How much is too much?

I just recently finished building a system in my RV that consists of a solar array (not a part of my problem) 6 100AH 12v Battle Born batteries wired as 300AH 24v, mated to 2 24v 3000w Multiplus inverter/chargers wired in parallel.

My question is how much wattage should I be able to pull from this system when the batteries are fully charged? Currently I'm running into issues where the entire system will overload and spontaniously shut down or just give me an overload warning when I have one A/C unit running (consuming 1400w with 300w to other loads) and I try to use something like an electric kettle, hair dryer or toaster all in the 1400 to 1800w range. This seems very low even if a parallel system doesn't give me a combined 6000w it should be more than 3200-3500 shouldn't it?


Have I wired something wrong? I don't have a colorGX so I only use the Victron Connect app and it doesn't show me that they are running in parallel but they do only show wattage and usage numbers on one unit after I switched to parallel (the switch did not improve my ability to use electricity btw) I've attached a schematic of how I wired my system if it helps. Once the two inverters output their power it's combined at a breaker and then each leg powers one side of my breaker box. I've tried placing the load on breakers on both sides and the issue exists no matter if the load is on the same leg as the A/C or the opposite.

Quattro Inverter in Passthru

Hi There,

I have a Victron Quattro system that goes into "passthru" and then stays there for extended periods of time. I have noticed that this is somehow related to communication with the ET112 single phase grid meter which is connected to a color control gx.

Enabling and disabling the energy meter as well as restarting the color control solves the issue consistently.

Below is a list of components with the current firmware versions

Color Control GX - v2.54

5kVA Quattro - 2657430

Freedomwon Battery Monitor - v6.8

250/70 MPPT - v1.50

3.6kVA Fronius Inverter - 3.13.2-2

Please let me know if I'm missing something.

Best Regards

Multiplus 12/3000/120 Overloads in Charge only

Hi All,

I have an issue with my 12/300/120 Multiplus. When on shore power, and set to Charger Only mode, (majority of time), there have been three occasions now when the unit has tripped to "overload" for no apparent reason.

AC loads are minimal, probably 2-300W, DC loads also low, 3 - 11A depending status of fridge / freezer and any lights on.

I had thought the first time that "UPS Mode" may have been a factor but this has been disabled.

Batteries are 4 x Rolls 400 series flooded lead acid, 130Ah ea. Other Victron in the system currently just the BMV712, with 100/30MPPT and Colour GX controller to be fitted soon.

I can give more detail and photos when I get back to the boat in a week or two, including current firmware, which I know is not the latest.

The unit was not installed by me but already installed in the boat.

Many Thanks.

Hi If I configure 3X15KVA Quattro's to provide 3 phase output, could I use a single phase AC in to convert a single phase supply to a three phase supply?(As long as a I turn off act as group on the veBus config) If so would they convert the 100 amp 230 Volt supply on the AC in to (roughly) a 33 Amp 400 Volt Supply on the AC out.

Multiplus 12/3000/120-50 Ideal Grounding on Travel Trailer

I've spent quite a bit of time researching this question, in the Wiring Unlimited document, along with the Multiplus manual and a multitude of forum postings. I realize some elements of the question are largely redundant so I will try and be as specific as possible. This installation is for a personal RV, and although I'm not a licensed electrician I have done quite a bit of high voltage electrical work, and as a computer scientist have had some exposure to electrical engineering principles and issues when working with microcontrollers, etc, though most of my work does not involve machinery or process automation. I'm by no means an expert, however.


I'm working to complete an installation of 2xMultiplus 12/3000/120-50 inverters connected to a 6x100AH Battleborn battery bank in parallel configuration. I also have a SmartSolar 150/85 MPPT controller connected to 7x195Watt PV panels mounted on the roof. The Multiplus units are in a split phase parallel configuration. Proper size wiring and current protection devices (breakers and fuses) on both the A/C and DC side are installed and various points(E.G. pre inverter A/C breaker, post PV combiner to MPPT controller, post MPPT controller to battery bank, post battery bank pre inverter, pre trailer existing wiring connection, post inverter A/C to trailer, etc). Properly sized wiring is used based on the current protection devices in place and maximum intended sustained amperage taking into account insulation rating, conduit fill rules (where applicable), etc.


At this juncture I have completed the majority of the installation on the system but have come to a question on proper ground application. Currently all equipment functions without grounding the equipment separately to the chassis(although I have full intention of doing so), and I have tested the system in excess of 250amps continuous DC flow to the inverters for extended periods of time(E.G. by turning on the A/C, electric hot water heater, etc). After working through a number of configuration "tuning" issues, I'm happy with the results, although an added element of safety is left dangling out there.


