Your evaluation before installation

Hi Folks

Before installing my system in my motorhome, I wanted to submit to your experiences on this installation.

The green part is the support panel. The cables pass through the rounds to pass to the rear. This forms like a door with a hinge to facilitate assembly and to carry out subsequent additions of elements. The dimensions of all elements are exact dimensions in mm. The thin cables are in 2.5mm2 or VE.Direct or USB, the medium ones in 16mm2, the batteries in 35mm2. The battery fuses are 175 ANL. The red lines are + or Line or Phase, the black lines are - or Neutral.

No cables cross and the support panel is 80 cm x 60 cm, made of fireproof wood. Did I miss something in this assembly diagram?

I thank you in advance.

3 ph Multiplus 2 Erratic behaviour

I have attempted to explain my predicament below. Apologies for the long story, but struggled to abbreviate and still ensure I cover everything I have seen thus far.

I have a 3ph system with 3 Multiplus II 48/5000, a Cerbo GX, three MPPT 250/100 and Pylontech US3000C battery system. I have also installed an EM24 grid meter that is connected via USB to the Cerbo GX.

I have installed approximately 20kW battery power and 13kWp between the three MPPT's.

The system seems to record incorrect data and this causes an erratic response. The EM24 seems accurate. I have a 6kW 3 phase element in the one geyser and can see when this comes on that the EM24 shows an accurate reflection of this power as can be seen in the picture below.

[image]

During the past hour the element was on while the MPPT's was charging the batteries. Midway though the time where the element was on, the system decided the batteries is sufficiently charged it can assist. As expected the grid will now reduce while the inverter is pushing back the power to the non-essential side on the AC Input of the inverters.

The concern is that AC Consumption (Total load calculated by the system) now spikes to almost 40 kW on L1 as well as on the other phases although little less. The grid meter is actually seeing that we feeding back into the grid on L1 and L2 although L3 remain stable (L3 now correctly replaced with the power from the batteries). Also the Multiplus AC Output power becomes extremely erratic, which I would believe is only the supply to the essential side and should not reflect the power drawn by the element.

Then as soon as the batteries go back to charging the system become stable again with the Grid meter showing the drawn power.

I have disabled the Grid feed-in (Both AC and DC) settings last night which seemed to have improved the situation, but it was still not stable this morning when the geyser switched on. Below is a graph from 3am to 6am

[image]

At 4am the geyser switched on and the noise started as the batteries still had capacity. Just before 5am the batteries got to minimum SOC (35%) and it started pulling from the grid. After noticing this I decided at 5am to change the Multiphase regulation back to all phases. This improved these peaks and dips seen on the both sets of graphs, but the issue still remain when the batteries are being utilized.

If anyone can give me some advice as to what to look at to improve stability during these discharging cycles of the batteries. Once I have this improved I would go back to Individualphase regulation to ensure I remain net positive on each phase as I have three single phase meters for my 3ph supply that I need to manage.

Thanks.

OCTO GX - 4 BlueSolar MPPT - system voltage issue

Hi there

I have 2000W solar through 4 BlueSolar MPPT's 3x30 1x60amp with VE Direct cables to my Octo GX, also connected is my 12/3000/120 Multi.

Batteries are 2x RB300Ah Relion lithiums.

I have a BMV712 smart also connected to the Octo via VE Direct.

I am having the same issue as many with the MPPT battery voltage being different to the BMV voltage, I can see my controllers going to float as low as 70%SoC.

I have been told if I instal a Bluetooth sensor to the battery bank and network it to the BMV712 that this will become the default voltage for the entire system, has anyone done this with an Octo or can confirm it is correct.

TIA

Using a charge/inverter with lithium ion

Hi,
I'm starting to design a system for a camper I am building. I am looking into using the Multiplus 24/1200/25 with a Lithium Ion (NMC) battery and I have a lot of questions.

