Very happy with the system so far, but still need to do some tuning with regards to getting the Lynx shunt and the JK-BMS’s to communicate correctly and also the Dynamic ESS settings.
I am still going to add the EV charging station NS
And make sure it has a separate ventilation system
Looks quite nice. You are aware of air flow of the MP2 and also charger ? Hot air leaves the systems on the top back side of the devices … victron states to leave some space for that reason.
Als er veel vermogen uit de batterij of van panelen naar het net gaat wordt het bij mij knap warm in de kast met maar 1 rs6000, ik heb een afzuigventilatie in de kast gemaakt, gekoppeld met de ventilator in de RS.
Bij jou lijkt alles achter een glazen deur te zijn opgesteld? Ook de Cerbo wordt aardig warm bij mij..
Thank you!
I have limited space so I tried to make a bit of compromise. It does indeed get quite warm so need to figure out how im going to do the ventilation . I’m looking at adding some additional fans to get rid of the heat a bit better.
Ja er komt idd nog iets van een ventilatie, wil nog een beetje berekenen hoeveel m3/h ik daarvoor wil doen.
Het is een aparte ruimte tussen de garage en gang waar ik ook de meterkast heb dus ik kan de ventilatie voor deze ruimte helemaal apart van de rest van het huis maken.
De cerbo is idd redelijk warm, maar niks geks ten opzichte van andere mini PCs dus dat moet het prima kunnen hebben.
Since the JK BMS is extremely poor at measuring low currents — and consequently the SOC — I use a SmartShunt as the “battery monitor” (for current measurement and SOC determination) while keeping the JK BMS in place as the “controlling BMS”. This works exceptionally well.
Thank you! I printed the entire cover and base. At the ends of the Lynx Power In modules I also printed side pieces to cover the exposed red and black rubber busbar covers.
(I tried ordering filament in the same color, but unfortunately there is a small color differnce)
The difference is almost not visible on the photo, is it apparent in person? Do you mind sharing which filament exactly you used? So maybe someone else does not have to search for a matching color again
I used this one: https://colorfabb.com/nl/light-blue-ral-5012 (I actually got it with a promo discount)
for me it is an acceptable color difference also given the lighting in the room itself
Here is an better image of it, so decide for yourself
Maar warmte gaat een probleem worden, ik heb 3x een mp2 5k met voldoende ruimte rondom in een aparte ruimte waar het in geplaatst is (binnenshuis met aparte ingang, niet zon zijde) heb ik ventilatie moeten inbouwen omdat het zomers 35gr+ kan worden door de warmte afgifte van mp2s, nu met ventilatie is het max 30
It’ll be a bit of a challenge temperature-wise, but a small, inexpensive 6000BTU split air-conditioning unit in the room will sort it out… there should still be 700W power left over as well
Manufacturer’s warranty terms: – Void under all circumstances
In the event of a fire or any other associated risk, any insurance claim will be declined.
Even five air-conditioning units would not make this installation compliant or technically acceptable. I could continue, but I see no point in doing so.
Thank you for sharing your concerns. I’m aware of the temperature/heat/ventilation improvements that need to be made.
I have to work with the space that I have and unfortunately that is not a lot.
I have spoken to my supplier and they said that these units are very robust and can handle a bit of heat. And while not according to the manufacturer’s recommendations, this should be “fine” (but not perfect) as long as the room is well ventilated.
Even now with the heatwave in the Netherlands the units are doing great (the room temperature is about 27c)
That being said I’m definitely going to improve the cooling/ventilation based on some of your suggestions. Any constructive feedback is always welcome .
This is your home, and the first thing that should concern you is safety you live there.
Since you have taken on the role of an engineer, use your imagination and creativity, and thoroughly study all specifications, requirements, and applicable industry standards.
Yes, I understand that you are limited by space and probably have no alternative location for the installation. However, even in that corner of madness, it is possible to arrange everything in a reasonably practical way so that you can live in your home without constantly listening for unusual noises or checking for strange smells.
Here’s a hint: - imagine a chessboard, then consider how to position some of the main modules on that wall in order to comply with the manufacturer’s requirements for airflow and heat dissipation. Next, use the adjacent wall to mount the DC busbar and your control and protection box vertically. In addition, ensure proper cable management so that the AC and DC circuits are kept at an adequate separation distance from one another. And, as the final piece of the puzzle, address the requirement for supplementary ventilation afterwards.
