Multi Compact parallel compatibility

May I connect parallel two Multiplus Compact 12/1600/70-16 (both CMP121620000), one of them is HQ15131FPJI and second HQ16428BNP4. They are more than 1 year apart in production, will they work ?
Is there a website with compatibility chart ? Where should I ask for checking ?

Multi Compact Solid Alarm Light

I have 2 Compact Multis 24/1600 in parallel, all working fine, now the slave has a solid red Alarm Light, I reconfiged the master to standalone and it is fine, Have tried disconnecting both AC and DC for a day or so- no change, VEconfig cant now detect the broken multi (tried different UTP cables and ports, to be clear it goes straight to solid alarm when turned on to either inverter or charger only- no other lights flash, was plugged into shore power at the time.


Any thoughts thanks??

Grid Setpoint not tracking very well when running Parallel Multiplus

Started with a single MultiPlus-II 48/5000/70-48 and would maintain fairly well desired grid draw of about 50W with a steady load.

I now have two unit's in parallel, build dates are within about a week of each other (2022) and running 497 firmware.

Overall it seems to work and is stable apart from the grid setpoint tracking. With it set to 10W it will vary between 50-100W when the general draw is about 1000W. With a 4000W draw it will bounce around between 100-300W and so on with higher loads.

Are the unit's fighting each other to balance the load?


  • Running in ESS mode,
  • 6 x Pylon 3k Batteries
  • Smartsolar MPPT VE.Can 150/82 rev2
  • ET112 Grid Energy Meter before consumer unit
  • 240V single phase.
  • AC input is 20A MCB via 2.5mm2 cable to each inverter
  • AC Out 1 on both units connected together but not used which leads to an emergency outlet.
  • AC Out 2 are not connected at-all
  • DC side is 70mm2 cable, identical lengths.

40A Solar AC current sensor when used in parallel multiplus config.

Hi All,

Quick question regarding the 40A current sensor (measuring PV AC into L1).

When using 2 48/5000's in parallel, the ESS assistant is loaded onto both units after configuring them to work in parallel; however should the AC current sensor assistant also be loaded onto both or (I Guess) just the master unit into which it is connected ?

Just after a bit of clarity on this one - thanks

AC common with two Multi-plus?

I'm offgrid and have two Multi-plus. On the AC out I ran one multi-plus hot to L1 and the outher multi-plus to L2 in a breaker panel. Can I run both commons to a bus and then to the common in the breaker box, which is bonded to earth ground?

3 x Multiplus II parallel error 17

I have 3 MULTIPLUS II in parallel and can only get 2 to operate, whenever I connect a particular unit I get error 17.

The dc cables are all the same length and type and the RJ45 cables are all purchased and new. 2 units work fine in any position but the 3rd fails in any position. They are all running the same firmware (was 494 now 497, no change to behaviour)

Any ideas for what I can check next?

Cheers

EasySolar , installation en triphasé

bonjour , récemment inscrit, merci de votre accueil prochain à cette question :)


j'ai actuellement 3 easysolar 5000 en 48v pour trois circuits indépendants en mono 230v

chacun a son installation avec son jeu de batteries et ses panneaux

je souhaiterais réunir tout ça et passer l'ensemble en tri-phasé

cette installation est off-grid, il n'y a pas d'arrivée externe

j'ai vu des videos avec des multiplus mais pas des easy solar,

faudra t il condamner certaines parties de deux d'entre eux (color control ...)?

si quelqu'un a déjà fait un montage ?

merci de votre aide

PV Inverter dropping from CCGX, batterys charging - Rewired and new CT same issue

So basically what happened was my pv dropped off my ccgx about 2 month ago. I isolated the mains a few times and put it back on and there it was back on my screen. Until this stopped working. Then I thought the Carlo Gavazzi energy meter was the problem so I brought a new AC CT sensor specifically for the solar.


Got this working last night it detected my panels it fed them into battery it discharged them then I woke up this morning to check it was working. and no something happened overnight it dropped the meters 7am this morning. FFS sick of this now really need some support on it.


Any help appreciated

Dual Parallel MultiPlus AC Wire Size Advice

230 volts 50hrz boat with shore power and generator with a separate AC source panel and AC Distribution panel.

I am installing 2 MultiPlus 1600/70 unit in parallel (location constraints close to the battery bank made it optimal to install 2 smaller units).

Question: what would be the optimal wire size to run from a: The AC source output to the multiplus(s) and b: from the multiplus(s) back to the AC distribution panel?


The distance between the panels is approximately 3-3.5 meters one way. At what point would you add the junction box to split the AC in wires, the AC out wires and would you keep the same wire size throughout.


Thanks in advance for any advice,

Generator wiring with 2 x 5kva multiplus

Hi guys,


I am expanding an existing system by adding an additional 5kva multiplus in parallel single phase. There will now be 2 x 5kva multis. The existing 6.5kva generator works fine with the existing system. I would like to know the best way about installing either a larger generator and connect it to both multis for charging and operating ac loads in poor solar days. I am reading a lot of people have great difficulties getting this to work correctly on the other posts. This is a complex system with ac coupled solar edge inverters. Dc coupled victron mppts and expanding to 32kwh of BYD batteries. Everything works well at the moment. I do not want the generator to malfunction once we parallel the inverters and have a master and slave setup.


Please advise and assist if possible. SLD would be great and some tips for the VE config would be awesome.