1) For the software, looking at the voltage range the inverter should work with the battery (with a BMS of course). I would rather not have the BMS do the load switching except in extreme conditions, or double failures. It seems like these systems have a lot of configurations but I just want to make sure that things like under voltage shutoff, and charge voltages are all configurable as it isnt clear in the data sheet which settings are configurable. Also I have seen some reference to needing a password to change some of the settings, is this this case?

2) The data sheet says there is a "battery temperature sensor", can this be used to disable charging when the battery temperature is too low? My BMS has this ability, but again I would rather have the inverter switching the load. My BMS will allow charge current between 0C and 45C, so I would like the inverter to only allow charge between 5C and 40C.

3) Finally a common problem I have seen when integrating lithium batteries with inverters in the inrush current welding the contractor on the BMS or damaging the FETs, do these inverter chargers have any pre-charge circuit, or other way to limit the inrush current?

P.S. Is there a programmable shutoff voltage for the Orion 24/12-70? If not can I use the remote on/off with the inverter/charger?

System Alarm Grid Lost

For a few days now we've been getting a system alarm that says "Grid Lost." I can highlight it on our CCGX screen, but it doesn't go away. (I.E. The warning triangle in the top of the screen keeps flashing no matter what I do.) It also does not register on the VRM site under Alarm Logs...

We have not lost grid power once in this time period.

I do however use the CCGX's relay and it's automatic Generator on/off rules to tell the Quattro when to pull power from the grid. (I do this so we can use the energy stored in our batteries first.) So while the Shorepower meter shows zero, we are still connected to the grid.

We also have a PV inverter connected to our Quattro's 230v output, which gave me a grid error once, but I've not seen that happen again. (Meaning it might have but then went away before I noticed it...)

Did something change in the firmware to cause us to get this alarm?

We were running 2.51 but it also happened when I updated it to 2.52.

Thanks to anyone that can help!

Is there a System diagram example for boats?

Good morning,

I am looking for some system diagram examples. Our boat has:

* Two engines, with alternators and starter batteries. Separate charger for the two.

* Multiplus 12/3000 with a house battery.

* GX display, battery monitors, etc...


Specifically what I want to improve is charging from:

* either (in case of failure) or both alternators to starter and house battery. Optimally, I would prefer the starter batteries to be charged first.

* solar

* Multiplus. It already charges the house bank, can I use its extra trickle charge output for the two starter batteries with a Citrix combiner?

Naively it feels like there should be individual charge controllers for all batteries? Diagrams I have seen put in protection for a lithium house battery, but not for starter batteries?


Looking forward to getting pointers to similar installations.


thanks,

Addition of Orion Smart DC to DC Charging

Here is my configuration thus far: LiFePO4 House bank, AGM (or SLA) Start Battery. Alternator is 120A non-smart (one option considered is the Balmar retrofit kit but cost is more than the Orion Smart DC Charger) The House was an AGM bank before and both batteries were connected through an electronic battery isolator for charging (diesel engine alternator and shore powered charger and Solar MPPT).

I've read that it may be advisable to keep the Lead-acid start battery from a starting CCA capability AS WELL as a safety consideration -- should the BMS ever disconnect the LiFePO4 bank (over or undervoltage) and say the engine is running, I am concerned the alternator could burn out or excess voltage be pushed through my DC system, damaging electronics.

Since I will have to disconnect one bank from the shore power charger (it can only be set to Lithium or Lead Acid charge profiles) I was wondering if the Orion Smart Charger would help to provide Alternator charging to the House bank through the Start Bank.

The rationale for leaving the Lead Acid connected to the alternator is that 1. Serve as protection from overcharging as it is cheap(er) to replace, 2. the chemistry prefers to be at a higher SOC and can sustain higher/longer levels of charge should we motor for longer periods.

Thoughts? I've seen others who charge from house to start bank. Or is there a product that provides 2 bank DC to DC Charging (using different charge profiles)?

System Power displayed on GX does not balance

I have a system with a Quattro and Solar Charger. All loads are connected to the critical load output. No energy meter. The power as displayed on the remote console does not balance:

E.g. now:

Grid feeds 802 Watt

Loads draw 568 Watt

Batteries draw 120 Watt

So where is the other 114 Watt?

