Settings for 100/50MPPT

I have a MPPT 100/50 connected to one Renogy 200ah Deep cycle Pure Gel Battery. I need the correct settings for the rotary switch. The controller is connected to 4X100W solar cells which are connected in parallel. Would appreciate any help. Thanks in advance

Both controllers are working fine at ''Bulk' and ''absortion'' mode but one stop working at ''Float'' mode, Why?. Both controllers have version 1.39. I noticed that one controller blink every 3 second at ''bulk''mode, Why?

Hi!

I have a 48v install with s2p2 24v smart LFP battery with a Quattro connected to it. I have almost 3000 data points in VRM and see that the voltage never goes above 54.5. With other installs I see that the voltage goes to absorption where the cells are equalised by the BMS.

Also, maybe it is unrelated but I can't seem to connect to the remote console, although I am almost certain that I have enabled the feature.

Any suggestions?

Hi,

My BlueSolar MPPT 75/50 (v1.12) has been working for many years, I recently connect to my laptop and VictronConnect, it detected a new firmware v1.39 and I have to upgrade to continue using VictronConnect.

I upgraded the firmware but now charging staoped and there is a error on Victron software "#116 Lost Calibration Data" its not working anymore. Bulk and Absorption LED flashing blue simultaniously.

I down loaded v1.43, upgraded but still same issue.

Can anyone help revert back to the original firmware v1.12 please, my device is 6 years old so cant send back to dealer.

Any help will be appreciatded.

1- What is the exact charge voltage temperature correction coefficient programed into a Multiplus (as default)?

I can't seem to find this documented anywhere, apart from the graph in the appendix pages at the back of the manual. Based on this graph I have roughly calculated it but would like to confirm 100% - as the graph may only be pictorial.

2- Is there any way to update the Multiplus charge voltage temperature correction coefficient?

I have had another look in VE Configure today but couldn't find a setting to configure it.

Thanks in advance, Mark.

I have just got 3 X Victron 150A Smart Lithium batteries. I was advised to initially pre charge them with a Blue smart 12V/15A charger, set to lithium and charging at 2 amps. Charging the first battery, went fine and ended with 13,44V and all cells at 3,36V stating "Ready for use". The next battery got to 14,06V and stated "Busy, charging disabled" and cell voltage at 3.90V 3.38V 3.37V 3.41V. After removing the charger, all cells next morning was on 3.32V and stated "Ready for use".....The last battery done just about the same as number 2............What am i doing wrong or is the 2 out of 3 batteries faulty?

Hi All,

I am hoping to learn from others and also to find some peace of mind that I have correctly set up my new Victron Connect system. Any thoughts much appreciated.

This is my set up:

• 4 x 110AH AGM batteries (house bank)
• I have 2 x 110w solar panels wired in series
• 1 x 100/30 smart solar MPPT charge controller
• 1 x BMV-712 smart battery monitor

These are my current victron connect settings for my battery monitor and also for my mppt (no sun in Greece today and so I've just put my 50Amp battery charger on!)

A few of the other things I don't understand. Sorry!

• Why does the 'State' say open as opposed to Bulk/Float?
• Shouldn't it be charging at 14.4V as opposed to 14.2V?
• What should I be doing with regards to 'Synchronising SOC'....'Zero Current Calibration'...& 'Manual Equalization?'

Many thanks

Alex

I have turned on MQTT on my CCGX and I am able to subscribe and get messages. I want to be able to change the generator start/stop rules which are based on the Battery state of charge. They are current at 50% and 70% but I want to be changing them programmatically depending on forecasts. Does anyone know the topic to publish to so these values could be changed?

I have EasySolar 24/1600 and I have same problem like this EasySolar ESS randomly switches charging-discharging mode. This problem is only in ESS mode, in HUB1 mode works stable and without problems. The problem occurs, when it is broadcast remote command on the 216,7 Hz. Tone frequency 216,7Hz is superimposed to mains during broadcast remote commands. This tone frequency is used most of the region in Czech and Slovak Republic.

