Multi RS19 Solar 48/6000/100-450/80

Bonjour

petit question concernant le nouveau produit

Multi RS19 Solar 48/6000/100-450/80

qui commence a être disponible (en précommande) en Allemagne

il parle de la plage mppt 64V -450V et une tension de démarrage de 120V, justement c’est sur cette dernière valeur qui me pose soucis car je suis actuellement a 80V et ne souhaite pas passé a 120V (mini)

avez vous des informations sur cette baisse possible de démarrage?

car si plus de 120V en théorie cpi obligatoire en France, sauf si les mppt ont bien une isolation galvanique?

Merci

le rs19 est un multirs en rack 19 pouce. il a donc bien le cpi et l’isolation galvanique entre bus dc et batterie.

J’ai plus l’impression qu’il parle du Multi RS Solar 6kVA.

Dans “Multi RS19 Solar 48/6000/100-450/80”, à l’exception du 19 et du 80, ça corresponds aux spécification du Multi RS Solar. De plus, la description qu’il en fait correspond à ce produit et non au nouveau HS19. Le Multi RS Solar, n’a rien de nouveau. Il est en vente depuis quelques temps déjà.

@Joe, pourrais-tu préciser de quel produit tu parles.

If its like an rs450/100 then it will need 120V to start the tracker but then just need to maintain a minimum of 65V from there.

ne pas confondre rs19 et hs19, c’est deux nouveau produits mais c’est des produits bien différents !

Ok. Y-a-t-il déjà eu une annonce officielle pour le RS19 ? Je n’ai rien vu sur les News.

Les spécifications sont quasi identiques au Multi RS Solar, à l’exception du format et du raccordement batterie.

Je parle bien du nouveau modèle en rack 19 pouces.
Merci pour l’information du CPI ainsi que d’une isolation galvanique

J’aurais également une question concernant la tension de démarrage :
Sait‑on déjà si ce modèle pourra démarrer à environ 80 V ?

Autre point : j’utilise actuellement 2 strings de deux panneaux DMEG 500 Wc (2×500 Wc).
Le problème est l’intensité, qui atteint déjà 13–14 A, alors qu’en théorie le matériel supporte 12 A en fonctionnement normal (et 16 A en court‑circuit).
Comment cela se passe‑t‑il au niveau de la garantie si l’intensité dépasse régulièrement les 12 A ?

Concernant le raccordement batterie :
Il semble que les câbles soient similaires à ceux utilisés par les batteries Pylontech.
Victron prévoit‑il de commercialiser les connecteurs batterie permettant la connexion aux batteries Victron NG 300 Ah ?
Et qu’en est‑il du diamètre de câble, sachant que Pylontech recommande du 25 mm² qui est insuffisant dans le cas de la batterie victron ng 300Ah?

It’s disappointing; I thought Victron would make an effort to release the RS19 with a higher MPPT input current than for the Multi RS Solar, but no such effort was made.

As for the usable MPPT current limit, it means it won’t draw more than 12A from the panels. In other words, it will throttle the output, so will never you get the maximum output your panels could produce since DMEGC panels are rated around 13.5A impp. But since panels rarely give the maximum of their power it is not really an issue

To me , the possible issue is with the isc current of the panels vs the rating isc current of the mppts

Isc for the mppt is 16A, and your panels are rated 14.2A isc. On the paper it is inferior to the 16A limit, but the best practice is to add a safety factor of 1.25 to the current of the panels, which increases the isc of the panels to around 17.5A

This safety factor is applied because the panels can produce more than the rated isc current when irradiance goes beyond STC values (>1000w/m2)

Maximum operational PV input current limit 12 A

Isn’t this a typo?
Because now, and even five years ago, it is impossible to find solar panels with such a current on the market.

This means constant generation losses.

Not a error, and yes energy loss.

Surrealism

I am comparing the new Multi RS19 and Multi HS19 for an east-west PV system with 25 AIKO 485 W modules.

AIKO 485 W:

  • Vmp: 34.3 V
  • Voc: 40.9 V
  • Imp: 14.15 A
  • Isc: 14.88 A

The RS19 supports 16 A Isc but only 12 A operating current and 450 V PV voltage.

The HS19 supports 600 V, which is ideal for 12/13 module strings, but the datasheet specifies only 13.5 A MPPT current and 13.5 A short-circuit current.

Is the HS19 officially compatible with these AIKO modules, or are the current limits a hard restriction?

Which inverter would Victron recommend for this application?

Use the ‘Victron Mppt Calculator’

With 25 large panels, you could end with the Smart Solar RS 450/200 (48volt) battery charger and a 48 volt inverter of your choice.

Thank you. Unfortunately, the MPPT Calculator does not include the new Multi HS19 Solar yet.

My question is specifically about the HS19 hardware limits.

The AIKO 485 W modules have an Imp of 14.15 A and an Isc of 14.88 A.

The HS19 datasheet specifies 13.5 A MPPT operating current and 13.5 A short-circuit current.

Does Victron officially approve these modules for use with the HS19, or are these current limits strict hardware limits that make these modules unsuitable?

If its anything like the mppt design in the rs450/100 its a soft limit and the rs450 manual specifically talks about edge cases where you may want to exceed that:

16A operational limit

20A reverse polarity limit

30A short circuit limit (in correct polarity).

Fundamentally assuming you have a 350V string for example the 4kW per tracker limit would limit you to around 11.5A real world anyway, even if you had two parallel strings on the tracker.

Thanks. That makes sense for the operating current.

However, my main concern is the 13.5 A short-circuit current specification of the HS19.

My AIKO modules have 14.88 A Isc, which is above the datasheet value.

Can anyone from Victron confirm whether this is an absolute hardware limit or simply the recommended design limit?

You know the hs19 is for high voltage batteries only? 650-1000Volt DC, wich required special switches, fuses, cables, DC connectors, many safety requirements, special battery room…there are not many low voltage DC ESS installers who dare their hands on high voltage ESS systems.

High Voltage ESS systems are for large scale systems with huge battery capacity and over 100 solarpanels, not for the smaller home system.
