bad victron smartsolar 100/50 firmware update?

By "class" do you mean that price range? If you want something more reliable it is going to cost a bit more.
no, I meant, for ~2000W, 24V input, 800W worth of (4) panels, that is reliable. Looking both options: inverters only and complete systems.

I don't care much about the cost. The reliability is the most important -- preferably complete kit, with power outlets included (beginner friendly) -- like the vid by Wil, above.

ok, for inverters only, this looks appealing https://a.co/d/5ngOHK1 -- but I'm looking for a nice LDC interface for the load and issues -- -- seems fairly good, otherwise, with a lot of positive reviews.

would also love recommendations for anan all-in-one, with an eye on a future setup -- with reliability in mind. I've spent inordinate time & your time, kind folks -- but learned a good deal of stuff -- for something that largely turned out to be a defective inverter.

thanks kindly,
Cos

Electric motors have surge associated with startup - typically about 5X run. That still shouldn't cause a problem, but since it's the largest, it might be uncovering another issue.

Are all connections between batteries and batteries and inverter of the appropriate size and properly torqued? A 2000W inverter needs (2000W/12.8V/.85) wire capable of handling 183A, and your interconnects between batteries should be the same.

Loose connections also cause problems. Ensure everything is properly torqued. If you made any crimps, inspect them for quality.

yeps, the Novopal 2000/4000 is undersized, for my spike loads.
(I ended up opening the inverter and it was all great, no parts fried, etc, but noticed 4 tiny transformers and 4 corresponding capacitors, corresponding to the 4 power outlets for the inverter out. That's when it hit me that likely, all of these were designed in parallel, so basically any one output would be rated 500W/1000W.

I'm thinking this comparable Renogy inverter, https://www.amazon.com/dp/B096MKPQ1M?ref_=cm_sw_r_cp_ud_dp_GE0V8JF7V2PYHG0P51TT&skipTwisterOG=1, rated at 3000/6000w, with 3 power outputs, is constructed the same, meaning 1000W/2000W per power outlet -- so hopefully this should be adequate for the load). Probably growatt's are constructed different, with all power coming out through one wire, I'm assuming.

thanks bunches for the insight, @sunshine_eggo .
 
That's a lightweight high frequency inverter too. The 6000W surge is mostly meaningless, but the 3000W should be legit.

Renogy is fine, but it's not a favorite of the forum. Will has a list of inverters on his site:


This is also a favorite, also known as the "reliable" brand. I have the 24/2000 version, and I was very happy with it:

friends don't let friends buy renology :) -- because it fails one month prior to warranty expiring and it will take you 2 months to get a response from them.

does anyone know if Wil's recommended inverter of 4000w, and 4 outlets, means that it likely has 4 transformers at 1000W max each, much like the Novopal? seems too much of a coincidence, 4000W/4 Outlets. Ha ha... I just noticed ... it looks like the Amazon picture of their newer model, the inside, indeed has 4 transformers (so likely the older version has the same architecture) . Hopefully this be OK for appliances that have spikes over 1000W for limited time... I guess a stress test may be in order :-)

thanks kindly.

Manual:


Each outlet is limited to 1500W

Worth noting that is has a L-N-G terminal block that will deliver the full inverter power.

The WZRELB had the same terminal block. I wired a 30A RV plug receptacle to it and just plugged my RV into it, so I could draw the full 2000W. Had no issues running the 1600W microwave and all 12V loads through the RV's converter.
 
Go blue if you are worried about surge. Victron is top tier and won't fail on you. For surges, believe the 3 x surge factor for 30 seconds verse the 2 x surge factor for less than 5 seconds.

ok, got the 4000W beast: https://a.co/d/6yRw3xs
thanks kindly for the L-N-G knowledge tidbit.
