Smartshunt firmware 2.33 failed to install.

A new beta came out today that includes smartshunt 2.33. It failed during the upgrade. I now cannot connect. I get the message to install the firmware. Tried the officially released version and it fails also. the smartshunt is connected to my color control and appears to be reporting fine. I just can’t connect to it via Bluetooth without getting the message to upgrade the firmware.

Solar controller 100/30 not fully charging vmax slr155AGM

I have the controller set at the default 2 position on the dial. The first time I set it up, it got up to 14.4v and went to absorption, then to float. My battery was fully charged. The last two days (everything is new) my battery seems to get “stuck” at around 12.7 volts. I have 200 watts of solar. My battery is back up to 12.6 by noon, but it’s never getting higher Despite it being sunny. All afternoon I see anywhere from 70- 100 watts and 5-6 amps from my panels, but my battery voltage is refusing to rise.

FWIW, the battery and charger are in the same space and are the same temperature. Connections look tight. Things worked on my first charging run also, but not now. It was also in full Sun and got that day too. I’m stumped. Any ideas?

Big difference between from and to battery

If I look to my statistics in VRM on 30 days there is a big difference between how many power that comes from or go’s to the battery. In my opinion this difference can only be as large as my battery size.

if you look at the from solar and direct use there are the same

SmartSolar Charge Controller MPPT 150/35 MPPT Error #28 Power stage issue Q2

Reference my previous question...

SmartSolar Charge Controller MPPT 150/35 MPPT Error #28 Power stage issue - Victron Community (

So I've sent my unit in for warranty, and the repair station is telling me I've overloaded it and caused the damage - Warranty Denied.

I suspect the unit was faulty from original manufacture, because I was never able to produce the power expected. Originally I had 8 solar panels and could only produce about 500 Watts. Here’s a typical screen shot under full sun…


Since I was never producing more than about 500 watts with my bank of 8 panels, I decided to go up to 16 panels. The spec sheet says that if more power is connected, the controller will limit input power. I made sure I didn’t exceed the 150V and 40 amp input maximums. VOC is only 109.6V with 4 panels in series, and ISC is only 35.92 with 4 panels in parallel. Shouldn’t the MPPT be able to handle this setup?

Looking for Smartshunt configuration advice

Hello everyone, I’m looking for some guidance on how best to configure my smartshunt. It has been physically installed correctly will all sources funnelling through it prior to the battery bank that is made up of two Lithium’s for a total of 540ah.

The problem I’m having is; the batteries are current at 85%, I know this through the BMS however the shunt is reporting 100%. Here are my settings, sure wish there was a way to post a screenshot

Battery capacity: 540 ah

Charge voltage: 13.4

Discharge floor: 10%
Tail current: 4%
Charged detection time: 3m

Peukert component: 1.05

Charge efficiency factor: 99%
Current threshold: 0.10 a

Time-to-go average period: 3m

Battery start synchronized is on

I’ll wait until the charger goes to float and the batteries are known to be 100% then I’ll manually synchronize. I’d hate to have to do this every time though.

Appreciate any assistance.

what is the required increasd of batteries voltage to activat the Error :#38 ?

Hi All

Our system consisted of 9 Quattro 15 Kva inverters, and 23 SmartSolar MPPT 250/100,

System working four months without problems, 6 days ago the Error Code: #38 appeared in our solar system and one of the MPPT Solar Charger burned and all remaining solar chargers stop working (no charge from the solar, no light flashing ) when we try to investigate about this we found 2.4V variation between the MPPT solar chargers, and inverters charge voltage setting. (MPPT setting : absorption =55.2V float=54V, equalization not active (disable))and inverter setting is ( absorption =57.6V,float=55.2V, equalization not active (disable )), So our concern is if this variation (2.4)V could cause error #38? , if this error could burn and make all solar mppt faulty.? If yes why has the system working for about 4 months with this configuration without any problems?

Are Assistant Programmable Relay 'Switch conditions' evaluated as AND or OR?

I want to make sure I've configured my MultiPlus' correctly. So far when I've used more than one 'Switch condition' all conditions were natually met so I still don't know if selecting multiple conditions are 'AND' values (all must be met), and not 'OR' (any combination).

I was able to verify the 'Extra drive options' are OR values by selecting 'in case of general system failure' and the assistant worked despite being selected. I've created quite a few programable relays to ensure they're evaluated as 'OR' values.

I suppose I can add another programmable relay with mutually exclusive switch conditions. I'd rather know from the source how they are supposed to behave rather than assume and potentially get tripped up on a new firmware release.

MultiPlus reported amps under reported when generator running.

