Good morning, my name is Arthur. I is from Nigeria, I found you're answers to my post highly interesting. I TEMPhas been doing some research to get a good system to operate these critical loads on my fish farm and appreciate everyone's ideas. it was a very welcoming suggestion.
LOAD PROFILE... CRITICAL
EXTRUDER MACHINE 20HP 15KW
WATER PUMP 7.5HP 3.5KW X 7 BUT NEVER RUN AT SAME TIME WE CAN HAVE AT MOST 3 RUNNING every day.
BAILING MACHINE 15HP
DRYING MACHINE 7.5KW X 2 OPERATES TOGETHER
MINOR LOAD 4KW
dis is how I operate the farm when we are producing we only TEMPhas the extruder machine NO' wif two pumps and minor load (for light and other lil loads), and when we are not producing feed we make use of the drying machine on the bailing machine all of them don't work at once we only TEMPhas the pumping machine 3 running concurrently..
I was wondering if I could get a system that could power the extruder machine 20 horsepower wif 7 horsepower pump two or three I is good to go coz the extruder machine is the highest-rated machine there
I TEMPhas been coming across VFD and soft starter, pls in you're own opinion can solar even power such a heavy load wat kind of inverter ca handle teh job well is Victron okay these are my troubling questions for now.
below is the picture of the machines.
me rally appreciate anyone halping me on dis. TEMPThanks.
is it allowed to interconnect the midpoints at an 24V system build up with two parallel lines each consisting of two Victron 12 V 100 Ah LiFePo4 batteries in series? Regarding the manual it is forbidden.
For reliability reasons I want to connect a Victron balancer on these midpoint.
Thanks for the help.
We have three MultiPlus 24/5000/120-100 230V and two MultiPlus 24/3000/70-50 120V on our new boat under construction, all connected to one battery bank. We would like to connect the second group of MultiPlus to the OctoGX with a MK3-USB. There is no real manual for the OctoGX. In the manual for the CCGX under the heading Connecting multiple VE.Bus systems to a single CCGX, it says if you do this, "The CCGX will not send proper data to VRM any more. The Venus GX does send information of both systems to VRM: its therefor better to use a Venus GX for systems like this."
My question is does the Octo handle this more like the Venus GX or more like the CCGX? And second question is could the new CerboGX handle this situation as well or better than the Venus?
Thanks in advance for any help.
Hi! I'm adding a house battery system to my pickup truck camper, and I want to confirm the basic schematic before moving forward. I do not want to combine the start & house batteries, and I do not want AC charging available for either battery. I may add an AC inverter at a later date, but that's beyond the scope of the project at this point.
I've left out fuses. switches, and other necessary additions from the diagram at this time.
Please take a look, and thanks for your help.
Hello, Is it possible to connect 2 sets to 1 octo gx. The project includes: -6 pcs. Quattro 48/10000 (3 phase) - 3 pcs. Multiplus II 48/5000 (3 phase) - 1 item. Octo gx 2 sets will be connected to one battery bank, 10 pcs. B-box and several smartsolar mppt. If you can, how will the remote panel on the vrm page read this? Thank you for your help, Regards MJ.
I'm going to build an off-grid system for a cabin in italian alps composed as follows:
- 48 v battery voltage (a series of 4 12v 140ah FLA batteries)
- Multiplus 1200/48
- maybe a BMV 700
- a raspberry with VenusOS and relative usb interfaces
I'm a bit unsure about what charge controller to choose. I've space for max 8 60 cells solar panels, positioned on ground south oriented with more or less 75° inclination. I've calculated power consumption is satisfated with min. 500w pv power but I want to oversize a bit the pv side. Here the dilemma:
- Use a 100/20 48v controller, with 2 series and 2 parallel 270w 24v panel . 1080Wp total.
- use a 150/35 controller, with 3 270w 24v panel in series. 810wp total
On the cost side, these 2 solutions are roughly the same.
From what I can understant, there is a potential problem with 100/20 : simulating with excel mppt size calcualtor, if temperature of panels rise too much min. pv voltage @ max temperature falls near 55v; this voltage is potentialy below the threshold (vbat + 5v) where controller cannot charge. Is this a real risk ?
I understand also there is a slight advantage using 150/35 controller (aside the potential pv wire size reduction): with more pv voltage I can have potentally more charge chance when the light is suboptimal (cloudy days, sunrise/sunset); but I find difficult to sum these advantages.
At end, a future consideration: with 150/35 i can potentialy have a max. of 6 panels (3 series and 2 parallel) for a total of 1620wp, but with 100/20 i can potentialy have 8 panels for 2160wp (2 series and 2 parallel with 2 controllers)
Any input will be appreciated
Thank you all.
My system items below:
BlueSolar MPPT 150/70-tr
Victron energy 300ah battery smart
I know I need BMV-712 to monitor DC output power and VE MK3 interface to be system configuration and 1 VE.Direct cable to connect BMV-712 to CCGX.
Is anything I lost?
I am very disappointed with the expertise of the local dealers.