Is there a way to configure a high voltage cutoff the Smart MPPT 100/30 uses to prevent surges from causing charging voltages beyond specs of battery? I recently got a Gel battery and they are sensitive to high voltages. My charger gets voltage/temp from my BMV battery monitor, however sometimes it misses bluetooth voltage update packets, and on intermittent cloudy days, there can be sudden surges in output current, but if the battery is mostly full already, the voltage will jump as high as 14.85 volts before the MPPT finds out and can back the current off to maintain the 14.2v it should be. Is there some kind of protection setting that can prevent this? This was an expensive battery and I dont want to damage it,

Hello from the USA.

I see the Canvu Extender needs 8-32vDC to function so if the battery is 48vDC nominal, can I use the Orion ORI482428110 isolated DC-DC converter to whack the DC voltage in half? OR: will the Canvu think we're running a 48v Quattro from a 24v battery & throw an error?

Assuming that the input voltage does not inform any Canvu measurements but only powers up the Venus device...could I also use an AC to DC converter to get a steady 24vDC for that purpose?

Thanks in advance, community folks~

Does Multiplus AC Out 1 and AC Out 2 share the same Neutral? Are the bonded together and is it a problem if I wire the neutrals together and AC2 Out is tunned off? I don't want to make my campfire inside of RV. haha

Installing MP 3000 in a 5th wheel. Confused over gauge of wire to use on chassis ground lug to RV frame? Have read where it should be same awg of "conductor" wires? Think abyc standard specifies so.

I'm using 4/0 battery/inverter DC cables and have 400ah battery bank (lithium).

What chassis ground wire size is correct?

I am looking at implementing an 'intelligent' energy harvesting system using a recently installed system that has PV array and a Pylontech battery bank and the above plus a mppt 150/70, that is to use a certain/calculated amount of stored energy in the evenings, and then restore that with PV sourced electricity via the mppt 150/70 the next day. I have made a seperate contoller to do this, that can monitor the SOC from the Pylontech bank via CAN Bus messages, so that once the SOC quota is used it will go back to AC power. I will activate the Inverter by an external transfer switch to disable the AC in and that will get the Inverter on line.

What I don't want the Inverter / Charger to do is use the main supply to charge the batteries automatically when it comes on again, that will be done by the PV the next day, I know one can switch off "Enable Charger" in the VE Configure but I want to be able to do this via a control signal or software command to the Venus or the Quattro everyday and can't seem to find any way of doing that so far.

I would appreciate any information in this regard.

One way of doing this is to switch OFF the Inverter by the remote control which is easily done but then there would be gaps in the data on the VRM portal since the Quattro monitors the main feed in terms of power supply.

Thanks in advance.

I recently bought to my existing system a Victron SmartSolar Charge controller MPPT 100/30. The idea was to replace the old controller with this one. Well, now when I wanted to install it I noticed there's no incoming place for the cables going to the load (lights, usb and so on). In all the controllers I've had before there's been incoming connectors for the battery, the panels and the load. So sorry for not getting this, but how do I do this, what is missing?

Hi,

I have a B&G Zeus 12 from around 2012 and a new Victron Venus GX. Can I connect the Venus to my plotter to show the data, like you do in this video? https://youtu.be/RWdEQfYZKEs

Multiplus.II 3kw .. connected.. 4kwh blue Nova Battery. Inverter switches on and off.

Fault report on the Portal: Internal Error.

I have a BMV 712 that is not working. It hung up on install with the firmware upgrade. Subsequent firmware upgrades fail. Shunt seems to work, but 712 doesn't register or give an LCD messages. Just jibberish. Other Victron equipment did update successfully. My dealer (I am in the U.S.A.) has not gotten me a replacement unit as promised and after 3 weeks I'm getting frustrated with the warranty/replacement process I do not know if it's Victron or my Dealer who is at fault and don't care. Just want a replacement. How do I resolve this other than ordering a new one and putting in a credit card or paypal complaint?

