EasySolar 48/5000 + ACinput + DC coupling


I have some issue charging my hybrid installation with public grid.

Description :

- EasySolar 48/5000 with CCGX

- Solar field

- 500 Ah battery capacity

PV has been prioritized in order to be fully used. To do so, virtual switch has been configured as follows.





ACinput is hardly activated, though battery voltage has reached the set treshhold.

After analysing VRM datas, ACinput relay switches ON and immediately switches off.

Grid parameters, VE.Bus State and virtual switch seem to all have an impact on that activation


Has anyone dealed with the same kind of dysfunctioning?

How can i solve it?

Recommended type of RCCB for Victron Quattro 8000 running with ESS

I am located in Portugal and using a set of 2 Quattros 8000 with ESS assistant.

For the AC1 out of the Quattro it is recommended to use a RCCB.

I am using two Hager CFC240P 300mA, type AC. However they tripp quite often.

What is the advisable type of RCCB to be used in Europe for this type of installation?

AC, A, F, B ?

Multiplus 5k ignores input current limit with power assist

I have a Multiplus 24/5000 that I am using to run the dive compressor on my boat (2.7kw) and a Honda 2kw generator connected to the AC1 input to provide the power when solar doesn’t keep up.

The Multiplus runs the dive compressor (3 phase motor driven by a single to three phase VFD) easily on its own.

When I’m not running the dive compressor, the multiplus honors the 8.5A input current limit I’ve set, however when I fire up the dive compressor it seems to ignore that limit and will try and pull all of the power from the generator, with little to no power assist.

Running the compressor at full speed the generator will overload and trip. If I lower the compressor speed with the VFD I can get it to a point where the genny can just keep up at around 10A, with the multiplus saying it’s assisting by maybe 200W on top of the 2000W from the gen. It's not ideal running the compressor this slow.

So it appears that power assist is doing a little bit, but no where near enough and the input current limit is being ignored. I can turn the input current limit right down to 4 and the behaviour doesn't change at all.

The minimum input current limit for my 5k is supposed to be 3.9A and I’m on firmware 430. Any ideas?

RCD keeps tripping when on sustain ( ESS quattro 8000)

Have a couple of quattros with ESS Assistant. What it happens often is that when in sustain mode and receiving power from the mains the RCD trips quite often specially when using appliances as the washing machine, micro wave, dish washer.

The RCD is a Hager 2P 40A 300mA AC type.

Running latest firmware.

RCD Tripping randomly

I have just about installed Multiplus 48/1200/13 and hooked it up to Li-ion 14s1p batteries.

It has been working perfectly in UPS mode and pass through. To test the capacity, I turned off the mains and the UPS kicked in, I let the system run - till the cut off voltage was reached.

When I turned on the grid/mains - the RCD (on the mains consumer unit) tripped. It did this a few times. I disconnected the load and the same happened (rocker switch in ON position). Then I switched it to charger and it did not trip.

I tried various combinations and unfortunately - the RCD tripping is very random and not reproducible.

AC in comes from the grid

AC out goes to feed a total of 250W (a few pumps)

Any input or help would be appreciated.

Compatibilité Générateur et Multiplus II


Mon motel est connecté au réseau électrique et je dispose de deux GE de 30kVA et 20kVA respective qui sont sollicités selon le besoin avec un démarrage manuel.

Je souhaite ajouter à l'installation existante 24x325Wc en deux sous champs couplés à 2 MPPT 250/100, 28kWh de stockage, 3*3kVA Multiplus II en configuration triphasée .

1) Pourriez-vous me dire à propos de mon schéma câblage coté AC, si mes équipements et les utilisateurs seront suffisamment protégés de tous les risques possibles (contacts indirects, surcharge + court-circuit + défaut à la terre ) ?

2) Pour la protection AC-in des Multiplus II que j'ai choisi , Victron préconise 32 A pour chaque Multiplus II. La configuration triphasée permettra t-elle de foisonner les courants entre phases? ce qui en réalité me permettra d'avoir sur chaque phase plus de courant?

3) Mes GE de 30kVA et 20kVA sont assez vieux, est-il possible de piloter automatiquement la marche et l'arrêt avec la BMV700 ou le CGX?

4) Avec ces onduleurs on va « rétrécir » la puissance max disponible en tête de TGBT : 32 A avec SNE/GE et 32+13=45 A avec SNE/GE+Victron, alors que jusqu’ici ils étaient limités à 50 A (disjoncteur en tête du TGBT). Quelles mesures devrait -je prendre?

