Lynx Power In really 1000A ?

The Lynx Power In, like the Distributor, are advertised with an intensity of 1000A. Without going into the technical details of scientific calculation, we take an average of 1.2A per mm2 (maximum of 3A per mm2 according to the calculation bases of one of the 3 world leaders in professional electrical boxes and safety for busbars). However, the two Lynx have a bar of 30 * 8 mm. This gives 240 mm2. We multiply by the technical average of 1.2 and the result is 288A, or by the maximum of 3, the result is 720A, but never the 1000A. Do you have more information to send me on this subject? Thanks in advance.

MPPT 150/85 shows voltage but doesn't see current / wattage and doesn't charge

I need some advice. I have a MPPT 150/85 MC4 unit. I recently set this up and I have three banks of 4 panels in series (100w / ~18V panels). The charge controller is brand new out of the box (albeit in storage a few months) only opened a few days ago. All functions seem to work on the controller itself.

I've done my due diligence with the wiring, polarity, and confirmed each bank of panels has the expected voltage. Here's the report and I can produce the settings file for anyone if that's useful. VictronConnet_report.log

It's 9am on a sunny Saturday here in Arizona. I'm seeing 73-90 volts and no current or wattage. The batteries are calling for a charge (12VDC, bank of 4 - 6 V flooded batteries wired in series parallel). I've even reset my settings to default and even reset the unit (disconnecting all input, using battery disconnect switch I installed in the battery bay).

Did I miss something? The panels work. The CC works. The batteries are new and working to produce power for the 12V system with no issues. I've scoured the manuals to see if I missed a step but I don't see anything that I missed.

Did I get a dud? If so, how do I get support from Victron?

Orion DC-DC overheating

My Orion Tr Smart 12/12-30 Charger runs hot, and the output current folds back considerably. Anyone else with this problem? When cold, it will output 33A. When hot, it will fold back to 26A or less. Parts of the case may exceed 134dg F, in a cool (60dg F) environment. By adding a 80CFM fan above the fins, the case temperature is lowered by 20 degrees F, and the unit will continuosly output 30A. It would appear that the heat sink is undersized. Comments?

BMV700 current showing high discharge

This installation is on an electric vehicle. This is the second vehicle built and the first one also had a BMV700 installed.

It has 12 AGM 12 volt batteries arranged in 4 banks of 3 for an output of 48V.

The problems are the voltage reads several volts (around 3 volts) lower than the actual battery voltage, and the current on the monitor read -799A.

The amps will change when I turn on the rest of the system, but it only fluctuates down to about -729 amps.

Battery power goes to an unswitched fuse block, 1 amp fuse to the shunt positive.

Shunt is connected to battery, then out to main contactor.

I am just looking at the system without turning on main contactor.

Battery voltage is 53.8V (read with multimeter), and BMV700 reads 50.6V.

Amps read -799.

Losing Amps??


I have an off grid fixed system with no AC in, connected to 4 battleborne batteries in parallel to a Lynx Power In. Its about 9 feet (2 feet using 2 AWG to Lynx then 7 feet much thicker 4/0 AWG) from the actual batteries to a Multiplus 12/3000/120.

When I look at the display for the inverter inside VictronConnect software app under "current" for the AC OUT it will display around 1amp, but under battery "current" it will say from 5-7amps.

Is this actual loss? And if so is that a normal loss rate?

I have networked my MPPT, shunt, and inverter. And I'm pretty sure all my settings are correct BattleBorne guided me through it.

Three phase Quattro 10K 208V/120V system does not use the full capabilities of a generator

Three phase Quattro 10K 208V/120V system does not use the full capabilities of a 100KW three phase generator.

We have SIX (6) Quattro configured with 9 SmartSolar MPPT and a large 1400Ah battery with REC-BMS. The system is configured to use Gird in AC-IN-2 and Generator in AC-IN-1. We also have ESS configured.

In the VE Configure 3 software the AC1 and AC2 inputs are configured to its maximum of 100A. Each Quattro has a 100A breaker going into a 3 phase load center, and the Generator feeds this load center with up to 277A per phase.

Having 2 Quattros per phase should allow me to feed in from the generator 95A per Quattro. But the system is doing a max of 100A total, I thought that the VE Configure 3 tool was configuring each individual Quattro and not the whole system.

How can I get my system to use the most out of the generator?

Orion-Tr Smart 12/12-30 Outputs Less Than Half Amps on 55% SOC LiFePO4. Why?

My Orion-Tr Smart 12/12-30 Isolated is outputting half or less of its rated amperage to my battery bank, and that amperage falls over the course of a few minutes. With its current performance, its not enough to cover my DC refrigerator (15 amps) and charge the battery bank while I'm driving. What could be causing this?

Here's my setup.

