Adding Solar to Sprinter RV
The coach (WB Navion) is equipped with: (2 * 100) Zamp panels on a 30A PWM Controller, (2 * 125 Ah,) Lithium Batteries. and a Zantrex 2KW Inverter/Charger.

So here's my plan:
1) Connect the (2 *100) Zamp panels in Series and feed them to a Victron MPPT 100/20 Controller.
2) Add (2 * 210) Newpowa panels (Voc=39.6V, Imp=6.24A) and feed them to a Victron MPPT 100/50 Controller.

Did not want to mix panels, so opted for separate Controllers.... Please ignore the "extra" stuff: Lynx Distributor, Smart-Shunt, Cerbo GX, and GX Display/Touch).

Question: Is 620W of Solar overkill for this system?

Quatro 3000 firmware failure

Hi, I have a quatro 12 3000 120 a firmware upgrade failed. Now all 8 leds turn on and i cannot connect to the unit. I have tried the android app with the firmware fail option without success. The app can not find the inverter. I am using a mk3 interface. If I depower the unit and wait, when I repower the unit , it takes about 8 seconds for all the leds to turn on.

I have tried with 12v and 240v connected to it.

Any ideas ?

No BMV 712 history, inverter shows low voltage protection

Hi all, I've asked a similar question before, but after doing some trouble shooting, I still have an issue I'm trying to solve for. I'm converting a Ford Transit 250 into a camper and just finished setting up my electric system last week.


BMV 712 Smart Battery Monitor

MPPT 100v 30A Solar Charge Controller

(3) 100Ah LiFePO4 Battle Born batteries

Giandel 2200W Pure Sine Wave Inverter

Sterling 60A B2B Charger

Progressive Dynamics 60A 12v LiFEPO4 Battery Converter/Charger

What I’m trying to solve for is that when I turn my inverter on, it beeps continuously and says "Lo", indicating low voltage protection, and then shuts off.

I have taken apart the inverter and checked that the fuses are in good shape. (There are 4 30A fuses and they are all good).

I have charged up my battery bank to full, using my PD Converter, and synchronized the SOC to 100% on my BMV 712, as well as input the correct battery monitor settings in the Victron app.

It was previously recommended to me that maybe my main 300A fuse was blown, or that there was a short somewhere. I have used a multimeter to test all connections and I’m getting consistent voltage of over 13v anywhere I test. That leads me to believe that there is not a short, and that the 300A fuse is not blown (I've tested on both sides of the fuse).

However, my BMV 712 will not show any history (please see my updated attachments).

What am I missing here? Does anyone have any suggestions?

MPPT & Multiplus Dual Charging & avoiding overcharge


Could only find a single post on this topic. So I have a Multiplus 12/3000/120 and a MPPT 100/50 newly installed in my travel trailer.

What is the best way to go about configuring the chargers that avoids overcharging the batteries when both solar is available and shore power on the Multiplus? I am fearful of overcharging the batteries when both units have available power for charging.

Only thread I found mentioned disabling one of the chargers. I find this to be a poor solution as I do NOT want to have to manually monitor the chargers and remember when to turn them on or off. I would expect Victrons products to be intelligent enough to not overcharge when both sources are available but that's more hope than reality at this point. Please help! Thanks!!

100/20 48v charger in pv input

Can I connect a 48v charger that has 58.8v 8a specifications to the PV input on the MPPT 100/20 48v to charge a 48v LifePO4 battery? I'm not sure the charger is 3 stage so I don't want to connect it directly to the battery as it might damage it. But if it is connected through the MPPT I believe the MPPT will only suppy whatever charge is needed to the battery.

Lithium - Repeated Absorption

Hi All

Is it bad for Lithium batteries to be going in to bulk / absorption daily - when they probably don't need to ?

Situation is....

  • yacht in marina
  • connected shore power
  • the Multiplus has the batteries in float
  • small 12v loads are being covered by the Multiplus
  • Sun rises everyday - and the MPPTs go to Bulk, then Absorption
  • The multi reduces the Amps as the MPPTs start to provide
  • the result in the batteries are full
  • and the MPPTs are going in to Bulk, then Absorption, every day

Parallel solar array wiring configuration

I am trying to figure out the best way to wire my solar array. I will be running:

6 x 370W Trina solar panels with my Smart Solar MPPT 150/100 TR (Batteries are 24v). Photo attached of PV panel specs

Each panel has a max short circuit current rating of 11.37A. So I was thinking of running a 15A MC4 fuse for each panel. But the part I'm not sure about it how many cables I should run.

For example, Should I run smaller cables from each individual panel down to my electrical box, so I would have 12 cables (6 pos and 6 neg) running down to my electrical cabinet. (This seems like alot of cables...)


Should I join the panels into 3 pairs of 2 with MC4 splitters, so I would have 6 larger cables (3 pos and 3 neg) running down to my electrical cabinet


Another configuration?

The cable run from the furthest panel from the electrical cabinet is just under 10m. So obviously whichever way I go I need the cable to be large enough to carry the current (in this case at least 15A for one panel, due to fuse size) over that distance for however many panels are feeding it but also small enough to be soldered into an MC4 connector.

I know that in some cases people use like a junction box to join the panels, but I really don't like the idea of a box being on the roof in the weather to get moisture etc inside of it. I'd prefer them to all join in the electrical box which I am planning on doing.

Sorry for the long question. Just trying to find out the proper way to do things. If that's completely different from what I'm imagining, I'm willing to embrace it.