I'm running two MulitPlus 24/3000/70-50 120V in parallel. firmware v482.
When the multis inverting the AC-OUT Watts is close enough (+- a few percent) to V*A = W.
With Honda EU2200i generator running:
AC IN: rough average V*(A*1.6) = W
AC OUT: rough average V*(A*2.56) = W

Input limit: 5.0A
Overruled by remote:

Inverter Power Assist: Off

With generator running
AC IN 1:
Voltage: 120
Current: 9.5 (15.2\9.5=1.6)
Power: 1826W
Frequency: 60.3Hz

Voltage: 120
Current: 3.8A (9.725\3.8)=2.56)
Power: 1167W
Frequency: 59.9Hz

Voltage: 26.69V
Current: 22A

As long as I set the Input limit to 1/3 of what I want the maximum watts pulled from the generator, it won't overload the generator. Setting it at 4.3A in general ensures it never pulls much more than 1,800W. At 5W it will creap up towards 1,900W and bounce between there and 2,100W at 120V.

I did measure same length 5' (1.5M) and torque down the 6 AWG(13.3mm2) THHN copper from busbar to the two Multi's the same. However, amp meter shows load is different about 1:3 between the two Multi's. Wondering if that mismatch in load is the cause of my issues? Unsure what to do other than maybe change out the THHN wire to Ancor Marine 266 strand tin coated copper.

Just so strange that the AC OUT L1 current is so far off when in passthru vs. inverting.

Thanks in advance for any ideas.

SmartSolar Charge Controller MPPT 150/35 MPPT Error #28 Power stage issue

My charge controller is displaying an error code # 28 and is interrupting charging. The recommended solution is to "Disconnect all wires, and then reconnect all wires. If the error persists the charge controller is probably faulty." I've tried disconnecting the wires, and on restart, the controller seems to produce good power for a few seconds, then quickly drops to about 15% current. The controller will continue to charge, sometimes for many hours, at 15% current.

I have a 4P4S Solar Panel configuration charging a 48V bank of LifePo4 cells.

Panels are each Pm 200W, Voc 27.4V, Isc 8.98A

Is this controller damaged, or can it be rectified with software updates? Should I send this in for further warranty investigation?

Bad performance af Bluesolar MPPT 75/10 with 40W of panels

I am struggling to find the cause of very bad performance of my sailboat 40W solar panel installation.

The controller is Bluesolar MPPT 75/10. There are 2 horizontal panels of 20W each, connected in parallel. The panels are Sunbeam Tough Flush T20F. According to data they are supposed to have Vmp=20.88V, Imp=0.99A, Voc=24.48V and Isc=1.19A each.

My gel battery is not full and needs charge. The last weeks there has been plenty of sun. I am in south of Sweden. However the max power seems to be only mediocre 4W and a typical daily yield is only 30-50 Wh. The panel current sum normally is 0.3A in full sun when the panels are not shaded.

The cable is 2.5 mm2 from the panels. I have checked all connections. I even tested another temporary cable just to be sure.

According to nearby weather stations solar radiation intensity is typically 960 W/m2 at this time of the year, which is not that far away from the test conditions 1000 W/m2.

According to the Victron calculator the panels should produce almost 150 Wh/day or a max charge current of around 3A. But my poor 30 Wh/day or max current 0.3A is simply so much lower that I am now frustrated. I was hoping for at least 100 Wh/d or perhaps even more. A max power of 25W or current of 2A was also in my expectations from this 40W installation.

With a Fluke 179 multimeter I have measured the sum from the two parallelled horizontal panels as Voc=21.9V and Isc=0.95A when in max sun at 13:00. That is much lower than the panel data, isn't it? As there are two panels Isc should be 2*1.19A=2.4A at perfect conditions.

My tests also reveal that one of the panels seems weak, as it only gives half the current than the other does. And its voltage seems lower than the other.

The solar panel producer Sunbeam says that the Victron controller is not good enough and wants me to buy theirs instead. They say that their controller starts at a much lower voltage difference and consumes much less power, They say it is better than the Victron, in what ways I don't know.

I have read various posts here on the subject, but it seems as everyone is getting much more out of their panels than I do.

Should I claim warranty on one or both of the panels?
Or am I simply expecting too much?
Or could there be a problem with the Victron Bluesolar MPPT 75/10 controller itself?

How to keep load on during the day and switch off at night time - MPPT


I would like to have my MPPT 75/15 to operate as normal during the day, but cut power to the load at night.

I like the concept of the street light function however it appears to only do the opposite.

I have searched other options on the forum which have pointed towards the user defined algorithms in the load output operation mode section.

I read that it has 'load switch high voltage level' and 'load switch low voltage level.' I want the load to completely turn off, not just reduce in power. Maybe it does cut off power completely and I am just interpreting it incorrectly.

If you could please let me achieve my scenario that would be great.

Is there any alternative BMS out there I could use that would be similar to the VE.Bus BMS? I don't have room or the option to use the new Lynx Smart BMS, so that is off the table.

MPPT 150|100 battery voltage reading high

I have recently upgraded our existing off-grid installation to include the following:

1.5kW existing panels -> MPPT 100|20 48v -> 48v 400Ah battery bank

4.5kW new Jinko panels -> MPPT 150|100 -> same 48v 400Ah battery bank

Cabling is short and the voltage drop between the controllers and the battery bank is less than 0.01V. The two charge controllers are networked over bluetooth and each has the most recent firmware. However synchronizing the two controllers is a problem because the MPPT 150|100 is incorrectly reading a battery voltage 0.2V high, and hence moving from Bulk->Absorbtion->Float earlier than the smaller controller.

