Firmware Update & Battery Charging

Hi, I am new to solar systems (pretty excited) and have just purchased an Easy Solar 24/1600/40/16 MPPT 100/50, BMV712, VE Bluetooth dongle (for controller) and two 12v 220 amp Lead Acid Batteries which I will be taking to my remote cabin. There is no internet or mains power available there.

I have two questions which I would appreciate answers for.

Is it ok to charge my batteries using the easy solar, charge only mode, connected to mains before i take them bush and connect the solar panels? How will I know the batteries are 100% charged before syncing to the BMV?

Regarding the BMV712. Should I update the firmware (is it necessary) on the BMV before syncing to the batteries? Are there other devices needing firmware updates in the Easy Solar and if so should I update those as well before taking them out of internet access?

Thanks for help in advance.

Can MultiPlus Compact 12/1600/70 firmware be updated through VE.Connect?

Hello everyone. I have a MultiPlus Compact 12/1600/70-16 on firmware version 154. Is this firmware out-of-date? Can this Multi's firmware be updated using VE.Connect, or do I need to use the (deprecated, dangerous(??)) VEFlash method?

Reason for wanting to update:

In addition to the Multi, the system has a BMV-702, CCGX, and 2x MPPT 100/50. The MPPTs charge a 12 volt ReLion lithium-ion battery bank from two separate solar PV arrays.

I would like to tell the MPPTs that the battery voltage is what the BMV-702 measures, and not what each MPPT senses at its "battery" output terminals.

This is because in bulk charging there is a discrepancy of as much as 0.7 V between MPPT and battery voltages, depending on charging current. Under float conditions, the discrepancy tends slowly towards 0.1 V. The voltage drop from the MPPT output terminals to the battery's terminals is presumably due to the cabling, fuses, and isolator switches, none of which can be changed.

I want the MPPT to receive battery voltage data from the BMV-702 (or maybe the Multi) to solve this problem.

I read here that I can do this with the CCGX using DVCC and SVS. However, when I tried this I got an error message saying that there is a firmware incompatibility issue. Since all firmware in the CCGX, the BMV, and MPPTs is up-to-date I conclude it must be an issue with the Multiplus' firmware.

Any help greatly appreciated!

Nach Update auf V1.50; Warum lädt der MPPT 75/15 Laderegler nur noch in Erhaltungsspannung (Bulk) ?

Hallo, wir haben einen Smart Solar MPPT 75/15 an einem 110 Watt Solar Panel und einer 225 Amp/h Batterie installiert.

Vor dem Software Update auf V.1.50 hat das System toll funktioniert.

Bulk und Float alles ok. Siehe bitte Foto.

Nach dem Update auf V1.50 kennt das System nur noch Bulk - Ladung.

In den Tagen vor und nach dem Software Update waren keine Stromverbraucher aktiv. Auch sonst wurde nichts am System verändert.

Wir haben nun seit 3 Tagen Verbraucher hinzugeschaltet. Das System lädt weiterhin nur in Erhaltungsladung - Bulk weiter. Die Sonneneinstrahlung ist in den Tagen vergleichbar.

Warum lädt der MPPT 75/15 nur noch in Erhaltungsspannung (Bulk) ?

Gibt es ein neues Softwareupdate? Oder kann man auf die alte Software Version zurück wechseln?

Vielen Dank schon einmal im voraus für die Informationen.

MPPT 75/15 load output inrush current issue after 1.50 firmware update

Hi, after updating to the latest firmware today (I believe it is 1.5 / 5.24) on my MPPT 75/15, the load output is turning off when I switch on some of my DC devices.

I suspect it is switching off due to DC inrush current as the load output comes back on after a couple of seconds.

It has been working fine up until the latest f/w was applied, so I suspect there has been a change / bug introduced.

One device that is causing the load to drop is a LED security light - not ideal as the load will disconnect every time it is triggered.

Is there anyway of reverting to the previous firmware version until this is fixed?

Quattro 12 / 5000 / 120-2 x100 120v Firmware Update needed

I am adding a VE bus Smart Dongle to my Victron Quattro 12 / 5000 / 120-2 x100 120v and received a message in the connect app that the current firmware version is v413 and is not compatible with VictronConnect. It stated I needed to upgrade my firmware to 415 or higher.

I installed the system myself and bought it from a Victron Authorized Dealer who is telling me they cannot help with firmware and was unable to point me to a source where I can obtain a copy of the firmware update. The serial number of my unit is 2733413.VFD

If it matters I am running a 12v system with 8 Battle Born Lithium Batteries in a Class A Motorhome.


Can someone post the correct firmware update I need?

BlueSolar MPPT 75/15 - PV power jumping up and down to zero in bulk

Dear Victron fans,

After the last update of the firmware to 1.50 and with factory values, I noticed a strange bulk behavior: The curves are rising and falling (jumping) in seconds, sometimes down to zero (see screenshots). As a result, it took a long time to charge the battery. Oddly enough, the charging process seems to be normal when the engine is running and the battery is being charged (at the same time).

  • does anyone know the phenomenon?
  • maybe it has something to do with the upate?
  • maybe this is normal?



  • the engine is off


  • the engine is running

75/15 Smart Solar not charging since firmware update

Last week I logged into my charger and had to apply a couple of firmware updates. Now the bluetooth connection is unstable and is no longer charging. I see a voltage in the 50's (3x100 watt panels in series) but zero watts or amps. I can connect fine with BMV-712 and battery sense. I reset to factory defaults, but still not working. Any suggestions?

VEFlash needs firmware file - where to get it?

Hi gents, I have Multiplus type 26, still with old firmware 2609158.