  • 2017 Toyota Tacoma w/ tow package (130 amp alternator) & travel trailer
  • Two 100Ah Battle Born LiFePO4
  • 6AWG positive and negative wires from starter battery to Orion and from Orion to batteries.
  • Orion S/N 2048 (appears to be post rev. for overheat changes)
  • Settings: Set to "Charger", Default LiFePO4, Smart Alternator, default vehicle shutdown
  • Installation: Open air, 70°F ambient temperature, in upright position
  • Victron SmartShunt


With the truck at idle after 2 minutes, the voltage at the starter battery posts is 13.5v. Input voltage to the cold Orion shows 13.1v. Cold Orion output voltage to the batts is around 13.5v.


Output amperage of the cold Orion as read by the SmartShunt starts at about 18 amps, well below the rated 30 amps. Battery SOC is only 54%. Vehicle is still at idle speed.


Over just 10 minutes, the output amperage slowly falls to as low as 12 amps. At this point, the Orion is barely warm to the touch.


This occurs regardless of engine speed. The following video shows the low amperage output over time even when the engine speed is held at 2600 RPM. High RPM starts at 00:30 in the video.

Likewise, the input voltage to the Orion remains at 13.1v despite holding the engine speed at 2600 RPM.

Where should I begin looking to determine why the output amperage is less than half of rated amperage?

Amp Draw During Use for Orion-TR Smart 12/12 30A charger

The Orion-Tr Smart 12/12 30a charger is installed in my battery system with a monitor on the load. When I start the vehicle engine with the house battery load at zero, the battery monitor shows the house battery load immediately increasing by 1.5 to 2 amps (give or take). Does this simply reflect the power needs of the Orion-Tr charger while running? I am just trying to explain this load so I understand, and it makes sense that the charger is using power to run itself. Not sure why else the monitor would register that extra couple of amps while the vehicle is running and the Orion device is in operation.

Although, one thing I do not understand is that the Smart DC/DC charger is not connected to the monitoring shunt, but rather connected to a separate post on the house battery. I thought that meant that my shunt (and monitor) would not be picking up on any power used by the Orion DC/DC device. Maybe I just don't understand how the shunt and monitor are working...

Smart Blue Power IP22 Charger: Connecting batteries and charging

Dear All,

I have a Smart Blue Power IP22 Charger 24v/16amp for my boat engine. I need to charge a 24v system consisting of two AMG 12 batteries (vestus marine batteries). The batteries were delivered with a voltage of each 14.2 volt and the system showed me (using a multi-meter) 28.x volt. It is my second pair of batteries having just lost the first once (chronically discharged).

Now, as I have used the new battery a bit, it shows me 24.6 volt, meassured with the multi-meter. When I connect the Smart Blue Power IP22 charger and look into the App, it says 28.x volt, but 0.0 amp., So, I'm afraid I have connected the chrarger wrongly or that it is broken (?).

Unfortunatly, the guideance in the manual is not sufficient for me as it only shows the side of the charger, not the batteries. As I was unsure whether I have connected the system in the right way, I changed the connectons, but the system still showed the same values. I would have expected that it would show me an error if I connect them in the wrong way (?).

Through this questions may not be difficult for most of you, I'd be glad to understand whether we should already see amps flowing, or should this only happen when the batteries has reached a discharge below 24v? Can I find better information on how to connect the system and is the above written (connection in different order does not change anything) an indication that the system is defect?

Thank you very much!

It’s not as easy as just subtracting solar production minus ah of the bmv because it resets everyday (or it’s just cumulative day by day). I installed the Venus gx thinking it would show a graph for each day ah used and solar production per day but no.

Smartshunt 500A/50mV - Amps too low by approximately 50%

Hi everybody,
I hope you can help me with this.
I am upgrading the electric system on a Rapido 9083DF from 2007 which I bought second hand in 2019.
The system is factory-wise equipped with a CBL DS520-distribution block. When I bought the vehicle, two parallel 110Ah sealed lead-acid batteries had already been installed, which I have not changed yet.
I first of all upgraded the system to a total of 480Wp solar panels connected in series with a Victron MPPT 100/50.

I now have also equipped the vehicule with a Victron Orion to recharge the batteries while driving if weath is bad and also the new SmartShunt 500A/50mV to monitor battery activity. The plan is to replace the existing battery bank with 200Ah of Lithium, when the existing batteries are dead.

I also have a 1200W pure sinus inverter installed.

I checked and rechecked the wiring and it is correct. All negatives, including the negtive to the second batterie are connected via a distribution box after the load connector of the smart shunt.

I have callibrated the SmartShunt with the negative load cable disconnected. So far so good.

When I charge the batteries however either via the MPPT or the ORION, with all loads turned off (physically pulled the plugs on the distribution block and the other Victron charging devices turned off and the inverter unplugged) the amperage and watts dilsayed by the Shunt is approximately 50% lower than it should be (compared to what the MPPT shows as amperage being delivered to the batteries).

The MPPT delivered 20A at 9,,8Amps (according to Victron connect) , but the shunt only displayed 4,8 Amps.

The same holds true when I put a load when discharging and turning all charging devices off. The amperage and watts drawn from the batteries are approximately 50% less than what it should be.