Hi, I get a connection refused error when trying to connect to https://docs.victronenergy.com/vrmapi/overview.html

Any reason for this? Is the page still valid?

What are the dips on the Solar Power Yield Graph? This is on a clear sunny day with no cloud.

My Multiplus 3000 puts out a max of 66 to 70 amps in charger mode on generator even though my batteries are down 240 amps.

My battery bank is 630 amps - 12 v

When connecting the programming I do not get the choise "d" to change voltage as described in the manual. I only get a,b,c

I need to change from 12 to 24V

What to do?

The VE BUS is giving a low battery alarm while the battery voltage is normal in the BMS. See picture below. There was a high current draw event and after the VE BUS voltage started swinging low when the inverter mode kicks in. Any ideas how to resolve this? The system is a split phase with 2 Quattro's and BYD battery bank of 7.5 kWh.

The diagram for the Cyrix-Li-Load shows an emergency override switch. Is there a way to do the same on a Smart BP-100?

In installations where there is no BMV, with CC GX installed, you only see the value of the SOC in the Color Control that rescues this value from the inverter. We know that the inverter is far less accurate than the BMV. In the inverter we configure the battery monitor section to show the correct value. We also find it odd that when this value is set, the screen shows 100% battery, knowing that the batteríes are not 100%.

We would like to know for this kind of cases that we can do so that the client has a reliable % SOC measurement. Especially when there is no BMV installed.

I'm designing an off grid system and I'd potentially like to use a Phoenix Inverter Smart with a Victron Autotransformer. The photo below is what I want to do:

[image]

My question is where should I attach the ground relay control (shown above) and is this setup compatible with the Phoenix Inverter smart?

From the Victron Autotransformer manual (page 3), I see that,

[image]

From the Phoenix Inverter Smart manual (page 9), I see that,

Since the system is in a vehicle does that mean I simply need to connect the ground relay control wire to the same ground as the inverter?

Thanks for your help and let me know if you need any more details!

My travel trailer PV system components: Multiplus 3000/24/70, 4 S6-275 AGM Rolls batteries. I am planning the install of a SmartSolar MPPT 100/50 and 2 JKM365M-72-V wired in series.

PV specifications

The SmartSolar 100/50 manual states:

3.2 Grounding

● Battery grounding: the charger can be installed in a positive or negative grounded system. Note: apply a single ground connection (preferably close to the battery) to prevent malfunctioning of the system.

● Chassis grounding: A separate earth path for the chassis ground is permitted because it is isolated from the positive and negative terminal.

As my Multiplus is grounded to the chassis, I would ground the MPPT case to the chassis as well, yes?

● The USA National Electrical Code (NEC) requires the use of an external ground fault protection device (GFPD). These MPPT chargers do not have internal ground fault protection. The system electrical negative should be bonded through a GFPD to earth ground at one (and only one) location.

As this is a mobile application, is a GFPD required?

If so, this appears to be the proper device.

[image]

● The charger must not be connected with grounded PV arrays (one ground connection only) You would still bond the PV framing to the chassis, yes?

3.3 PV configuration (also see the MPPT Excel sheet on our website)

● Provide a means to disconnect all current-carrying conductors of a photovoltaic power source from all other conductors in a building or other structure. I take this as a 150VDC / 20A breaker on the positive leg between the PV array and the MPPT and a disconnect on the negative leg between the PV array and the MPPT?

Apparently to Code, the GFPD must not be used as a disconnect. Should the GFPD be wired before or after the PV array Pos. breaker and Neg. disconnect?

● A switch, circuit breaker, or other device, either ac or dc, shall not be installed in a grounded conductor if operation of that switch, circuit breaker, or other device leaves the grounded conductor in an ungrounded state while the system remains energized. Is this in reference to an "uninterruptible" ground to chassis?

In all my research to date, this is the first time I heard of the requirement of a GFPD. Never heard of it on YouTube PV installs.

Any input would be greatly appreciated.