Merci pour vos réponses

Generator and Multiplus II compatibility


My motel is connected to the electricity network and I have two GEs of 30kVA and 20kVA respectively which are requested as needed with a manual start.

I would like to add to the existing installation 24x325Wp in two subfields coupled with 2 MPPT 250/100, 28kWh of storage, 3 * 3kVA Multiplus II in three-phase configuration.

1) Could you tell me about my AC wiring diagram, if my equipment and users will be sufficiently protected from all risks (indirect contacts, overload + short circuit + earth fault)?

2) For the AC-in protection of the Multiplus II that I have chosen, Victron recommends 32 A for each Multiplus II. Will the three-phase configuration make it possible to increase the currents between phases? what will actually allow me to have more current on each phase?

3) My 30kVA and 20kVA GEs are quite old, is it possible to automatically control the start and stop with the BMV700 or the CGX?

4) With these inverters we will “narrow” the maximum power available at the head of the main switchboard: 32 A with GRID/ GE and 32 + 13 = 45 A with GRID/ GE + Victron, whereas until now they were limited to 50 A (circuit breaker at the head of the TGBT). What precautions should I take?

Will the generator auto-start retry?


I have a 5kVA Easy Solar with (amongst other things) a Hyundai 6kW Diesel generator. The CCGX is still on the v1.x firmware (which I'm going to upgrade but there's no internet at the property so haven't got around to it yet!). Most of the time the generator will auto-start without issue, however, recently I had an issue where the charger didn't latch on to the AC from the generator. This meant that the generator just kept running while the CCGX just kept waiting.

It looks like there is functionality in the newer v2.x firmware to "Detect Generator at AC input" which will raise an alarm. Could anyone shed some light on the actual behaviour of this function? Particularly:

  • Does the alarm turn off the external relay?
  • Does it retry?

I'd been considering building a simple circuit to do the retry but hopefully I won't need to if it's built in to the unit.

All help appreciated!

Generator disconnect

Good day,

I've got the following system:

3 x 10KVA Quattro's


30kWh Lithium battery (freedomWon)

25KVA FAW (charging limit of 4kW per phase to preserve the generator at approx. 50% running mode) Generator comes on at 20% SOC automatically, stops at 75%

10kWp PV (with 2 x 250/100 Mppt's)

It seems that the Quattro disconnects the generator as soon as the load draws more than 4kW on any phase when the generator is running, then tries to connect again. It will only connect when the load is reduced.

Is there a way to set the victron system that it maintains a constant charge by default (currently set at 4kW per phase), but allows more power from the generator when required for the load occasionally?

Hope it makes sense?

One solution I thought of is to put each geyser (1 per phase) on contactors disconnecting automatically when the generator comes on

Can GX generator start/stop feature control AC in of Quattro?

Hello all,

For a setup on a yacht, I want to control the AC in 2 of the Quattro so that during the sunny hours of the day, the shore power does not charge the Quattro. The result is that during the day only my solar panels charge the batteries.

I enabled in the Venus GX the feature generator start/stop, in such a way that the generator starts at 18.00 and stops at 08.00 hrs. I then set AC in 2 in the GX to generator. I am assuming this then controls relay 1 of the GX and switches it on and off based upon the indicated hours.

I then wired relay 1 of the GX to the auxilary relay of the Quattro.

With VE-configure, I added the following assistant to the Quattro:


Will this work? Will the AC in 2 be ignored from 08.00 till 18.00 hrs?

Quattro in off-grid operation but AC input (Grid) is always present as back-up


We are to install an off-grid PV system using 15VA Quattro, lithium batteries, and Fronius inverters. The site has grid available, hence we would want to use it as the back power supply.

We would want the AC Grid to be used by system during the following conditions:
1. Battery SoC < 20%, grid back-up to disconnect at SoC > 80%

2. Load > 12KW, grid back-up to disconnect at Load < 10kW

I read that there is an "Ignore AC Input" setting that we could possibly use to program the Quattro. Has anyone done this before?
Or do we need to use the relays and use contactors to connect /disconnect the grid to/from the Quattro?

Thanks in advance.

Maximum AC input voltage without damage

Scenario 1: You have an RV with 120/240 split phase shore power. You plug into a 120/240 volt receptacle but the neutral is floating. So what you get between each leg and neutral could be anywhere between 0 and 240 volts.

Scenario 2: You have an RV with 120 volt single phase shore power. Because of a misfire, what you end up with is 240 volts between neutral and hot.

