MPPT RS 450/100 Error 35

Hi there,

Recently I saw an Error 35 for no obvious reason on my MPPT RS 450/100. Configuraiton is 9x 375Wp panels on each tracker, east-west configuration. The short circuit current of the panels is around 11,5A according to the flash-list of the manufacturer with a Imppt of around 10A.

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...

Inverter RS Ground Fault Error 42

Off Grid site installed in June 2021 has had two Error 42 Ground Fault events. One 2 months after install and one in the last 2 days. On detailed inspection with (full insulation resistance testing with a Mega tester Fluke etc) no faults could be found on array cables to earth, (and other cables that wouldnt be likely to cause issues). Has anyone else had this Error and could not locate cable faults etc? Or any other suggestions. All JA Solar panels, cables etc were brand new and have been visually checked for damage. No 4G coverage so system is not on VRM

Keen to hear thoughts.

RS 450/100 parallel arrays via one pos & neg cables

I am thinking of purchasing RS 450/100 controller which would be 60 meters away from an array of x16 - 330W Jinko panels. I already have a pos & neg 6mm2 cable in place over this distance. As the RS has two mppt trackers my proposal is to split the array into 2 x 8 panels to keep the VOC below 432V as per spec... the victron string calculator says this is fine and I could go up to 2 x 9 panels if I can find a couple more similar. Calculation Here

So, my question is to save on buying another 120 meters of cable can I Y parallel the two arrays in to the existing 6mm pos & neg cable and then just before the RS controller Y them back again to two separate arrays to feed in to the RS? Will this cause a fault or damage the controller?

Any help much appreciated

Inverter RS 48/6000 230V Smart Solar reliability and AC charging version

Doing some system planning for a global voyaging boat. The RS 48/6000 looks like a great solution because I can keep the AC system completely separate from AC shore power. In effect all AC loads will always be on inverter 100% of the time. This will eliminate voltage and frequency issues for when shore power by using separate AC battery chargers in combination with robust solar and alternators.


1- I got feedback from a Victron dealer that "HF inverters" like the RS 48/6000 are less reliable and should not be used for full time. Suggested that reliability was not as good with HF designs and they can't handle extended use. Is this really true? I understand that many "Chinese" inverters are HF designs and may contribute to the opinion but is there something inherently flawed in an HF design making it not suitable for full time use? Any reason why a more traditional larger transformer design inverter may be a better choice?

2- Understand that you are launching a Multi RS Solar 48/6000/80-400/80 charger version in January. This sounds like the perfect solution for my setup. Are specs available for this? Key question is if the 80 amp AC charger is simply that, an AC charger and the AC input is isolated (all AC loads are 100% inverter). There is no relay correct? Reason I would want this is to enable global shore power (using an autotransformer) that is frequency independent. Also, is the MPPT charger output shared with the AC charger or is it completely independent?

Hi there, my new inverter RS 48/6000 is running now with SmartShunt and Cerbo GX and a Fronius Primo 5.0. Unfortunately, I can't see the MPPT power on screen, and the MPPT doesn't appear in device list of the Cerbo. Firmware on GX is 2.57 (2.60 release candidate was running at first but the inverter doesn't appear with that version !!).

RS48 / 6000 switches off the charging process in the morning

It has happened a few times now that the charge regulator no longer charges in the morning. It is now already cold in our region in the morning and my first suspicion was that the PV modules produce an overvoltage and the SCC switches off. However, no error message is reported in the app . Sometimes I have to repeat this until it continues to charge normally for the rest of the day. What can be the reason?
I also have to say that my PV system is very slightly below the maximum permissible open circuit voltage (VOC); hence the suspicion of overvoltage on cold days. But I miss the warning for such an event.

Inverter RS 48/6000 USA 240V Power setup.


I am looking into the possibility of using an Inverter RS 48/6000 in an off-grid use-case in the US.

My thought is that I can pair the RS with an autotransformer to provide a neutral for split-phase 120v - 0v - 120v power. I have a couple of questions.

1. Can the voltage on the Inverter RS be adjusted (from 230V to 240V?)
2. Can the frequency be adjusted from 50 - 60HZ?
3. Can anyone else see any downside to this configuration (if the above two criteria are met?)

It appears from the app demo that the above power settings are possible. But I can't confirm with any spec sheet data that I could find.

Mettre neutre à la terre de l'onduleur solaire RS Smart

Bonjour à tous.

Je viens de recevoir l'onduleur RS Smart 48/6000. Étant totalement isolé du réseau et disposant d'un coffret de répartition avec 2 rangées qui débutent par des interrupteurs différentiels de 30mA, je dois réaliser une liaison du neutre à la terre.

Le manuel dit ceci : L'onduleur RS est équipé d'un relais de mise à la terre qui raccorde automatiquement la sortie du neutre au châssis. Cela permet le fonctionnement correct du commutateur de fuite à la terre et d'un disjoncteur différentiel interne connecté à la sortie.

Comment faire avec mes interrupteurs différentiels externes ? De plus, un petit câble de terre pré-dénudé se trouve dans la boîte. J'en fais quoi ?

Inverter RS 48/6000 , programmatically shutting off charger

I have a well with a solar pump. When the sun is out and the float switch is tripped in a tank, a 3kw / 240v dc pump starts using power via a controller.

Most of the time though, like 95% of the time, the 4kw / 240v dc array is being unused.

I'd like to hook an RS 48/6000 up to charge batteries and create 240v ac for a nearby cabin.

So I *think* I'd like someway to tell the victron controller "hey, stop using power when the pump wants it."

Worst case I could do some serious electrical engineering with high capacity relays and arduino but I'm hoping there's a simpler technique via built-in victron functionality.

I know the RS is a high frequency design that may not start motors as well as the LF designs, but it has other benefits I would like to have. Any thoughts would be appreciated.

Victron 12V / 2000 Multipass Compact - Red Alarm flashing, turns off

Description of failure:

I have a Victron Multipass 12V / 2000. I am using a induction range that pulls between 60~85amps. It has tripped the inverter and the red flashing (slow flash) alarm light is on all the time. Eventually the inverter shuts down all together. When reset, it will work again for a period of about 5 minutes once reset (power cycle down). With shore power no issue. WIth engine on same situation where it lasts about 5 minutes then when using induction range it will trip the inverter again red flashing light. WIth engine on eventually all comes back on operable, but then after use same situation - trips off.

Took the unit into a auto repair shop. They stated that the alarm parameters are "too tight" and the unit is shutting down as a result.

Rs 48/6000 really 2 indpendent MppT ?

In this video from Victron on YouTube ( ) in minute 3:26 the guy says that the RS48/6000 has 2 independent MppT tracker for two independent PV-strings.

In this Manual i found ( ) under 2.2 it say that ....."Two strings can be connected to the inputs. Both are wired parallel to one tracker, therefore the two strings must be equal in number of solar panels and type. The total allowed input current is limited by the device to 18A .

What's right now? Does he have two independent Mppts ?

When the PV String internaly connectet in parallel there can`t be two trackers , right ?

Please help me for the correct information because I am about to buy the RS48 / 6000 and this information is important to me.