With that in mind, I believe the following is accurate:

1) Each Multiplus should be separately grounded to the chassis using a conductor of equal size to the conductors used in DC +- in the inverter. In my case 4/0 wire with 105c insulation.

2) The Solar MPPT controller should be grounded to the chassis, again with the same principle outlined in 1 regarding wire sizing.

In both 1 and 2, it would be alternatively acceptable to utilize a wire size equal to the acceptable size requirements for the current protection(e.g. for the battery bank a 300AMP fuse is used) device.


This brings me to my question(s):

Currently the negative and positive leads running to/from the inverters are connected to BusBars rated for 600A each. The positive side, prior to reaching the bus bars from the battery bank is fused, and then runs to a disconnect, then to the bus bar. The negative side, through a shunt and then straight to the BusBar.

One of the terminals on each BusBar runs off and connects to the main trailer wiring via the terminals where the previous manufacturer supplied batteries resided and then into the main trailer DC supply disconnect. This minimized the amount of rewiring needed to tie into the existing DC wiring. The positive side leading to the trailer manufacturer dc wiring is fused prior to reaching the existing trailer wiring system.

The existing trailer appears to have ran a frame chassis DC connection from the negative side of the DC wiring. Should I disconnect this and replace it with a larger 4/0 wire from the battery bank bus bar? Is it acceptable to leave it, and run an additional negative wire from the BusBar directly to the chassis(near the existing ground bar on the trailer)? Would/Could this create a ground loop/other situation with multiple DC paths to the chassis ?

Additionally, since the Multiplus requires a ground, should I route that to the negative BusBar, instead of a separate ground out to the chassis, and then use the larger ground noted above? The same applying to the MPPT controller. Similar to this:

https://community.victronenergy.com/questions/25415/installing-the-multiplus-3000.html

In the aforementioned diagram, it would appear all negative and ground connections are terminated on the same negative busbar, and then a single chassis ground is ran to the frame. If that is the more suitable way to approach it, would it be necessary to disconnect the existing DC negative to chassis run the manufacturer installed(I would think so)? How would energizing the inverter chassis with high voltage A/C impact the DC negative connected equipment in the case of a short to the inverter housing using a common busbar scenario(or for that matter into the chassis) ?

I'm trying to determine the most ideal path forward to ensure safety and minimize complexity. The wiring space is extremely constrained as well. Any recommendations are much appreciated.


Thanks in advance for any thoughts.

MultiPlus malfunctioning

I have used my multiplus 12 500 20 for over a year, it's been fine.

A week ago our leisure batteries dropped to 35% and we used shore power to top up. The inverter got too hot and turned off a few times.

Since then the inverter has worked fine, we've charged our laptop several times using 230v.

Today one of our consumer unit breakers tripped, and when turned back on, the inverter seems to be malfunctioning. If I turn it off and back on with no load, the green inverter lights comes on. I can plug in my tester plug to the 230 socket, no problems. If I then plug in the power supply for my laptop (without the laptop attached) the multiplus flashes the alarm light or just turns off.

I have tried checking the sockets-fine, the breaker from leisure batteries to inverter - fine, and plugging in a battery charger to the socket - fine

The multiplus also makes a crackling or grinding sound before it shows the alarm sometimes.


Can I check or do anything else? Or do I need a new one? I have a multimeter but don't know how to use it! I'm in France...


Thanks!

Multiplus 24/5000/120 settings: search mode, max charge current, input current limit

Hi,

I have the above Multiplus, BlueSolar MPPT 100/30, 2x200W/12V serial PVs, 2x200Ah/12V serial AGM batteries, Honda EU2200i generator and have the following questions about three settings:

1. If I have both the search mode and AES switched on, which is over-riding the other or can they work together?

1. For the 400Ah/24V battery set it doesn’t seem possible to set the maximum charge current as low as the generators continuous output 1800W/230V=7,8A. The lowest setting is 25% of something (percentage of what is still unclear? Maybe 100A x 25% = 25A?).

3. The input current limit can only be set to the following values:6,3A (1.4kVA at 230V),10A (2.3kVA at 230V),12A (2.8kVA at 230V),16A (3.7kVA at 230V),20A (4.6kVA at 230V), 25A (5.7kVA at 230V),30A (6.9kVA at 230V), 50A (11.5kVA at 230V). The question is how this setting affects the charging on different loads. It is clear that I should not have this setting to more than the generator’s continuous output power. But is it so, that 1) at no load the genset is charging with current of the setting (e.g. 6,3A), 2) when there is load up until the setting (6,3A), the load will be supplied 100% by the genset and the rest is used for charging and 3) when the limit setting (6,3A) is passed then the load will be covered by the genset AND the batteries and no charging will happen?


