Not sure if I will do grid tie straight away but will want to later for Internet metering. So am studying choices.
The set up: I'm assembling an off-grid technique using a Deye HV hybrid inverter 30 kVA 220/380 V employing a personalized pack I created employing 8 Tesla design S battery modules in series with Orion BMS two. The setup is straightforward, I have a a hundred and twenty-240V to 24V DC converter, wherever the enter is the HV battery pack plus the output powers up the 'Often On' and 'Demand' electricity inputs of the BMS plus the good terminal to the GIGAVAC contactor coil, the unfavorable terminal is controlled via the BMS's Multi Goal Help output pin.
I can run it in UPS method With all the circuit board cutover change established to backup situation and it will work much like the diagram previously mentioned.
If u such as this undertaking and wish to assist my perform to add more protocols u can invest ur time in addition to if u can spare some $ might be terrific much too!
Key detail I am continue to worried about would be the 'Cost', 'Discharge' and 'Balancing' requests that the inverter seem to foundation its logic all around. I'm ignoring them for now, since the operation for cost and discharge on the Orion BMS 2 operate in a different way, but I'm trying to emulate the 'response from battery' concept on People requests.
San Diego Apr 26, 2025 #25 Pursuing up: the SOC overestimation issue inside the inverter is unrelated to the amount of battery enter terminals employed. Foolish assumed looking back, however it gave me a thing to test when I'm on the lookout for far more Thoughts and knowledge.
The only difficult bit is the value: Though the Ioniq 9 is Amongst the most attainable electric 3-rows, these vehicles remain byd atto 3 ราคา costlier than their inner-combustion competition. Hyundai and Kia items are likely to possess fantastic lease deals, even though, so keep an eye out for anyone.
In battery backup manner the inverter can offer electricity approximately its output Restrict or even the output Restrict with the connected battery, whichever will be the reduced.
The Deye inverters are “self-adopting” to battery devices, as a result there isn't any environment from the inverter in addition to
BMW's useful content largest and most deluxe SUV has generally been simple to advocate, owing to its combination of a long selection and supreme consolation. And now, due to a wide array of updates, it claims to generally be even better.
I was originally thinking about EG4 but I do not believe they tackle 400v storage batteries still, appropriate? Identical for Victron, accurate?
I was wanting to hate the Hyundai Ioniq five N’s foolish bogus dual-clutch shifting. Then I tried it at Laguna Seca, and I had been hooked. The 5 N’s very convincing imitation of a transmission was not simply enjoyable, it had been helpful, supplying me audio cues to help you me gauge my own pace on track.
JK dont have an embedded RS485, u will use an adaptor, the signal is acquire it from TTL port Using the adaptor. so all jk assist rs485
Do you think It might be possible to emulate a fictional SOC of 60%? to make sure that it does not Restrict upload find more or down load?