I'd expect the Multi to reject the AC input but will damage to the unit occur?

Multiplus ignores AC input when battery is too low

I have two multiplus 24/3000/70-50 and two MPPT 250/60 with 300amps of 24v lithium batteries and a color control . It's a 50amp RV with a each multiplus connected on L1 and L2. I have an issue that only happens when I am connected to shore power and run the batteries too low.

A few times I've overloaded the AC input by running too many appliances including air conditioners and that trips the shore power breaker. This usually happens when I am on 30amp shore power, even if I set the input current limit to 30amp max. Because the system works so well it switches over to my batteries and I sometimes don't notice. It eventually drains the batteries and shuts off the system with the low power alarms. Once this happens I can't get the shore power to charge the batteries any more. I reset the breaker so that there is power AC in 1 but the multiplus won't accept the power input. At this point usually the multiplus is off and the switch for "on/off/charger only" won't do anything. I have to use a jumper cable on the terminals of the multiplus to power it back on. Once it is on it still does not accept the AC shore power input to charge the batteries and I have to wait until the solar panels charges them enough that it will allow AC in again. Even with both multiplus on, resetting the switches, and seeing main on, the color control still shows AC input at 0 and state is off. However, the solar input works fine and once the batteries get recharged to a certain level it accepts the AC input again.

I assume that the batteries have to be restored enough for the system to return to normal but why would it accept solar in and not shore power in to charge them? Obviously this creates a problem when it happens at night because I have to wait until the sun comes up in the morning to charge the batteries. Shore power, generator or any input on AC in 1 will not work until the batteries recover.

So two things I'd love to fix. 1. How can I get the multiplus to stay on when I have shore power but batteries are low? Why would I need to jump it? 2. How can I get the multiplus to accept AC input when the batteries are dead? Shouldn't AC input work all the time?

Genset frequency at 53.1Hz. Multi does not turn on

I have a client installation which is a pretty standard 48/5000 Multiplus 2 with ESS.

There is a changeover switch from a genset which is manually operated in the event of a prolonged national grid failure.

For all intents and purposes the Genset is installed as if it is the national grid.

Except, - The Multi does not recognise the Gender and sees the Grid as failed. The genset output is 23x volts and 53.15 Hz at no load

Out National grid code NRS097 stipulates the Multi to disconnect at low Hz 47 and high Hz 52

I suspect that due to the Genset output being 53.15Hz that the Multi recognises this as out of the acceptable parameters.

How can I fix this?

Can I create an identical Grid code but with high Hz cut off being say 54Hz?

Generator Auto Start Feature Request

I have routinely been using the Battery SOC as the trigger to start and stop my generator, and it works great, with one issue. As a long term off grid system that is a hybrid of generator and solar, the system can go several cycles without synchronizing the SOC function of the battery monitor. This has only a minor effect on the generator start function, but it can have a significant effect on exactly when the generator shuts down.

It would be great if there was an option to shut down the generator based on the tail current into the batteries. At a constant absorption voltage, this will result in a more consistent REAL battery SOC at the end of the generator run cycle than relying on the battery monitor which might be out of synchronization.

Induktionskochfeld mit Landstrom und / oder Generatorstrom wie am MultiGrid anschließen?

Auf meinem Boot habe ich einen 7kw Induktionskochfeld verbaut.

Der Betrieb soll folgender Maßen geschehen.

2. Der Landanschluß ist getrennt, über einen 8kw 3Phasen Generator von Fischer Panda möchte ich alle vier Kochfelder betreiben. 2 Phasen für das Induktionskochfeld, die Dritte lädt derweil die Batteriebank 24V/360Ah mit Hilfe eines Skylla TG24/50 und einem Sterling AB24/60.

Die grundsätzliche Umschaltung zwischen Landstrom und Generator geschieht direkt nach dem Trenntrafo über einen automatischen Sterling Umschalter Prio1, Prio2 und Prio3 (nicht genutzt).

Das MultiGrid kann über sein AC2 Ausgang eine Phase trennen, wie mach ich das aber bei Generatorbetrieb mit der 2ten und dritten Phase?

Als Maschinenbauer habe ich leider nur sehr wenig wissen über die Möglichkeiten der Bordelektrik.

Ich würde mich freuen jemanden zu finden, der mir bei dieser und evtl. zwei drei weiteren Fragen weiterhelfen kann.

Mein Boot wurde elektrisch komplett überarbeitet, leider ist mein Schiffselektriker kurz vor Fertigstellung erkrankt und komplett ausgefallen.
