoff might be a good choice for maximizing battery life, though.

Yes, I see what you mean. A 12V (nominal) inverter will have a DC input range of around 9 - 17V, which would be exceeded by the Tesla module.