Questions regarding buck-boost integration with CG controller and how/where does buck-boost sense battery voltage

I have 3 questions below.

1. Does the buck-boost integrate with the CG controller - ie will the charging from the alternator that is controlled / facilitated by the buck-boost show up on the energy summary inside the CG controller or is it simply assumed to be a "DC load"?
2. Is there a way to change the settings of the buck-boost using one of the Victron components or do you have to use a windows computer and a USB cable to do so? Specifically, I would like the ability to increase the maximum allowed charging from the buck-boost in case of higher than normal demand for a short while and then change it back. Ideally this would be accomplished through the CG controller and not a windows computer.
3. Where is the buck-boost output voltage (item 20 in the configuration screen) sensed? Is it at the output terminals of the buck-boost or at the battery. For example, I want to place the buck boost in the engine compartment next to the alternator and use the buck-boost to increase the voltage to 24 volts to charge a 24 volt Lithium battery. The cable run from the buck boost at the front of the vehicle to the battery in the back would result in a .4 volt loss along the cables when charging at maximum charge rate (and a small or zero voltage difference at low charging rate). Would the battery receive the voltage set in the buck-boost configuration (item 20), or would it see .4 volts less than this value? If the buck-boost does sense battery voltage and not output voltage, how is this information sent to the buck-boost?

Adding extra MPPT and Inverter to EasySolar 24/3000

Hi Everyone, this is my first post here, hopefully, I can find some answers to my questions, any help is appreciated.

I am looking at installing an EasySolar 24/3000/70-50 MPPT 150/70 as this seems to be a very economical system to get started with, but am wondering if it is possible to expand this system easily in the future or not? as this will determine if I go with this initially and then expand as required later, or, use independent components to allow for easier expansion later.

Will it be possible to add another MPPT, and, of a larger size? - Blue/Smart Solar 150/100 for example.

Also, is it possible to add another inverter? - A Phoenix 24/3000 for example.

Cheers.

Complete system architecture for campervan (640W solar + 320Ah battery)

Hi,

I am currently converting a van to a campervan and I am currently designing the electrical system. My estimation for a full day consumption is around 250Ah @12V. I was considering installing 640W of solar panels with 320Ah of battery. But to ease the initial investment I want to be able to initially install only 320W of solar panel and a 160Ah battery.

My requirements are in line with the general requirements for this kind of application, batteries to be charger by solar power, shore power and alternator.

After some research on Victron website I got this list of critical items:

Initial setup:

  • 2x 160W-12V Mono 1480x673×35mm series 3a
  • 1x LiFePO4 battery 12,8V/160Ah - Smart
  • 1x SmartSolar MPPT 150/45
  • 1x MultiPlus 12/3000/120-16
  • 1x VE.Bus BMS
  • 1x Smart BatteryProtect 12/24V 65A
  • 1x Cyrix-Li-ct 12/24V-120A combiner
  • 1x BMV-712 Smart

Upgrade:

  • 2x 160W-12V Mono 1480x673×35mm series 3a
  • 1x LiFePO4 battery 12,8V/160Ah – Smart (in parallel with the first one)

Any advice regarding my setup?

  1. I considered the use of a Multiplus instead of a charger + inverter, is it the recommended approach for this kind of builds?
  2. Are the monocrystalline solar panels recomended for this kind of application instead of the polycrystalline?
  3. Is there any component on this list that is optional for this kind of setup? Or any critical component that I missed out?
  4. Can I mount to lithium batteries in parallel, considering that they will have different characteristics? The second one could be bought years after the first one.
  5. Is this setup valid if I use AGM batteries instead of lithium batteries?
  6. The use of only one smart battery defeats the purpose of a BMV-712 Smart? Is the same information available is a connect to the Bluetooth of the battery?
  7. How can I extract the raw information of all these devices to a server running in the van?

Thank you.

On VRM the remote console display: ve.bus error #3 and system status "off". If our customer switch on his diesel generator, then the system run properly. If he switch the generator off, then the system shut also off.