For example, the 100|20 status display may report a battery voltage of (say) 55.7V. This voltage can be confirmed via actual measurement at the 100|20 terminals, the 150|100 terminals, and also at the battery bank itself. However the 150|100 at this time instead reports 55.9V. As a result, the 100|150 switches up between charge modes prematurely (and presumably switches down late as the battery voltage falls), switching the larger panel array into Absorbtion while the small array continues to operate in Bulk. Accordingly, the larger solar array is effectively switched out before the batteries are fully charged leaving the small array to finish the task. Although this is unlikely to cause a problem in sunny days, the premature switching out of the larger array on overcast days does not permit full recharge of the batteries and to an extent defeats the intent of this upgrade. As a temporary workaround, I have set the 150|100 Absorbtion and Float voltages 0.2v high to compensate for the battery reading error which does seem to help, but I am unsure as to whether this may eventually contribute to cooking the batteries and do not see this as a permanent fix for this new device.

Has anyone else encountered this problem? Can the problematic 150|100 be recalibrated in the field? - or is this a matter that can only be fixed with a replacement controller?

Cheers, Richard

Multiplus II - DC current is wrong.

I have a Multiplus II 48v 5KVA. When running but with the output isolated, Venus reports 53.53v and -0.7a, giving 37.47W standby power.

Clearly greater than the specified 21w standby power.

The reported current is incorrect, a clip on meter gives 397mA which would give the correct 21W standby power. It is disappointing to find such a large discrepancy on a quality product.

This causes problems with negative DC currents which have been discussed on numerous posts.

Is there any way to zero the current meter in this unit ?

Turned it off and on and after a couple of mins did the same thing. No flashing of error code, just straight to alarm on. Tried charging through shoreline connection and that worked fine. Put it to on after an hour of charging and within 20 mins it cuts out again. The manual states error codes for a flashing alarm led, but mine just goes straight to solid on. The voltage at the dc input terminals was 12.6v and I removed both ac input and output connections and it still cuts out. Any help would be greatly appreciated.

MultiPlus: Disable Charger based on battery temperature

I'm currently building an RV off-grid system based around a Lithium Tesla Battery and MultiPlus. In the system is also a BMV 702, BatteryProtect 220 and Color Control.

As the Lithium Battery really doesn't like to be charged below freezing temperature I'm planning to have an automated heating pad that keeps the battery warm, but I would like to have a fail safe which disables the MultiPlus Charger whenever the temperature of the Battery reaches 5°C

My current setup is to connect the BMV-702 Temperature Control Sensor to the Battery and then connected the BMV-702 Relay to the MultiPlus AUX1 which controls the Charger via the Charge Assistant. This works nicely, but I was wondering:

1. The MultiPlus already has a Temperature Sense Connector plus the Temperature Sensor shipped, when I measure the voltage of the Temperature sensor I get a reading of 2.6V at 25°C. Is there any datasheet of the Temperature Sensor that I could use to configure the MultiPlus Assistant for temperature? I would really like to not depend on the BMV for the temperature measuring and best have the MultiPlus measure the temperature directly.

2. I found the new Shared Temperature Sense feature of the Venus/ColorControl: which mentions:

the Venus-device will send the battery temperature to the connected Solar Chargers and Inverter/chargers.

But I don't see anything in the MultiPlus Configuration Screen to do anything with that Temperature or any other way that it actually receives the temperature form the Venus/ColorControl.

Plus just two other small questions:

1. Is there any way to see the current voltage reading on the MultiPlus AUX inputs? I'm having a bit a hard time to find the correct voltages to use in the Assistant

2. When I disable the Charger in the VEConfig all together, but then enable the Charger again via the Assistant based on the AUX1. The charger is actually running! That's a bit scary ;) Also which charge settings are used? I assume just the last settings of the charger before it was disabled all together?

"Input Current Limit" on VRM Dashboard

I noticed something odd on the VRM Dashboard and wonder if it is bit of a temporary display glitch or is a setting somewhere?

Dashboard when I have my AC Source defined as Grid. (Generator shows the same.


If I change the source designation to "Shore" I see the same screen in the main - but I get a new section (I highlighted in a red box) called "Input Current Limit"


Not sure why that appears only when AC In is "Shore"? or why it is 3.2A. The Watts in is actually around the 3.2A mark (230V input) but that is more coincidence I think.

The only setting I can think of that limits the AC current is within the Multiplus (an EasyPlus 12/1600 in my case) and that is set as 12.0A (see below - set at 12A as using a domestic plug).


Any pointers to this odd 3.2A window? Would be a pain if that was actually 3.2A and stop me using anything of reasonably high power!

EDIT: Just turned on the Water Boiler (850W) and checked screen again ...


It looks like the "Input Current Limit" actually shows the approximate AC current being pulled into the system, not an actual limit? and is fluctating as the battery charge current is dropping as approaching full.

So it is good that it is not limiting the current, but what is it meant to mean?