50A charge only with my Victron MultiPlus 12/1600 / 70-16

My Victron MultiPlus 12/1600 / 70-16 does not charge with more than 50A ... it should be able to charge with 70A according to spec. Have you experienced anything similar? Do you have an explanation for what limits the charge?

The battery is not the limit, I can charge with significantly higher power with the generator. Attach my settings. The charge is about 60A in the beginning, the solar panel is alive. 10A and Multin 50A ....

MPPT RS 450/100 Error 35

Hi there,

The error did happen when there was sun / clouds in short alternation leading to sharp bumps in solar production. Voltage was around 350V according to the logged data, my battery voltage is between 46V and 52.4V (pylontech battery).

Any clues what might be happening here? The unit is two month old...

Easy Solar & Cerbo


I just recently installed Easy Solar with Cerbo and GX Touch along with an AGM supercycle battery into a Mercedes Vario bus converted to a camper. Everything looks ok but I can't get the battery % to appear on the GX Touch so I have no idea of battery state. I connected to SP and fully charged the battery which I thought would then feed the info to the Cerbo through the battery controller in the Easy Solar but that hasn't happened. I have a lead coming from the vehicle battery to the AGM to charge it when driving.

What I am wondering, is there a way to get this working or do I need to install a smart shunt? If I do need to install a smart shunt will this connect to the cerbo via bluetooth or do I need connect with a VE connect cable?

It would be disappointing if I need a battery monitor on top of the Easy Solar.....

Looking for input - 4 to 20mA and 0 to 10V senders

Hello Community!

We’re considering to add a USB accessory to our GX product range, to add 0 to 10V, as well 4 to 20mA inputs.

But since all of us have very limited experience with 4 to 20mA tank senders, we're looking for some input:

  1. Is it always 4mA = tank empty, and 20mA is tank is full? Or do the empty and full levels need to be configurable in a software setting on the GX Device?
  2. And how important is it that the transducer can be powered by our device?
  3. Anything else we should keep in mind when designing a 4 to 20mA input? Good features you have seen else where?

Also, if you are using 4 to 20 mA senders, please post a link to a datasheet or specs below. And if you have an opinion on the sender, what you like/don't like, welcome to add that.

Lastly, most questions above are for 4 to 20mA, not for 0 to 10V - but if you have special comments about 0 to 10V, welcome as well - obviously. The product we have in mind will have inputs that can be used for both types.

Note, that this is quite early in the product development, I can’t say anything for now with regards to availability dates.

All the best and thank you! Matthijs

ps. just to prevent any question about this: we'll soon launch a new Venus OS version that can work with irregular tank shapes, as well as naming tanks and some more features: all those features will also available for the 0 to 10V and 4 to 20mA inputs. Details here.

What does a Multiplus 12 800 do when a generator is present.

I am interested in the functionality which I havent quite understood.

I have a Honda EU 20 with 1800W max and a Multiplus 800.

On battery I can supply up to 800W ish with known limitations (temp and cos phi)

Now can I get the full generator power of 1800W via its transfer switch through the 800 unit?

Does it boost the 1800 W to plus 800W to 2.6 kW short term?

Is it shore power limit to limit to 1800W and then taking as much or as little as it can get to charge the batteries.

Is being shut off due to overload a problematic state of operation. You cant beat stupid and I m hoping it will just stop working if somebody tries his hair dryer and that is an obvious enough sign for the ignorant user.

Boat setup: 12v house bank, 48v electric propulsion bank, solar array

Hi, I am about to buy a used sailing trimaran and can't quite wrap my head around the ideal electrical setup. Any help would be much appreciated.

  • The boat has an existing 12v house bank (100ah lifepo4) which is sufficient at sea
  • All wiring and electrical appliances are 12v optimised
  • A 12v to 220v 2000W inverter is installed for power-hungry appliances
  • I've got 6 x 100W semi-flexible solar panels and plan to use 3x Victron 100 / 20 MPPT charge controllers
  • This should enable to keep the battery topped most of the time, with little electrity use at night

Additionally I'm planning to add the following:

  • 48v electric engine as secondary propulsion (sails 95% of the time)
  • 6.0KW max draw, 1.0KW max hydro regeneration
  • 8.9 KW lifepo4 dedicated propulsion battery from manufacturer

I would like to intelligently combine the two systems/batteries as I expect that usually one or the other has more energy than it needs. So a bidirectional 12v - 48v charge system / battery combiner is what I am looking to implement.

I'm aware of cyrix products but not quite sure how to implement them in a 12v / 48v system.

Thanks for reading, curious about your ideas and solutions.

Orion Smart: How to controll the "engine on" function for multiple outboards??

Hi community,

I have a boat with 2 outboards connected to a AGM starter bank. From here I would like to charge my lithium bank using 2 x Orion TR smart 12/12-30.

I have read about the voltage settings for starting and stopping. All good so far.

The problem starts if I run only one of the outboards (trolling etc) both Orions will start and overload the one 50ah alternator.

Is there a signal from each outboard I can connect to the Orions on/off port? What type of signal is accepted? On / off voltage or just short cutting? Do not know what the Yamahas provide.

I also have the Cerbo Gx connected to the NMEA 2000 so maybe the relays can be used if the cerbo understands which outboard is on/off?

For info I have the following equipment;

- 2 x 100ah lithium batteries c/w bms (aio)

- 2 x Orion Smart 12/12-30

- Cerbo GX

- Smart Shunt

- Smart MPPT 100/30 + solar panels

- 2 x yamaha f225

Hope there is someone out there with the same setup that can share their setup.
