Multi HS19 Solar 15k

Even though I am firmly of the opinion that all inverters should be installed by professionals—since no ESS operates within the safety extra-low voltage range—I could imagine that connecting high-voltage batteries using insulated, ready-made cables might be safer than using unprofessionally crimped 48V cables intended for very high currents.

I completely agree with that.

However, sales drive everything, so the reality is a bit different :joy:

Meanwhile, in North America, I wouldn’t expect to see them until 2030. Even if we got a 208V or 480V version, I can’t use any solar panels we buy today. I do have some older 420W bifacial panels on the roof of my shop with Isc=10.45A I could reuse. Still, I would need input and output transformers to use the HS19 here. The transformers cost more than the inverter. haha. Oh well.

But even for European installations, I am puzzled by some of the design choices. I heard whispers of the HS19 series more than two years ago, and some of the design choices in the model announced yesterday are likely five years old. It’s a start at least. But no ability to parallel the units leads me to think these are going to be limited to small sites who just need to run a few pieces of small equipment or a small three-phase house.

I’ll keep my fingers crossed for more rapid development going forward.

PV shortcircuit current and MPP current being the same value feels like a typo

Or the ones that didn’t skipped classes and learned something in school…

Here’s a nice marketing thing… Probably the one showed at fairs.

And Victron…
I know that many things are done on the last leg, but it should be a little more consistency on the presentation photos…

It seems the Multi HS19 is designed for use with “commercial” solar panels that are higher voltage and lower current.

This is similar to the Fronius Primo models which have a second MPPT tracker with a 12.5A current limit which doesn’t suit high current solar panels

This I what Victron showed yesterday and I guess that will be included in the manual:

Pylontech have HV batterys like the H48050 made for series connections

Yes, but those don’t function without the control module, which is not presented on the picture.
Therefore Joe, the “expert wannabe”, could try to use normal power modules, like US2/3/5000, in series.
Those who are assigned to make the manuals should be very careful not to create confusion that could lead to the loss of property and/or life.

This will also mean that a new section on the community rules will appear and that any technical discussion on the HS19 will be forbidden and will be referred to the (not always) qualified personnel of the distributor/installer?

Kidding and poking the bear… :grinning_face_with_smiling_eyes:

I was quite interested but noticed the low Isc…

I was looking to make 2 stacks of pylon h3 but you need a pylontech hv combiner box. That box does not allow inverters that need more than 600V according to the specs in the manual…

I think this is too niche tbh

Still an intresting product in my eyes, although i like LV systems more.

Its also a pretty expensive device compared to victron low voltage options…

Curious what the multi rs 19 will be priced at, would be nice for installers if they also made a 3ph version of that model!

You kinda get three Multi RS Solar 48/6000, so I think it has a reasonable price.

This is the 3-phase model

In NL its €1600 more than 3x multi rs 48/6k plus battery is more expensive too

No i mean a 3ph version of the multi rs 19 not the hs 19 in this topic :blush:

I think the development and marketing departments consider demand, competition, and feasibility, apparently don’t see the potential.

By the way, this model is not a star either without its own battery management and parallelization system.

Boy what a fierce competition on Intersolar 2026…
You have to be there to see the overwhelming variety of products…
Three days is definitely too short to see everything.

Now I realize something from efficiency point of view for HS19…
For maximum figures:
The inverter has 98% efficiency and that for 15kW means 300W loss…
The MPPTs have 99% efficiency and that for 32kW means 320W loss…
A total of 620W, mostly in heat.
And the real figures are usually less, so to vent sometimes 1kW of heat is something…

As for the price, on my country, some have announced figures of over 4000 euros for a HS19…
See below, where the exchange rate is about 1:5.

In extremis, imagine how many thousands of kilometers/miles can go an electric car with 4000 euros… Over 50000 km.
More exactly, on my country, charging slowly at residential price/power, over 70000 km.
So lately I am keep asking myself this question… is it worth to invest in such things at such prices?
After 70000 km some are thinking about SOH of the battery and the faint idea of changing the car…
And as the charging of a car is a smooth process, without load variations, a Chinese AIO with 6kW MPPT and 6kW inverter is more than capable to do it without hickups at almost 10x less price.

Do similar products from other manufacturers have better efficiency?
100% efficiency is impossible, there always is something.