Thx.

Under voltage alarm on only Quattro not on BYD

Hello

I had multiple Undervoltage alarms/warnings on L1 Quattro in 3 phase setup out of sudden.

The LOG file shows BYD reporting normal 54.7 V voltage There was a normal load on the system and no overload recorded. The alarms were getting triggered randomly and the log shows wildly fluctuating VE bus voltage

Does the Ve bus take the voltage only from L1 Quattro?

I checked cable tightness in Quattro ( all three phases ) as well as on the LYNX busbar.

Will check later today the breakers and the individual battery module tightness. What else should I check? The system worked for the last 1 year without any major issues.


The system is ONgrid /ESS with 10 KWH BYD pro and 3 ph 5 KVA Quattro with 6 KVA Fronius and 250/70 Smartsolar

Multiplus or Multigrid for off-grid

Hello, I had a question about Multiplus and Multigrid. I am building a small off-grid system with 4 solar panels off 300 watts each that will charge battery's using an MPPT charge controller. I also want a backup generator to charge the battery's if they get under a certain level, and I will be using an inverter to make 230VAC 50Hz from the battery bank. At least I am also using a wind turbine that will give me a peak of 600 watt.

So a short list of items.

- 6x Solar panel 300 watt

- Battery bank

- Multiplus or Multigrid?

- Inverter

- Backup generator


What will be the right choice? Multiplus or multigrid.

And is this a realistic setup? Or is there a more efficient way?

BMS and HE Li-ion capacity messed up after updates

Hi recently returned to the boat which had been on shore for past 10 months (not connected to power). 2x Li-ion HE Batteries (2x200Ah) seemed okey so started updating all systems (Venus GX, multiplus, mppt, BMS400 etc).


I notice in the past week that the battery level seems to be wrong. I reset consumption stats but still at about SOC 60-65%, voltage will be <24.5v indicating it is much closer to empty.

At this 65% SOC level the multiplus also turns off by itself and no longer inverts... again suggesting SOC is wrong!

I am not getting multiple low cell voltages and have no idea how to solve this?!!

CCGX Ethernet Issue

After eliminating the Fronius as a problem (was discoverable on the network) looked at the ccgx and and could not find it on the network. Went to the ethernet settings and found it had generated an IP address starting with 169. Unplugged the ethernet cable from ccgx and plugged it into my laptop and internet worked fine. Then noticed the ccgx ethernet lights were still on although there was no ethernet cable plugged in, i then navigated to the ethernet menu and it said it was still connected. So i did an offline update to the ccgx, it was successful but after the reboot the ethernet lights were still on and it said it was still connected even though it was unplugged.

Advice with ESS system, external control and phase balancing

Hello, i am new on this forum. Professional experience with Modbus/TCP, comms, energy, MQTT and all relevant technologies but new with Victron.

Yesterday my installer finished a larger ESS system for my farm (16 pylontech batteries, 3x multiplus 5000, i have 3 solar production systems of total about 15kw, plus many consumption points to control).
MY ET340 is hundreds of meters from the battery installation (this is a quinta), so i cannot really run RS485. But for fine grain control i rather want to use the ESS system "semi dumb" anyway in that i can just use it as a great battery management system and fine tune/control the carging/discharging of the battery by MQTT or Modbus/TCP.

I see there is Modbus/TCP but the amount of writeable registers is rather small ... and i cannot see how i can command the multiplus inverters separately to draw or produce a certain amount of power (to both use the batteries efficiently as well as to do phase balancing).

Can someone help me with those ?

The Quote does not clearly point out that the same "Type" means it has to be the exact same Product expl. "Phoenix 24-1600"

The firmware is all current and shouldn't have the old limitations. I can't see how to draw deeper in the battery. Please note, this isn't shouldn't be inverter start/stop issue with the known limitation of inverter restart voltage as the load on the inverter is constant.

Bridging AC-Out Neutral with Neutral/GND from Grid Supply when they meet in transfer switch?

Per a suggestion found in a Victron manual, I am looking at installing a manual transfer switch that will switch the Supply Feed going in to my "critical load" sub panel... between the AC-Out of my Victron MultiPlus, and the Grid Supply.


The Manual transfer switch has an isolated breaker that will allow only the Inverter Output L1 or the Grid L1 to be connected at one time to the Load L1. If the Inverters fail, or are being worked on, the "critical loads" can be cut over so they are supplied directly from grid.


The problem I am having, and the question I am asking is: The Transfer Switch has a common bus bar for the Neutral. Is it safe to bridge together the MultiPlus AC-Out Neutral, and what is essentially the AC-Input Neutral in this manor when using a transfer switch?
