That is a BEAST of a system fair play those are some amps gettign smashed!! One thing I will say I've noticed on my Victron 24v inverters are they see to lose 25+% of the power in or power out due to inneficiency - the other system I have with an RS48/6000 is SOOOOOOO much more efficient it's quite bonkers. I'd like to do a test etc for people to actually see the difference as I believe most people don't realise they're throwing away between quarter and a third of their power use with the older kit's poor roundtrip efficiency?
Victron low frequency, transformer based inverters are so much more advanced and longer lasting than the low budget EG4 6000XP inverters that everyone else seems to be hyping.
Low frequency transformer inverter is an old style almost vintage, definitely not advanced, that would be the case for "transformerless" high frequency models. However, victron has higher endurance for lower efficiency. It's a tradeoff
Great setup. Something with victron inverters that often trips people up is they are measured in kva not watts and I believe the power factor is 0.8, so a victron 48/5000 actually only puts out around 4000 watts
Yes, exactly. The continuous power output of an MP II 5000 is 4000 watts. It shuts off relatively quickly at 7000 watts, but it can sustain 5600 watts for a relatively long time but at only 86% efficiency, although I'm not sure for how long.
This is an amazing setup. You are so lucky to be able to test all of this on the bench first to build confidence for final your implementation. As you have invested so much, i would recommend extending your warranty (Victron provide extended warranty called 5+5). I've applied this to all my equipment. Hope you make another video of your final implementation on your boat.
using multiple amp clamps, we observed each inverter splitting the load equally. 33%/33%/33% +/- 2%. We had read elsewhere that inverters would tip in progressively as the demand increased but that not what we experienced.
hey brother.. ive been replaying your vids on this setup for weeks now learning and taking notes.. Thanks for uploading this!!! but, i have a question im hoping you can answer regarding these same inverters,.. when wired 3 x in parallel single phase, and the 5-10-15 kw load is applied as you did, does the master inverter max out and THEN start requesting more power from the slaves? or is the load distributed equally between the 3 automatically
While I am a relative novice in this field, I would argue that load sharing across multiple inverters will allow individual inverters to last longer before failure (service life). As well, if one fails (regardless of inverter/ brand), then you still have power across two or one inverter (if two fail), compared to no power at all. If a single high power inverter fails, you are dead in the water (in perhaps mission critical applications). In addition there are size and weight concerns if you are installing a single high power inverter yourself vs. multiple smaller, lighter, more compact inverters.
@@Sailing_SY_Meltemi Resistive loads are the easy way to test and present a very unrealistic load. Unless you are using resistive heating only on your inverter (WOFTAM) then not proving much. Put real-life load simulation that means the use of reactive loads. You know, the ones that show the difference between high-frequency and low frequency inverters and the real currents needed to feed them.

That is one hell of a setup. What is the purpose of it? Will it power a building, or power a boat, etc? Or is it just for testing purposes? Also, can I ask what bus bars those are (brand/ model #)?
Hi there. All of these Victron and REC-BMS components will be installed in my boat. I have a few hundred dollars into wiring and circuit breaker boxes to be able to tie into the grid in the hangar that will not be reused. Plus, some of the test equipment was purchased to make it easier to test and generate the data I needed.
❤ what an amazing demonstration. Ty for sharing

Great feedback and good to know.

Cool water heater test
Thanks 👍
Would have been nice to see how well the Inverters actually shared the load = 33% ?
using multiple amp clamps, we observed each inverter splitting the load equally. 33%/33%/33% +/- 2%. We had read elsewhere that inverters would tip in progressively as the demand increased but that not what we experienced.
@@Sailing_SY_Meltemi Wow. That is really good news.

My experience is that the load requested is distributed across all three inverters, more less equally
I am surprised that they shut off at 7000 watts, they are a low frequency inverter and should have a way better surge level
I'm told that they will run at 10% over, based upon heat
10% surge on a low frequency inverter? Seriously? It should be 2-300%
@@Kanuka-ForestThat was not a 10% "surge". That was 110% continuous. A big difference.
I have seen low frequency inverters that surge to 300%
@@Kanuka-Forest Yes, we know that. But, you don't understand ... there was no *surge* testing done in this video.
I'm curious to know why you chose 3x 5000 MP2 inverters over a single larger 15000VA or 2x 8000/10000VA inverters. For redundancy perhaps?

Everyone tests with resistive loads only.....
Thanks for the reply, but I do not understand your point.

How much did this test setup cost?
Is this going into a boat, or is it purely to see what can be done with these components?