I would like to upgrade (Lithium ready). VictronConnect on Win7 says I need to use VEFlash and that one asks to download firmware first.

I can connect with my Android tablet to the MPPT using bluetooth dongle, but the MultiPlus doesn't have to port/option I guess.

So I need the firmware file. How do I get it? I spent 10 years in networking, CCNP CCIP - no newbee

hard (without app) factory reset MPPT 75/15 smart solor charger


I purchaged a MPPT 75/15 smartsolar charger (replacement of a 14 years old PWS charger) for a original 50 Watts panel (also 14 years ago), just to boost a bit of the efficiency compensating for the panels age and charger technology.

Hardware version V01.

Many connectivity issues using bluetooth from Android 10 and MacOS (seemed impossible to get connected from the android 10 device - followed all instructions related to the bluetooth specifics as per victron).

Finally using MacOS I managed to get connected. And once I have got a charging display with voltage and power (values as expected). Second time I started the app on the Mac, it forced me to update the firmware, no way around. I hit the update button and from then onwards all misery (note less than one meter away from the charger all the time).

Somehow the update failed and now it gives me firmware version: none -> please update to 1.46

Green and yellow led flashing rapidly.

There is no longer any way to connect (unpowered for 30 min as well, multiple times).

Also error D26 comes in the app (MacOs):

Updating failed, communication lost. The product might be unusable. Check connection and power supply.
Try again and check the product settings once updated.

Again, all bluetooth reset / reconnect as per Victron have been followed.

So obviously the firmware is corrupt and I'm now looking for a *hardware* reset option which I asume would load the original firmware and resets all.

Any software / app option is not what I'm looking for.

Where is it?

Thx, Jan Jaap

Do I have to install ESS into each Multi? (I have 2 in parallel)

In "Changelog assistants" file I see, that ESS now suppports limitting FeedIn power:

Release date: January 24, 2020

Supports limiting the FeedIn power. (Starting from firmware revision 469)

I updated my MultiPlus 48/5000/70-100 to 2624469 firmware version, but I cannot find in ESS menu on CCGX panel the line, in which I could limit the FeedIn Power.

Maybe it does not work because I have 2 Multiplus devices in parallel?

What I have also found out, that though I disabled FeedIn, it still feeds energy in, taking it not only from my Solar panels, but also from my batteries. Isn't it strange?

Multiplus compact Firmware Update Problem - failed at 9%

The Firmware update on my Multiplus compact 12/1600/70 via VEFlash and MK3 USB Interface from Version 1906132 to 1906159 started fine. Following the described procedure I could connect and start the update without problems.

The "Busy Programming Firmware" window appeared and the counter run from 1% to 9%, when the update stopped suddenly. Now the Multiplus doesn't do anything except flashing the green charger LED fast.

I can't connect again or do anything else with the unit, so I hope for a suggestion for a solution here.

SmartSolar 250/60 mppt controller shows Unknown Product (A068) on Victron app

We have two existing 250/60 mppt controllers (PID:0xA05D & FW:139) which connect fine via Bluetooth and VE.Direct. Our brand new 250/60 mppt controller (PID:0xA068 & FW:147) works, but we can't connect via the latest Victron app to change settings or see history. Both Bluetooth and VE.Direct methods say "Unknown Product (A068)" when we try to connect. The only way we can get data from the new controller is via VE.Direct rs232 comms.

Why are the new controller PID and FW versions so different from our existing up-to-date controllers?

My understanding is it does not have a VE.Bus, however it can still be configured using the original VEConfigure, (but is not compatible to VEConfigure 2 or 3, and the firmware cannot be updated). Is this right?
Do I need a MK2 to USB and RJ45 cable to use VEConfigure with this unit?
Does VEConfigure allow me to change any settings which I otherwise can't change using the dip switches?

I want to use the charger for a LiFePO4 bank, can someone tell me what settings I can change using VEConfigure 1? Will I have enough control to adapt this charger for a LiFePO4 bank?

Victron smart dongle firmware and setup

I have a Victron system with multiplus compact 12/1200, mppt smart solar, smart dongle, bmw 712 and color gx. Everything is connected in a bluetooth network and mppt and bmw 712 with to color gx. I have not installed temp sensor for multiplus, but connected smart dongle to multiplus with rj45 plug. Multiplus is connected to color gx with rj45 plug. As far as I can find out this is correct. All victron devices are updated with the latest software including multiplus (460) with the exception of smart dongle which has firmware v1.07. When i try to update smart dongle via victron connect i do not get access to update files..?

So my first question is what is the latest smart dongle firmware?

The other question is that smart dongle runs in "secondary mode" because color gx is connected. Is this wrong when I do not have temp sensor on mbw 712 or multiplus?

My idea was that smart dongle should share battery temp to all devices in the network, is this not possible?

BYD 13.8 Firmware Update

Could someone please explain the procedure of updating the firmware of BYD 13.8?

I installed a three phase system of 15KVA Quattro on a parallel system of 5 units 13.8kWH. BYD firmware version: 4.22

Observations: I have a Charge Current Limit (CCL) of 875A

The total charging power displayed on the CCGX is the cumulative of the inverters charging power. (Which is very fine)

Now I installed the same 3 phase system using 4 BYDs but the firmware version is 4.17

Observation: The charging power displayed on the CCGX is the power of a single inverter i.e the charging power of the inverter the CCGX was connected to(Master/L1)

The Charge Current Limit (CCL) displayed on the parameter is also 175A.

This is traceable to the firmware version of the BYD. Any assistance to be rendered to update this BMU will be appreciated. No traceable solution on the internet.