To test, I turned the inverter on, connected a Watt-Meter to the plug and put my Laptop on in video mode. The watt meter showed a steady consumption of approximately 60 watts. Accounting for losses du to the inverter, I estimate that the draw would have been 70 watts or approximately 5,8A. The shunt displayed only approximately 3 Amps of draw.

During a discharge test, with approximately 8Ah of the Battery, the Batterievoltage dropped to 12,05 (after turning all charges off and waiting for 15 minutes), or 50% DoD after approximately 15hours of discharging, However the Shunt claculated 81% SoC (or 19%DoD).

I am at a loss to what the problem could be. Any ideas?

Thanks in advance

Victron 3000, 30 amps vs. 50 amps, Shore vs. Solar, Batteries not charging when off, of course

New to the group. To lay the groundwork for the question:

  • We have a 50 amp fifth wheel.
  • We bought the unit used from a private seller, very happy overall.
  • The solar / Victron was installed by the seller or he had it done.
  • We have 4x Battle Born 100ah LifePo4, 4x 190W solar panels, 2x MPPT, SmartBMV and the Victron 12/3000/120-50
  • We (the wife, the dog and I) are fulltimers, three months now!

We have been, in the past three months, mostly on shore power, and always on (confirmed) 50 amps. We found that one of the monitor panels (not listed above) showed us at 30 amps continually. Reached out to seller, he indicated that if I had the inverter on, I'd be limited to 30 amps. Turned it to Off, and I'm back to 50 amps and I can run the air conditioners. Excellent for the Texas heat we'd been dealing with.

Two days ago, we relocated to a park, and were fortunate enough to park in the shade. Sure, solar will be very much reduced, but that's okay: we have 50 amps.

Tonight...the generator kicked on. Turns out we ran down the batteries to 50%. Direct DC usage in the rig, like lights, whatever else is straight DC, ran them down. With the Victron set to off, the shore power doesn't recharge the batteries. If I turn the Victron to just "Charger" (not Inverter), it will recharge the batteries, but I will still be limited to a 30 amp system.

This feels wrong to me. I'm a programmer, have been for 30 years. I'm decent at debugging, but I haven't examined all the the wiring and gotten a deeper understanding of the layout. It just feels wrong that it's this way.

When we have good sun, the batteries always get charged up the next day, even on cloudy days. We've been here, in the shade, for... two full days, I think.

I'm trying to determine if one or more of the following are true:

  • Is this a standard solar implementation scenario? That there is only ONE possible charger/converter to replenish the batteries installed at one time?
  • Is there a possible wiring / schematic / system design oversight or bug. (I don't have a schematic yet, I have reached out to get one, if available.)
  • There would have been an original charger/converter installed on the rig, before the Victron, etc. was installed. Does anyone ever have that still wired into the system?
  • Really, my only choices are "have sun" or "be limited to 30 amps even when 50 amp shore power is available"? This cannot be right.

I'm trying to determine that, if the Victron being on limits me to 30 amps, is there a different way to charge the batteries when on shore power? I know my question might be difficult to many without y'all knowing more about how it's wired up. But I'm hoping I kept my questions as free of the implementation as possible and focused on generalizations, and typical scenarios.

For the moment, there's a chill coming into the area tonight and I don't need two A/C's. I'm okay with the 30 amps for now, and I'll get my batteries replenished. Not a long term solution.

I truly appreciate any help anyone can put forth, or any education I can glean out of your answers. I did do extensive research into solar, DC, AC, converters/chargers, inverters, MPPT, etc. before we bought the rig. I feel sort of comfortable in my general knowledge. I was a little sad I didn't get to do the install myself so I'd REALLY know it, inside and out, but the deal was just too good to pass up and our seller was a pleasure to work with. But I lack the intimate knowledge that installing it myself would have gained.

Thanks in advance for any assistance.

So then I plugged in the charger ... guess what still says 19 amps. Being in the 5th wheel I just disconnect the - side and inserted in the shunt.

White bottom is going to the 5th wheel and Black is going to the negative side of the battery. On the battery there is nothing but the black cable.

I did connect both voltage red wires to the shunt but I haven't hooked up a second battery yet, doubt that matters

As I recall the charger was unplugged as well I never recall ever seeing a - sign for current.

Max discharge current for AGM Battery bank

Hi All

I have a 6ooAh AGM batt bank on a sailing boat (3 x 200Ah)

What is the max safe current drain for said bank, especially with longevity in mind?


I have a 1,6kW 230V AC watermaker and would like to run it off the batt bank through an inverter for about 30min at a time. (and some other power tools on the odd occasion)

I do have a generator so that watermaker can be run for longer periods but for 30min (making 50L of water), it would be very convenient to not use the generator, not to mention saving petrol, fumes, and noise.

I have 640W solar and 300W wind gen which should be more than enough to deal with the discharge, I believe, on a sunny day.

So, is there a rule of thumb for a max safe discharge current for (AGM in my case) Lead Acid Batteries?

My gut feeling is that 300A for an hour on a 600Ah bank should be safe. But then my 2nd gut will freak out when it sees 200A of discharge on the BMV.. Even 100A is a hell of a lot in my mind.
