Yes it controls even the MPPTs. I have a fairly big setup: 4 x MP2 5000 with 4 MMPT and 2 Fronius Inverters to power my House. I would like to change from Tesla Model S packs to Lifepo4 for security reasons. So your Thread is quite interresting for me :D Jens

just have a look for "SimpBMS". It uses the original Tesla electronics on the packs and is able to balance the cells. It is also able to enable / disable different brand of chargers, precharge and shunt trip devices. Works quite nice for me for some years now. Jens

Works fine for me .... 8 Tesla Model S packs in a 2s4p configuration. -> you are free with paralleling packs up to 63 packs max. Jens

I don't know how it is in Australia. Here in Germany we have "phase compensating" meters. That means: if you feed in 1 kW on the first phase and use 500 watts on each of the other phases the meter reads zero (no payment). Knowing that you can simply start with one MP2 / Quattro, connect it to...

Amen ! Never the less i will change to LiFePo4 for security reasons. SimpBMS works quite well with victron equipment but you never know. I think if my 8 packs caches fire (for what reason ever), it will burn down my whole house. Jens

Hello to all of you .... i'm new to this forum and not a nativ speaker :D I use Tesla Model S packs for some yeas now. My total pack capacity is around 40 kW/h consisting of 8 x 6s Tesla packs. I power my whole household with theses packs and 6 solar arrays. The inverter chargers and MPPTs are...

You are welcome ..... Coming back to your thread: is the graph above from VRM ? Why do you think the voltages are going up after cutting off charge current ? I've never seen this before. REC-BMS seems to do a quite good job. I was looking for batrium but that would serve my needs too. I...

Victron uses DVCC to comunicate the charge and discharge currents to the chargers. Is DVCC enabled at your setup ? I use "SimpBMS" and a Cerbo. My Setup stops charging in any error condition -> i checked this more than one time. Jens Ah .... just saw in an older post that you use DVCC ...

Hi Bob, no ... i am using 48 Volt -> not kW inverters (3xVictron MP2 5000). My consumption is 15kVA max and that is about 300 Amps. My pack has 2x70qmm for negative and the same for the positive pole. This is quite adequate for the 300 Amps. The pack itself is able to handle 1000 Amps easily...

We pay 30 Euro cent / 36 US cent per kW/h in germany. So quite worth to use a battery :D Jens
